<p>An autoclavable, transparent multilayer film with oxygen barrier capacity assembled of thermoplastic materials, capable of being processed into hollow shapes and useful for the packaging of oxygen sensitive goods. The film is assembled in sequential layers A-B-C-D-C-B'-A' wherein A and A' are layers substantially resistant for water and water vapor; B and B' are layers providing adhesive bondings between layers A and A' with C; C is a layer of a moisture absorbing polymer substantially impermeable for oxygen which contains an aromatic polyamide or a derivate or a copolymer thereof; D is a layer consisting of polyethylene-vinylalcohol (EVOH) with a molar ethene concentration between 0-80 %.</p> |
