Estimating the term…
A multilayer heat-sealable chlorine-free film of relatively low modulus, high interlaminar strength, and low noise upon flexing is provided. The film includes an odor barrier layer and at least one directly adjoining heat-sealable skin layer. The barrier layer is composed of either an aliphatic or partially aromatic polyamide resin, or a blend thereof, blended with an ionomer resin consisting essentially of a partially neutralized ethylene-methacrylic acid copolymer, and the heat-sealable skin layer or layers bonded directly to the barrier layer are composed of copolymers of ethylene and an ester-containing comonomer. High resistance to delamination of the barrier layer and skin layer(s) is achieved without tie layers therebetween. Pouches formed of such multilayer chlorine-free films are also disclosed.
A multilayer heat-sealable chlorine-free film of relatively low noise, low modulus and high interlaminar strength, consisting of an odor barrier layer and at least one adjoining heat-sealable skin layer in direct contact with said barrier layer;
An ostomy pouch having two side walls each consisting of a multilayer chlorine-free film having an odor barrier layer coextruded with at least adjoining one heat-sealable skin layer in direct contact therewith;
