The present invention is related to a flexible laminate for forming a reclosable packaging container comprising a built-in opening and reclose feature, said laminate comprising an inner structure and an outer structure, adhesively joined face-to-face, the outer structure forming the outer surface of the container and the inner structure forming the inner surface of the container, the outer structure comprising an outer flap portion delimited by a scoring line through the outer structure, and an inner structure comprising an inner flap portion delimited by a scoring line through the inner structure, the inner score line and the outer score line creating an opening into the container when the flap portions are peeled back, a marginal region of the outer flap portion extending beyond an edge of the inner flap portion and overlying an underlying surface of the inner structure, the inner and outer flap portions being joined in a second adhesive region and the first adhesive region being disposed between the marginal region of the outer flap portion and the underlying surface of the inner structure for attaching and re-attaching, in use, the outer flap portion to the underlying surface, wherein the bond/peel strength, measured according to ASTM F904-1998 (reapproved 2008), of the first adhesive region is smaller than the bond/peel strength of the second adhesive, the first adhesive being permanently tacky and covering the entire surface of either the inner structure or the outer structure, said first adhesive being patterned covered by an adhesion promoter, trans forming said first adhesive into a second adhesive and creating patterns of first adhesive region and second adhesive region.

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.

An ovenable package comprises an ovenable receptacle configured to hold a food product. The receptacle has an open face surrounded by a rim. An ovenable laminated film lid is attached to the rim of the receptacle by a welded seal between a lower face of the laminated film lid and the rim of the receptacle. The laminated film lid comprises a first layer, a second layer above the first layer and a resealable adhesive between the first and second layers. An unopened package is openable by separating the second layer from the first layer in a peripheral region. The opened package can be reclosed to a ventable state by reattaching the second layer to the peripheral region of the first layer by the resealable adhesive. The ventable state permits venting of gas from an interior of the receptacle between the second layer and the peripheral region of the first layer.

A reclosably sealed cup, and a multi-layer web and method for production 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.

A multi-compartmental peel/reseal package having a peel/reseal label member. The multi-compartmental peel/reseal package includes a substrate forming at least a portion of a package body. The substrate includes a plurality of circumferential slits in the substrate, each circumferential slit defining an opening cover corresponding to an opening in the package body. The label member is adhered to the substrate and is configured to cover the plurality of circumferential slits and seals the openings. A selectively applied adhesive is present on a surface of the label member forming a high tack area and a low tack area. The positioning of the high tack area provides attachment of the label member to the substrate and seal each of the openings in the package body. The positioning of the low tack area permits peeling and release of the label member from the substrate.

A resealable closure for packages is provided which has a package integrity feature. The closure includes a two-ply material having an inner film layer and an outer film layer, forming a top of container. The outer film layer has a sealing panel completely covering a first panel and a second panel of the inner film layer. The sealing panel is permanently attached to the first panel and is releasably affixed a portion of the inner film layer around the perimeter of the first panel to form an opening in the top when the sealing panel with affixed first panel is peeled back from the top. The sealing panel is resealable against the top to seal the opening when the sealing panel is moved back against the top. The package integrity feature comprises the second panel of the inner layer which separates from the sealing panel to indicate that the container has been previously opened.

A recloseable package is provided having a tamper-indicating element. The tamper-indicating element include one or more self-terminating shapes that form one or more chads after opening the recloseable package. Advantageously, the self-terminating shapes provide a simple, visual cue of graphical alignment in the seal to show the customer whether or not a package has been opened.

A resealable package includes a bottom portion defining an interior and including a sealing surface extending about a top of the interior; a film coupled to the bottom portion along at least a portion of the sealing surface and including a tab portion extending inward from one side of the top film; and a seal disposed between the film and the bottom portion and including at least first and second sides that intersect and form a seal portion tip. The seal seals the film to the bottom portion such that the film is configured to be resealably peeled away from the bottom portion along at least a portion of the seal area upon application of a force to the seal tip portion via the tab portion.

A container including a containment wall, defining an internal containment volume and including a free edge, a closing element including a welding layer welded onto the free edge of the wall and a front layer defining an outer surface of the container. An intermediate layer of removable self-adhesive is spread onto an adhesion portion of mutually coupled surfaces of the welding layer and front layer. An opening line adapted to define an access window is obtained through an incision in a stretch of thickness of the welding layer splitting the welding layer into a welding portion adapted to be welded to the container and an opening portion corresponding to the access window, with reference to an assembled configuration on the container. The incision is made to allow the detachment of the opening portion from the welding portion while the closing element is opened.
