Abstract: A multilayer film is provided having barrier protection for high acid foods. The film generally comprises an inorganic core layer comprising a substrate layer upon which an inorganic barrier layer is disposed and at least one outer barrier layer. The outer barrier layer has a core layer that may consist of a barrier layer surrounded by two outer sealant layers. The composite maintains excellent barrier properties at higher temperatures and humidities in order to maintain shelf stable package after it is aseptically or hot filled. The barrier properties of the composite is not significantly affected upon flexing of the film.

Abstract: A microwaveable package includes a support member; a bottom web; a food product; and a top web; where the seal between the top and bottom webs has a peel strength, before microwaving, of at least 4 pounds per inch, and a peel strength, after microwaving, of less than 2.5 pounds per inch. Alternatively, a microwaveable package includes a support member; a bottom web; a food product; and a top web; where the top web includes a sealant layer comprising an ethylene/alpha olefin copolymer, and the bottom web includes a sealant layer comprising a blend of between 60% and 90%, by weight of the sealant layer, of ethylene/vinyl acetate copolymer, and between 10% and 40%, by weight of the sealant layer, of polypropylene. Methods of making the microwaveable packages are also disclosed.
