What is the reason why pe shrink film is easy to break Release time: 2019-09-09 PVC shrink film is very common in the current packaging market, such as the outer packaging of cosmetics, stationery, door and window outer packaging, aluminum outer packaging, and various All kinds of stainless steel pipe outer packaging will be used. Because PVC shrink 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 and fully automatic heat shrinking machine, and it can be tightly fixed on the surface of the product. However, some PVC shrink 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 product quality will be unstable, and the durability will be poor, and it will be easy to break; 2. The shrink film is made 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, it will be easy to break; third, the temperature and time during heating are not well controlled, resulting in product failure Qualified, easy to break; Fourth, the product is not brand new materials, produced with recycled materials, or added recycled materials, resulting in reduced tensile force and easy to break.
