"Paper or Plastic?" It used to be a question at the grocery checkout. Now, it is a strategic decision for every e-commerce operations manager.
Brands are under immense pressure to remove plastic.Consumers love the "organic" look of paper, while governments enforce stricter rules like the Plastic Packaging Tax regulations to curb waste.However, procurement teams know the hidden truth: sustainability isn't just about the material; it's about the entire lifecycle.
If you switch to paper but your damage rates skyrocket due to rain, or your shipping costs double due to weight, have you really made a sustainable choice?
At Adsure, we manufacture both [Kraft Paper Auto-Mailers] and [Recycled PCR Plastic Bags]. We don't have a bias—we just want you to pick the right film for your machine and your product. Here is the honest breakdown.
Round 1: The Case for Paper (The Premium Choice)
Paper packaging, specifically Kraft Paper, is the undisputed king of "Unboxing Experience." It feels premium, natural, and eco-friendly.
✅ The Pros:
Curbside Recyclability: This is the #1 driver.Unlike soft plastics, paper is universally accepted in bins and aligns with standard How2Recycle labeling guidelines, making it easy for consumers to dispose of responsibly.
Brand Image: It immediately signals "We care about the planet" to the consumer.
Rigidity: Paper keeps its shape better than soft poly, which can be good for certain apparel items.
❌ The Cons:
Weather Vulnerability: Standard paper absorbs water. If a package sits on a rainy porch, the product inside is at risk.
Storage Volume: Paper rolls are bulkier than plastic rolls, taking up more warehouse space.
Dust: Paper generates dust during the auto-bagging process, requiring more frequent machine cleaning.
Round 2: The Case for PCR Plastic (The Performance Choice)
Plastic often gets a bad reputation, but in terms of carbon footprint, it is often the winner. Comprehensive lifecycle carbon analysis shows that lightweight plastic requires significantly less energy to transport than bulkier alternatives.
Modern options, like our [GRS-Certified PCR Auto-Mailers], use Post-Consumer Recycled resin, giving waste plastic a second life.
✅ The Pros:
Ultimate Protection: Plastic is waterproof, tear-resistant, and puncture-proof. Ideal for international shipping.
Lower Carbon Logistics: Plastic is significantly lighter than paper. Shipping 1,000 plastic packs requires less fuel than 1,000 paper packs.
Operational Efficiency: Poly film rolls hold 2-3x more bags per roll than paper, meaning fewer changeovers and less downtime for your autobagger.
❌ The Cons:
Recycling Confusion: Most soft plastics need to be dropped off at store collection points (Store Drop-off), not curbside bins.
Perception: Even if it's recycled, some consumers simply dislike the look of plastic.

Decision Guide: Which Should You Choose?
Still undecided? Here is our recommendation based on 30 years of automation experience:
👉 Choose [Kraft Paper Auto-Mailers] If:
Your brand strategy focuses on "Plastic-Free" messaging.
You ship non-fragile, dry items (like t-shirts, socks, or bedding).
You are willing to pay a premium for the "Curbside Recyclable" label.
👉 Choose [Recycled-Content Auto-Mailers] If:
You need maximum durability (e.g., shipping shoe boxes, electronics, or hardware).
You want to minimize shipping weight and freight costs.
You operate high-speed automated lines and want fewer roll changes.
Automation Note: Can My Current Machine Run Paper?
This is the most common question we get from operations managers.
The answer is: Yes, but the material matters.
Paper behaves differently than plastic—it has zero "stretch" and creates higher friction. If you feed a low-quality paper roll into a standard autobagger designed for poly, it will likely snap or jam.
That's where Adsure engineering comes in.
We don't make the machines, but we have mastered the material that runs on them. Our Kraft Paper Auto-Mailers are specifically engineered with:
Optimized Slip Coating: Reduces friction to help the paper slide smoothly through feed rollers.
Precision Perforations: Designed to tear cleanly at the bagger's separation point without causing web breaks.
Whether you are running an Autobag®, Sharp™, or Pac Machinery system, our paper films are "drop-in ready" alternatives designed to work with your existing equipment settings (with minor heat/speed adjustments).
Conclusion
Paper vs Plastic Mailers：There is no "bad" material, only the "wrong" application. The most sustainable packaging is the one that gets your product to the customer safely, without damage/returns, while minimizing waste.

FAQ
Q1:Is Kraft Paper packaging more expensive than recycled plastic?
Generally, yes. Kraft Paper Auto-Mailers are typically a premium option, costing more per unit than standard plastic mailers due to higher raw material and manufacturing costs. However, many brands find the investment worthwhile because it eliminates the need for extra marketing materials—the "plastic-free" unboxing experience itself becomes a powerful brand statement that resonates with eco-conscious consumers.
Q2: Is paper packaging always more sustainable than plastic?
Not necessarily. While paper wins on curbside recyclability and consumer perception, it often has a higher carbon footprint due to its weight and volume during transport. PCR Plastic Mailers are significantly lighter, requiring less fuel to ship and less energy to produce. The "most sustainable" choice depends on whether your priority is plastic-free branding (Paper) or minimizing total lifecycle carbon emissions (PCR Plastic).
Q3: I ship clothing internationally. Should I use paper or plastic mailers?
For international shipping, we generally recommend PCR Co-Ex Plastic Mailers. Paper mailers, while durable, are vulnerable to moisture and rain during long transit times or when left on doorsteps. Plastic offers superior water resistance and puncture proofing, ensuring your goods arrive safely without water damage, which ultimately reduces return rates.
Q4: How does switching to paper affect my warehouse efficiency?
You should expect some operational changes. Because paper is thicker than plastic film, a roll of paper holds fewer bags than a roll of plastic of the same diameter. This means your operators will need to perform more frequent roll changeovers (about 2-3x more often). Additionally, paper can generate dust, so we suggest a slightly more frequent cleaning schedule for your autobagger's sensors.
Q5: What does "PCR" mean in your plastic bags, and is it certified?
PCR stands for Post-Consumer Recycled resin, meaning the plastic is made from waste that has already been used and recycled, rather than virgin oil. Adsure’s plastic mailers are GRS-Certified (Global Recycled Standard), ensuring the recycled content is verified and traceable. This helps you meet government regulations like the UK Plastic Packaging Tax while maintaining the durability of plastic.
Q6: I’m undecided. How can I compare the performance of both materials?
Don't guess—test. Adsure offers a mixed sample kit containing both our Kerbside Recyclable Paper and 100% PCR Plastic auto-bags. We encourage you to run them on your actual machine and perform drop/water tests with your specific products. Contact our team to request your sample kit today.
