What Are the Main Application Areas of PVC Heat Shrinkable Film?

May. 07, 2020

At present, Shrink Films technology has been developed and can be used to package various commodities. Protective performance of PVC heat shrinkable film packaging: During the production process, the PVC shrinkable film is directionally stretched. During use, the shrinkable film will shrink during preheating. The PVC heat shrinkable film can be made into a tubular film or a folded film according to customer requirements. And the single film can also be processed into curved bags, flat bags, U-shaped bags, and other special-shaped bags.

Many things we buy or use in life have flexible packaging materials. For example, a circle of plastic paper on a beverage bottle, plastic film on items purchased in supermarkets, transparent bags covered with electronic products, etc. These things have a common name, called PVC Heat Shrinkable Films.

PVC Heat Shrinkable Film is made of PVC resin mixed with dozens of auxiliary materials and then inflated twice. It is characterized by good transparency, easy shrinkage, high strength, shrinkage rate can be freely adjusted according to user needs, and strong operability. Its waterproof, flame retardant, relatively low cost and high output characteristics are also favored by manufacturers, distributors, and users. At present, the annual demand for heat shrinkable film in the four industries of China's beverage, cosmetics and pharmaceuticals are about more than 1 million tons, which shows that its market is unprecedentedly broad.

In China, the heat-shrinkable film is mainly used in the following three fields. In the beverage packaging field, the total amount of heat shrinkable film soft drink bottle labeling required for 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%.

In the field of pharmaceutical packaging, heat-shrinkable films are replacing cartons, which has greatly reduced the packaging costs of pharmaceutical companies. Pharmaceutical packaging mainly refers to bottles, caps, boxes, films, etc. used for packaging medicines and medical machinery.

In the field of beer packaging, China ’s beer output exceeded 51.89 million tons last year, requiring more than 82 billion beer bottles. If 5% of adopts heat-shrinkable film bottle covers, the annual consumption will reach 50,000 tons and the market potential is very amazing. At present, there are hundreds of thousands of tons of plastic packaging heat-shrinkable film in China, including PVC, PS, PE, and other materials, of which PVC is the heat-shrinkable film with the highest market share. The development of heat shrinkable technology has promoted the marketization of heat shrinkable film, which makes PVC heat shrinkable film covers the packaging field of electronic products, pharmaceutical products, and other industries and promotes the development of the product's flexible packaging industry. At the same time, shrinkable heat labels and shrinkable bottle caps were also developed.
