Waterproof Shipping Courier Bag
Waterproof shipping courier bag is a self-sealing poly mailer made from PE film with a strong adhesive that maintains stickiness in hot or cold weather. The reinforced edge seal resists tearing and water penetration, so contents stay protected during transit in foggy or rainy conditions. The bag requires no additional packaging material and seals securely without tape, reducing packing time and mailing costs.
- Self-adhesive seal stays strong in hot or cold weather, preventing tampering during transit
- Reinforced edge seal resists tearing and keeps contents secure in wet or humid conditions
- No extra tape or packaging needed—seals instantly and securely at the bench
- Lightweight and compact, reducing dimensional weight charges on courier and air freight
Include the carton size and the monthly volume and the reply will contain a format recommendation, not just a price.

How It Compares With the Alternatives
Where another material is the better answer we say so, because a returned shipment costs more than a lost order.
| Corrugated cardboard box | Lighter weight and lower dimensional freight cost; no need for tape or additional void fill |
|---|---|
| Standard poly mailer without reinforced seal | Reinforced edge prevents tearing during handling and transit |
| Taped poly bag | Self-sealing eliminates tape use and reduces packing time |
