Abstract:
Combined labelling and recycling or reclaiming method including the steps of: forming layered film material containing within itself a separation interface and comprising a hot-stretched coextrudate of two polymeric film plies each formed in the absence of biaxial stretching and each comprising one or more film layers, said film plies being separably adhered to each other at said separation interface and one of them comprising printable in-mold label facestock including a printable face layer, said one of said film plies being further characterized by the absence of any ply-included layer of pressure-sensitive adhesive supporting said printable face layer, the other of said two film plies comprising a heat-activatable adhesive layer that is a contaminant-free recyclable material, printing the facestock with an ink or inks to decorate the same, die-cutting the film material to form individual labels, sequentially deploying the labels for heat activation of the adhesive and bonding onto successive substrates said printing, die-cutting, deploying, and bonding being carried out in the absence of forces at said separation interface sufficient to cause separation, and subsequent to said bonding of said labels to said substrate, imposing separation forces at said interface of said layered film material sufficient to cause inter-ply separation whereby said printed facestock is separated for recycling of said substrate stock uncontaminated by said ink or inks.
