At present, plastics have occupied an important position in the packaging field. All kinds of plastic packaging have surpassed the growth rate of other plastic products. Plastic films, woven bags, composite films and sheets have developed rapidly in the packaging industry. Although glass packaging is still in the main position in some special fields, it will take time for the light and beautiful plastic flexible packaging to enter on a large scale, but it is also the trend of the times.
First of all, the canning market, domestic glass bottles and metal cans still firmly occupy the dominance, but in recent years, with the development of flexible packaging materials and processes, canned soft packaging has begun to appear sporadically, although the market share is still very poor. The shelf life of cans is generally up to one year, so it is required to have a strong barrier to outsourcing. For some foods that need to be sterilized by high temperature, they must have good high temperature resistance. Then there is a high transparency like glass, so that consumers can see the product directly. At present, domestic products generally have problems such as short shelf life, poor toughness, and explosive bags. In developed countries, plastic soft-pack cans are favored by consumers because of 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, canned food is mainly based on bulky glass bottles and tinplates that are difficult to open, so plastic packaging will have good market development potential.
Followed by the infusion bottle market in China. After several decades of application, glass infusion bottles have quickly abdicated to plastic infusion bottles, but they have a common weakness -- they are hard-packed containers, which require the introduction of air in the infusion process to generate pressure. Dropping, which greatly increases the possibility of secondary pollution in the infusion process, especially in hospitals with more bacteria. The flexible packaging multi-layer co-extruded film infusion bag better solves this problem. The pharmaceutical grade polyolefin multi-layer co-extruded film is simultaneously melt-crosslinked and extruded by a multi-layer polyolefin material under clean conditions. The binder and the plasticizer are not used in the production process, and the tubular film is always kept in a sealed state. Avoid pollution. The membrane is resistant to high temperature (can be sterilized at 121 ° C), has good light transmission, good elasticity, and is resistant to falling. It has good barrier to water vapor, oxygen and nitrogen, and is suitable for filling various electrolyte infusions, nutrient infusions and Therapeutic infusion, and does not contain chloride, does not affect the environment after treatment, and is the direction of the development of infusion packaging materials.
Then there is the beer packaging. China's beer packaging has been using glass bottles for many years. The explosion of bottles has occurred almost every year. Although there are also cans and cans in the market, the current total does not exceed 5%. PET bottles, flexible packaging and other plastic packaging will emerge. . Compared with canned packaging, beer packaging requires better freshness and oxygen barrier properties, and has a certain pressure bearing capacity. At present, PET plastic bottles are being developed as substitutes in the world, but the technology is not yet fully mature. For example, the degree of influence on the quality of beer, such as the sealing property of the bottle mouth, the pressure resistance program, and the anti-penetration, 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 the needs of consumers, and tend to be able to effectively maintain a stable quality of beer, low prices, and a variety of packaging products. Various packaging specifications and styles are required. For example, in the near future, bagged beer as a supporting product for barreled beer has been widely welcomed in Qingdao. Customers buy plastic bags directly when they buy beer. It can be foreseen that if plastic bottles or PET bottles are used instead of glass bottles, it will be easier to meet the different needs of consumers in terms of capacity and shape.
The stability of the glass bottle is poor, the fragility is not conducive to transportation, and the energy consumption is large. The replacement of the glass packaging by the plastic packaging is an inevitable trend of the packaging industry to develop in a light and durable direction. Compared with plastic rigid packaging, plastic flexible packaging is more competitive, lighter, softer, less waste, smaller footprint, lower cost, and resource saving. The composite soft plastic packaging material is rapidly developing with its superior comprehensive performance. At present, there are more than 4,000 soft plastic packaging enterprises in China, and the annual production capacity of domestic composite membranes has exceeded 1.5 million tons. Composite soft plastic packaging materials have become one of the more mature main packaging materials in China, and have penetrated into various fields of national life. In the field of several glass packaging dominated the world, plastic flexible packaging is emerging and will show its talents.
