What is a custom poly mailer?

Custom poly mailers are a lightweight, easy-to-ship alternative to packing boxes. Poly mailers are flexible, self-sealing polypropylene envelopes that are ideal for shipping apparel, t-shirts, and non-fragile items.

Our custom poly mailers are fun to design, easy to ship, waterproof, and tear-resistant. All our poly mailers feature a self-adhesive strip to speed up the shipping process and minimum orders start as low as 10 mailers.
