Abstract: A metallized thermoplastic label includes a first skin layer containing a thermoplastic and a first cavitating agent, wherein the first skin layer has a first side and a second side, the first skin layer is cavitated, and the first side of the first skin layer is adapted to be used in contact with a cold glue adhesive. The label further includes a cavitated core layer and a second skin layer that is metallized. The particle size of the cavitating agent in the core layer is selected to achieve a desired appearance, especially luster, of the metal layer.

Abstract: A clear polymeric label including a delaminatable mask layer is provided. The label includes a non-cavitated mask layer having a first side that is suitable for forming a cohesive bond with an adhesive, preferably a water-based adhesive. The cohesive bond between the first side of the mask layer and the adhesive is grater than the cohesive bond between the second side of the mask layer and its adjacent layer, whereby attempted removal of the label results in separation of the mask layer, which remains attached to the container, and masks the adhesive.

The label includes a non-cavitated mask layer having a first side that is suitable for forming a cohesive bond with an adhesive, preferably a water-based adhesive. The cohesive bond between the first side of the mask layer and the adhesive is greater than the cohesive bond between the second side of the mask layer and its adjacent layer, whereby attempted removal of the label results in separation of the mask layer, which remains attached to the container, and masks the adhesive.

Abstract: A polymeric film structure having a cavitated skin layer with a cold seal adhesive applied thereto. The cold seal adhesive may be applied to the cavitated layer in the absence of pretreatment or precoating. When used in packaging applications, the film structure provides a tamper evident seal. This same film structure may also be used in pressure sensitive labeling applications without a releasable liner.

Abstract: A polymeric film structure having a removable scratch off layer particularly suitable for use on “scratch and reveal” devices including instant lottery tickets, “scratch and win” game cards, and various other promotional items. The film structure includes an opaque cavitated layer secured to an adjacent layer along a weakened interface. The cavitated layer initially conceals certain preprinted indicia, e.g., prize information, but may be subsequently removed by scratching and/or rubbing to allow viewing of such indicia.

Abstract: A flexible film laminate of (a) a polyacrylonitrile film containing a heterized ethylene oxide-propylene oxide copolymer; (b) contacting said film with an adhesive combination layer of a styrene-butadiene block copolymer and a terpolymer of 1,3-pentadiene, a monocyclic terpene and alpha methylstyrene; and (c) a second polyacrylonitrile film or a heat-sealable polyolefin film contacting said adhesive layer; a product pouch made therefrom; and a method of forming said laminate.
