Development of Wuhan Modern Plastic Packaging Industry
In the synthetic tree, 25% is used in the packaging industry. For this reason, the packaging industry is an important sector in the packaging industry. Plastic packaging is one of the four major materials in the packaging industry: paper and cardboard account for 30%, and plastic account for 25%. %, metal accounts for 20%, and glass accounts for 15%. The above two 25% fully illustrate the importance of the plastic packaging industry. Although the plastic packaging industry is now the second-ranked packaging material, its application is not as good as paper and cardboard packaging, but the packaging industry is developing at a rate of 5% every year. Other packaging materials, including paper and cardboard, metal, glass, Ceramics, hemp and cotton, etc. are only growing at a rate of 2%. For this reason, one day the plastic packaging industry will surpass paper and cardboard as the first packaging material. Hollow board production line www.handern.com
In the plastic packaging industry, the continuous development of plastic raw materials, the continuous progress of the molding process and the development of automation are not only different in variety and shape, but also in performance. Packaging materials that can meet high barrier and resistance to various killing conditions have appeared. In the past, high steaming bags were only developed by the US Naval Research Institute for food packaging for aviators (expensive). Since Kou himself successfully developed this convenient and energy-saving plastic packaging material, it has been developing at a high speed of more than 25% every year. It is not only used for packaging of 1kg per bag for personal consumption, but also used for large-scale high-temperature cooking of more than 2kg bags for business use. The shape of the bag has also developed from ordinary three-side-sealed composite bags to stand-up bags, four-body bags and other types. According to statistics, the structure of high-temperature cooking bags has increased from the original two and three layers to more than 100. A variety of different materials and different levels of structure, packaging nearly 1,000 kinds of various foods and dishes can not meet the needs of the people, but also exported from Japan to some countries with similar dietary habits. In 1990, Japan had 40 manufacturers specializing in the production of high-temperature cooking bags, and in 195 it grew to 53. Statistics in 1990: About 50% of curry foods, and about 25% of aquatic products and soups are packaged in high-temperature steaming bags. Hollow board production line www.handern.com
In terms of packaging containers, glass bottles were originally used for packaging beverages, followed by paper composite cans, and then PET bottles. Now rigid PET bottles have become the largest packaging material for carbonated and non-carbon beverages, accounting for 19 years in the United States. 26-5% of beverage packaging containers, glass bottles have dropped from 289% in 1981 to 19.56, aluminum ancient 39% and feed bottles are growing rapidly at an annual growth rate of more than 3%. It can be said that even in countries where the plastic packaging industry suffers the most, such as Italy and other countries, molding materials will continue to develop at a much faster rate than other packaging materials. Many characteristics of plastics are other Any kind of packaging material cannot be replaced. While occupying the sales and packaging collar, the plastic packaging industry has developed into transport packaging, which will eventually force the “transportation packaging”, which is still dominated by metal, to be replaced by plastics.
