26" x 28" + 4" BG 2.5 Mil Expandable Poly Mailers Case of 100

These white 26" x 28" poly mailers are expandable courier bags for e-commerce and order fulfillment, with a peel-and-seal closure. A bottom gusset expands for bulkier items like boxed shoes, folded sweaters and bedding. They're a good fit for outerwear, bedding and large bundles of soft goods.

The 2.5 mil co-extruded film is white outside and silver-gray inside, so contents stay private, and it's water resistant and tamper-evident: once sealed, it can't be opened without tearing. Each measures 26" x 28" plus a 4" bottom gusset. Choose a mailer an inch or two larger than the item each way so it seals flat.
