Keyword：PEVA packaging film, PE protective film
The five layer EVOH co extruded film is generally made into a symmetrical structure of PE/Tie/EVOH/Tie/PE. The seven layer co extrusion blown film can be divided into symmetrical structure PE/Tie/PA/EVOH/PA/Tie/PE and asymmetric structure PA/EVOH/PA/Tie/PE/PE/PE.
The barrier performance of EVOH co extruded film is very good, and its oxygen permeability can be less than 1ml, which is nearly a hundred times higher than that of nylon co extruded film. After the COVID-19, the social level has become increasingly strict with the requirements of cold chain food packaging. As a high-performance and barrier packaging material, the domestic market demand has become increasingly strong. At present, it mainly depends on imports from Europe, America, Japan and South Korea. The development of this material has great market potential.
Product targeting the market: suitable for cold chain food packaging such as meat, seafood, cheese, and pharmaceutical packaging.
