Many of the things we buy or use in life have soft packaging materials. For example, there is a circle of plastic paper on a beverage bottle, plastic film on goods purchased from supermarkets, transparent bags covered by electronic products and so on. All these things have a common name, called PVC plastic film.

The PVC plastic seal membrane is made up of two times after mixing with PVC resin and more than ten kinds of excipients. Its characteristics are good transparency, easy shrinkage, high strength and shrinkage rate. It can be adjusted freely according to the needs of users, and it has strong operability. Its waterproofing, flame retardancy, relatively low cost and high output are also favored by the production enterprises, sellers and use enterprises.

At present, the annual demand of the 4 industries in China's beverages, cosmetics and drugs is about about 1000000 tons, which shows that the market is unprecedented.

In China, the plastic film is mainly used in the following three fields.

In the field of beverage packaging, the total amount of plastic film and soft drink bottle label used in soft drink packaging, dairy products packaging and pure water packaging market is more than 100 thousand tons, and it is increasing at an average annual rate of 18%.

In the field of medical packaging, plastic envelope is replacing cartons greatly reducing the cost of packaging for pharmaceutical enterprises. Medical packaging mainly refers to the bottle, cover, box, film and so on for the packaging and medical machinery.

In the field of beer packaging, China's beer output exceeded 51 million 890 thousand tons last year, which required about about 82000000000 bottles of beer bottles. For example, if 5% uses plastic film bottle sets, the annual consumption will reach 50 thousand tons, and the market potential is amazing.

At present, there are one hundred thousand tons of plastic packaging film in China, including PVC, PS, PE and other materials, of which PVC is the highest plastic seal film in the market.

The development of thermal shrinkage technology promotes the marketization of plastic seal film, making the PVC plastic film cover the packaging fields of electronics, pharmaceutical products and other industries, and promotes the development of the product flexible packaging industry. At the same time, the heat shrinkable label and the shrinking bottle cap are also developed.
