The reason why the heat sealing strength is high but still drop and break
In the case of higher heat sealing temperature, the heat sealing strength is higher. However, the bag was damaged during the drop test. On the contrary, in the case of lower heat sealing temperature, although the heat sealing strength is lower, it can also meet the requirements of customers, but the packaging bag is not damaged during the drop test. This phenomenon shows that when the heat sealing temperature is high, the pressure of the heat sealing knife is under the action. The inner PE film with heat sealing function becomes thin and brittle after high temperature melting and extrusion, which leads to damage during drop test. Therefore, in the process of bag making, it is necessary to adjust the appropriate heat sealing temperature and pressure to produce products with excellent comprehensive performance.
