PVC Shrink Films are widely used in the packaging industry due to their water resistance, flame retardancy, relatively low cost and high output. However, due to the difficulty in forming the PVC shrink film, it is necessary to add a large amount of plasticizer. Under high temperature and high quality environment, the plasticizer and the vinyl chloride monomer in the heat shrink film will dissolve. Using it directly in contact with food packaging will cause consumption health risks.
PVC shrink film products have the characteristics of non-toxic and environmental protection, high transparency, high shrinkage, good heat sealing performance, high surface gloss, good toughness, high tear resistance, uniform heat shrinkage and suitable for fully automatic high-speed packaging. Used in food, medicine, beverage, alcohol, electrical products, electronic products, toys, and other product packaging. Especially its excellent shrinkage characteristics make it the first choice for collective packaging. Used in food, textile, medicine, packaging of chemical building materials and other products.
PVC Shrink Films
The PVC shrink film is mainly made of ethylene-based PVC resin, combined with more than a dozen kinds of auxiliary materials, and then inflated twice, so the overall product is characterized by very good transparency, and the overall stretch shrinkage is very strong. The use process The quality strength is very high, which certainly guarantees the shrinkage of the product. It can be adjusted according to the user's needs.
Now the use of PVC shrink film can be said to be very popular, widely used in hotel products and food packaging, as well as some common sports equipment, electronics, etc. in daily life, daily necessities, crafts or health products and other drugs will be used Transparent PVC Shrink Wrap Film is used for packaging, which mainly guarantees the beauty of the entire product packaging.
With the gradual development of the packaging industry, heat shrinkable films will be one of the hot spots in the plastics industry in the future. In order to have a place in the market, Multi-purpose Shrink Film Manufacturers have spent their brains, resources, and materials, and competition has become fiercer. This has led to the rapid development of the industry, and plastic films are the largest category of materials. Once most shrink packaging is heated, it will shrink like a PVC shrink film. The short-time hot air effect allows the packaged goods to shrink quickly. Products with irregular shapes are the most practical. The film can shrink according to the shape of the product to be packaged. Therefore, the demand for PVC shrink film in the packaging industry is still very large.
Advantages of PVC shrink film:
1.Wrap the goods stacked on the pallets to make the packaging more stable and tidy, and have a stronger waterproof effect;
2, with high tensile strength, large elongation, good self-adhesion, high transparency and other characteristics;
3. Shrink film, heat shrink film is mainly made by mixing and extruding several different grades of polyolefin resin, with puncture resistance, super strength and high performance.
Through the investigation of well-known enterprises in several industries such as beverages, daily chemicals, pharmaceuticals, and beer, it was found that the biggest reasons for the heat shrink packaging technology to be affirmed are: it can reduce costs, promote sales, and increase shelf display effects.
PVC has good transparency, good oil resistance, good barrier properties to water vapor and oxygen, and good corrosion resistance to many substances such as acids, alkalis, and salts. Using polyvinyl chloride resin and non-toxic additives, plastic packaging that meets national standards and directly contacts packaging beverages, food and pharmaceuticals can be made. However, once the content of vinyl chloride monomer exceeds the standard or inappropriate additives are selected, it may cause safety problems in contact with food during the use of polyvinyl chloride packaging films.
