PE/regrind/tie/EVOH 4 layers cosmetic bottle blow molding machine on the show

This video shows our PE/regrind/tie/EVOH 4 Layers cosmetic bottle blow molding machine on the show. EVOH stands for Ethylene-vinyl alcohol copolymer and is a flexible, crystal clear, glossy thermoplastic copolymer. This material has excellent flex-crack resistance, and exhibits a high resistance to hydrocarbons, oils and organic solvents. EVOH is known for having some of the best barrier resistance to gases such as oxygen, nitrogen, and carbon dioxide which makes it particularly suited for packaging food, drugs, cosmetics, and other perishable products. When compared to other common films, EVOH is considered to have superior barrier properties. However, when exposed to moisture, EVOH loses its good gas barrier properties. For this reason, EVOH is often used in a multilayer co-extruded film structure with materials such as HDPE, PP and PET, all of which have superior moisture barrier properties. Through the process of extrusion lamination, a pre-made EVOH film is wound around a heated chrome roll, fe
