LIGHT SCREENING PAPER

摘要

PROBLEM TO BE SOLVED: To obtain a recyclable light screening paper for food capable of using a metal detector at a stage of shipping of packed material of article by dissociation regeneration as waste paper after the use of the light screening paper. SOLUTION: In this dissociable and regenerative light screening paper obtained by providing a paper base with a light screening layer consisting essentially of a colored pigment, the light screening paper for food has >=1×108Ωsurface electrical resistance value on the surface of the light screening layer measured by 100 V impressed voltage, can detect a foreign matter of metal admixed in contents and is regenerative.
