Self-Adhesive Courier Bag

1. Quick sealing：The bag opening features a built-in adhesive strip. After removing the release liner, pressing it down seals the bag without the need for tape or heat-sealing equipment, improving packing efficiency.

2. Tamper-evident and theft-resistant：Once the self-adhesive strip is sealed, it is difficult to open without visible damage, effectively preventing contents from being swapped or stolen during transit.

3. Waterproof and dustproof：The plastic outer layer provides good resistance to water, dust, and grease, keeping the contents clean and dry.

4. Lightweight and cost-saving：The bag is extremely lightweight, helping to reduce shipping costs calculated by weight, while also taking up less storage space than cardboard boxes.
