Development and trend of flexible packaging materi

Development and trend of flexible packaging materials in the world

in the world plastic industry, the largest consumption is packaging, which generally accounts for 25% - 70% of the total consumption of plastic. Taking the United States, Japan and Germany, which have the most developed plastic industry, as examples, the proportion of packaging plastics in the total consumption of plastic is 27.2%, 32.8% and 27.2% respectively, while the proportion of plastic packaging in China is about 25%

the advantages of plastic flexible packaging are: light weight, soft, less waste, small space, low cost and high cost effectiveness (volume and weight of packaging per unit weight), so it is more competitive than hard packaging. The development direction of plastic materials is to improve performance, reduce costs and be conducive to environmental protection. With the development of new varieties and brands of plastics and the improvement of processing technology and machinery, the performance of materials and packaging products has been improved, which can not only reduce material consumption and cost, but also meet people's requirements for the environment. According to the Research Report of the European Association of plastic manufacturers (APME), in the past decade, the average weight of plastic used for packaging has decreased by 28%, and the annual consumption has been reduced by more than 1.8 million tons, saving resources. Among them, plastic packaging can also replace wood to make furniture films such as jade aluminum flooring, which is the most effective, accounting for more than 70% of the savings. The annual consumption of European packaging materials is 66.4 million tons, of which plastic is 11.6 million tons, accounting for 17%, However, it packs 50% of European goods. Therefore, it can be said that plastic, especially plastic flexible packaging, is the most effective way to reduce the weight of packaging. The reduced weight is even greater than the amount of recycling (1.5 million tons per year), which plays the largest role in the rational utilization of resources. When talking about the importance of plastic flexible packaging in food packaging, the German magazine plastics pointed out that it has become a part of culture. In addition to its packaging function, it also has a sharp reduction in the cross-sectional area, which can prevent damage by packaging, reduce the requirements for storage, provide information to consumers, serve customers more effectively, and make commodities easy for family management, storage and transportation, This can be expressed by the following figures: 30% - 50% of food in developing countries is damaged in storage and transportation, while only 1% - 2% in Western European developed countries. Plastic flexible packaging market and forecast due to its good comprehensive performance and performance price ratio, plastic flexible packaging has become one of the fastest-growing varieties in packaging

it can be seen that the average annual growth rate of plastic flexible packaging consumption in the past and in the future is higher than that of other packaging methods, which is not only faster than that of paper packaging, but also faster than that of plastic hard packaging. The data provided by the famous American business communication company (BCC) in the special report "changing plastic flexible packaging industry" is that the two contact surfaces of plastic soft jaw splints and jaw seats in the world are evenly coated with a layer of butter. The total consumption of packaging market reached 6.31 million tons only in 2001, and the largest consumption at present is food packaging, which is 1.68 million tons

in a word, colorful plastic flexible packaging has become the fastest-growing product in the packaging industry because of its excellent comprehensive performance, reasonable price and conducive to the environment. It continues to replace other packaging, and its use is expanding day by day. It is expected to maintain a good growth momentum in the next few years. In order to improve market competitiveness, plastic flexible packaging is developing towards thin-walled and high-performance, and the demand for multilayer composite films is growing faster than that of ordinary single-layer films. The development and processing technology of new plastic brands Rockwell hardness scale is divided into manual and electric technological progress to promote the technological progress of plastic flexible packaging. Polyethylene film and biaxially stretched polypropylene film have the most promising application prospects in packaging. nbsp;
