Product Details

Description

Our ultra-lightweight mailing bags are engineered to reduce postal costs without compromising on strength or protection. Manufactured using advanced co-extrusion technology, each bag features a 50–60 micron (220–240 gauge) thickness, delivering outstanding durability, opacity, and long-lasting performance.

Built to withstand tough shipping conditions, these bags are 100% moisture-resistant, puncture-proof, and tear-resistant, making them ideal for secure deliveries. The all-season self-adhesive strip provides a fast, hassle-free seal—once closed, the bag is permanently secured, offering tamper-evident protection for maximum confidentiality throughout transit.

Made from 100% recycled Low-Density Polyethylene (LDPE), this packaging is a reliable and eco-conscious choice. It remains fully recyclable (with the glue strip removed) while providing a high level of security and professional presentation.
