BSTech Heavy-Duty Mailing Bags | 350 x 460 mm (C3) | 50 Microns | 1200 pcs

Upgrade your e-commerce shipping setup with the BSTech Heavy-Duty Foil Mailing Envelopes (FB05). Designed specifically for professional online merchants, fulfillment operations, and warehouses, these spacious C3-sized bags offer exceptional strength, top-tier security, and a clean presentation for your customer deliveries.

Crafted from a robust 50-micron thick co-extruded film, these mailers are built to withstand the bumps, scrapes, and rough handling of global transit networks. The smart dual-layer construction features a pristine white exterior that makes shipping labels and barcodes stand out clearly, and a solid black interior that ensures 100% opacity. Your items remain completely blacked out, providing total privacy and extra security from dispatch to final delivery.

Packing is fast and stress-free thanks to the high-tack, tamper-evident self-adhesive strip. Once the protective backing is peeled and the lip is pressed down, the permanent bond locks shut—any attempt to open it will visibly tear the plastic, preventing sneak-theft.

Features & Benefits

• Total Content Privacy: The deep black inner lining blocks out light entirely, keeping valuable or personal merchandise hidden from outside eyes.

• Heavy-Duty Protection: A thickness of 50 µm provides solid protection against water, rain, dirt, and heavy stretching without ripping.

• Rapid Fulfillment: Save hours on the packing line with the easy peel-and-seal strip. No packing tape or scissors needed.

• Crisp Retail Look: The smooth white surface easily accepts thermal labels, adhesive shipping pouches, or permanent markers without smearing.

• Cost-Efficient Bulk Pack: Delivered in a large volume carton of 1,200 pieces, keeping your cost-per-package low and your packing stations fully stocked.
