Flexomer Resins-Another Class of Polyolefins for Film Extrusion

Flexome™ resins represent a new family of polyolefins which exhibit a combination of properties heretofore unavailable. The properties of these resins and some of their blends are given and then compared to more es tablished resins such as linear low density polyethylene (LLDPE), a high pressure produced low density polyethylene (LDPE) and ethylene vinyl acetate copolymers (EVA). It is shown that a good balance of overall toughness, tensile strength and low temperature properties can be obtained, especially when copolymers with high-alpha olefins (HAO) are employed. Selected film fabrica tion effects are reviewed and certain end-uses are suggested based on the prop erty balance obtained with these resins.
