Description

  The present invention relates to an insect-proof film or sheet.

Conventionally, there is a desire to prevent small animals, insects, etc. (hereinafter also referred to as pests) from entering into various objects such as buildings, various containers, and various devices.
Insect repellent measures include, for example, a method of distributing insect pests and insecticides at the entrance and route of pests to an object, and pest nesting sites. However, in this method, there is a concern that insecticides and insecticides are scattered and the surrounding environment is contaminated, and in the case of a long period of time, there is a concern that the insect repellent effect is weakened and a pest is allowed to enter the object.

  On the other hand, an insect repellent sheet containing an insect repellent active ingredient that is used to prevent the invasion of pests or to eliminate pests is known. In this insect repellent sheet, since the insect repellent active ingredient contained in the molded body gradually moves to the sheet surface, it is said that the insect repellent and insecticidal action can be sustained for a long time against pests. Further, since no insect repellent or insecticide is distributed, it is possible to suppress contamination of the surrounding environment.

  As a technique regarding such an insect repellent sheet, for example, one described in Patent Document 1 (Japanese Patent Laid-Open No. 2010-285417) can be cited.

  Patent Document 1 discloses a laminated sheet-like product having a drug-containing resin layer between two layers of the same or different types, wherein the drug-containing resin layer has a vapor pressure of 0.001 Pa or more at 25 ° C. A mixture obtained by mixing a pyrethroid drug and a hot melt resin containing an ethylene copolymer resin, a synthetic rubber resin, or both at a mass mixing ratio of 5:95 to 50:50, and liquefying the mixture by heating. By laminating the other sheet layer on the sheet layer, the drug-containing resin layer is fixed at room temperature by being sandwiched between the two sheet layers. There is described a pest repellent laminated sheet-like material that has a shape and at least one of the sheet layers is a drug-permeable sheet layer that is permeable to the pyrethroid drug.
