PURPOSE:To obtain the liquid chemical transporting tube which can be securely joined to a liquid chemical container made of an ethylene/vinyl acetate copolymer(EVA) by providing the tube with an unplasticized soft polyvinyl chloride layer contg. a vinyl chloride resin and an ethylene/carbon monoxide/ alkyl (meth)acrylate copolymer. CONSTITUTION:This liquid chemical transporting tube is formed by laminating an olefin/vinyl ester copolymer layer 13 via an adhesive layer 12 on the unplasticized soft PVC(polyvinyl chloride) layer 11. The unplasticized soft PVC layer 11 is the compsn. consisting of the vinyl chloride resin and the ethylene/ carbon monoxide/alkyl (meth)acrylate copolymer. The materials for the adhesive layer 12 include the ethylene/vinyl acetate copolymer, chlorinated polyethylene, etc. The olefin/vinyl ester copolymer layer 13 is constituted of, for example, an ethylene/vinyl acetate copolymer. Since this liquid chemical transporting tube has the unplasticized soft PVC layer contg. the vinyl chloride resin and the ethylene/carbon monoxide/alkyl (meth)acrylate copolymer, the liquid chemical container made of the EVA and the unplasticized soft PVC layer can be securely adhered. |
