Self-adhesive Poly Mailer

The self-adhesive poly mailer features a pressure-sensitive adhesive strip with a release liner. Remove the liner and press to seal — no heat sealer needed. Designed for e-commerce shipping, document delivery, and small item packaging. Its "peel, press, seal" design significantly boosts packing efficiency. It is a top choice for apparel, cosmetics, electronics, and more.

Made from LDPE, HDPE, or co-extruded film. Available in transparent, translucent, white, or colors. The destructive adhesive strip leaves tamper evidence once opened. Available in flat, envelope, and courier bag styles.

Compared to traditional flat bags, the self-adhesive poly mailer offers a perfect balance of convenience and cost — easy to use, no equipment needed. Widely used by e-commerce sellers, courier points, and retail stores.
