The barrier layer restricts diffusion of said additive to the contents.

Abstract: A flexible film package having an adhesive based reclosable fastener having a flexible film substrate forming a plurality of package walls sealed to form an interior cavity for receiving a product; the plurality of walls having at least two opposing flexible walls; a package mouth, initially sealed, to permit access to the interior cavity; a low tack pressure sensitive adhesive (LTPSA) layer disposed on each of an exterior surface of the parallel walls, the LTPSA sized and oriented in positions to oppose one another at a plurality of positions when the package is reclosed to allow progressively decreased size of the interior cavity as product is removed; and wherein a bond strength of the LTPSA to the flexible film substrate is greater than an adhesion between LTPSA areas. The mouth can be formed by a peelable seal or by a defined area of weakness.

Abstract: A UV-curable pressure sensitive adhesive, a package having an adhesive-based reclosable fastener including the pressure sensitive adhesive, and a method of forming the package is described herein. The package includes a cavity and opposing panels configured to cover an opening to the cavity. The reclosable fastener is a UV-cured pressure sensitive adhesive comprised of one or more UV-curable acrylic oligomers, one or more tack control components, and, optionally, an elastomeric material. An adhesive component ratio defines an effective ratio made up of the weight percent of the UV-curable acrylic oligomer relative to the sum of the weight percents of the tack control component and elastomeric component, where the ratio provides a fastener with a first peel adhesion and subsequent peel adhesions effective to form the adhesive-based fastener into a reclosable fastener.

Abstract: Food packages comprising a tray with a cover sealed about a surrounding flange of the tray are provided, where the flange is non-planar. The flange can have a planar leading edge and a planar trailing edge that lie in planes angled relative to each other. Side edges of the flange extending between the leading and trailing edges can include non-planar segments in addition to planar segments. A recloseable feature can also be provided with the cover.

Abstract: A hybrid reclosable fastener with both mechanical mating and adhesive reclosable mating elements and a method of forming the hybrid reclosable fastener is described herein. Mechanical mating elements include mating portions having cooperating coupling parts configured to provide mechanical mating along with adhesive mating elements including an adhesive material formed on the cooperating coupling parts configured to provide an adhesive mating.

Abstract: A package configured to reclose after an initial opening and reduce head space in the package includes a plurality of walls with a pair of opposing wall segments, where each of the opposing wall segments have top and bottom edge portions, a width, a height, and facing inner surfaces. The plurality of walls are sealed to form an interior cavity to receive items therein, the cavity bounded by a bottom wall segment and an initially removably sealed upper mouth. The package further includes a low tack adhesive zone disposed across the entire width and extending from adjacent the mouth toward the bottom wall segment along at least a majority of the height of the facing inner surfaces. The adhesive zones have a greater affinity for adhesion to each other than to the items and permit the package to be repeatedly reopened and reclosed at a plurality of different heights to minimize headspace.

Abstract: A reclosable flexible package is suitable for retail sale of food products and is comprised of a film material. The flexible package includes a pair of curved semi-rigid strips attached to the walls of the flexible pouch and positioned parallel to the package opening. The curved semi-rigid strips are configured and arranged to nest together and bias toward one another. Upon removal of the top portion, the curved semi-rigid strips are moveable between a closed position and an open position. Further, the curved semi-rigid strips are configured such that they automatically reclose the package when the strips are released from the open position.
