These 12 x 15 1/2 inch polyethylene mailers deliver a lightweight, durable shipping envelope for e-commerce and retail outbound operations. At 2.5 mil thickness, the construction resists punctures, moisture, and tearing through standard transit handling. High-strength seams hold firm even when contents press tightly against the mailer walls.

The white exterior accepts inkjet, thermal, and laser-printed address labels without pre-treatment, and takes stamps and handwritten ink cleanly. A self-seal pressure-sensitive adhesive closure forms a tamper-evident bond with no tape or equipment needed. The built-in tear strip lets recipients open packages without scissors or tools — a detail that improves the unboxing experience for apparel, soft goods, documents, and lightweight retail items.

The silver interior lining adds a secondary barrier layer that helps protect contents from moisture and light abrasion during transit. Mailers lay flat for compact storage on packing benches or in supply rooms. Sold in packs of 100, and ships via parcel carrier.
