Countermeasures of contents leakage or deterioration caused by incomplete heat sealing of bag making

Release:admin Source: Unknown  Release time:2023-04-10
In the process of bag making, incomplete heat sealing will cause the contents to leak or deteriorate. For this kind of situation, it is mainly caused by the poor anti-pollution heat sealing property of the film, or the inappropriate resin used in the inner sealing layer. Countermeasure: Use the film with good pollution resistance and heat sealing. Generally speaking, LDPE has moderate resistance to pollution heat sealing, EVA has good resistance to pollution heat sealing when VA content is large, LDPE also has good resistance to pollution heat sealing, ionic resins and metallocene polymers have excellent resistance to pollution heat sealing.
