  • Publication number: 20090104441
    Abstract: The object of the present invention is to provide a laminated sheet for thermoforming, including a thermoplastic resin film layer; a decoration layer; and a support base resin layer, wherein the thermoplastic resin film layer, the decoration layer, and the support base resin layer are sequentially laminated, and the support base resin layer contains one or more linear low density polyethylene layers. Also, the object of the resent invention is to provide a formed product obtained by thermoforming the laminated sheet, and a method of producing the same. Furthermore, the object of the present invention is to provide an injection-molded product obtained by loading an injection resin onto the backside of the molded product, and a method of producing the same.

  • Patent number: 6248430
    Abstract: The present invention provides a lactic acid-based polymer laminated product which is little liable to leakage of lactide during molding or storage of the molded product and can degrade at a raised rate and a molded product made of such a laminated product. Disclosed are a novel lactic acid-based polymer laminated product comprising a degradation accelerator barrier layer (II) made of a lactic acid-based polymer (B) having a lactide content of not more than 0.1% by weight laminated on one or both surfaces of a base layer (I) made of a lactic acid-based polymer (A) comprising a degradation accelerator made of lactide and/or organic acid in an amount of from 0.3 to 7% by weight, wherein the ratio of the barrier layer thickness to the base layer thickness is from 0.02 to 1 based on that of the base layer, and a molded product of the laminated product.
