A first packaging material includes at least one layer located in both a first region and a second region. A second packaging material includes at least one layer located in both the first region and the second region. The hole includes a proximate position where the distance between the hole and the outer edge of the pouch in a center-of-gravity direction is shortest, the center-of-gravity direction being a direction in which a center-of-gravity line passing through the center of the pouch and the center of the hole extends. A communication part is connected with the hole at a position that is spaced apart from the proximate position in a direction orthogonal to the center-of-gravity direction. The outline of the communication part that extends from the hole to the outer edge includes a first line and a second line. The first line is located closer to the proximate position than is the second line. In the center-of-gravity direction, the distance from a first connection point to the outer edge is greater than the distance from the proximate position to the outer edge, the first connection point being a point where the first line is connected with the hole.

A product package includes a receiving space (1a), a covering film (7), an inner lining (6) and a body part (2) created out of a single blank. The body part (2) includes walls (2a, 2b, 2c, 8), a bottom (3) and a rim portion (4) as well as a plurality of slots (5) for shaping the receiving space (1a). The rim portion (4) of the body part (2) is a continuous, seamless and planar portion formed out of the same said blank and interconnecting the walls (2a, 2b, 2c, 8) of the body part (2).

A lidding film to use in food packaging, or the packaging of suitable non-food products, includes a substrate having an outer major surface on which is disposed at least a 5 heat-sealing layer (HS layer), a non-heat-sealing layer (NTIS layer), and a hydrophobic coating. On a side of the lidding film that corresponds to the outer major surface of the substrate is a peripheral region that encircles a central region. At least a first portion of the HS layer fills the peripheral region, and the NIS layer is absent as a cover on, or does not cover, the HIS layer in the peripheral region. At least a first portion of the NHS layer fills the 10 central region, and the HS layer is absent as a cover on, or does not cover, the NIS layer in the central region.

In an embodiment, the invention comprises a packaging structure comprising a cap layer which comprises post-consumer resin, at least one additional layer adjacent the first layer which comprises an alloy of: polyethylene terephthalate; a polyolefin; and at least one compatibilizer; a barrier coating adjacent the at least one additional layer and opposite the cap layer, wherein the barrier coating comprises a matrix of polyethyleneimine and polyvinyl alcohol and an overlacquer about the barrier coating. The methods of the invention may include co-extruding the cap layer and an alloy layer to form a co-extrudate; optionally, melt adhering the co-extrudate to another alloy layer to form a melt-adhered sheet; intermixing a solution of polyethyleneimine, polyvinyl alcohol, and water to form a coating; applying the coating to the outermost alloy layer opposite the cap layer; drying the applied coating; applying an overlacquer about the coating; and drying the overlacquer.

A first packaging material includes at least one layer located in both a first region and a second region. A second packaging material includes at least one layer located in both the first region and the second region. An outline of a communication part that extends from the hole to the outer edge of the pouch includes a first line and a second line. The communication part includes a first portion and a second portion. The first position includes a portion where the first line and the second line have a spacing from each other that decreases with increasing distance from the outer edge of the pouch toward the hole. The second portion is located between the first portion and the hole, and includes a portion where the first line and the second line have a spacing from each other of less than or equal to 2.0 mm.

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.

Heat-sealable packaging comprising an inner container (1) formed from a first flat sheet (3) of cellulose material, an outer shell (2), linked to an upper end of the container (1) in the vicinity of its upper opening, formed from a second sheet (6) of cellulose material, flat and die-cut, comprising at least one outer perimeter surface (9) giving rise to a flat surface around the upper opening of the container (1) for closing the container by heat-sealing of a plastic sheet, and a plastic coating film covering at least the inner side of the container (1) and the outer perimeter surface (9) of the enclosure (2). The first sheet (3) and the second sheet (6) have different and independent perimeter dimensions and outlines.

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.
