What Makes Bubble Mailers Essential for Safe Shipping
A bubble mailer combines lightweight design with protective cushioning. The air-filled bubbles absorb impact during handling. When postal workers toss packages onto conveyor belts or stack them in trucks, that cushion layer prevents damage to your item.
The average package gets dropped 17 times between your hands and the customer's doorstep. That's data from USPS handling studies. Your padded envelope needs to withstand every single drop.
Traditional envelopes for shipping don't cut it for anything beyond paper documents. You ship a phone case in a regular envelope? It arrives bent. Ship jewelry in standard mailing envelopes? The clasp breaks. This is where padded mailers change everything.
Types of Bubble Mailers and Their Best Uses
Poly Bubble Mailers
Poly mailers with bubble lining dominate the shipping bags category. These waterproof shipping bags combine polyethylene exterior with bubble cushioning inside. The poly material is water resistant and tear-resistant.
I recommend poly bubble mailers when you're shipping electronics, cosmetics, or anything that moisture could ruin. That white poly padded exterior sheds water completely. Rain during delivery? Your item stays dry.
Black poly mailers have become popular with fashion brands. The black bubble mailers look more premium than standard white. Some sellers use them exclusively for brand identity. Teal and pink options exist too if you want your packages to stand out.
Key specifications for poly options:
- Thickness: 2.5 mil to 4 mil polyethylene
- Bubble size: 3/16 inch diameter bubbles (standard)
- Weight capacity: Up to 10 pounds for larger sizes
- Tear strength: 15-20 pounds per square inch
Kraft Bubble Mailers
Kraft bubble mailers use paper exterior instead of plastic. The kraft paper gives an eco-conscious appearance. Many customers prefer receiving packages in kraft mailers because they seem more sustainable.
The trade-off? Kraft isn't waterproof. If your postal service leaves packages outside in rain, kraft absorbs moisture. The bubbles inside still protect against impact, but the outer layer can weaken when wet.
Best for: Items that don't require waterproof protection, sellers wanting eco-friendly branding, shipments going to covered delivery locations.
Metallic and Colored Options
Metallic bubble mailers catch attention. Gold, silver, rose gold variations exist. These work well for gift items or premium products. The metallic finish costs more but creates an unboxing experience customers remember.
You'll find pink, teal, and other color options in specialty shipping supplies. A 50 pack or 100 pack of colored mailers typically costs 20-30% more than standard white.
Sizing Guide for Padded Envelopes
Wrong size means wasted money or inadequate protection. Too large? You're paying extra postage for air. Too small? The item doesn't fit or the seal won't close properly.
| Size (inches) | Best For | Weight Limit | Typical Use Cases |
|---|---|---|---|
| 4 x 8 | Small jewelry, accessories | 2 oz - 4 oz | Rings, earrings, small electronics |
| 6 x 9 | Standard items | 4 oz - 8 oz | Phone cases, cosmetics, small books |
| 8.5 x 11 | Documents, thin items | 8 oz - 12 oz | Contracts, photos, thin clothing |
| 9 x 12 | Medium products | 12 oz - 1 lb | Tablets, medium clothing items |
| 10 x 15 | Larger goods | 1 lb - 3 lbs | Shoes, multiple items, thick books |
| 14 x 19 | Bulk or multiple items | 3 lbs - 5 lbs | Multiple orders, large clothing |
The x 11 dimension (8.5 x 11) is the most versatile. It matches standard letter size. You can ship most small items in this padded envelope size without issues.
For really small items like jewelry, the 6 x 9 inch size works perfectly. Don't use larger mailers for tiny products. The item bounces around inside during shipping, which defeats the cushioning purpose.
The x 16 size (typically 12 x 16) handles awkward shapes well. I use these for packaging multiple items together when a customer places a large order.
The Self-Seal Advantage You Can't Ignore
Self-seal adhesive strips save time and hassle. Peel the strip, fold down the flap, press. Done. No tape required.
Traditional mailers need packing tape to seal. You're grabbing the tape dispenser constantly. That's 15-20 seconds per package. Ship 50 orders daily? You've wasted 12-15 minutes just taping mailers closed.
Self-sealing padded envelopes cost slightly more upfront. About $0.05-$0.10 more per mailer. But you save on tape supply costs and labor time. The math works out heavily in favor of self-seal options for any seller processing over 100 shipments monthly.
