Methods to improve the sealing strength of PE heat shrinkable film

The products made by PE heat shrinkable film manufacturers can play the role of packaging goods. Its transparency is relatively high, especially the gloss, but we find that sometimes the strength is not enough. At this time, we need to increase the strength of the product. Now we Let’s take a look? 　　 Actually, there are many reasons why we increase the strength of our products. During the heat sealing process, we need to control the manufacturing process steps, especially the pressure of the hot pressing is moderate, because if the pressure is not uniform, this may cause Air bubbles are generated in the heat-sealed area, which affects the sealing strength. Secondly, it should be noted that the heat-sealing time cannot be too long. The bonding between the heat-sealing layers will be stronger, but it is not suitable for too long to avoid wrinkles.　　 If we find that the PE heat shrinkable film is damaged during use, we need to pay attention to placing it in the garbage collection bin for recycling to ensure that there will be no environmental pollution.
