    摘要： A multi-layer, chlorine-free film for use in an ostomy bag or pouch (100) includes a barrier layer (12) having first and second sides. The barrier layer is formed from a non-chlorine containing amorphous polyamide resin present in a concentration of about 65 percent to about 100 percent by weight of the barrier layer and a maleic anhydride modified olefin or an epoxy modified olefin, present in a concentration of about 0 percent to about 35 percent by weight of the barrier layer. The barrier layer is substantially impermeable to malodor causing compounds. Tie layers (14, 16) contact each side of the barrier layer. The tie layers are a maleic anhydride grafted resin. The resin is one or more of an ethylene-based copolymer, a propylene-based copolymer, an ethylene-octene polymer and a styrene block copolymer. Inner layers contact respective tie layers. The inner layers (18, 20) are one of an ethylene propylene copolymer (polypropylene elastomer) based resin, an ethylene-octene based resin and blends thereof. Outer layers (22, 24) 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.
