The role of heat shrinkable film

The staff of the PE heat shrinkable film manufacturer pointed out that the heat shrinkable film is more and more widely used in our lives, and its functions are becoming more and more powerful. It will be widely used in production and daily life. But what are its specific functions? The author will give you an introduction. Heat shrinkable film is used for the sales and transportation of various products, and its main function is to cover and protect the products. The shrink film must have good shrinkage, high puncture resistance and a certain shrinkage stress. During the shrinking process, the film cannot produce holes. Since shrink film is often used outdoors, it is necessary to add anti-ultraviolet agents to prevent ultraviolet rays from sunburning the product. It also has high flexibility, not easy to break, strong impact resistance, strong blast resistance, strong tear resistance, strong tensile force, and can replace box packaging in many cases. In addition, it has a large shrinkage rate, which can tightly wrap objects after heat shrinkage. If it is made into a PE pass-through bag, after heat shrinkage, the two ends of the opening can lift the objects for easy handling. The above are the uses of heat shrinkable film. After everyone understands these uses, I believe that the heat shrinkable film will also have more understanding, and it will be more convenient in the future use.
