The concealment characteristic layered product which uses the concealment characteristic film and the same film

摘要

Being the concealment characteristic film, it includes with the concealment material and the polyamide resin, degree of concealment is 0.3 or more. The concealment material is the white type concealment material, it is ideal brightness to be 65 - 100%. As an example, as titanium oxide is included 5 - 40 mass %, 60 - 95 mass % the film which is included can list the polyamide resin. The concealment characteristic layered product, at barrier resin layer and the concealment characteristic film polyamide resin layer and the sealant layer which are formed has the layer of 3 types at least. As for the concealment characteristic layered product, degree of concealment is 0.3 or more, oxygen permeability 100ml/(m day MPa) is below.
