Self-supporting zipper packaging bag resistance to boiling sterilization function: liquid jelly filling after 30 minutes pasteurization (temperature :85℃-90℃). Self-supporting zipper packaging bags must be able to withstand the above conditions of disinfection and sterilization process, no leakage, broken packaging.
Self-supporting zipper bag sealing function: Sealing is the basic function of self-supporting suction pocket. Long time storage is not allowed to have leakage package, leakage phenomenon. The heat sealing data of self-supporting zipper bags must have excellent low-temperature heat sealing function and heat sealing strength (heat sealing temperature) ≤135℃, (heat sealing strength of PET composite products ≥50N/15mm, NY composite products ≥60N/15mm).
Self-supporting zipper packaging bags have excellent weather resistance: vast territory, diverse environment, diverse climate, more and more products are exported to foreign countries. Self-supporting zipper bags need to be adapted to different environments and climates around the world. Only in this way can the products be sold around the world.
The jelly will inevitably appear extrusion, accumulation and decline in the process of filling, packaging, transportation, sales and consumption. The self-supporting zipper packaging bag is required to have excellent compression and impact resistance function to avoid damage.
