主权项

1. A package having a first compartment, the package comprising:
a flexible laminate film comprising a bottom layer bonded to a top layer with a permeant adhesive, the bottom layer and the top layer being substantially coextensive; the bottom layer comprising a substrate and a continuous resinous frangible skin layer; the top layer being precision scored to form an overcut which defines a periphery of a flap; the substrate being precision scored to form one or more undercuts, each undercut defining a die cut section; wherein the frangible skin layer is located on an outer facing surface of the substrate between the substrate and the top layer and within the flap periphery; and wherein lifting the flap from the bottom layer removes the die cut sections from the bottom layer to create air holes in the bottom layer through which air can pass to the first compartment.
