BSTech Heavy-Duty Mailing Bags | 240 x 325 mm (C4) | 50 Microns | 2200 pcs

Optimize your everyday fulfillment with the BSTech Heavy-Duty Foliopak Mailing Envelopes (FB02). Tailored specifically for high-volume e-commerce stores, warehouses, and logistics hubs, these C4-sized shipping bags offer the perfect combination of durability, privacy, and speed for your standard-sized parcels.

Manufactured from a tough 50-micron thick co-extruded plastic film, these mailers easily resist punctures, tears, and stretches during transit. The advanced dual-layer design features a clean, bright white exterior that gives your packages a highly professional look, backed by a deep black interior that ensures 100% opacity. This blackout design keeps the contents entirely hidden from view, guaranteeing customer privacy and reducing the risk of theft.

The integrated self-adhesive strip provides a permanent, tamper-evident seal. Once closed, the high-tack glue creates a secure bond that cannot be peeled open without visibly tearing the bag, ensuring your goods arrive exactly as they left your warehouse.
