Applications |
|||
| EASTMAN HIFOR Clear SC74550-X polymer is a high strength and high clarity polyethylene designed for blown film extrusion that contains no slip and low antiblock additives. Films produced with this resin exhibit extreme toughness, with excellent gloss and clarity for a product of this density. SC74550-X is well suited for packaging frozen goods, fruits and vegetables, and baked goods. SC74550-X polyethylene complies with FDA regulation 21 CFR 177.1520 (c) 3.2 (a), permitting its use in food packaging applications. Consult the regulations for complete details. | |||
