It is an inevitable trend that plastics become the main packaging material.
And its development will greatly exceed other traditional packaging materials.
China's output of cement, fertilizer and building materials ranks first in the world.
And the output of economic pillars such as mineral products and bulk chemical products is also in the forefront of the world.
Both of them have great demand for packaging products, such as composite film and packaging film.
China is also the major producing country of food and fruit in the world, with an annual output of nearly 500 million tons.
There is a wide variety of plastic packaging films.
At present, BOPP packaging film, BOPET film and CPP film are mainly produced and used in large quantities, mainly used for packing textile, food, medicine, tobacco, cosmetics and audio and video products.
Among plastic packaging materials, the market demand for film materials has increased the most, accounting for 46% of the total plastic packaging materials.
The plastic packaging film mainly includes: heat shrinkable packaging film, wrapping packaging film, food aseptic packaging film, fruit and vegetable wrap film, liquid packaging film and etc.
With the continuous improvement of the equipment level of China's plastic film industry, some have reached the advanced level of developed countries, and a number of new products have emerged.
The two-way stretch film, as a composite packaging substrate, not only overcomes the long-term import situation, but now it exports about 300,000 tons and earns more than 3 billion US dollars every year.
The number of large-scale packaging film manufacturing enterprises in China has developed rapidly, and has reached 2240, among which a number of leading enterprises in the industry have emerged, playing a pivotal role in the industry.
The domestic PE protective film industry has made many progress in reducing waste pollution.
With the gradual implementation of domestic environmental protection regulations, this year will make greater progress.
In line with this, its greening has also become one of the important development trends.
There is currently no completely uniform definition of green packaging.
The appropriate packageing which can be recycled or degraded, and does not cause pollution to the human body and the environment throughout the life cycle of the product is called green packaging.
Green environmental protection pe protective film is one of them.
The most important meaning of green packaging is to protect the environment, but also has the significance of resource regeneration.
The use of heat-sealable stretch film plus varnish can significantly reduce the amount of material used, and has been widely used in cold drink and ice cream packaging.
The protective film has successfully reduced the thickness of the entire packaging film by using high-strength metallocene polyolefin.
And the phenomenon of over-packaging is gradually being reduced. The application of co-extrusion compounding technology and equipment is also becoming more and more popular, and the precise thickness control problem of each layer is solved.
The thickness of the expensive barrier layer can be controlled to be very thin, while the preservation performance is doubled or even increased by several tens of times.
China's PE protective film industry has developed rapidly, and it has also strongly promoted the progress of the food, daily chemical and pharmaceutical industries.
The progress of these industries has in turn stimulated market demand.
With the impact of the wave of environmental protection, consumers are placing increasing demands on product packaging.
Green packaging is the need of international environmental protection development trend.
Protective film also represents the development trend of packaging industry in various countries.
It is one of the important contents to improve the market competitiveness of product and avoid new trade barriers.
