Double Layers Blown Film Extrusion

Double Layers Blown Film Extrusion
The technique of double layer blown film extrusion is employed to create laminated plastic films from various materials, including low density polyethylene (LDPE), high density polyethylene (HDPE), and linear low density polyethylene (LLDPE). These films find extensive application in the packaging of liquids, printed materials, export items, and industrial products. The implementation of double layer co-extrusion for laminated films greatly enhances the strength and longevity of packaging for liquids.
