Categories: Polymer; Film; Thermoplastic; Polyethylene (PE); HDPE; High Density Polyethylene (HDPE), Film Grade

Material Notes: Applications
ALATHON L 4912 is a high molecular weight, high density copolymer with a broad molecular weight distribution. This resin provides excellent stiffness and a good balance of film properties as a single component or in blends. It is designed to process well on grooved feed or smooth bore equipment. L 4912 may be used in a variety of applications such as liners, over-wrap, multi-wall sheeting, merchandise and produce bags.

Regulatory Status
L 4912 meets the requirements of the Food and Drug Administration, regulation 21 CFR 177.1520.
