<p>PURPOSE: To obtain a laminated material which has good interlayer adhesion and can be separated into individual constituents promptly after being used in a packaging field and others by forming a peeling layer of a steam-soluble, water-soluble, or water-dispersible organic material at least on one side of a thermoplastic resin layer. CONSTITUTION: In a laminated material including at least one layer 1 of a thermoplastic resin having latent intrinsic separation capacity, the layer 1 has a peeling layer 2 of a steam-soluble, water-soluble, or water-dispersible organic material such as a water-soluble polyvinyl acetate at least on one side. The thickness of the peeling layer 2 is 0.001-5.0μm. For example, a base material film 1, the peeling layer 2, a separation layer 3, a primer 4, a decorative layer 5, and an adhesive layer 6 are provided for constitution. As a result, after the use in a packaging field or for a blocking film and others, individual constituents can be separated promptly by a simple means.</p> |
