Eastman D4008-F Polyethylene (discontinued **)
Categories:	Polymer; Thermoplastic; Polyethylene (PE); Low Density (LDPE)
Material Notes:	Polyethylene D4008-F is a fractional melt formulation designed for film applications. It is suggested for applications requiring toughness and clarity List of Applications: Food packaging Food-contact applications D4008-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.
