The origin of heat shrinkable film Release time: 2021-02-18 The materials used for heat shrinkable film are mainly various thermoplastic films. At first, PVC shrink film was mainly used. With the continuous development of market demand, PVC shrink film gradually decreased, and various PE, PP, PET, PVDC, POF and other multi-layer co-extruded heat shrink films developed rapidly and became the mainstream of the market. At present, there are nearly 20 domestic shrink film manufacturers only in the Plastic Packaging Committee of the China Packaging Federation, with an output close to 80,000 tons. Experts predict that the domestic heat shrinkable film market will grow at a rate of more than 20% in the next five years.   The food industry is the largest market for shrink packaging. Heat shrinkable film is widely used in the packaging of various fast foods, lactic acid foods, beverages, snacks, beer cans, various alcohols, agricultural and sideline products, dry foods, and souvenirs. Applications in non-food fields are also increasing, such as labels and bottle caps, seals, fibers and clothing, aerosol products, sporting goods, electrical products, cosmetics, pharmaceuticals, grease, detergents, stationery, toys, office supplies, kitchen supplies , Daily necessities, sundries, building materials, etc. At present, the application of heat-shrinkable film in the domestic market mainly shows the following characteristics:   1) Has been widely used in fast food, ceramic products, tea sets, mechanical parts and other fields;   2) Heat-shrinkable film is used in military machinery and hardware tools. The combination of vapor phase rust prevention technology to replace rust prevention oil is of great significance to enhance the rust prevention ability;    3) Heat shrinkable film is also the protector of construction and transportation materials. It is not only suitable for the packaging of multiple products and packaging with pallets, it is convenient for transportation and sales, easy to realize mechanization, saving labor and material resources, and can partially replace carton and wooden box packaging;   4) Used for various PET bottled beer, Beverage labels can reduce the process of removing labels and facilitate recycling and reuse;   5) Used for bottled beer instead of strapping packaging to prevent bottled beer from exploding and hurting people.   heat shrinkable film selection   customers usually first consider the specific selection mode from the cost. Shrink packaging and laminating film can usually achieve the same packaging effect, so how to decide which packaging film to choose? Generally speaking, the main difference lies in the requirements for packaging patterns, the frequency of packaging, the requirements for shelf life, and the physical properties of the packaging itself such as liquid, powder, granular, solid, square, and so on.   Generally speaking, when choosing a heat-shrinkable package, it is necessary to consider the attractiveness of the package to consumers and good sealing safety. Regarding the heat shrinkable film market and heat shrinkable film applications, there are many corresponding technologies. Looking at the development of the domestic and foreign markets, low temperature heat shrinking technology, low cost technology, multi-purpose adaptability, online packaging technology, and high reliability technology have become The general trend of shrink packaging research. It is precisely because of the continuous promotion of various new technologies that the application fields of heat shrink packaging are becoming wider and wider. Previous: No more
