EPP packaging material is the abbreviation of Expanded Polypropylene, which is a new type of foam plastic. EPP has a low specific gravity, good elasticity, and is resistant to shock and compression. It has a high deformation recovery rate, excellent absorption performance, and is resistant to oil, acids, alkalis, various chemical solvents. It does not absorb water, is insulating, heat-resistant, non-toxic and odorless. It can be recycled 100% with almost no reduction in performance, making it a truly environmentally friendly foam plastic. EPP beads can be molded into various EPP products of different shapes in the molds of a molding machine. EPP packaging is a perfect packaging material processed from chemical raw materials. Through the main molding process technology, polystyrene raw materials are made into packaging products of different shapes. Firstly, the current foam packaging materials are not only white. According to different customer needs, they can also be made into colored packaging materials. Foam packaging is not only light in texture but also has an outstanding shock-proof effect. Although the volume of foam packaging is very large, its weight is very light. Therefore, many entertainment venues use foam packaging to make game castles. Secondly, foam packaging not only has a perfect sound insulation function but also has the highest impact resistance. When the products packaged with foam encounter impacts, it can minimize the damage to the products inside the foam packaging. Foam packaging products are anti-aging and corrosion-resistant. Foam packaging can also withstand many different kinds of chemicals, such as dilute alkalis or dilute acids and other chemical substances. Moreover, the foam packaging used has the characteristic of anti-static, which is especially suitable for packaging various electrical products. EPP has been widely used in the packaging industry, such as for electronic products, medical devices, etc. Especially in the packaging of export products, due to environmental protection requirements, it has become an irreplaceable packaging material. Because it is non-toxic and has high temperature resistance, it is also widely used in food packaging and microwave heating.
