Celanese Ateva® 1221L Film Ethylene Vinyl Acetate Copolymer Film (discontinued **)
Categories:	Polymer; Film; Thermoplastic; Ethylene Vinyl Acetate; Ethylene Vinyl Acetate Copolymer (EVA), Film Grade
Material Notes:	Ateva® 1221L resin is suitable for co-extrusion and blending applications where superior strength, good heat seal, and hot tack characteristics are required. This EVA resin may be safely used as articles or components of articles intended for uses in contact with food as provided in FDA regulation 21 CFR 177.1350 - Ethylene-vinyl acetate copolymers, subject to extraction limitations on the finished food-contact article as specified in that regulation. This polymer may be processed on conventional extrusion equipment. It is recommended that the melt temperature be kept below 210°C as decomposition can occur at higher temperatures. Properties listed are for a film produced on a 24:1 L/D, 40 mm extruder with a 100 mm die, at a melting temperature of 210°C. Additives: low A/B, low slip Applications: Flexible Packaging Information provided by Celanese Corporation.
Key Words:	co-extrusion and blending applications requiring superior sealability and strength
