Development status of China's flexible packaging The domestic flexible packaging industry has a history of more than 20 years. For more than 20 years, the domestic flexible packaging industry has grown from small to large and has developed rapidly. Now it has reached a relatively mature stage, showing a clear trend of grouping and scale.
As the most promising packaging market, China will naturally attract foreign investment. This is both an opportunity and a challenge for China's flexible packaging and color printing companies. At present, there are about 400 imported gravure soft packaging production lines and nearly 1,000 domestic wide-format high-speed gravure flexible packaging production lines on the mainland of China. The production level of these production lines has approached or reached the level of developed countries. World-class printing companies are accelerating their development in China by means of absolute control, the establishment of new wholly-owned production companies and holding companies, and mergers and acquisitions of China's advantageous enterprises. Domestic flexible packaging and color printing companies are aware of the crisis and huge opportunities, and have also adopted various methods to expand the scale of the industry and to develop the industry in the field of marginalization.
Faced with Technical Barriers Although China's flexible packaging has been developed for more than 20 years, it still has a wide disparity with foreign countries. It is mainly reflected in the backwardness of technical equipment, the large number of machines that need to be imported, and raw materials that cannot be produced independently.
(1) From the point of view of soft plastic packaging production equipment, China's soft plastic packaging production equipment starts with imitation imported equipment. As the quality of steel, machining accuracy and heat treatment and other comprehensive technologies can not keep up with the world level, the overall machinery The equipment quality is not high and the degree of automation is still low. Therefore, many flexible packaging equipments are still imported today.
This fully shows that China's equipment manufacturing industry is backward. With regard to flexible packaging printing equipment, although there are currently 1 to 2 printing machinery factories in China capable of producing fully automatic computer-to-print high-speed gravure printing, some of the key components still need to be imported from Japan, and there is still a certain gap in quality. This is why so far people have to buy foreign presses in order to expand their production to spend 3 to 5 times more than domestic prices. There is a gap between the vacuum aluminum plating equipment and the co-extrusion compounding unit, and all the five or more composite die heads in the co-extrusion compounding machine are imported.
(2) As for raw and auxiliary materials, China cannot currently produce blown-film nylon resin. Biaxially-stretched nylon film is processed and molded by foreign resins and equipment. The company is only produced by Foshan East Packaging Materials Co., Ltd. Imported abroad. The adhesive resin (Tires) used in co-extrusion compounding has not yet been manufactured in China. Although the research unit is engaged in research and development, it has not been successful. K coating and PVDC resin (blow film) materials, eval, PAN, etc., have no domestic particle supply yet, relying on imports. Even Surlyn, MPE particles are imported. For this reason, the output of China's resin can not only meet the needs of the domestic processing industry, it must import more than 5 million tons each year, and the type and brand of resin are even more absent. For example, EVA particles with a high VA content for block copolymers for high-temperature cooking, and peelable heat-sealing PE brands with a low heat-seal temperature are required to be imported.
(3) The quality of soft plastic packaging products (bags), internal performance and appearance of printing have a certain gap compared with foreign countries. For example, the shelf life of high-temperature cooking bags is now 6 months for domestic manufacturers, and transparent for more than one year in foreign countries and opaque for more than two years. The products are of the same type, and generally only have three-side sealed pockets. The foreign packaging forms are various, including stand-up bags, pleated bags, pillow-type, kink, and PTP medical packaging. At present, the use of microwave heating in foreign countries has become popular. We should also consider this new packaging structure.
Convenient environmental protection is the development trend At present, the overall development level of China's soft packaging industry is higher than that of Russia and other Eastern European countries, and is also higher than other Asian countries except Japan and South Korea. The level of development of the flexible packaging industry with South Korea and Taiwan Province of China is basically the same. The main gap between the flexible packaging industry and the developed countries is reflected in the product standards as well as the medium and high-end modern packaging materials, especially in the development and production of special and special functional packaging materials.
With the development of people's industries and the deteriorating environmental destruction, environmental protection has become a concern for everyone. As a source of pollution, industrial manufacturing must transform and upgrade in order to survive for a long time. The development trend of the packaging industry is still environmental protection packaging.
1. Recovery of flexible packaging Through pyrolysis, the carbonized residue formed by plastics containing inorganic materials will contain 80% of liquid carbon and 20% of gaseous carbon (due to the lack of oxygen in the chamber, CO2 gas will not be produced). Depending on the liquid fuel/energy requirements, these carbons can be delivered to different locations. The resulting ash can be used as a component of products such as concrete premixes. Whereas carbon can be used as a fuel, companies often import mixed waste into the pyrolysis chamber, producing fuel that may not have the best possible availability.
An effective way to transform this liquid carbon fuel into more durable, high-integrity energy requires continuous research.
Finding a more effective waste disposal process in flexible packaging and having a lower impact on the environment is a challenging task, but it is possible. With the innovations already made in the flexible packaging industry, such as the use of bio-based materials or the conversion of waste into energy for the pyrolysis process, the foundation for further development has been laid.
2. New Trends in High-Performance Packaging Bags Opening Up a New Phase of the Market Some mature markets have begun to embrace and popularize higher-performance bags, such as the United States, Canada, Western Europe, and Japan, which also support dollar conversion in transactions. In the forecast of development prospects, stand-up bags will have the greatest potential for growth. Although flat bags will continue to occupy the vast majority of market share, people are gradually tending to this kind of three-dimensional packaging, especially in the mature packaging market mentioned above.
The aesthetic taste of consumers, and the self-appreciation of stand-up packaging, such as the convenience and stability of standing and packaging at the mouth and the mouth, make consumers have consumer preferences. At the same time, lightweighting is also a trend in the development of plastic packaging bags. The reduction of consumables and the light load of transportation have reduced the cost, which is in line with the interests of producers. At the same time, for the market, lightweight packaging bags also bring new environmental protection and convenience of consumer trends, is gradually being respected.
Cnc Machinery
CNC machinery is widely viewed as a hands on craft that employs the use of many types of saws, drills, and Cnc Routers and more but the use of CNC technology has made it possible to have all these jobs completed with great speed and precision, CNC Routers has wood cutting machine function,cnc machine milling function and cnc machinery engraving function. The quality and repeatability of the cuts that can be achieved using a CNC Routers is hard to ignore. Intricate wood carvings have long been a standard that has set custom jobs apart from others.
