PAPER MATERIAL FOR FIBROUS CASING, PRODUCTION METHOD THEREFOR, AND FIBROUS CASING

摘要

The purpose of the present invention is to provide: a paper material for a fibrous casing, said paper material being capable of exhibiting excellent performance in a fibrous casing; a production method therefor; and a fibrous casing in which the paper material for the fibrous casing is used. This paper material for the fibrous casing used as a food packaging material for when foods are to be heat treated is characterized by being formed using pulp as a main component. The paper material for the fibrous casing is further characterized in that one surface thereof is a gloss surface, and another surface thereof is a non-gloss surface. This fibrous casing is characterized by being provided with: a paper layer which is disposed as the innermost layer, and which is formed from a paper material; and a synthetic resin layer which is stacked on the outer surface of the paper layer. The fibrous casing is further characterized in that the paper material is the aforementioned paper material for the fibrous casing. The non-gloss surface of the paper material is preferably disposed so as to be on the inside. Furthermore, the gloss surface of the paper material is preferably disposed so as to be on the inside.
