A closure member for a food container including a multilayer laminate having a first layer of material at least partly light-permeable, a second layer of plastic material, a third layer of repositionable adhesive material interposed between the first and the second layer, at least one inner weakening line obtained on the second layer and extending according to a predetermined geometry defining, in use, an access gap to the container, at least one outer weakening line, obtained on the second layer, proximal to the peripheral edge with respect to the inner weakening line at least at the hand gripping portion, wherein the second layer has a predetermined graphic pattern printed or realised on at least one of its faces.

A package includes a container and a closure. The container includes a body formed to include a product-storage region adapted to store products therein and a brim coupled to the body and formed to include a mouth opening into the product-storage region. The closure is coupled to the brim of the container by melting a portion of the closure together with a portion of the brim to block access to the products stored in the product-storage region.

The present disclosure, in one embodiment, relates to a packaging assembly for holding liquids, viscous material, or particulate material. The packaging assembly includes a carton having side and bottom walls and an open top. A self-supporting plastic liner fits inside of the carton and is for containing liquids, viscous material, or particulate material. The liner has a side wall, a closed bottom end, and an open top end having an outwardly-projecting rim. The rim has a radially-extending flange portion, and a dependent skirt portion. When the self-supporting plastic liner is inside of the carton, the dependent skirt portion of the rim hangs over the side walls of the carton. A lidding material is removeably affixed to the rim of the plastic liner. A carton lid closes off the open top of the carton.

A ring-peel-seal liner is revealed, the ring-peel-seal liner includes a metal sealing layer and an adhesive layer. The metal sealing layer has a first annular tear line, and is defined into an annular region and a central region by the first annular tear line, wherein the annular region encircles the central region. The adhesive layer is adhered on one surface of the metal sealing layer. With the ring-peel-seal liner described above, the issue of needing an additional liner for enhancing a sealing effect after opening a conventional packaging container is resolved.

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 package is defined by a rigid base member and a peripheral flange surface. A flexible lidding member is heat sealed to the flange. The lidding member includes a first layer having a perimeter portion fixed to the flange and a second layer adhered to the first layer. An adhesive layer includes a permanent adhesive central portion and a perimeter pressure sensitive adhesive portion overlapping with the flange. A central score line is provided within the first layer, surrounding the central adhesive portion. A tab portion is formed as part of the perimeter portion of the lidding member and includes an edge score line formed in the first layer directly adjacent the fixed perimeter portion of the first layer.

A packaging device incorporating a breathable peel/reseal film and enabling a preservation process for allowing for the distribution, storage and multiple servings of a food product, particularly perishable food product(s), and initiating and controlling the transmission rates, respiration rates or deterioration of the perishable food product(s) and thereby, maintaining good internal and external food quality and normal development of flavor and aroma characteristics. The packaging device includes a plurality of atmospheric control attributes that modulates or controls the atmosphere within the packaging device as the food product(s) respire in order to promote the extended shelf-life of the food product and the maintenance of the quality and desirable marketable characteristics of the food product. The atmospheric control attributes can include perforations that may be positioned in breathable peel/reseal film portion of the package to allow the product respiration for multiple servings without substantially altering the shelf life extension properties of the packaging device.

The invention comprises, in an embodiment, a resealable packaging structure comprising a container having a bottom and at least one sidewall extending upwardly therefrom, wherein the sidewall terminates in a flange. A flexible resealable lid is sealed to the flange. The lid comprises a polyethylene terephthalate layer disposed adjacent the flange, a pressure sensitive adhesive layer disposed adjacent the polyethylene terephthalate layer, and an oriented polypropylene layer disposed adjacent the pressure sensitive adhesive layer. The polyethylene terephthalate layer comprises a laser scored line which penetrates through the thickness of the inner layer but not through the outer layer and defines an opening portion that can be lifted out of the plane of the inner layer, thereby creating an opening through the lid defined by the laser score line.

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.