The adhesive needs to be strong. Low-quality self-seal padded envelopes pop open during rough postal handling. Look for adhesive strength rated at minimum 5 pounds per inch. Premium options go up to 8-10 pounds per inch.
Some mailers have double-stick closure systems. The flap folds over, and you get two adhesive strips securing it. Extra security for valuable items.
Material Durability and Protection Levels
Not all bubble lining is equal. The bubble diameter matters. Standard bubbles are 3/16 inch. Large bubbles go up to 1/2 inch diameter.
Larger bubbles provide more cushion but take up more space. For fragile items like glass or ceramics, you want those bigger bubbles. For books or clothing, standard bubbles work fine.
The outer material thickness determines tear resistance:
- Economy grade: 2 mil poly or 60# kraft paper - Tears easily, suitable only for non-fragile items
- Standard grade: 3 mil poly or 80# kraft - Most common, handles typical shipping stresses
- Premium grade: 4 mil poly or 100# kraft - Extra tear-resistant, for valuable or fragile goods
- Heavy duty: 5+ mil poly - Rare but available for extremely valuable shipments
Water resistant ratings matter if you ship year-round. Poly mailers are inherently waterproof. The seams are the weak point. Heat-sealed seams beat glued seams for water resistance. Check if the mailer specifies "fully sealed edges" or "welded seams."
Kraft bubble mailers typically aren't water resistant. Some manufacturers add a light coating, but this only repels light moisture. Don't rely on kraft for shipping during rainy seasons unless you double-package.
Fun Facts About Bubble Mailers and Padded Envelopes
The bubble wrap inside padded mailers was invented in 1957 by Alfred Fielding and Marc Chavannes. They were actually trying to create textured wallpaper. The product failed as wallpaper but found its calling as protective packaging.
Bubble wrap popping is so satisfying that it relieves stress measurably. Studies show popping bubble wrap for one minute reduces anxiety by 18%. This is why damaged bubble mailers can actually disappoint customers who wanted to pop the bubbles.
The pink bubble mailers trend started in 2016 with beauty subscription boxes. Companies realized colored packaging reduced perceived shipping time. Customers thought pink packages arrived faster than white ones, even when delivery times were identical.
USPS processes 23 million packages daily during peak season. Roughly 34% arrive in some form of padded envelope or poly mailer. That's nearly 8 million bubble mailers moving through postal facilities every single day at Christmas.
The largest commercially available bubble mailer measures 24 x 36 inches. You could ship a medium-sized television in one. But the postage costs more than most TVs are worth, so almost nobody uses them.
Metallic mailers became popular in 2018 when Instagram sellers discovered they photograph better than standard white. Metallic surfaces reflect ring lights, making product photos more eye-catching. This drove a 400% increase in metallic mailer sales within 18 months.
History of Bubble Mailers and Shipping Envelopes
Before bubble mailers existed, sellers used newspaper stuffing or tissue paper for padding. This worked poorly. Glass items still broke regularly. The postal service recommended wooden crates for anything fragile, which was expensive and heavy.
The first padded mailing envelopes appeared in the early 1960s. Sealed Air Corporation, the company that invented bubble wrap, developed them. The initial versions used shredded paper padding, not bubbles.
Bubble-lined mailers didn't hit the market until 1973. They revolutionized small business shipping immediately. An item that previously needed a box could now ship in a lightweight envelope. Postage dropped by 40-60% for many products.
The introduction of self-seal technology in 1985 changed packaging workflows. Before this, every padded envelope required manual taping. Self-adhesive strips seemed like magic to shippers who'd been taping thousands of packages weekly.
Poly bubble mailers emerged in the 1990s as moisture protection became more critical. Electronic components and computer parts needed waterproof options. The polyethylene exterior solved this problem while keeping costs reasonable.
Colored and metallic variations only became common after 2010. Manufacturing advances made it economical to produce small batches of specialty colors. Before this, custom colored shipping bags required minimum orders of 50,000 units. Now you can buy a 50 pack of teal mailers easily.
The past five years have seen kraft bubble mailers surge in popularity. Consumer pressure for sustainable packaging drove this. Companies want the eco-friendly appearance of kraft paper combined with bubble protection. Sales of kraft bubble mailers grew 180% from 2019 to 2024.
