Product Description
LLDPE Injection Molding(MFI 50) for food containers, housewares and lids
Ultra-high flow LLDPE MFI 50 injection grade engineered as a low viscosity LLDPE for molding complex intricate mold resin components. This high flow polyethylene delivers exceptional fill performance in micro-thin walls and fine details, making it an ideal medical device resin for disposable syringes, IV connectors, and surgical housings requiring precision, clarity, and biocompatibility.
