Base paper for metallized paper, metallized paper, and packaging bag

Abstract

Provided are: base paper for vapor deposition paper, which has excellent printability and excellent processing suitability in automatic packaging; and vapor deposition paper formed using the base paper. The base paper for vapor deposition paper has a resin layer on one surface of a paper substrate and is for forming a vapor deposition layer on the resin layer, in which the base paper for vapor deposition paper has a pigment coating layer on the other surface of the paper substrate, a content of a pigment in the pigment coating layer is 50% by mass or more and 85% by mass or less, and the surface having the pigment coating layer has an Oken type smoothness of 300 seconds or more and a coefficient of kinetic friction against stainless steel of 0.35 or less. The vapor deposition paper has a vapor deposition layer on a resin layer of a base paper for the vapor deposition paper having the resin layer on one surface of a paper substrate and a pigment coating layer on the other surface of the paper substrate, in which a content of a pigment in the pigment coating layer is 50% by mass or more and 85% by mass or less, and the surface having the pigment coating layer has an Oken type smoothness of 300 seconds or more and a coefficient of kinetic friction against stainless steel of 0.35 or less.