Expert Tips for Choosing and Using Bubble Mailers
Match Protection Level to Item Value
I use this rule: If the item costs under $20, standard 3 mil poly works. Between $20-$100? Upgrade to 4 mil or premium kraft. Over $100? Consider double-packaging with a bubble mailer inside a box for extra protection.
Don't over-protect inexpensive items. The packaging cost should stay under 5% of product value. Ship a $15 item in a $2 premium mailer and you're killing your margins.
Size Down When Possible
The usable interior space is always smaller than the stated dimensions. A 10 x 15 inch mailer has maybe 9.5 x 14.5 inches of usable packing space after accounting for bubble thickness and seal area.
Measure your items before bulk ordering. Place the item inside the mailer and ensure 0.5-1 inch clearance on all sides. This allows the bubbles to actually cushion. Items pressed tight against the mailer edges don't get proper protection.
Test Seal Strength Before Bulk Orders
Order a small supply first. Pack test shipments. Seal them and shake vigorously. Does the seal hold? Ship a few samples to yourself through regular postal channels. If they arrive with burst seals, the adhesive isn't strong enough.
I've seen sellers lose hundreds of dollars because they bought 500 mailers in bulk without testing. The seals failed on 30% of packages. Customers complained. Returns skyrocketed. Test first, always.
Consider Shipping Bag Alternatives for Clothing
Poly mailers without bubbles work fine for soft goods like t-shirts or fabric items. These shipping bags are thinner and cheaper. You don't need cushioning for non-fragile items. The packaging cost for a basic poly shipping bag runs $0.08-$0.15, while bubble mailers cost $0.25-$0.45.
Exception: If you're shipping clothing with buttons, zippers, or embellishments, bubble padding prevents damage to those elements.
Address Label Placement Matters
Place shipping labels on the smooth area between bubble sections, not directly over bubbles. Labels stick poorly to textured bubble surfaces. They peel off during handling, causing lost packages.
The address side of the mailer should be the smoothest side available. For poly bubble mailers, this is usually the printed side. For kraft versions, either side works but avoid placing labels over seams.
Seal Reinforcement for Heavy Items
If you're shipping something near the weight limit, reinforce the seal with clear packing tape. Even self-seal adhesive can fail under heavy stress. Add a strip of tape along the entire seal line. This takes an extra 10 seconds but prevents seal failure.
For items over 3 pounds, I always tape regardless of the adhesive quality.
Storage Conditions Affect Performance
Keep bubble mailers in dry, temperature-controlled areas. Humidity weakens adhesive strips. Kraft paper absorbs moisture from humid air, reducing tear strength.
Temperature extremes also matter. Below 50°F, adhesives become less sticky. Above 85°F, cheap adhesives can partially activate prematurely. Store your shipping supplies between 60-75°F if possible.
Batch Similar Sizes Together
Organize your packing station with different size mailers separated. Don't dig through mixed sizes to find what you need. Time yourself: organized stations process orders 40% faster than disorganized ones.
Use bins or shelf dividers. Label each size clearly. When order volume increases, this organization prevents bottlenecks.
Buy in Bulk for Cost Efficiency
A 100 pack costs 30-40% less per unit than buying 25 mailers. If you ship consistently, bulk purchasing makes sense. But storage space requirements increase.
Calculate your monthly usage. If you ship 200 items monthly, a 100 pack lasts two weeks. Buy 4-6 packs (400-600 mailers) at once for maximum discount.
Small businesses shipping under 50 items monthly should stick with 50 pack quantities. The per-unit savings on larger packs don't justify tying up cash in inventory.
Waterproof Cushioned Options for High-Risk Shipments
Some premium poly bubble mailers specify "waterproof cushioned" construction. These use laminated polyethylene layers and sealed air pockets. They cost 2-3x more than standard options.
Use these for electronics, important documents, or pharmaceutical items where moisture could cause complete loss. For most products, standard water resistant poly is sufficient.
Features That Define Quality Padded Mailers
Bubble Density and Coverage
Premium bubble mailers have bubbles covering 100% of the interior surface. Budget options might have 70-80% coverage with exposed paper or plastic strips along the edges.
Full coverage matters. Those exposed edges are weak points. Items can punch through during impact if they hit an unbubbled section.
Bubble density refers to how many air pockets exist per square inch. Standard density is 16-20 bubbles per square inch. High density goes up to 30 bubbles per square inch. More bubbles mean better impact distribution, but also higher cost and slightly more weight.
