Eva foaming is very common in life, and it is widely used in the production of product packaging materials and some mechanical products, such as meters, cold storage insulation materials, tableware jewelry gift boxes and so on. And it is common in all aspects of life. Eva foam is very light in weight, does not contain any metal substances, and will not rust off porcelain when exposed to the sun frequently, so it is very suitable for daily use.
