Forming webs and packages are provided having improved sealability to peelable lidstocks. The thermoformed containers (12) may have a mouth (14) having an opening and a flange being disposed about the opening, the flange formed from a forming web and having a thickness greater than about 12 mils and up to about 80 mils. The forming web may have a base layer (20) with a skim coating (24) thereon, a portion of the skim coating being on the flange having a skim coating thickness from about 2 mils to about 8 mils. A peelable lid (18) may include a film (28) with an inner lid sealant layer (26) which is sealed to the portion of the skim coating on the flange, the skim coating and inner lid sealant layer each having a common polyolefin majority component, the common polyolefin component being different than a majority component of the base layer.

A protection sheet is to be attached to a press through package that includes a sheet-shaped container including storing portions and a cover that seals the storing portions. The protection sheet includes a resin layer and a first adhesive layer. The resin layer is releasable from the press through package and includes slits from which the resin layer starts to be released. The first adhesive layer is bonded to the resin layer such that a surface of the first adhesive layer that is an opposite side from the resin layer is to be bonded to the cover.

A container including a paper-based cradle, a paper-based insert, and a thermoplastic film. The cradle has exterior corner panels that form a transition between the exterior end panels and exterior side panels. The cradle and insert are held together by the thermoplastic film that is thermoformed into conformance with the cradle and insert. The exterior corner panels at the junctures between the exterior end panels and exterior side panel can reduce the potential for defects in the thermoformed thermoplastic film.

A canister for holding one or more products. The canister includes a canister body having a first layer and a second layer laminated to the first layer. The canister body has a bottom end having a bottom panel offset from the bottom of the canister and a top end sealed with a lid.

The invention relates to a method for top sealing a cardboard tray lined with a plastic foil. The method includes the steps of providing a cardboard tray having a bottom, upstanding walls arranged along the periphery of the bottom and a horizontal flange arranged along the upper edges of the upstanding walls, wherein the inside of the cardboard tray is lined with a plast foil, which plastic foil extends at least onto the horizontal flange; arranging the cardboard tray in a lower sealing tool member having a compressible support edge, wherein at least the horizontal flange is supported by the compressible support edge of the lower sealing tool member; arranging a cover foil over the cardboard tray arranged in the lower sealing tool member to cover the opening of the tray defined by the upper edges of the upstanding walls; and pressing a heated upper sealing tool member onto the lower sealing tool member, wherein the cover foil, the plastic foil liner and the horizontal flange are pressed together to seal the cover foil onto the plastic foil liner along the horizontal flange. The overlapping area of the plastic foil liner, the cover foil, and the compressible support edge extends at least partially outside of the area of the horizontal flange.

A package for retaining a food item includes a tray with a base connected to at least one sidewall. The sidewall extends away from the base to a rim to define an inner chamber. The tray is made of a fluid impermeable material to retain fluids in the inner chamber. The package also includes a shelf made of the fluid impermeable material that is removably supported in the inner chamber such that the shelf is spaced apart from the base of the tray to permit an absorbent pad to be positioned therebetween. The shelf is configured to support the food item in the inner chamber separated from the absorbent pad.

A container including a paper-based cradle, a paper-based insert, and a thermoplastic film. The cradle has exterior corner panels that form a transition between the exterior end panels and exterior side panels. The cradle and insert are held together by the thermoplastic film that is thermoformed into conformance with the cradle and insert. The exterior corner panels at the junctures between the exterior end panels and exterior side panel can reduce the potential for defects in the thermoformed thermoplastic film.

A cardboard tray lined with a plastic foil having a bottom, upstanding walls arranged along the periphery of the bottom, upstanding walls arranged along the periphery of the bottom, and a horizontal flange arranged along the upper edges of the upstanding walls, wherein the inside of the cardboard tray is lined with the plastic foil, which plastic foil extends at least onto the horizontal flange and partially outside the area of the horizontal flange.

The disclosure relates to a cardboard box for holding content comprising liquid and/or gas. The box comprising: 3 or more side walls and a bottom side, a layer of liquid and/or gas non-permeable coating, every side wall having on its upper end a brim/collar area, the brim/collar area being folded to form an unbroken encircling receiving surface for attaching a lid foil.
