<p>PURPOSE:To improve mechanical strength and resistance against chemical by providing a resin layer having resistance against chemical on the inner side. CONSTITUTION:A plastic layer 1 having resistance against chemical on the inner side of a container base 2a to constitute a multilayered container. As the resin to be used having resistance against chemical, such resin that it is resistant to specific chemical, for example, high nitrile resin, polyester resin, polyether etherketone resin, etc. generally having resistance against chemical can be used. High nitrile resin refers to copolymer mainly comprising unsaturated nitrile monometricsubstance such as acrylonitrile and metacrylonitrile wherein 50 wt.% or more of unsaturated nitrile monometric substance is contained. Thus a container with high strength and resistant against various chemicals can be obtained at low cost without using a large amount of expensive materials.</p> |
