Poor sealing of hot filling and heavy packaging bags
Release time：2022-05-17

We have a heavy packaging customer who is filled with 25kg modified nylon particles and hot filled at 90 ℃. The customer reported that they often imagine that the edges of our heavy packaging bags may not be tightly sealed and come off. Later, we solved this problem through some process adjustments.
