MULTI-LAYER FILM AND OSTOMY PRODUCT MADE THEREFROM

摘要

A multi-layer, chlorine-free film for use in an ostomy bag or pouch includes a barrier layer formed from a non-chlorine containing amorphous polyamide resin and a maleic anhydride modified olefin or an epoxy modified olefin. The barrier layer is substantially impermeable to malodor causing compounds. Tie layers are a maleic anhydride grafted resin and contact each side of the barrier layer. Inner layers contact respective tie layers. The inner layers are one of an ethylene propylene copolymer based resin, an ethylene-octene based resin and blends-thereof. Outer layers contact respective inner layers. Each outer layer is an ethylene vinyl acetate or ethylene methyl acrylate copolymer or a blend thereof, or a polypropylene-based resin and blend thereof. The film exhibits high tear strength and low noise levels.
