| description | A multilayer film includes a first and second outer layer each including a polymer; and an internal layer including an oxygen scavenger; where one of the first and second outer layers includes a blend of a polymer and an antifog agent, where the antifog agent includes one or more of glycerol fatty acid ester, polyglycerol fatty acid ester, polyethylene glycol fatty acid ester, polyethylene glycol alkyl ether, ethoxylated alkyl phenol, sorbitan ester, ethoxylated sorbitan ester, and alkanol; and wherein the first outer layer includes more than 3% and less than 8%, by weight of the first outer layer, of antifog agent. Unexpected improvements in oxygen scavenging and/or antifog properties of the film are obtained by the combination of the oxygen scavenger and antifog agent.
L'invention concerne un film multicouche comprenant une première et une seconde couche extérieure, chaque couche renfermant un polymère, ainsi qu'une couche intérieure renfermant un désoxygénant. L'une desdites première et seconde couches extérieures comprend un mélange d'un polymère et d'un agent anti-buée, cet agent anti-buée renfermant un ou plusieurs constituants choisis parmi un ester d'acide gras de glycérol, un ester d'acide gras de polyglycérol, un ester d'acide gras de polyéthylène glycol, un éther d'alkyle de polyéthylène glycol, un phénol d'alkyle éthoxylé, un ester de sorbitan, un ester de sorbitan éthoxylé, et un alcanol. La première couche extérieure comprend un agent anti-buée en proportion supérieure à 3 % et inférieure à 8 % en poids de ladite couche. La combinaison du désoxygénant et de l'agent anti-buée permet d'obtenir des améliorations inattendues des propriétés de désoxygénation et/ou des propriétés anti-buée de ce film. |
