Westlake Elevate™ EF545AW 4.0% EVA copolymer
Categories:	Polymer; Thermoplastic; Ethylene Vinyl Acetate
Material Notes:	EF545AW resin is a 4.0% VA ethylene vinyl acetate copolymer with high antiblock designed for stretch and other film applications where cold temperature performance and low C.O.F. are needed. This grade provides reasonable optics even with the high antiblock loading necessary to achieve the low C.O.F. Excellent cold temperature performance, toughness, and resistance to load deformation make EF545AW a wise selection for wrapping pallets stored in food freezers and other cold environments. Test specimens for blown film: nominal thickness 1.5 mils; blow up ratio 2.4:1, die gap 35 mils. This product has some 21 CFR clearances. Application/Uses: Pallet wrap stretch film- Food packaging stretch film. Samples tested at 23°C and 50% RH. Information provided by Westlake Chemical Corporation.
