抗菌剤のみでは充分な抗菌効果が得られない。When an antibacterial agent layer according to the present invention is provided on the inner surface of a wrapping material such as a wrapping paper or a cardboard box, a certain antibacterial agent can be obtained, but a strong antibacterial agent is applied to the inner surface which is in direct contact with food. Cannot be used, and a relatively weak one must be used. However, especially when these packaging materials are left in a highly humid environment, the bacteria do not propagate only on the inner surface of the packaging material, but also propagate in the thickness direction of the material, that is, the outer surface of the paper or inside the paper layer,
This also affects the inner surface. In that case, a sufficient antibacterial effect cannot be obtained only with a normal antibacterial agent.

方のみに塗布すれば良い。At least one outermost layer of the multilayer paper is a layer containing no antimicrobial fiber, and the remaining layer is mixed with antimicrobial fiber. The antimicrobial fiber-containing layer may be the entire remaining layer or a part of the layer. That is, it is sufficient that at least one outermost layer is an antibacterial fiber-free layer, and the other outermost layer may be an antibacterial fiber-containing layer or an antibacterial fiber-free layer. The antimicrobial agent layer is provided on the outermost surface of the antimicrobial fiber-free layer.
When the outermost layer surface of the antimicrobial fiber-free layer is on both sides of the multilayer paper, the antimicrobial agent layer may be provided on both sides, but in practice, when used as a packaging material, It only needs to be applied to only.
