Heavy-Duty thickened PE Courier Mailers

  • Extra-Thick Multi-layer Construction: With a thickness range of 60-100 microns, these bags offer significantly higher tensile strength than standard mailers.

  • Ultimate Puncture & Tear Resistance: Specifically formulated to resist sharp corners and rough handling during long-distance air or sea freight.

  • 100% Opaque Privacy: The black inner lining ensures total content privacy, preventing any light from showing through the bag.

  • Industrial-Strength Destructive Seal: Features a high-tack hot-melt adhesive strip that creates a permanent bond; once sealed, it cannot be opened without visible damage.

  • Reinforced Side Seals: Explosion-proof edges ensure the bag stays intact even when packed to its maximum capacity.
