CA 2267167
Films made by melt blending a clear or near-clear thermoplastic and certain well known non-toxic fungicides can be made into packages which will retard fungal growth on fungi-prone foods contained therein, even on food surfaces not in direct contact with the film. The fungicides are sorbic and benzoic acids, their salts and esters, and salts and esters of propionic acid.
On peut créer des emballages à partir de feuils fabriqués par mélange en fusion d'un matériau thermoplastique transparent ou pratiquement transparent et de certains fongicides non toxiques bien connus, ce qui retardera la croissance fongique sur des aliments contenus dans ces emballages et sur lesquels sont susceptibles d'apparaître des champignons, même sur des surfaces de produits alimentaires qui ne se trouvent pas en contact direct avec ce feuil. Ces fongicides sont des acides sorbique et benzoïque, leurs sels et leurs esters, ainsi que des sels et des esters d'acide propionique.
