Abstract: An improved lamination structure is disclosed for use as a packaging material, particularly a material formed by a combination of a foil layer with a PET layer with integral adhesive; and then applying a sealant polymer to the exposed PET surface. The resulting structure preferably exhibits adequate structure and sealing temperatures desirable for packaging of cream cheese and similar foodstuffs, and further exhibits flow and caulking while minimizing or avoiding impact to material deadfold.

Abstract: An improved printed film that achieves the dissipation of static electricity is disclosed. The improved film dissipates charge that is typically built up during the processing, handling and use of such film. One embodiment involves the selective overprinting of coating material(s) to form a continuous path that is electrically dissipative and/or conductive, which thereby enables the dissipation or equalization of static charge.

Abstract: A lidding material and a container using such material, where the lidding material includes a sealant layer, a biaxially-oriented film, and a thin metallic foil layer having a thickness not greater than about 0.0005-0.0007 inches, where the thin metallic foil layer is adhered to one side of the biaxially-oriented film, and the sealant layer is applied to an opposite side of the biaxially-oriented film.

Abstract: Film is used as a bladder that expands in response to an increase in the internal pressure while contents are heated, such as micro-waved. A laser-scored vent(s) is provided with scoring of an reduced extensibility layer, such that expansion of the package due to internal pressure (steam) pulls the film across the width of the package causing it to stretch to the point that the vent point(s) breaks through or ruptures the sealant film allowing the pressure/steam to escape.

Abstract: A storage bag for perishable articles includes an unperforated outer layer, an unperforated inner layer, and an intermediate layer disposed between the outer and inner layers. The intermediate layers includes a solventless adhesive mixed with a volatile antimicrobial. In addition, the outer and inner layers are oxygen permeable, and the inner layer has a greater permeability than the outer layer.

Abstract: A bag suitable for use in microwave cooking is constructed of an elongated tube of flexible material closed at one end by means of a cold seal closure and having a heat seal adhesive deposit applied to the other end thereof for use in closing the bag after filling thereof; and methods of making the same are described, including the making of a roll from which said bags can be made.

Abstract: A bag suitable for use in microwave cooking is constructed of an elongated tube of flexible material closed at one end by a cold seal closure and having a heat seal adhesive deposit applied to the other end thereof for use in closing the bag after filling thereof to form a package. In another embodiment, a package suitable for use in microwave cooking is constructed of an elongated tube of flexible material closed at one end by a cold seal closure and having a cold seal adhesive deposit applied to the other end thereof for use in closing the bag after filling thereof. Methods for making bags and packages including methods for making rolls from which bags and packages may be made.

Abstract: A bag construction comprising an outer bag and an inner bag contained therewithin and a method of making the same is described. The bag construction is made from a tube length having inner and outer portions, by cross sealing the inner portions and folding the outer portions into a rectangular shaped bottom. A patch is attached to the bottom folds to cover the same and provide an added moisture and vapor barrier.

Abstract: A bag of the leakproof square ended type having an end formed by a first fold portion having a rectangular tab and a triangular fold portion is made with the tab secured to a central portion of the end with the triangular fold portion inserted beneath the tab so as to be held thereby in a releasable position, the triangular fold portion being manually removable from said releasable position for use in providing a pour spout. The bag end may also be provided with a handle means for use in carrying and/or dispensing purposes.

Abstract: A carton-type container has a lid which is snapped into place on top of a paperboard outer shell having a sift-proof inner liner. The lid is provided with a re-closable pour opening through which the product contained within the container can be repeatedly dispensed therefrom.

Abstract: A lined container is provided with a transparent liner and a pair of tear strips in an endwall of an outer carton removable to provide windows extending along the vertical extent of the endwall. The level of the contents of the carton is visible through the windows and the transparent liner.

Abstract: A bag construction comprising an outer bag and an inner bag contained therewithin and a method of making the same. The bag has an independent unitary construction. The bag construction is made from a tube length having inner and outer portions, by cross sealing the inner portion and folding the outer portion into a rectangularly shaped bottom.

Abstract: A reclosable container having a box-like configuration is provided with means for severing the front and side walls thereof along a strip spaced below the upper end thereof for defining a hinge portion in the back wall end to divide the carton into a lid and a base.

Abstract: A bag of the gusseted square-bottom type having a generally rectangular bottom including a rectangular bottom fold portion and a triangular bottom fold portion is made with the triangular fold portion overlapping the rectangular fold portion. The triangular fold portion is sealed at the outermost ends thereof to define an inner enclosed space which communicates with the interior of the bag so that it can be extended from the bag bottom as the bag expands during a microwave cooking operation to form a fin-like extension.

Abstract: The bottom of a gusseted, square-bottom bag is sealed by applying a fin seal, a cross seal which intersects the fin seal, and a third seal at the intersection of the fin seal and the cross seal.

Abstract: A carton structure for use in forming a lined carton wherein an insert is retained and positioned between the carton blank and the liner so as to permit removal thereof without opening the liner.

Abstract: A package with a stretchable tear element for opening the package. In a preferred embodiment the tear element extends over a packaged article and beneath a covering plastic film formed over the article to secure the article to a supporting panel. The tear element is capable of stretching sufficiently, when the plastic film is drawn down in a softened condition over the product to form the package, so that the film can conform itself and the tear element substantially to the shape of the product and any tendency of the film to form a tent across an initial span of the tear element is minimized. The tear element further stretches, in part within the package, when one end is pulled back across the film so that a portion of the element moves past the film at the exit point, producing a slicing or sawing action, while at the same time it remains essentially anchored at the opposite end. The panel is preferably foldable to form a box.