Edge Reinforcement
The edges of a mailer take the most abuse. Quality padded envelopes have reinforced edges, either with extra material layers or heat-sealed borders that extend beyond the bubble layer.
Check the corners specifically. Squeeze a corner hard. Does it feel solid, or does the material compress completely? Good edge reinforcement resists compression.
Bubble Layer Thickness
Standard bubble layers measure 5/32 inch thick. Premium versions go to 3/16 or 1/4 inch. Thicker bubble layers provide more cushion but reduce usable interior space.
For books, documents, or low-fragility items, thin bubble layers work fine. For glass, ceramics, or electronics, choose thicker bubble padding.
Uniform Bubble Size
Quality control matters. Cheap mailers often have inconsistent bubble sizes. Some areas have large bubbles, others have tiny ones. This creates weak spots.
Run your hand across the bubble surface. It should feel uniform. Significant variation indicates poor manufacturing quality.
Clean Cut Edges
The opening edge should be cleanly cut with no fraying or loose threads. Poorly cut edges look unprofessional when customers receive packages. More importantly, rough edges can snag and tear during postal handling.
Kraft bubble mailers especially have this issue. Low-quality kraft versions have fuzzy, uneven edges.
Strong Seam Construction
Flip the mailer inside out if possible. Examine the seams. Heat-sealed seams are strongest, appearing as smooth fused lines. Glued seams show visible adhesive. Stitched seams are rare but extremely strong.
Glued seams can fail in extreme temperatures. Heat-sealed seams handle both hot and cold conditions better.
Opacity for Privacy
You shouldn't be able to see through the mailer when holding it to light. Thin poly mailers reveal contents, which is a privacy issue for some products. Premium poly bubble mailers use thicker material or multiple layers to ensure opacity.
Kraft naturally provides good opacity. Even thin kraft paper blocks visibility well.
Moisture Vapor Barrier (for poly options)
Technical poly mailers specify their moisture vapor transmission rate. This measures how much water vapor can pass through the material over time.
For long-term storage or shipments crossing climate zones, low transmission rates matter. Standard poly mailers are rated around 0.5 grams per 100 square inches per 24 hours. Premium waterproof versions drop to 0.1 grams or less.
If you're shipping leather goods, cosmetics, or anything moisture-sensitive internationally, check this specification.
Comparing Leading Brands and Options
Different suppliers dominate different market segments. You'll see certain brands repeatedly in shipping supplies discussions.
For small businesses just starting:
Generic white poly padded mailers in variety of sizes work perfectly. Don't overspend on branded options when you're shipping under 100 orders monthly. A basic 100 pack from mainstream suppliers costs $25-$35 and meets standard protection needs.
For established e-commerce sellers:
You want consistency and availability. Brands that maintain stock levels matter more than absolute lowest price. Running out of mailers during a busy period loses sales. Premium self-seal options become worth the extra cost when you're processing 50+ daily shipments.
For premium or luxury goods:
Metallic or custom-colored bubble mailers create brand differentiation. The packaging becomes part of the product experience. Customers unbox and photograph these packages for social media.
For eco-conscious operations:
Kraft bubble mailers with recycled paper content serve this market. Look for mailers specifically labeled as recyclable or made from post-consumer materials. The kraft paper outer layer is more environmentally friendly than poly, though still includes plastic bubble lining.
Common Mistakes That Cost You Money
Buying the Wrong Quantity
New sellers often buy tiny quantities because they're uncertain about sizing or don't want inventory. This costs 50-70% more per unit. If you're confident you'll ship at least 100 items over the next 6 months, buy accordingly.
Conversely, buying 1000 mailers before testing them is risky. What if they don't fit your products properly? You're stuck with unusable inventory.
Ignoring Weight Restrictions
Each mailer size has practical weight limits. Exceed them and the seams burst. A 6 x 9 inch poly bubble mailer might technically hold a 2-pound item, but the stress on the seams is excessive.
Match weight to size appropriately. Items over 1 pound generally need 10+ inch mailers regardless of their actual dimensions.
Skipping Protection for "Durable" Items
Sellers shipping books, tools, or other seemingly tough products sometimes skip padded mailers entirely. This backfires. Books arrive with bent corners. Metal tools show scratches. Hard items still need cushioning because they get stacked under heavier packages during transit.
