Embodiment 1

[0069] First, 30 g of an antifungal agent (Sanjin Co., Ltd. SAN-N-DS (organic antibacterial agent) manufactured by Printing Co., Ltd.) was prepared to prepare a printing ink containing 2.9% by mass of an antifungal agent. In addition, as a substrate sheet, a polyethylene film (HDPE) of 1000 cm x 3000 m was prepared.

[0070] Next, the above-mentioned printing ink was set on a gravure printing machine, and the above-mentioned substrate sheet was subjected to full-surface solid printing with a part of hollow characters ("Anti-mold MADE IN JAPAN"). In addition, the depth (plate depth) of the recessed part of the plate cylinder (gravure plate) installed in the gravure printing machine was 18 micrometers. Operate as above to make anti-mildew sheets. In addition, the total area of ​​the printing area obtained by using the printing ink was 98% of the whole area of ​​a base material sheet.

Embodiment 2

[0087] [Example 2, Comparative Example 2]

[0088] First, 30 g of an antifungal agent (manufactured by Sanjinsha Printing Co., Ltd., SAN- N-DS (organic antibacterial agent)) prepared a printing ink containing 2.9% by mass of an antifungal agent. Moreover, the polyethylene film (LDPE) of 50 mm x 50 mm x 0.02 mm (thickness) was prepared as a base material sheet.

[0089] Next, the above-mentioned printing ink was placed on a gravure printing machine, and the above-mentioned substrate sheet was subjected to full-face solid printing with a part of hollow characters ("Anti-mold MADE IN JAPAN"). In addition, the depth of the recessed part of the plate cylinder (gravure plate) provided in the gravure printing machine was 20 micrometers. Operate as above to make anti-mildew sheets. In addition, the total area of ​​the printing area obtained by using the printing ink was 98% of the whole area of ​​a base material sheet.

[0090] The evaluation test was performed in accordance with ...

Embodiment 3

[0095] First, 30 g of an antifungal agent (manufactured by Sanjinsha Printing Co., Ltd., SAN- N-DS (organic antibacterial agent)) prepared a printing ink containing 2.9% by mass of an antifungal agent. Moreover, the polyethylene film (LDPE) of 100 mm x 100 mm x 0.03 mm (thickness) was prepared as a base material sheet.

[0096]Next, the above-mentioned printing ink was set on a gravure printing machine, and the above-mentioned base material sheet was printed in the same manner as in Example 1. Among them, a plate cylinder (gravure plate) installed on a gravure printing machine used a gravure plate having a depth of recesses (plate depth) of 20 μm. Operate as above to make anti-mildew sheets. In addition, the total area of ​​the printing area obtained by using the printing ink was 98% of the whole area of ​​a base material sheet.

Abstract

This method for manufacturing a mildewproof sheet comprises: a step A of preparing a printing ink containing a mildewcide, and a base material sheet; and a step B of printing the base material sheet with at least one of a character, a graphic, and a pattern by intaglio printing using the printing ink. This packaging material comprises a mildewproof sheet in which at least one of a character, a graphic, and a pattern is printed on a surface of a base material sheet using a printing ink containing a mildewcide.

Description

technical field [0001] The present invention relates to a manufacturing method and packaging material of an anti-mold sheet capable of suppressing mold. Background technique [0002] In recent years, most of the daily necessities, furniture, or clothing items such as suits, shoes, and accessories distributed in Japan have been produced abroad, and imported to Japan after being produced abroad. Most of these clothing items are imported from Southeast Asian countries, but since the climate in these regions tends to be hot and humid, there is a problem in storage. That is, clothing items are imported from Southeast Asian countries to the country and are basically transported by sea, and the transportation takes about one month. During this period, the clothing items are kept in containers. In addition, due to the high-temperature and high-humidity environment in the container, clothing items may become moldy, and there are problems such as loss of value as a commodity. [000...
