The direction of development of plastic materials is to improve performance, reduce costs and contribute to environmental protection. With the development of new plastic varieties and new grades, processing technology and machinery improvements, the performance of materials and packaging products has been improved. This not only reduces material consumption and costs, but also meets people's requirements for the environment.
According to the study report of the European Association of Plastic Manufacturers (APME), the average weight of plastics used for packaging has fallen by 28% over the past ten years, and the amount of use has been reduced by more than 1.8 million tons per year, which has saved resources, among which the plastic packaging film is the most effective and accounts for the savings. More than 70% of Europe's annual packaging material consumption is 66.4 million tons, of which plastic is 11.6 million tons, accounting for 17%, accounting for 50% of the packaged goods, so it can be said that plastics, especially plastics, are the most important to reduce the weight of packaging. In an effective manner, the weight reduction is even greater than the amount of recycled and reused (1.5 million tons per year), which is the most effective for the rational use of resources.
German "Plastics" magazine pointed out that the importance of plastic flexible packaging in food packaging, pointed out that it has become part of the culture, in addition to the role of packaging, it can prevent damage to the package, reduce the requirements for custody, to consumers Provide information to serve customers more effectively, make commodities easier for home management, and easy to store and transport. This can be indicated by the following figures: 30%-50% of food in developing countries is damaged during storage and transportation, while developed in Western Europe The country is currently only 1%-2%. The plastic flexible packaging market has become one of the fastest growing varieties in packaging due to its good overall performance and cost performance ratio.
It can be seen that the average annual growth rate of consumption of plastic flexible packaging is higher and higher than other packaging methods, not only faster than paper packaging, but also higher than plastic hard packaging. The data provided by the famous American Business Communications Corporation (BCC) in the special report of “Change Plastics Flexible Packaging Industryâ€: The total volume of the world's plastic flexible packaging market was only 6.31 million tons in 2001. Currently, the largest amount of food is used for food packaging. 1.68 million tons.
In short, the colorful plastic flexible packaging, with its excellent overall performance, has continuously replaced other packaging, and its use has been expanding. It has become the fastest growing product in the packaging industry at a reasonable price and in favor of the environment. It is expected to remain good in the next few years. The momentum of growth. In order to increase market competitiveness, plastic flexible packaging will develop in the direction of thinning and high performance. The demand for multilayer composite films will increase faster than ordinary single-layer films.
Hot Melt Adhesive For EPE Foam
Pearl cotton, also known as EPE pearl cotton, is a new environmentally friendly packaging material made by heating extrusion foaming process. Compared with traditional packaging, it has the characteristics of thermal insulation, shock and moisture resistance, strong toughness, recyclable and environmental protection.
Pearl cotton needs to use hot melt adhesive for bonding is more choice is also the best effect. Hot melt adhesive is a plastic adhesive which is non-toxic and easy to operate. It is 100% solid at room temperature, and needs to be heated to melt in order to play the bonding role, its viscosity is strong, curing speed is fast, so it is popular, and it is used in pearl cotton bonding, yellowing resistance, cheap price and high cost performance, and it is also environmentally friendly products. And there is no solvent consumption of hot melt adhesive. Therefore, it is very good to avoid the dislocation, shrinkage and deformation easily caused by the solvent, effectively improve product quality and efficiency, and save costs.
The use of hot melt adhesive bonding pearl cotton needs to preheat the melter, and then melt the appropriate amount of colloidal particles, complete the bonding within the opening time of the colloid, and cool and cure after pressing.
