Double Layers Blown Film Extrusion

Double Layers Blown Film Extrusion
Double Layers Blown Film Extrusion is employed in the manufacture of plastic laminated films, utilizing materials like low density polyethylene (LDPE), high density polyethylene (HDPE), and linear low density polyethylene (LLDPE). These films find extensive application in packaging for liquids, printed materials, export products, and industrial goods. The use of double-layer co-extrusion laminated film notably enhances the packaging’s durability for liquid preservation.
