Many things we buy or use in our lives have flexible packaging materials. For example, beverage bottles, plastic paper, promotional picture circles for purchasing plastic films in supermarkets, transparent bags covering electronic products, etc. These things have a common name, called PVC Heat Shrinkable Film.
PVC heat shrinkable film is made of PVC resin mixed with more than ten kinds of auxiliary materials and then inflated twice. Good transparency, high easy shrinkage rate, high strength, shrinkage rate can be adjusted freely according to user needs, strong operability. Its water resistance, flame retardant, low cost and high output are also favored by manufacturers, sellers and users.
Heat Shrinkable Film
At present, the annual demand for Heat Shrinkable Film in my country's beverage, cosmetics, and pharmaceutical industries is about 1 million tons, and the market is unprecedentedly broad.
In China, shrink film is mainly used in the following three areas:
In the field of beverage packaging, the total amount of heat-shrinkable film soft drink bottle labels required by the soft drink packaging, dairy product packaging, and purified water packaging markets exceeds 100,000 tons, and is growing at an average annual rate of 18%.

At present, the number of plastic packaging heat shrinkable films in my country is hundreds of thousands of tons, including materials such as PVC, PS, and PE. Among them, PVC Film is the heat shrinkable film with the highest market share.
The development of heat shrinkable technology has promoted the marketization of heat shrinkable film, so that PVC heat shrinkable film covers the packaging fields of electronic products, pharmaceutical products and other industries, and promotes the development of product flexible packaging industry. At the same time, heat shrinkable labels and heat shrinkable bottle caps were also developed.
