Poly Mailer Bags Overview

Lightweight, moisture-resistant, and tamper-evident, poly mailer bags are engineered mailing packs designed to streamline fulfillment and last-mile delivery. Manufactured primarily from LDPE or co-extruded PE film, they offer a strong seal, high tear resistance, and an opaque barrier for privacy—making them ideal bags to ship items in across apparel, accessories, healthcare disposables, spare parts, and documentation. Typical specifications include film thicknesses from 50–120 microns, single or multi-layer construction, permanent hot-melt adhesive closures, and optional easy-open tear strips. Sizes range from courier-friendly small formats to oversized poly shipping mailers for bulky soft goods. Customization spans logos, handling icons, variable data, and barcodes, supporting brand visibility and operational traceability.
