Abstract: A resealable package and method for making is provided. The package may comprise a laminate lidding member having an outer structure, an inner structure joined to the outer structure by an adhesive layer, and a pull tab. The laminate includes an outer line of weakness in the outer structure defining a separable opening portion and an inner line of weakness in the inner structure, defining a separable opening portion from the inner portion. The lidding member also comprises a second inner line of weakness formed in the inner structure, disposed between the pull tab and the inner opening portion, partially within the flange seal.

Abstract: The invention comprises an ovenable packaging structure having an integral one-way valve. The laminate structure comprises an outer layer having a cut line which defines a flap that is separable from the outer layer, wherein the outer layer is adhered to an inner layer having a cut line which is offset from the outer cut line and defines a portion that is separable from the inner layer along the inner cut line and defines an opening into the packaging structure. The adhesive between the layers comprises, in an embodiment, a channel of pressure sensitive adhesive which surrounds both the outer cut line and the inner cut line, wherein the channel of pressure sensitive adhesive defines the perimeter of at least one adhesive-free valve chamber within said channel. The valve chamber comprises at least a portion of the outer cut line and the inner cut line.

Abstract: A structure is described for forming a wrapper, e.g., for print media, where the structure includes lines of weakness for facilitating a user's tearing of the wrapper to access the contents. The lines of weakness may include a first line of weakness that extends along a fold line of an envelope fold forming one of the front or rear or right sides of the wrapped package, as well as a second line of weakness that extends substantially perpendicularly to the respective longitudinal fold lines and a third line of weakness that extends between the first line of weakness and the second line of weakness and is disposed at a non-zero angle with respect to each. In this way, a tear initiated near the first line of weakness and may be propagated along the other lines of weakness to create an opening for accessing the product.

Abstract: The invention comprises, in an embodiment, a resealable packaging structure comprising a container having a bottom and at least one sidewall extending upwardly therefrom, wherein the sidewall terminates in a flange. A flexible resealable lid is sealed to the flange. The lid comprises a polyethylene terephthalate layer disposed adjacent the flange, a pressure sensitive adhesive layer disposed adjacent the polyethylene terephthalate layer, and an oriented polypropylene layer disposed adjacent the pressure sensitive adhesive layer. The polyethylene terephthalate layer comprises a laser scored line which penetrates through the thickness of the inner layer but not through the outer layer and defines an opening portion that can be lifted out of the plane of the inner layer, thereby creating an opening through the lid defined by the laser score line.
