Self Adhesive Seal OPP Bag
Self adhesive seal OPP bag is a pre-formed plastic bag with a strong, permanent adhesive strip that seals the opening without tape or heat. The bag is made from transparent OPP film, so contents are visible for retail display or inventory checks. It is used for packaging small to medium items where a secure, clean seal is needed at the point of packing or shipping.
- Self-adhesive seal eliminates need for tape, heat sealing, or string tying at the packing bench
- High gloss finish enhances product presentation for retail or gift packaging
- Puncture resistant film protects contents during handling and transit
- Waterproof and moisture proof barrier keeps contents dry in humid environments
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.
| Tape-sealed plastic bags | Self-adhesive bags seal faster and more consistently without tape, reducing packing line time and material waste |
|---|---|
| Heat-sealed bags | No heat sealing equipment needed—ideal for manual or low-volume packing lines |
| Paper bags with tape | OPP film is waterproof and moisture proof, while paper bags degrade in humid conditions |
| Ziplock bags | Self-adhesive OPP bags are lower cost and do not require a plastic zipper mechanism |

Align the self-adhesive strip with the top edge of the bag
