A reclosable package, and a machine and method for making that reclosable package that includes a tray for receiving a product and a substantially horizontal edge, wherein the horizontal edge extends circumferentially on an upper side of the tray and has a clamping portion releasably connected thereto. The package includes a top film across the tray, the edge and the clamping portion, and which may be releasably connected to the edge by a first sealed seam to seal the tray in a gas-tight manner. The top film may be connected to the clamping portion by a second sealed seam. A side face of the tray may include an undercut provided with a projection, the projection being suitable for locking the clamping portion in position when the clamping portion has been detached from the edge and is located between the projection of the undercut and the side face of the tray.

A resealable closure for a container in which package integrity is indicated by a structure which connects the closure to a remaining portion of the container which must be broken in order to gain access to the contents of the container for a first time. The package integrity feature, in one form, includes a structure associated with the closure, wherein upon opening the closure for a first time, the structure stretches, increasing a length of the structure until the structure eventually breaks, leaving one or both residual ends of the broken structure rippled or curved upward from the remainder of the container. In one alternative form, the structure is associated with a pull tab of the sealing panel, which comprises the closure, whereby either the structure must be broken first, prior to pulling back the sealing panel, or while pulling back the sealing panel for a first time, the structure breaks, prior to gaining access to the contents therein. Advantageously, the package integrity feature is integrally formed with the closure and a remaining portion of the container. Integrity of the package is indicated by visually observing an intact breakable structure.

A resealable closure for a container or package in which package integrity is indicated by a structure which breaks and/or produces an audible sound when the resealable closure is opened for a first time. The package integrity feature, in one form includes at least one strip or frangible structure that is initially affixed to two portions which comprise the resealable closure so that upon opening the resealable closure for a first time, at least one of the strips breaks. The strips may include a weakened portion such as a narrowing. Integrity of the package is indicated by an intact strip viewable upon opening the resealable closure and conversely, a broken or non-intact strip would indicate that the resealable closure has been previously opened. Package integrity may also be shown by a moveable second panel or moveable die cut tab portions.

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.

A composite container is provided for holding products (e.g., stacked chips). The container includes a tubular body and a peelable membrane. The tubular body is made of at least one paperboard body ply having an inner surface and a metallized Oriented Polypropylene (mOPP) liner ply adhered to the inner surface of the paperboard body ply. A liner sealant is disposed on the inner surface of the mOPP liner ply, and the paperboard body ply and the mOPP liner ply are rolled outwardly to form a rim. The membrane, which has a membrane sealant on its inner surface, is sealed to the liner sealant in the area of the rim to close the container. When the membrane is peeled away, the membrane sealant and the liner sealant remain sealed to each other and cause separation within the mOPP liner ply, avoiding tearing and exposure of the paperboard in the rim.
