Is PVC hot shrink film easy to use? What are the advantages of PVC hot shrink film?

First, PVC heat shrinkable film is a good film packaging material, it has the following advantages: (1) good transparency, which can let customers directly see the packaged goods, easy for customers to choose goods; (2) close to the shape of the product, it can be applied to the packaging of various shapes of goods, and the packaging content is extensive; (3) Excellent anti-theft and dust-proof; (4) A variety of goods can be packed in a heat shrinkable bag to prevent the loss of individual small goods, but also convenient for customers to carry; (5) The selection of different resins and formulas can produce heat shrink films with different mechanical strength and functions, which can be used for internal packaging with low strength and small weight of goods, and can also be used for transportation packaging (outer packaging) for mechanical products and building materials with high strength containers. Second, PVC shrinkable film development prospects and production process shrinkable film first appeared in Germany in the Second World War, the use of PVDC, after bidirectional stretching used to package weapons, to prevent rust. Therefore, the heat shrink film from the beginning of industrial production is used in industrial packaging, and later the heat shrink film is used for food packaging, such as PVDC casings for sausage packaging and so on. PVC heat shrink film is the use of film in the high elastic state of the longitudinal or transverse tension of the energy stored in the film, the use of thermoplastic plastic has a memory effect on the shape of the bidirectional or unidirectional stretch before the memory effect, in the heat can restore the function of the shape before the stretch to achieve the purpose of packaging. PVC heat shrinkable film is a specific application example of the memory effect of a wide range of polymers. PVC heat shrink film production method is the resin particles into the extruder after the use of extrusion blowing film or extrusion salivation method to produce a thick.
