Poly mailers are a convenient alternative to traditional packing boxes, offering a lightweight and easy-to-ship solution. These envelopes are made of flexible polyethylene (LDPE) material and feature a self-sealing design. They are particularly well-suited for shipping non-fragile items, apparel, and t-shirts.

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 5,000 mailers.

Ordering mailers that are slightly too small is one of the most common mistakes. The 3rd dimension is often overlooked when making the calculation. In addition to the width and length of your item, you need to consider 2 pertinent and commonly overlooked factors:

  1. The height or thickness of your item need to be kept in mind. Add this number to the dimension that is closest to the mailer’s inside dimension.

Example: If your item is 6″ x 6.5″ x 2.5″ thick, add thickness to both width and height (2.5 + 6 = 8.5″, 2.5 + 6.5 = 9″) You will need a mailer with at least 8.5″ width, 9″ length.

  1. Manufacturing variances occur and also have to be sondiered. Since there is no way to guarantee exact dimensions throughout an entire manufacturing production run, you should account for an extra 0.25″ on each side of item just in case you end up with a mailer on the smaller side.

Calculating the best mailer size can be a challenge. Don’t hesitate to contact us for help!
