ABSTRACT:
The present invention relates to a laminate film useful as a material from which to manufacture surgical and other protective garments. The laminate film comprises at least one layer formed from a first polyetherester copolymer produced from the condensation reaction of dimethyl-1,4-cyclo hexane dicarboxylate and 1,4-cyclo hexane dimethanol and poly(tetramethylene ether glycol) and a second layer comprising a material selected from the group consisting of an ethylene-vinyl acetate copolymer, an ethylene methacrylate copolymer, a second polyetherester copolymer, an anhydride modified polyolefin copolymer, and a polyether block amide copolymer. The total amount of the first polyetherester copolymer present in the laminate is greater than or equal to 35 wt. % of the total weight of the laminate film to provide strength to the laminate film. The laminate film may be bonded to one or more layers of polyesters, polyolefins, polyamides, and non-woven fabrics.
