At present, plastics have occupied an important position in the field of packaging, all kinds of plastic packaging than other plastic products growth rate, plastic film, woven bags, composite film, sheet and other rapid development in the packaging industry. Although in some special areas, glass packaging is still in the dominant position, light and beautiful plastic flexible packaging to enter the large-scale still need time, but it is also the trend of the times.

Plastic products will dominate the packaging market

The first is the canned 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 technology, flexible packaging cans have also begun to appear sporadically, although the market share is still pitifully small. The shelf life of canned food is generally up to one year, so the outer packaging is required to have a strong barrier. For some foods that need to be sterilized at high temperature, they 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, and explosive bags. In developed countries, plastic flexible packaging cans are favored by consumers for their small packaging, easy to carry, and easy to open. In just a few years, they quickly occupied nearly 30% of the canned packaging market. In the domestic market, cans are still heavy glass bottles and tinplate packaging that are difficult to open, so 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 have a common weakness-they are all hard packaging containers, which requires air to generate pressure during the infusion process to make the liquid drip out, thus greatly increasing the possibility of secondary pollution during the infusion process, especially in hospitals with more bacteria. The soft packaging multi-layer co-extrusion film infusion bag is a better solution to this problem. Pharmaceutical grade polyolefin multi-layer co-extruded film by the multi-layer polyolefin material under clean conditions at the same time melt cross-linking extrusion, the production process does not use adhesives and plasticizers, cylindrical film always maintain a closed state, can avoid pollution. This kind of film material is resistant to high temperature (can be sterilized at 121 ℃), has good light transmittance, good elasticity, anti-drop, and has good barrier property to water vapor, oxygen and nitrogen. It is suitable for filling various electrolyte infusion, nutrition infusion and therapeutic infusion, and does not contain chloride. It does not affect the environment after treatment. It is the development direction of infusion packaging materials.

Then there is the beer packaging. Glass bottles have been used for beer packaging in our country for many years, and bottle explosions occur almost every year. Although cans and barrels are also used in the market, the total amount is not more than 5% at present, and plastic packaging such as PET bottles and flexible packaging arises at the historic moment. Compared with canned packaging, beer packaging requires better freshness and oxygen barrier, and must have a certain pressure capacity. At present, the world is focusing on developing PET plastic bottles as alternative products, but the technology is not yet fully mature., Such as the sealing of the bottle mouth, pressure resistance procedures, anti-penetration and other aspects of the impact on the quality of beer are still being explored, so domestic enterprises are still in the wait-and-see and experimental stage. With the diversification of consumer demand, beer packaging will be closer to consumer demand, tend to be able to effectively maintain stable beer quality, low prices, various forms of packaging products. All kinds of packaging specifications and styles are in demand. For example, bagged beer was widely welcomed in Qingdao as a supporting product for barreled beer not long ago. Customers directly buy plastic bags when buying beer. Therefore, it can be predicted that if the glass bottle is replaced by plastic flexible packaging or PET bottle, it will be easier to meet the different needs of consumers in terms of capacity and shape.

The stability of glass bottles is poor, fragile is not conducive to transportation, and energy consumption is large. Plastic packaging instead of glass packaging is an inevitable trend for the packaging industry to develop in the direction of lightness and durability. Compared with plastic hard packaging, plastic flexible packaging is light, soft, less waste, small space, low cost, and resource saving, so it is more competitive. And composite soft plastic packaging materials with its superior comprehensive performance is the rapid development. At present, China's soft plastic packaging enterprises reached more than 4000, the annual production capacity of domestic composite film has more than 1.5 million tons, composite soft plastic packaging materials has become one of the main domestic more mature packaging materials, has penetrated into all areas of national life. In several major areas of glass packaging, plastic flexible packaging is emerging and will show its skills.
