Westlake Hifor SC74561-F Clear (Voridian) Polyethylene Film, Using Energx Technology Services (discontinued **)
Categories:	Polymer; Film; Thermoplastic; Polyethylene (PE); Low Density (LDPE); Low Density Polyethylene (LDPE), Molded
Material Notes:	VORIDIAN HIFOR CLEAR SC74558-F polymer is a high strength and high clarity polyethylene designed for blown film extrusion that contains medium slip and low antiblock additives. Films produced with this resin exhibit good toughness, with excellent gloss and clarity for a product of this density. SC74558-F is well suited for packaging frozen goods, fruits and vegetables, and baked goods. Applications/Uses Bakery Film Frozen Food Packaging Blown film Eastman Chemical Company sold its polyethylene business to Westlake Chemical Corporation in Dec. 2006. This grade no longer appears in the Westlake product line.
