New Development Direction of Coating Industry

2020-11-13

At the beginning of this year. Because of the epidemic, people inside and outside the industry are in a state of panic.

 

After March, due to the control of the epidemic situation, demand rebounded rapidly, and confidence recovered quickly. So far, the market demand for coating is basically stable, but due to the supply and demand relationship, the price rise is obvious. However, the supply of pet and BOPP has not increased significantly this year. I think it is mainly due to the increase in demand for solar panels and the increase in the packaging of drugs and masks. Why are the processing costs of pet and BOPP increased significantly? Does the processing cost of aluminum coating not increase? The main reason is that the supply of the above two kinds of films increases little, but the demand increases rapidly. The growth rate of coating equipment is very fast, but the demand is not so fast, so the competition is even greater. Therefore, the processing fee space of the coating industry this year has not increased at all, but the price difference has increased, which is mainly due to the rise of film price. Increased competition behind coating. This is already the case. A few years ago, it was led by European and American countries and promoted by large multinational food companies, cosmetics companies and printing companies. The recyclable and degradable packaging has become a trend in developed countries such as Europe and the United States.

 

This situation has also formed a distinct development trend in China. The recycling of packaging requires the homogeneity of materials. In this way, aluminum foil became the first alternative. The best material to replace aluminum foil must be aluminum coating. However, the barrier property of aluminum foil is very high, and the barrier property of ordinary aluminized film cannot be compared with that of aluminum foil. Therefore, in order to replace aluminum foil, the barrier property of aluminized film must be greatly improved to replace it. Other materials, such as PE, CPP, BOPP and pet, can only be compounded with films of the same material. For example, PE can only be compounded with BOPE. BOPP can only be compounded with CPP, and pet can only be compounded with heat sealing pet.

 

However, these materials generally have a characteristic that the barrier property is not high, which requires that the barrier property of our aluminized film and transparent alumina should be greatly improved.

 

Only when the barrier of alumina and aluminized film is greatly improved, can the homogenization of these materials be carried out smoothly.

 

In addition, the barrier property of degradable materials such as PLA, PVA, etc. is generally not very high. Many packages also need to improve their barrier property. Therefore, if these packages are transparent, many of them need to be coated with alumina. If they are opaque packages, many of them need to be aluminized. Therefore, coating is also a development opportunity for us.

Coating industry in addition to meet the original packaging requirements. Obviously, a new direction of development is to help with biodegradation. Recycling this new development format, coating industry to greatly improve the performance of our transparent and opaque products, is our coating industry challenges, opportunities and new development trend.

 

In addition to the above varieties, there are also some varieties with higher requirements, such as ultra-high barrier, ultra-high adhesion and ultra-thick. There are customers who want to meet one to three performance requirements at the same time.
