Abstract
Description
technical field
[0001] The present invention relates to a novel laminate manufacturing method and coextruded sheet.
[0002] Specifically, the present invention relates to a laminate having a structure in which a polycarbonate layer, an adhesive layer containing an adhesive composition, and preferably a layer containing a resin other than polycarbonate such as polyolefin are laminated. Manufacturing method of body and coextruded sheet. Background technique
[0003] Polycarbonate is used in various applications in many fields due to its excellent transparency, gloss, heat resistance, impact resistance, and ease of mass production. Further, by multilayering polycarbonate and other materials, it is possible to combine advantageous properties of other materials. For example, as a cladding material characterized by the luster of polycarbonate, polyolefin having better heat-sealability than polycarbonate is laminated on polycarbonate to achieve both luster and heat-sealability o...
