<p>The present invention relates to a laminate film having utility as a material from which to manufacture surgical and other protective garments. The laminate film comprises a first layer formed from a polyetherester copolymer material produced from the condensation reaction of dimethyl -1, 4cyclo hexane dicarboxylate 1, 4-cyclo hexane dimethanol and poly(tetramethylene ether glycol) and a second layer comprising a first material selected from the group consisting of an ethylene-vinyl acetate copolymer material, a second polyetherester material, an ethylene methacrylate copolymer material, an anhydride modified polyolefin copolymer material, and a polyether block amide copolymer material. The polyetherester copolymer material produced from the condensation reaction of dimethyl -1, 4-cyclo hexane dicarboxylate 1, 4-cyclo hexane dimethanol and poly(tetramethylene ether glycol) is present in an amount 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 formed using a coextrusion process. Alternatively, a laminate material may be formed by blending together the aforementioned materials in layers and extruding them through a single die. The laminate film of the present invention may be bonded to one or more layers of a non-woven material selected from the group consisting of polyester based materials, polyolefin based materials, and polyamide based materials. A corona treatment may be effected to increase the bond strength between the laminate film and the non-woven material layer(s).</p> |
