The domestic plastic easy to tear composite film has a broad prospect. The coming of the green era, plastic film has a wide range of applications in agriculture, industry, architecture and other fields due to its large output and wide variety. At present, the output of plastic film in China accounts for about 20% of the total output of plastic products, which is one of the categories of plastic products with rapid output growth. In the next few years, the demand for plastic film in the domestic market will continue to grow at a rate of 9%. The market prospect of plastic film in China is very broad.

At present, about two-thirds of China's plastic film consumption is used as packaging materials, agricultural plastic film accounts for about 30%, and the rest is used as electrical materials, light-sensitive materials and electronic information materials.

China is the country with the largest production and use of agricultural plastic film. Agricultural plastic film is mainly a modern agricultural covering material, such as shed film and mulch film, forage film, sunshade net, insect proof net, etc. At present, the annual use of various greenhouse films in China is about 1.5 million tons, and the annual renewal demand is about 700000 tons. The films used are ordinary PVC film, PVC drip free film, ordinary polyethylene film, polyethylene drip free film, polyethylene multi-function composite film and EVA multi-function composite film. The plastic film coverage area in China has increased by about 10 million mu per year on average. At present, the plastic film coverage area has reached more than 200 million mu, and the actual consumption of plastic film is about 450000 tons per year, ranking first in the world.

With the rapid development of agricultural science and technology, the demand for mulching film will continue to grow. China's plastic film industry is facing significant development opportunities. Enterprises should increase technology investment, make rational use of resources, and make up for deficiencies in production technology and material supply as soon as possible, so as to win more market shares in the plastic film market.

At present, the greening of plastic flexible packaging film has also become one of the important development trends. Although there is no completely unified definition of green packaging at present, generally speaking, the appropriate packaging that can be recycled, recycled or degraded, and does not cause public hazards to human beings and the environment throughout the life cycle of the product is called green packaging.

The most important meaning of green packaging is to protect the environment, but also has the significance of resource regeneration. During the whole life cycle of green packaging, it follows the economic activity behavior principle of "reduction, reuse and resource" of circular economy to minimize the impact of packaging on the environment. In recent years, continuous progress has been made in the recycling and reuse of plastic wastes, and the problem of secondary pollution has been gradually solved. It is expected that the future development prospects will be broader.
