Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pressure-sensitive adhesive tape for packaging provided with antibacterial and insect repellent properties.

[0002]

2. Description of the Related Art A pressure-sensitive adhesive tape for packaging is also called, for example, a gum tape and has a pressure-sensitive adhesive layer provided on one surface of a base material such as paper or cloth, and a release agent layer provided on the other surface. No consideration was given to antibacterial and insect repellent.

[0003]

As described above, the conventional adhesive tape for packaging has no consideration given to the antibacterial and insect repellents, and thus has an antibacterial and insect repellent effect inside and / or outside a storage case such as a cardboard box. It is used to fix the folded part when assembling the cardboard box, which is a storage case, even if the antibacterial insect repellent effect is expected by applying or spraying a chemical with an antibacterial insecticide storage case Since adhesive tapes that do not have any antibacterial and insecticidal effects are used, no invasion of large insects can be eliminated, but no measures are taken against invasion of harmful bacteria. However, it was impossible to prevent harmful bacteria from entering the area. In view of these points, an object of the present invention is to provide a pressure-sensitive adhesive tape for packaging that can exhibit an antibacterial insect repellent effect even from the position of the pressure-sensitive adhesive tape used for assembly in a storage case assembled using the pressure-sensitive adhesive tape. I do.

And a release layer 5 composed of

In the present invention, the organic antibacterial insecticide A
Although the medicinal effect is remarkably excellent, it has the property of being easily volatilized, whereas the inorganic antibacterial agent B has a slightly lower medicinal effect than the organic antibacterial insecticide A, but its volatilization is smaller than that of the organic antibacterial insecticide A. The antibacterial insecticide layer C, which has high medicinal properties and excellent durability, is formed by using the organic antibacterial insecticide A and the inorganic antibacterial agent B in combination because of its slow volatilization and excellent sustainability. It became. In particular, when the organic antibacterial insecticide A is filled in the porous microcapsules, the antibacterial insecticide layer C having more excellent durability is formed.

The hinokitiol used in the present invention contributes to antibacterial activity and insect repellency. Among them, the bacteria include Staphylococcus aureus, Streptococcus, Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae, Aspergillus, Yeast, Bacillus subtilis, Welsh The Aomori Prefectural Industrial Research Institute has announced that it is effective against bacteria, Proteus bacteria, freesia-derived bacteria, strawberry-derived bacteria, etc., and home services that are effective against insects such as Dermatophagoides farinae, cockroaches, and ants. Biological Research Institute, Inc. has published in the report. In addition, it has been recognized that plant extract components such as genoshoko, sasa, mugwort and the like have an effect on Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli and the like.
