Abstract:
A laminate structure is provided for forming a package, where the laminate structure allows for access openings to be provided upon peeling of the layers. The access openings may allow air to be introduced to the contents, such as to cause an exothermic reaction for heating items, or may allow product to be dispensed from the package. The laminate structure includes a first layer laminated to a second layer via an adhesive, and score lines are formed in the second layer to define plug areas and non-plug areas. The plug areas are configured to result in a peel interface line that occurs across a constant ratio of plug areas to non-plug areas along a predefined distance of a peel area of the laminate structure. Thus, when the first layer is peeled away from the second layer, the peel force needed remains relatively uniform across the predefined distance.
Abstract:
The present invention relates to a flexible packaging comprising a base layer and a film layer at least partially releasably affixed to the base layer via a pressure sensitive adhesive layer. The pressure sensitive adhesive layer comprises at least one adhesive zone and at least one adhesive-free zone extending continuously in a machine direction. The film layer is scored to form at least one pull tab which is disposed within the at least one adhesive-free zone and the base layer is scored to form at least one cavity which is disposed adjacent the at least one adhesive-free zone.
Abstract:
Improved packages and methods for constructing packages are provided that are designed such that the user can peel back a lidding member of the package to reveal an independently peelable portion covering one of the compartments. The independently peelable portion is a layer of the lidding member that maintains the respective compartment in an unopened (sealed) condition until the user independently peels that layer off to access the items in that compartment. The lidding member can be used to re-seal all of the compartments before and/or after the independently peelable portion is removed. The independently peelable portion may include a visual indication of a sealed condition of the compartment that serves as a tamper evidence feature. In multiple-compartment packages, peeling back the lidding member allows the user to access some of the compartments of the package, while at least one of the compartments remains sealed via the independently peelable portion.

Abstract:
A package and method of making a package are provided, where the package includes a removable flap portion built into one panel and a resealable flap portion built into the opposing panel. The package is constructed such that the removable flap portion overlies the resealable flap portion, and peeling away of the removable flap portion reveals a pressure sensitive adhesive (PSA) of the resealable flap portion and also provides a tamper-evident feature. Once the removable flap portion is peeled away, the consumer can access the contents of the package. The resealable flap portion can be folded over the newly-cut edge of the opposing panel and applied to the outer surface of that panel so as to reclose the package and maintain the contents of the package therein for later consumption.
Abstract:
A ready-made wrapper that can be used at home to wrap an article such as a snack bar and a method of making same is provided. The wrapper is a precision scored laminate comprising a flexible bottom layer adhered to a flexible top layer at least in part by a pressure sensitive adhesive (PSA). In one embodiment the bottom layer is scored so that one or more peripheral portions of the bottom layer can be removed and discarded, leaving a wrapper having an adhesive perimeter. After an article is placed in the center of the wrapper, the wrapper can be folded around the article to create an airtight package.
Abstract:
A structure is described for forming a wrapper, e.g., for print media, where the structure includes a line of weakness for facilitating a user's tearing of the wrapper to access the contents. The line of weakness may include a first line of weakness portion 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 portion that extends substantially perpendicularly to the respective longitudinal fold lines and a connecting line of weakness portion that extends between the first line of weakness portion and the second line of weakness portion and is disposed at a non-zero angle with respect to each. In this way, a tear initiated near the first line of weakness portion and may be propagated along the other portions to create an opening for accessing the product.

Abstract:
Containers are described that allow a consumer to see inside the container and to more easily access the products. One form of the container includes a base member with a lid defining a window. A flexible laminate with a peelable flap portion is attached to the lid to provide access to the products inside. The flexible laminate includes a first film layer laminated to a second film layer. The first film layer includes a first cut line defining a peelable flap portion and the second film layer includes a second cut line offset from the first cut line that defines an opening into the container. First and second reclose surfaces defined between the cut lines on the corresponding film layers include pressure-sensitive adhesive to allow the container to be re-sealed via movement of the peelable flap portion back into engagement with the flexible laminate remaining with the container.
Abstract:
A container is provided that has a compartment for storing an air-activated material for heating contents. The compartment is formed between a first web of material and a second web of material. The first web includes a first film layer laminated to a second film layer. A portion of the first film layer of the first web can be separated from the second film layer to reveal openings in the first film layer that allow air to enter the compartment. When the air contacts the air-activated material to activate the material, an exothermic reaction takes place that serves to produce heat, such as to heat the contents of the container. Prior to separation of the first and second film layers, the container is designed to allow ingress of oxygen into the compartment at a rate less than approximately 3 cc per 100 in2 per 24 hrs. at 23° C.
