Abstract: This disclosure describes a secure access, easy opening tamper evident feature for sealable bags. The tamper evident feature provides dual zones for tamper-detection and may be sealed within a bag to form a package in such a manner that allows for the filling of product into the package and the handling of the package to be safely made, as the tamper evident feature may be positioned away from deleterious contact with the product. The package may be a combination of the tamper evident feature and a flexible bag. The package may include an easy opening end configuration for secure access inside the bag when the tamper evident feature is exposed and subsequently torn open by an end-user along the dual zones for tamper detection. The package may be formed with bags having side gussets or, alternatively, with folded-closed end. Methods for making and filling such packages are also provided.

Abstract: A packaging system is provided including a container having a plurality of walls and a flexible liner film placed in a product receiving chamber defined by the walls. The liner film comprises a base film having a first surface, a second surface and at least one side margin. A cold seal cohesive material layer is applied to the second surface of the base film so that at least a portion of at least one side margin of the base film is substantially free of cold seal cohesive material. A release film is laminated to the cold seal cohesive material layer and at least partially overlaps a portion of side margin substantially free of cold seal cohesive material.

Abstract: The present invention provides a flexible multilayer packaging film and packages formed therefrom wherein the films include a first film layer comprising a first biaxially-oriented polymer selected from the group consisting of a polyester, a polyolefin, a polyamide, and a blend thereof and a surface-roughened portion, a second film layer comprising an adhesive, a third film layer comprising a barrier material, a fourth film layer comprising a second biaxially-oriented polymer selected from the group consisting of a polyester, a polyolefin, a polyamide, and a blend thereof and at least one score-line; wherein the packages comprise a tear-initiation area and a directional tear zone.

Abstract: A multilayer film with an integrated peelable coupon that may be used as a packaging unit for products is described. The flexible, multilayer film has at least a first polymeric layer, indicia, a layer of release coating that is applied in a pattern to a portion of an interior surface of the first layer and a second polymeric layer which may be made in combination with additional layers. A removable portion of the film structure is provided by a pattern of perforations or slits through certain layers of film in alignment with the release coating pattern. The method of manufacturing the multilayer film with an integrated coupon includes providing a first polymeric layer as an outer layer, printing indicia, applying a layer of release coating in a pattern to a portion of an interior surface of the first layer, cutting slits through certain layers and laminating a second polymeric layer.

Abstract: Multilayered laminate films for food packaging applications which comprise at least: (a) a layer of oriented or nonoriented polyester terephthalate or oriented or nonoriented polypropylene, (b) a layer comprising at least one metal, and (c) a layer comprising at least one additive suitable for incidental food contact which provides protection against corrosion to a layer containing at least one metal is described.

Abstract: A microwavable package for storing and cooking a food product such as bacon, includes an absorbent bed enclosed within a sealed plastic sleeve. During microwave cooking, the corrugated bed collects oil or grease released by the food product and maintains a portion of the food product in contact with the collected oil or grease to impart a pan-fried quality to the cooked food product. Vents in the sleeve permit the controlled escape of water vapor so that the sleeve billows away from the food product during cooking. An inert, oxygen-free atmosphere is contained within the package, and a pulrality of the microwavable packages are enclosed in a sealed outer barrier wrap prior to their removal for cooking.

Abstract: A single piece non-wrinkling wrapper for bars of soap is made from a lamina of sheets of a flexible plastic film and a water absorbent paper. The film and paper are superimposed and bonded together along their margins by bands of adhesive. The exposed surface of the paper sheet is coated with a cold seal cohesive along the margins in register with the adhesive bands. When wrapped around a bar of soap, the cohesive and adhesive fall in the back seal and end seal areas of the soap, thereby double wrapping the bar with the film and paper sheets and with an air space between the sheets which prevents or minimizes the wrinkling of the outer wrap. The wrappers may be made on a continuous basis from a wide web of film and paper that are bonded together along a grid-like pattern by means of bands of adhesive. The web is severed along the midpoints of the adhesive to form the individual wrappers.

Abstract: A composite wrapper combining a rigid foldable member joined to a flexible packaging film member, wherein the rigid member is the inner element and provides a sleeve or box-like support when the package is completed and the flexible member is the outer element and extends beyond either side of the rigid member so as to be folded to complete the package enclosure. The rigid member includes a base panel having liftable flaps which can be raised to an upright position and wall panels which can be folded about an article packaged in the wrapper.

Abstract: Nylon resins are extrusion coated onto various substrates for the manufacture of coated packaging films by heating the nylon resin to a melt temperature of 450.degree.-550.degree.F, extruding the molten resin onto a chill roll through a die which is set at an angle to the chill roll, employing sub-atmospheric pressure between the extruder die and the chill roll, rapidly cooling the extruded film on the chill roll to form a substantially amorphous nylon, and thereafter joining the nylon to a substrate.
