EVA lining means that a certain product is put into this EVA box, and then a package is needed outside, and the EVA lining is put into this package. The package can have a metal iron box, or a white cardboard box or carton. 

     EVA lining was first synthesized by the American scientist H.F. Mark in 1928 with a low-pressure method. Later, in 1938, the British ICI Chemical Industry Company published a patent for the manufacture of EVA by a high-pressure polymerization method. In the early 1960s, the American DuPont Company began to have industrial products. .

     From the past to the present, its application products have penetrated into all aspects of people's lives, such as shoe materials, films, wires and cables, toys, hot melt adhesives, coatings and so on.

     EVA lining, as the name suggests, is to put a certain product in this EVA cases, and then need a package outside, put the EVA lining in this package, this package can have a metal iron box, or a white cardboard box or in the carton.

     EVA, it is made of EVA raw materials, color masterbatch, foaming agent, etc. after high temperature foaming. In terms of different foaming, it can be divided into environmentally friendly coarse-pore EVA, ordinary EVA, food-grade odorless environmentally friendly EVA, fire-resistant EVA and anti-static EVA. After processing, EVA sheet can be made into EVA inner support, EVA tray and EVA lining.

     In terms of hardness, there are ordinary EVA linings with a hardness of 38 degrees, a slightly harder 50 degrees, and a hardened 70 degrees. In terms of performance, there are ordinary environmentally friendly EVA linings and fire-resistant EVA linings. Lining and anti-static EVA lining, in terms of color, there are black EVA lining, white EVA lining, and colored EVA lining. In terms of names, some are called EVA inner boxes, EVA trays, etc.

     EVA lining and EVA pallets have been stamped with a knife die to modern computer cutting, punched with a knife die, some are stamped at one time, and some have to be pasted by hand.
