ように、シヨーケースを通気性のあるカーテンで
覆うことが望ましい。 Recently, in department stores, supermarkets, etc., fresh foods, vegetables, frozen foods, beverages, etc. are often sold in open-type frozen or refrigerated cases. However, during closing hours, it is necessary to keep the above-mentioned store case warm in order to prevent waste of refrigeration energy. In this case, if the case is completely sealed, there is a problem in that the odor gets stuck inside the case and the products inside the case have a smell peculiar to refrigeration. Therefore, it is desirable to cover the show case with a breathable curtain to ensure a certain degree of ventilation to the outside inside the show case.

めにブロツキングしたりする不具合がある。 However, breathable curtains usually have good water permeability, so if the air in contact with the curtain surface (air outside the curtain case) is cooled and the moisture in that air condenses on the curtain surface, this will occur. Condensed water passes through the curtain and drips into the show case, causing problems such as products in the show case becoming defective or blocking due to freezing.

For 2, woven fabric, knitted fabric, non-woven fabric, mesh, felt, etc. can be used. The above partial adhesion is net-like,
The bonding may be done in any form such as waves, spots, or streaks, and the bonding area is 20 to 80% of the total area (area of the polytetrafluoroethylene porous film or reinforcing material).

回避できる。 As mentioned above, the heat-insulating curtain for refrigeration and cooling case cases according to the present invention can be suitably used for keeping open-type refrigeration or cooling case cases warm during closing hours, etc., and is breathable, allowing ventilation inside the case case. Since the odor can be maintained sufficiently, it is possible to prevent the above-mentioned odor from adhering to the products in the show case. In addition, even if moisture in the air that contacts the top surface of the curtain condenses, the polytetrafluoroethylene porous film is water-repellent, so it can effectively prevent the condensed water from penetrating the curtain. It is possible to sufficiently avoid dripping of dew condensed water onto the surface of the container, thereby preventing product defects and freeze blocking in such cases.
勿論、通気性補強材のために機械的強度にも秀
れている。 Of course, it also has excellent mechanical strength because it is a breathable reinforcing material.
