Polyethylene film product quality

Polyethylene film is very common in the current packaging market, such as cosmetic outer packaging, stationery outer packaging, door and window outer packaging, aluminum outer packaging, and all kinds of stainless steel tube outer packaging. Because polyethylene film has good shrinkage, strong tensile force, and simple and easy to operate packaging, it only needs to be heated with a high-power blower or a semi-automatic, fully automatic heat shrinking machine, and it can be tightly fixed on the surface of the product. However, some polyethylene film packaging products are easy to break with a slight touch. What is the reason? I think there are four main reasons:

1. The quality of the shrink film itself. If the temperature is not adjusted properly during production, the quality of the product will be unstable, the durability will be poor, and it will be easy to break;

2. The shrink film is too thin. In order to save packaging costs, some businesses will require manufacturers to make the shrink film thinner, but if the shrinking force of the thin shrink film is too large after shrinking, it will be easy to break;

3. The temperature and time of heating are not well controlled, resulting in unqualified products and easy breakage;

4. The product is not brand new, but is produced with production material or added with production material, resulting in reduced tensile force and easy breakage.
