- Barrier: Good gas, water vapour and light barrier performance, effectively preventing food oxidation, moisture, deterioration and prolonging the shelf life.
- Adaptability: According to the needs of different foods, the bags can be customised with different material structures to adapt to a variety of storage conditions, such as high temperature, low temperature, freezing or freshness.
