Poly Mailers
The single-layer LDPE mailer is the most shipped packaging format in e-commerce. It weighs almost nothing, so it keeps shipping costs down. It keeps moisture and dust out. And it prints beautifully, which turns every parcel into a branded touchpoint.
We supply the full range: standard poly mailers, frosted apparel mailers, tamper-evident security mailers, returnable mailers with a second adhesive strip for e-commerce returns, and fully custom printed versions in up to 8 colors.
Every variant is produced to your spec: size, film thickness, color, closure and print. For fulfillment operations running automated lines, ask about our wicket mailers, the same films supplied on wickets for machine packing. And if your market is pushing toward paper, our honeycomb padded envelopes cover the same jobs in a mono-paper format. Which film gauge to choose, and where poly mailers are collected for recycling, is covered in our e-commerce packaging guide.
Why poly is still the workhorse
- Lightest mailer format there is: grams, not tens of grams, per parcel.
- Waterproof film keeps rain, moisture and dust off the product.
- Prints in up to 8 colors, edge to edge, for the strongest brand impression per dollar.
- Tamper-evident closures available for confidential or high-value shipments.
- Returnable versions with a second adhesive strip cut return-packaging cost to zero.
- 40 to 120 micron films matched to the load, so you never pay for plastic you do not need.
