Patent

CA 2481109

A breathable film involving at least one polymeric layer of 100% neutralized ionomer containing sufficient aliphatic, mono-functional organic acid salt to essentially triple the oxygen transmission value (OTV) and/or at least one polymeric layer of metallocene polyethylene (mPE) optional blended with low density polyethylene and preferably in combination with one or more outer layers of highly neutralized ionomer (e.g., Surlyn®). Such polymeric film and polymeric film structure has sufficient oxygen permeability, water vapor transmission, formability, and structural strength to be useful in wrapping food products requiring breathable films such as case ready meat, fish, sausage, fresh produce, and the like.

Cette invention concerne un film respirant comprenant au moins une couche polymère d'un ionomère neutralisé à 100 % renfermant en quantité suffisante d'un sel d'acide aliphatique mono-focntionnel pour essentiellement tripler la valeur de transmission d'oxygène, et/ou au moins une couche polymère d'un polyéthylène métallocène (mPE) éventuellement mélangé à un polyéthylène basse densité, de préférence en combinaison avec une ou plusieurs couches extérieures d'un ionomère fortement neutralisé (tel que Surlyn®). De part leur une perméabilité à l'oxygène, leur capacité de transmission de la vapeur d'eau, leur formabilité et leur robustesse structurale suffisantes, de tels films polymères et structures de film polymère conviennent pour l'emballage de denrées alimentaires nécessitant l'emploi de films respirants telles que viandes, poissons, saucisses, produits frais et analogues préemballés.
