Courier envelopes are designed for the safe, convenient shipping of documents, clothing, books, money, securities, photographs and other goods. Their defining feature is a thick film combined with a special adhesive sealing strip. The bag cannot be opened without visible damage, even if the adhesive strip is frozen or heated. They are made from a special three-layer film that is completely black on the inside, so the contents cannot be seen through the material.
Benefits and features of courier bags:
- Airtight and moisture-resistant
- Reinforced adhesive layer on the flap
- Sturdy side seams that resist tearing
- White outer surface, making it easy to write the address and add labels
- Guaranteed privacy of the contents (surface is 100% opaque)
