Choosing between poly mailers and paper mailers comes down to cost, protection, and end-of-life. This guide compares the two in plain terms. You will see where each wins, where each falls short, and when to use padded versions. We cover moisture, sizing, recyclability, and total cost. Use it to match mailer type to your product and brand goals. This is your quick start to Poly Mailers vs. Paper Mailers.
Poly Mailers
Poly mailers are made from polyethylene. They are best suited for shipping non-fragile, or smaller items. Many companies like to use this type of mailer to package their goods as they are typically moisture resistant, tear-proof, and low-cost. They are also very flexible, so you can usually fit all types of different products in them. They do however provide minimal protection, so if you are needing to keep a delicate item safe it may be best to use a bubble poly mailer.
Bubble Poly mailers are the same as a normal poly mailer, but they have a layer of bubble wrap along the inside of the mailer that will provide additional cushion for the product. Most poly mailers are recyclable; however, it depends on how you recycle them. Usually they cannot be recycled curbside, but instead must go to a special drop off location that will accept them.
If you are looking for an environmentally friendly option, this may not be the best choice. Instead, you will want to keep reading about the paper mailers PAX Solutions now offers.
Pros of Poly Mailers:
- Resilient to tearing
- Moisture resistant
- Affordable
- Easy to Load / Package
Cons of Poly Mailers:
- Hard to recycle
- Minimal Protection from Rough Handling
- Static Build Up
Paper Mailers
With the growing need for environmentally friendly packaging options the paper mailer was created. Not only can you recycle them through your regular curbside service, but they are compostable as well.
Many people may think that the paper mailers would not hold up when it comes to moisture, but there are sustainable weather proofing finishes to help with that. The paper mailers are a bit more robust on their own than the poly mailers, so they do hold up to rough handling a bit better.
Just like the poly versions, there is a padded paper mailer as well if you are looking for the added protection. With this being a newer item to the market, there are however limited stock sizes available.
Pros of Paper Mailers:
- Environmentally Friendly
- Compostable & Recyclable – For national stats on recycling rates, see the EPA’s paper and paperboard data.
- Better Protection from Rough Handling
Cons of Paper Mailers:
- Limited Stock Sizes
- Higher Price Point
Industries That Utilize Poly Mailers and Paper Mailers
Apparel and soft goods. T-shirts, hoodies, and linens do well in a standard poly mailer. Fabric compresses and does not crack. If the garment has hard parts such as zippers, buttons, and rivets then it may be wise to move to a bubble poly to prevent scuffs and corner rub. Keep the fit snug so items do not shift.
Books and media. Books, journals, and boxed games have sharp corners that take hits. A padded paper mailer adds edge strength and light cushioning. It also keeps a curbside path for recycling when clean and dry.
Cosmetics in folding cartons. Bottles and compacts go inside printed cartons, but drops can still dent lids and crack hinges. Use a padded paper mailer or a bubble poly mailer. Seal liquids in an inner bag as a fail-safe. Run a simple three-drop test on your heaviest SKU and check seals and corners.
Marketing kits or mixed items. Multiple pieces add weight and odd edges. A mailer can tear or deform. At that point a small box with light dunnage is safer.
Quick rule of thumb. If it bends without damage, a mailer is fine. If it dents, cracks, or has sharp corners, choose a more robust form of shipping container.
