At present, plastics have occupied an important position in the packaging field. All types of plastic packaging have exceeded 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 dominant position in some special areas, it will take time for light and beautiful plastic flexible packaging to enter on a large scale, but it is also a general trend.
First of all, the canned packaging 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, soft cans began to appear sporadically, despite the market share is still very poor. The shelf life of cans is generally up to one year, and therefore requires a strong barrier property. For some foods that are to be sterilized at high temperatures, they must have good high temperature resistance. Then there is the same high transparency as glass so that consumers can see the product directly. Domestic products currently have problems such as short shelf life, poor resilience, and explosive bags. In developed countries, plastic flexible packaging cans are favored by consumers because of their small package, easy portability, and easy opening. They have quickly occupied nearly 30% of the canned packaging market in just a few years. In the domestic market, canned foods are mainly based on bulky glass bottles and tinplates that are difficult to open. Therefore, small plastic packaging will have a good market potential.
Followed by China's infusion bottle market. After several decades of application, glass infusion bottles have rapidly retired to plastic infusion bottles, but they have a common weak point -- they are all hard-packed containers. This requires the introduction of air pressure during the infusion process. Dripping, which greatly increases the possibility of secondary contamination during infusion, especially in the case of more bacteria. The flexible packaging multilayer co-extruded film infusion bag is a good solution to this problem. Pharmaceutical grade polyolefin multi-layer co-extruded films are simultaneously melt-crosslinked and extruded from multilayer polyolefin materials under clean conditions. No adhesives and plasticizers are used in the production process, and the cylindrical film is always kept in a closed state. Avoid pollution. The membrane material is resistant to high temperatures (sterile at 121°C), good light transmission, good elasticity, resistance to falling, good barrier to water vapor, oxygen and nitrogen, suitable for filling various electrolyte infusions, nutrient infusions and Therapeutic infusions, which do not contain chlorides, do not affect the environment during post-treatment and are the direction of infusion packaging materials development.
Then there is beer packaging. China's beer packaging has been used for many years as glass bottles. Bumping events occur almost every year. Although there are also canned and canned bottles on the market, the total amount does not exceed 5% at present. PET bottles, flexible packaging and other plastic packaging have emerged . Compared with canned packaging, beer packaging requires better preservation and oxygen barrier properties, and has certain pressure-bearing capacity. At present, the world is focusing on the development of PET plastic bottles as an alternative product, but currently the technology is not yet fully matured. For example, the degree of influence on the quality of beer, such as the sealability of the bottle mouth, pressure resistance procedures, and penetration prevention, is still being explored. Therefore, domestic enterprises are still waiting to see and experiment. With the diversification of consumer demand, beer packaging will be closer to consumer demand and tend to be able to effectively maintain a stable, low-cost, and diverse packaging product. There are demands for various packaging specifications and styles. For example, bagged beer was recently welcomed as a matching product for bottled beer 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 poor stability of glass bottles, fragile is not conducive to transport, energy consumption, plastic packaging alternative glass packaging is the inevitable trend of the packaging industry to light, durable direction. Compared with plastic hard packaging, plastic flexible packaging is lighter, softer, less wasteful, takes up less space, has lower cost, and saves resources, and is therefore more competitive. 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 companies 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 most mature domestic packaging materials and have penetrated into various fields of national life. In the field where several big glass packaging dominates the world, plastic flexible packaging is emerging and will show itself.
