According to at least one exemplary embodiment, optimized packaging may be provided. Optimized packaging may be used, for example, as packaging for leafy green products, produce, or other food items. The optimized packaging may have a frame element and one or more film surfaces.

The present invention relates to a resealable container comprising: a polyethylene terephthalate-based container body comprising a bottom side and at least one upwardly extending sidewall, wherein the sidewall terminates in an open end of the container; a flexible film sealed to the container body, over the open end of the container, wherein the flexible film comprises: a polyethylene-based first film layer; a pressure sensitive adhesive layer adjacent a lower surface of the first film layer; a polyolefin plastomer skin layer adjacent a lower surface of the pressure sensitive adhesive layer, wherein the first layer, pressure sensitive adhesive layer, and skin layer are coextruded; and a heat seal layer printed onto a lower surface of the skin layer and heat sealed to the container body.

A flexible packaging laminate is formed to have a built-in opening and reclose feature by forming the laminate as a two-part structure having an outer structure joined in face-to-face relation with an inner structure. Score lines are formed in both structures to enable an opening to be formed through the laminate by lifting an opening portion (e.g., a flap or the like) of the two structures out of the plane of the laminate. The score line through the outer structure defines a larger opening than the score line through the inner structure, such that a marginal region of the outer structure extends beyond the edge of the opening portion of the inner structure. A pressure-sensitive adhesive is used to re-adhere the marginal region to an underlying surface of the inner structure adjacent the opening through the laminate.

A battery package is described herein that advantageously maintains separation between batteries received therein while also providing a resealable opening to sequentially retrieve batteries therefrom. Further, the battery package can include an outer covering.

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.

Tamper-evident, re-closable lidding films and systems thereof that makes unauthorized access to a protected object easily detected. Color-changing anti-tampering packages and methods thereof.

The present invention relates to a resealable container comprising: a polyethylene terephthalate-based container body comprising a bottom side and at least one upwardly extending sidewall, wherein the sidewall terminates in an open end of the container; a flexible film sealed to the container body, over the open end of the container, wherein the flexible film comprises: a polyethylene-based first film layer; a pressure sensitive adhesive layer adjacent a lower surface of the first film layer; a polyolefin plastomer skin layer adjacent a lower surface of the pressure sensitive adhesive layer, wherein the first layer, pressure sensitive adhesive layer, and skin layer are coextruded; and a heat seal layer printed onto a lower surface of the skin layer and heat sealed to the container body.

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.

The present subject matter relates to a label lid for sealing an opening in a packaging container. The label comprises a facestock layer, a removable adhesive layer, a heat-seal layer, and an optional release coating, wherein the removable adhesive layer does not include a release liner. The removable adhesive layer can be coated on the heat-seal layer or the facestock layer. Optionally, a release coating can be applied to the heat-seal layer or the facestock layer. The composition of the layers used in specific arrangements provides unique performance characteristics for the label for improved sealing, reclosure, and matrix stripping properties.

The present invention relates to a resealable container comprising: a polyethylene terephthalate-based container body comprising a bottom side and at least one upwardly extending sidewall, wherein the sidewall terminates in an open end of the container; a flexible film sealed to the container body, over the open end of the container, wherein the flexible film comprises: a polyethylene-based first film layer; a pressure sensitive adhesive layer adjacent a lower surface of the first film layer; a polyolefin plastomer skin layer adjacent a lower surface of the pressure sensitive adhesive layer, wherein the first layer, pressure sensitive adhesive layer, and skin layer are coextruded; and a heat seal layer printed onto a lower surface of the skin layer and heat sealed to the container body.
