The hottest plastic products will dominate the pac

Plastic products will dominate the packaging market

at present, plastic has occupied an important position in the packaging field, and all kinds of plastic packaging have exceeded the growth rate of other plastic products. Plastic films, woven bags, composite films, sheets and so on have developed rapidly in the packaging industry. Although in some special fields, glass packaging is still in the dominant position, and it will take time for lightweight and beautiful plastic flexible packaging to enter on a large scale, it is also a general trend

first of all, the can packaging market, domestic glass bottles and metal cans still firmly occupy the dominant position, but in recent years, with the development of flexible packaging materials and processes, flexible packaging cans also began to appear sporadically, although the market share is still very small. The shelf life of canned food is generally one year, so the outer packaging is required. We can see that the mechanical properties of the resin have been greatly increased, with strong barrier. For some foods that need high-temperature sterilization, they should also have good high-temperature resistance. Another is to have the same high transparency as glass, so that consumers can directly see the product. At present, domestic products generally have problems such as short shelf life, poor toughness, explosive bags and so on. In developed countries, plastic cans with flexible packaging are favored by consumers because of their small packaging, easy to carry and easy to open. In just a few years, they have quickly occupied nearly 30% of the canned packaging market. In the domestic market, cans are mainly packed in bulky glass bottles and tinplate that are difficult to open. Therefore, small plastic packaging will have good market development potential

the second is the infusion bottle Market in China. After decades of application, glass infusion bottles have rapidly abdicated to plastic infusion bottles, but they all have a common weakness - they are hard packed containers, which requires introducing air to generate pressure during the infusion process to make the medicine drip out, thus greatly increasing the possibility of secondary pollution in the infusion process, especially in hospitals with more miscellaneous bacteria. The soft packaging multi-layer coextrusion film infusion bag can better solve this problem. Pharmaceutical grade polyolefin multi-layer coextrusion film is produced by multi-layer polymerization, which reduces the innovation cost and risk. Olefin materials are fused and cross-linked at the same time under clean conditions. Adhesives and plasticizers are not used in the production process. The cylindrical film is always kept in a closed state, which can avoid pollution. This kind of membrane material has high temperature resistance (can be sterilized at 121 ℃), good light transmittance, good elasticity, fall resistance, and good barrier to water vapor, oxygen and nitrogen. It is suitable for filling all kinds of electrolyte infusion, nutritional infusion and therapeutic infusion, and does not contain chloride. It does not affect the environment during post-treatment. It is the development direction of infusion packaging materials

another is beer packaging. Glass bottles have been used in beer packaging in China for many years, and bottle explosion events occur almost every year. Although cans and barrels are also used in the market, the total amount is no more than 5%. Plastic packaging such as PET bottles and flexible packaging came into being. Compared with canned packaging, beer packaging requires better freshness preservation and oxygen barrier, as well as a certain pressure bearing capacity. At present, the world is focusing on developing pet plastic bottles as alternative products, but at present, due to the fact that the technology is not yet fully mature, such as the tightness of the bottle mouth, pressure procedures, anti penetration and other aspects of the impact on beer quality is still being explored, so domestic enterprises are still in the wait-and-see and experimental stage. With the diversification of consumer demand, beer will explore the qdlp (qualified domestic limited partner) model of venture capital market. Wine packaging will be closer to consumer demand, and will tend to be packaging products that can effectively maintain stable beer quality, low price and diverse forms. Various packaging specifications and styles are in demand. For example, bagged beer, as a supporting product of barreled beer, began to be widely welcomed in Qingdao not long ago. When customers buy beer, they directly choose plastic bags for packaging. It can be predicted that if plastic flexible packaging or PET bottles are used to replace glass bottles, it will be easier to meet the different needs of consumers in terms of capacity and shape

glass bottles have poor stability, are fragile, are not conducive to transportation, and consume a lot of energy. Plastic packaging instead of glass packaging is an inevitable trend for the packaging industry to develop towards lightness and durability. Compared with plastic hard packaging, plastic soft packaging is lighter, softer, less waste, takes up less space, costs less, and saves resources, so it is more competitive. The composite flexible plastic packaging materials are developing rapidly because of their superior comprehensive properties. At present, there are more than 4000 flexible plastic packaging enterprises in China, and the annual production capacity of domestic composite film has exceeded 1.5 million tons. Composite flexible plastic packaging materials have become one of the more mature main packaging materials in China, and have penetrated into all fields of national life. In the field of several glass packaging dominating the world, plastic flexible packaging is emerging. Check whether the amplifier unit is normal and will play a big role
