PVC heat shrinkable film is not only used in food, but also in cosmetics. PVC shrink film is very ideal for high cosmetics packaging. Therefore, PVC heat shrinkable film has an indispensable position in our daily life. PVC heat shrinkable film is easy to break during printing. It is not that the quality of the PVC shrinkable film is not good, but that there is a solvent in the special PVC printing ink that will dissolve the PVC film, and this solvent has low volatility. Too much solvent in the solvent of the PVC ink will dissolve the PVC shrink film and be torn off during the printing process. However, if PVC special printing ink is not used, the fastness of printing is not good. PVC heat shrinkable film has the characteristics of good transparency, good toughness, impact resistance, corrosion resistance, and low water vapor transmission rate. When the film is exposed to the corresponding temperature, it will automatically shrink and tightly wrap the goods, thus achieving the function of protecting the goods, and also playing the role of moisture, mildew, rust, pollution, breakage and theft prevention. Good storage and transportation stability, simple packaging technology and equipment, easy to implement automatic shrink packaging. Advantages of PVC shrink film: 1. Wrap the goods stacked on the pallet to make the package more stable and tidy, and waterproof; 2. It has the characteristics of high tensile strength, large elongation, good self-adhesiveness, and high transparency; 3 , Shrink film, heat shrinkable film is mainly mixed and extruded from several different grades of polyolefin resin, which has puncture resistance and high performance; PVC heat shrinkable film is insufficient: for example, some PVC heat shrinkable film is very soft when used in summer , It hardens in winter; some heat shrinkable films are easy to absorb dust and become opaque; some PVC heat shrinkable films have a short service life, are easy to age, cannot withstand wind and frost and sun exposure, and the surface is easy to crack.
