Eastman D4028-F Polyethylene (discontinued **)
Categories:	Polymer; Thermoplastic; Polyethylene (PE); Low Density (LDPE)
Material Notes:	D4028-F is a low density formulation which contains high antiblock. It is suggested for film applications that require reasonable clarity. D4028-F meets the requirements of FDA regulations at 21 CFR 177.1520(c)(2.2) and may be used as a component of packages used for holding food during cooking. However, the polymer thickness in the form in which it contacts food shall not exceed 0.005 inches and contact is limited to non-alcoholic food because of a regulatory limitation for an adjuvant substance in this formulation. Information supplied by the manufacturer. Information from manufacturer data sheet. Eastman Chemical Company sold its polyethylene business to Westlake Chemical Corporation in Dec. 2006. This grade no longer appears in the Westlake product line.
Key Words:	High antiblock, reasonable clarity
