Film of barrier EVOH with shock by autoclaving reduced

摘要

Film of barrier EVOH with shock by autoclaving reduced the present invention refers to a film barrier (1) that maintains a barrier of oxygen after being subjected to conditions.Sterilization in an autoclave.The film comprises a layer of EVOH (18) positioned as a core layer.And a layer of EVOH (14) positioned directly adjacent to an outer layer (12) composed of highly permeable material having a permeability of steam humidity greater than approximately 1.016 g mm / 65,35 cm2 - day - MPa (40 g - 1 / 100 inch2 - day - 2007).During sterilization by autoclaving.The barrier properties of the layer of EVOH (12) positioned adjacent to the outer layer (12) provides improved recovery of barrier properties of oxygen.In addition, for applications of reumedecimento, the inner layer of EVOH (18) maintains the oxygen barrier. Also described are methods to produce and use the film barrier described (10).