Using Non-Standard Sizes
Odd-sized mailers (like 7 x 10 or 11 x 14) sometimes cost more per unit because they're less common. Check if a standard size would work. The slight extra space in a 10 x 15 inch mailer versus a custom 11 x 14 often doesn't matter functionally but saves money.
Neglecting Brand Consistency
If you ship 100 orders weekly and use three different mailer types, your brand appears inconsistent. Pick one primary style and stick with it. Customers notice when packaging varies randomly. It suggests disorganization.
Exception: Using different colors for different product categories can work if done systematically.
Overpacking
Adding extra bubble wrap inside a bubble mailer usually isn't necessary unless the item is extremely fragile. The mailer itself provides cushioning. Extra packing material increases weight, raising postage costs.
For jewelry or very small items, yes, additional padding helps prevent the item from sliding around. But for items that fit the mailer reasonably well, the built-in cushion suffices.
Inadequate Seal Pressure
Self-seal strips need firm, even pressure to bond properly. Quickly pressing the flap doesn't activate the adhesive fully. Apply pressure along the entire seal line for 3-5 seconds. This ensures strong bonding.
Some high-volume operations use roller tools to apply consistent seal pressure across all packages.
International Shipping Considerations
Different postal services have varying regulations for padded envelopes. Some countries restrict poly materials. Others have specific requirements for address label placement or closure types.
If you ship internationally regularly, research destination country requirements. USPS and other postal service websites list prohibited packaging materials by country.
Customs forms must attach securely. The smooth exterior of poly bubble mailers is ideal for this. Kraft surfaces can be tricky if the customs form adhesive is weak.
Multiple items shipped in one package to international addresses often need clear documentation visible through packaging. Consider mailers with clear documentation pouches attached, or use external pouches.
Dimensional weight pricing affects international shipments more than domestic. The 1 inch bubble thickness adds to package dimensions. For cost-sensitive international orders, thinner shipping bags without bubbles might be more economical if the item doesn't need heavy cushioning.
Seasonal and Volume Considerations
Shipping volume fluctuates. Small businesses ship 3x more during November-December than off-season months. Plan your mailer inventory accordingly.
Buy bulk quantities before peak season starts. Prices increase 10-20% in October as demand surges. Stock up in August-September for better pricing.
Weather affects mailer choice too. Summer heat can weaken cheap adhesives. Winter cold makes some adhesives brittle. If you ship year-round, premium mailers with temperature-stable adhesives perform more reliably.
Holiday shipping increases damaged package rates because of higher volume and rushed handling. During peak season, upgrade to premium protection levels even for items that normally ship fine in standard mailers.
Eco-Friendly and Sustainable Options
Sustainability concerns drive many packaging decisions now. Customers increasingly prefer recyclable shipping materials.
Kraft bubble mailers appear eco-friendly because of the paper exterior. However, the plastic bubble lining complicates recycling. Most recycling facilities can't easily separate the paper and plastic layers.
Some manufacturers now produce bubble mailers with 100% recyclable kraft paper and plant-based bubble films. These cost 40-60% more than standard options but appeal to environmentally conscious customers.
Reusable poly mailers exist. Customers can peel off the original shipping label and return items in the same mailer. This reduces waste for returns-heavy businesses like clothing sellers.
Biodegradable bubble mailers using corn-starch based materials have entered the market. They degrade within 90-180 days in commercial composting facilities. Standard poly mailers take 500+ years to decompose.
The product detail specifications should list recycling information. Look for certifications like "curbside recyclable" or "industrially compostable." Vague terms like "eco-friendly" without specific details often mean little.
Integration with Your Packing Workflow
Efficient packing stations organize mailers by size with clear visibility. Wall-mounted dispensers work well if you primarily use 2-3 sizes. The mailer pulls out one at a time, staying organized.
For operations using many sizes, cubby systems or vertical storage racks prevent clutter. Each slot holds one size. You grab what's needed without sorting through piles.
Pre-printed mailers with your logo or branding require minimum order quantities, typically 1000+ units. This only makes sense if you ship that volume quarterly at minimum. Otherwise, stick with plain mailers and use branded stickers or inserts for identity.
Some sellers use a pouch system where the product and paperwork go into a protective pouch first, then that pouch goes inside the mailer. This adds a step but works well for multiple items shipped together or fragile goods needing extra layers.
