THE MAIN APPLICATION AREAS OF THE CHARACTERISTICS OF PVC HEAT SHRINKABLE FILM

Many things we buy or use in our lives have flexible packaging materials. For example, a circle of promotional pictures on beverage bottles, plastic paper, plastic films on supermarket purchases, transparent bags covered with electronic products, and so on. These things have a common name, called PVC Shrink Printing Film

PVC heat shrinkable film is made of PVC resin mixed with more than ten kinds of auxiliary materials and then inflated twice. It is characterized by good transparency, easy shrinkage, high strength, shrinkage rate can be adjusted freely according to user needs, and strong operability. Its water resistance, flame retardancy, relatively low cost and high output are also favored by manufacturers, sellers and users.

At present, shrink film technology has been developed and can be used to package various commodities. The protective performance of PVC heat shrinkable film packaging: In the production process, the PVC shrinkable film is oriented stretched, and the shrinkable film will shrink during preheating during use. The PVC heat shrinkable film can be made into a cylindrical film or a half-folded film according to customer requirements It can also be processed into curved bags, flat bags, U-shaped bags and other special-shaped bags.

Five-layer co-extruded PVC heat shrinkable film is a new type of packaging substitute product that has gradually emerged and is accepted by people in recent years. The environmentally friendly co-extruded polyolefin PVC heat shrinkable film is a heat shrinkable film with linear low density polyethylene (LLDPE) as the middle layer and co-polypropylene (PP) as the inner and outer layers. It has the characteristics of high transparency, high shrinkage, and good heat sealing performance. It also has the advantages of polyethylene (PE) and polybutene (PP), and its professional performance is far superior to pure polyethylene (PE) and polypropylene (PP) films. PVC heat shrinkable film has been widely used worldwide and has been recognized by the European and American markets.

PVC Shrink Printing Film

Heat shrinkable film is mainly used in the following three areas:

In the beverage packaging field, the total amount of heat-shrinkable film soft drink bottle labeling required by the soft drink packaging, dairy product packaging, and purified water packaging markets exceeds 100,000 tons, and it is increasing at an average annual rate of 18%.

In the field of pharmaceutical packaging, heat shrinkable film is replacing paper boxes, which greatly reduces the packaging costs of pharmaceutical companies. Pharmaceutical packaging mainly refers to bottles, caps, boxes, films, etc. for packaging medicines and medical machinery.

In the field of beer packaging, my country’s beer production exceeded 51.89 million tons last year, and more than 82 billion beer bottles were needed. If 5% uses heat-shrinkable film bottle sleeves, the annual consumption will reach 50,000 tons. The market potential is amazing.

Domestic plastic packaging heat-shrinkable films are used in hundreds of thousands of tons, including PVC, PS, PE and other materials. Among them, PVC is the heat-shrinkable film with the highest market share at present. The development of heat shrinkable technology has promoted the marketization of heat shrinkable films, making PVC heat shrinkable films cover the packaging fields of electronic products, pharmaceutical products and other industries, and promote the development of the product flexible packaging industry. At the same time, heat shrinkable labels and shrinkable bottle caps were also developed.
