DEVELOPING COST EFFECTIVE CO-EXTRUDED FILM STRUCTURES FOR FLEXIBLE PACKAGING

摘要

Co-extrusion enables the combination of attributes of different polymeric resins to create films having unique and tailor-made properties. In this study we show that the proper selection and the correct placement of different polyethylene resins in co-extruded structures enables one to produce films having improved toughness and optical properties in a cost effective way. It was concluded that using single-site linear low density polyethylene in film structures makes this possible.