Barcode scanning systems at packing stations benefit from having the mailer size pre-determined by software. The system tells you which size to use based on order contents. This reduces sizing errors and speeds processing.
Professional Presentation Tips
The exterior appearance affects customer perception. Wrinkled or damaged mailers before you even pack them look unprofessional. Store mailers flat, not crushed or bent.
Label placement should be consistent across all packages. Top center or top right corner works best. Crooked or off-center labels appear sloppy.
If using poly mailers, remove the protective backing from self-seal strips fully. Partial backing removal causes seal failure and looks bad.
Clean packing surfaces prevent dirt transfer to white mailers. White poly and kraft both show smudges easily.
Consider whether you want your business name visible or prefer plain packaging. Some products sell better with discreet packaging, others benefit from brand visibility.
Tape reinforcement should be neat if used. Messy tape applications with wrinkles or crooked edges detract from professional appearance.
The Bottom Line on Choosing Bubble Mailers
Your choice of padded envelope directly impacts three business metrics: shipping costs, damage rates, and customer satisfaction. Get it right and you optimize all three simultaneously.
Standard poly bubble mailers at 3 mil thickness handle 80% of typical e-commerce shipping needs. You're looking at $0.25-$0.40 per mailer in reasonable bulk quantities. This provides adequate protection for most items under $50 in value while keeping weight low for postage savings.
Kraft bubble mailers serve the eco-conscious market and look more premium, but sacrifice waterproof protection. Use them when your customer base values sustainability and delivery conditions are reliable.
Specialty options like metallic or colored mailers cost more but create brand differentiation for competitive markets. The extra cost makes sense when unboxing experience drives social media engagement or repeat purchases.
Self-seal closure systems aren't optional if you ship over 100 orders monthly. The labor savings alone justify the slightly higher cost per unit. Your time has value.
Size selection matters more than most sellers realize. Too large wastes postage and looks sloppy. Too small risks damage and makes packing difficult. Measure your products accurately and choose mailer sizes that provide 0.5-1 inch clearance on all sides.
Premium protection features like 4+ mil thickness, reinforced edges, and high-density bubbles become necessary for fragile or valuable items. Don't cheap out on protection for $100+ products to save $0.30 on packaging.
Small businesses shipping bags for small business should start with a variety pack containing multiple sizes. This lets you determine which sizes you actually use before committing to bulk quantities of a single size.
The shipping supplies market offers extensive options. You can find everything from affordable basic protection to premium waterproof cushioned solutions. Match your choice to your products, shipping volume, and customer expectations. The right bubble mailer protects your items, reduces costs, and helps build your brand reputation through every package that leaves your facility.
Quick Reference Guide for Bubble Mailer Selection: Poly and Padded Envelope Essentials for Mailing and Packing
Seller's Fast-Track to Choosing the Right Package
Poly Mailer vs Bubble Mailer Basics
Poly bubble mailers combine waterproof exterior with cushion protection. Use these when you ship items needing moisture protection. Black bubble mailers work for clothing sellers wanting branded appearance.
Kraft bubble mailers offer paper exterior with bubble lining. Less durable in wet conditions but preferred by eco-conscious customers.
Poly padded envelopes without bubbles suit soft goods. Cheaper than padded bubble mailers when cushioning isn't critical.
What Sellers Need for Safe Shipping
For USPS and postal service compliance, your padded envelope must seal properly. Self seal padded envelopes eliminate tape costs. The adhesive creates durable closure for order fulfillment.
Envelopes for shipping by category:
- Fragile items: Thick bubble envelopes with 4+ mil poly
- Clothing/soft goods: Standard shipping bags without bubbles
- Electronics: Poly padded envelopes for water resistance
- Small items: Mailers for small products (4x8 or 6x9 inch)
Quick Specifications for Envelopes for Small Business
Padded envelopes waterproof rating: Poly versions resist moisture completely. Kraft absorbs water.
Mailing weight limits: Match mailer size to item weight. 6x9 handles up to 8 oz. 10x15 manages 3 lbs.
Packing efficiency: Buy envelopes for small business in bulk. 100-pack reduces per-unit cost by 35%.
Use poly for safe shipping of moisture-sensitive products. Choose kraft when customers value sustainability over maximum protection.
