ABSTRACT:
The invention discloses a multiple layer packaging film, packages made therefrom and a method of opening the packages. The invention provides inseparable seal strength and in some cases hermetic seals, in combination with peelable ply separation opening for access to the contents of the package, while at the same time providing excellent barriers to transmission of oxygen and moisture. Certain embodiments provide for improved abuse resistance, excellent graphics, and other improvements. The method of opening the package depends on separating opposing ones of the package sidewalls, forcing the opening tear to be propagated partially through the film to a peelable layer interface, with subsequent ply separation along the interface to effect completion of opening of the package.
