BSTech Heavy-Duty Mailing Bags | 310 x 420 mm (A3) | 50 Microns | 1500 pcs

Streamline your e-commerce shipping with the BSTech Heavy-Duty Foil Mailing Envelopes (FB04). Engineered specifically for high-volume online stores, fulfillment centers, and warehouses, these A3-sized shipping bags provide an uncompromised balance of strength, security, and professional presentation.

Constructed from a premium 50-micron thick co-extruded plastic film, these mailers offer superior tear and puncture resistance compared to standard economy bags. The dual-layer design features a clean white exterior for a professional look and effortless labeling, paired with a solid black interior that ensures 100% opacity. Your contents remain completely hidden from view, guaranteeing privacy and security during transit.

Equipped with a powerful, tamper-evident self-adhesive strip, packing is fast and secure. Once sealed, the permanent adhesive cannot be opened without visibly tearing the bag, acting as an excellent deterrent against theft.
