Concern: China's plastic packaging development
In addition to paying attention to the safety issues of food itself, people are also more than 4.91 million tons of packaging products, 15.5 million tons of glass packaging products, and 1.2 million sets of packaging machinery. This shows the great potential of the packaging industry.
With the emergence of new materials, Fafa will not be eliminated and steadily improve its market position. On April 14, the fifth enlarged meeting of the Fourth Council of the China Film Industry Association, held in Nanchang, Jiangxi, decided to formally implement the registration and filing system for products sold in the film market from May 1 this year, in order to strengthen the film industry in China Integrity system and brand building.
According to reports, the membrane market sales product registration system has an average annual growth rate of 7%. From 2011 to 2015, the total output value is expected to exceed 600 billion yuan, with an average annual growth rate of about 16%. By product classification, China's paper packaging products output can reach 36 million tons in 2015. The thinking has changed. It is developing towards green and environmental protection, exploring more reusable materials, and continually studying and innovating to survive in the gap. The manufacturers stand out and make themselves effective in the fierce competition of all Chinese and foreign companies that produce and sell membrane products in the Chinese market. Initially, they will carry out pilot projects in the field of separation membranes and gradually promote them to the entire functional membrane industry. Its registration and filing include: the enterprise has independent legal personality; the product has the product production standard filed by the national standardization management agency; the product quality is tested by a third-party testing agency authorized by the state or industry; the product has the factory qualified quality test certificate and other conditions. In addition, the China Film Industry Association will recommend excellent film companies and products to the market at an appropriate time on the basis of the registration and filing of film products, and further standardize the market order.
At present, there are more than 200 production enterprises and more than 100 scientific research units in the membrane industry, and there are thousands of membrane engineering enterprises. The development level between the enterprises is quite different, and there is a large gap between the membrane products on the market.
The 2014 functional film industry market and technology held in Shanghai focused on the material safety of food packaging bags. Food safety is of course important, but due to pollution caused by other materials, the damage caused is also very large. In recent years, all kinds of foods on the market have been worried about plastic pollution, such as plasticizers. If the performance stability of the food packaging bag itself is not high, it will easily interact with the food and cause pollution.
The plastic packaging industry maintains 9.46 million tons of plastic packaging products every year. At the Gold Development Seminar, Wu Yaogen, chairman of the BOPP Special Committee of the China Plastics Association and chief engineer of Foshan Fosu Technology Group, published a discussion on the development of new functional film products. The lecture gave a detailed analysis of the development status, existing problems and future development trends of functional films.
Wu Yaogen said that functional films play an important role in strategic emerging industries and have broad application prospects. However, the technical barriers of functional film products are currently high, and there are many problems in raw materials, equipment and processes. "In terms of raw materials, there is a big gap in production." Wu Yaogen said.
Due to the advantages of plastic itself, functional films such as high-impedance separators, electrical insulating films, battery separators, optical films, photovoltaic solar cell packaging films, etc. will be used in the future.
Secondly, the lightweight technology is still mainly imported, and special polyester film currently plays an indispensable role in aerospace, biotechnology and urban transportation. In the "12th Five-Year" Development Guidance of Plastic Processing Industry Technology Progress recently released by the China Plastics Association, films with special functions generally require special grades of resin products, such as polypropylene resins required for BOPP packaging films, and domestic BOPP special materials. It can be used to produce ordinary optical films, and the raw materials for producing high-performance films are mainly controlled by the United States, Japan, and South Korea. The domestic polyester film industry lacks advanced process technology, resulting in a single film product, which is mostly limited to low-end In the market, domestic and international opinions on process technology, interest and international companies monopolize; in terms of equipment, the processing accuracy, stretching speed and process parameter control of domestic equipment have a large gap with foreign equipment, so the film design The functionality of strong plastics can meet the various urgent needs of the national economy and downstream industries. During the "Twelfth Five-Year Plan" period, emerging industries such as energy conservation and environmental protection, new energy, high-end equipment manufacturing and biotechnology have put forward higher requirements for the performance of the supporting plastics. For example, each clearly pointed out that the development direction of the plastic processing industry is function Chemical, lightweight and micro-molding. Wu Yaogen believes that this also applies to the functional film industry.
First, energy increase and emission reduction provide support. Traditional materials and processes can no longer meet the requirements of the low-carbon economy era. The new environmentally friendly, lightweight and high-strength materials processing technology and molding process make it possible to further reduce the weight of plastic films.
Finally, micro-molding technology integrates the most cutting-edge technology from equipment to molding process, including 3D printing, micro-injection molding, stacking molding, etc., which will expand the application of plastic films on high-precision end parts to meet the miniaturization of plastic parts. demand.
