Abstract
Multi-ply structures are provided that include a barrier film, which has a first polyester layer and a silicon oxide layer, a first adhesive layer, and a sealant film, where the first adhesive layer is located between the barrier film and the sealant film, and where the multi-ply structure has been microwaved in a pressurized vessel. Packages that are formed from the multi-ply structures are also provided in which these packages are microwaved in a pressurized vessel. Methods for sterilization are also provided.
