Back-Seal Bags
A back-seal pouch is formed from one folded sheet of film, with one vertical seal down the middle of the back and cross seals at both ends. It is the familiar format for instant noodles, confectionery, snacks, tea, coffee and pharmaceuticals.
The pouch uses laminated films such as PE, PET, CPP, OPP or silver foil, chosen for the level of moisture and oxidation protection the product needs. A zip, degassing valve or tear notch can be added; a gusseted version holds more than one without gussets.

Frequently Asked Questions
- How does a gusseted back-seal pouch differ from one without gussets?
- A gusseted pouch has extra folds on both sides, so it holds more. Its construction is more complex and it often uses multi-layer moisture-resistant film, so the converting cost also differs from a pouch without gussets.
- What does the price of back-seal pouches depend on?
- The price depends on the size, material, thickness, number of print colours, whether the pouch is gusseted, and the order volume. The larger the volume, the more competitive the unit price. Message the size, product and expected volume on Zalo for a KOVAA quote.
- Can back-seal pouches be used for food?
- Yes. The materials used for back-seal pouches meet food hygiene and safety standards and resist moisture and oxidation. The exact film structure is chosen for the product to be packed.
