Brief introduction of PVC heat shrinkable film

Brief introduction of PVC heat shrinkable film Release time: 2019-12-13 　　 PVC heat shrinkable film can play a close-fitting, firm, waterproof, moisture-proof, dust-proof and beautiful effect on the single packaging of the packaged material or the collective packaging of groups. The product can be processed It can be made into PVC single split film, roll film, tube film, heat shrinkable bag, tube material cut and shrink label of various specifications, shrinkable rubber cap, etc. PVC heat shrinkable film can be widely used in food, beverage, medicine, health care products, stationery, Outsourcing of books, cosmetics, handicrafts, toys, electronic products, etc.　　Shrink film storage method: strictly forbid direct sunlight, keep in a cool place!　　PVC heat shrinkable film bag is the most commonly used heat shrinkable material in heat seal packaging. Through hot air blowing, the high-transparency heat-shrinkable film can be close to the surface of the article, so as to improve the product grade, prevent dust and moisture, and let the article show a new and perfect packaging effect. Heat shrinkable film packaging, the operation method is simple and easy to learn.　　 heat shrinkable film is used for the sales and transportation of various products, and its main function is to stabilize, cover and protect the products. The heat shrinkable film must have high puncture resistance, good shrinkage and certain shrinkage stress. PVC shrink film is widely used in wine, food, sports goods, sterilized tableware, electronic appliances, daily necessities, handicrafts, maintenance products, audio-visual products, medicines, stationery, toys, portals, plastic hardware, glass ceramics and other commodities The packaging makes the appearance more distinctive and beautiful, improves the packaging grade of the product, and protects the product from dust and squandering. It is currently an ideal film packaging material.　　PVC shrink film, additional ingredients are added to enhance its heat resistance, toughness, ductility, etc. The top layer of this surface film is lacquer, the main component in the middle is polyvinyl chloride, and the bottom layer is back-coated adhesive. It is a kind of synthetic material that is well-loved, popular and widely used in the world today. Among the materials that can produce three-dimensional surface films, PVC is the most suitable material. Reduce atmospheric pollution: As the thickness of the pre-stretched stretch film is significantly thinner, the amount of use in packaging the same goods is also significantly reduced, resulting in a reduction in the total transportation volume, thereby reducing transportation energy consumption and exhaust emissions, and reducing the impact on the atmosphere. Environmental pollution.　　Reduce the amount of waste to be processed Packaging the same goods, the amount of pre-stretched stretch film is significantly reduced, so the post-use recycling treatment of stretch film is also reduced by about 50%.　　Recycling: Green and environmentally friendly stretch film, using general recycling equipment in the factory can be 100% recycled and granulated. It can not only reduce environmental pollution, but also save the cost of recycling packaging.　　Reduce the overall packaging cost: replacing the traditional stretch film with green environmental protection film, the total amount of use is significantly reduced, so its use cost, transportation cost and storage space cost are all reduced.　　Easy to use and high work efficiency: As the green and environmentally friendly stretch film is processed with pre-stretching technology, it is quite labor-saving to use, and there is no special packaging machine and special packaging site, which can be operated by men, women and children. Under the same weight, the length of each roll of this green environmental protection stretch film is more than twice that of ordinary stretch film. It can reduce the frequency of changing the film roll when packaging, and in terms of transportation, packaging and distribution It can also save costs. Due to the unique properties of PVC (rain-proof, fire-resistant, anti-static, easy to shape) and low-input and high-output characteristics of PVC, it is widely used in the building materials industry and packaging industry. Therefore, PVC film has high transparency, good gloss and shrinkage. Features such as high rate.
