10 x 13 poly mailers

Most 10 x 13 poly mailers are made from polyethylene (polyethylene film), which is the material most commonly described in product listings.

The standard labeled size is 10 x 13 inches (sometimes shown as 13.0 x 10.0). An expansion/gusseted option is listed as 10" x 13" x 2" with a gusseted bottom to accommodate thicker items.

They’re commonly used for shipping flat items like shipping documents, catalogs, and marketing materials, as well as non-fragile goods such as clothing, accessories, promotional items, and books.

Multiple listings state that ink, stamps, and labels adhere easily to the surface of these mailers.

Some listings describe a silver inner lining or silver inner layer that helps obscure contents and enhance confidentiality.

These mailers are lightweight, and listings highlight that their low weight and compact design can help reduce postage and overall shipping costs.
