順調な生育を促進するのに用いられる。[Prior Art and Problems to be Solved by the Invention] Fruit paper is generally used in the form of a bag, and this bag is placed over the fruit at the early stage of fruit growth to remove the fruit, such as pears, apples, grapes, etc. It is used to protect fruits from pests and diseases, and at the same time to promote the smooth growth of fruits by transmitting a moderate amount of ultraviolet rays.

問題がある、(3)接着力が強すぎて果実が接着剤で
汚染される、(4)コストが高くなる。 When making a fruit bag, fruit paper is shaped into a bag, and the periphery of the bag other than the opening is pasted with adhesive. In this case, the specially treated water-repellent paper mentioned above is
Since it is difficult to uniformly apply water-based resin adhesives, conventionally solvent-based resin adhesives have had to be used. However, the use of solvent-based resin adhesives has the following drawbacks. In other words, (1) solvents dissolve specially processed impregnating ingredients, which adversely affects the transmission of ultraviolet rays, which is bad for fruit growth; and (2) safety, hygiene, and toxicity issues caused by solvents. (3) The adhesive force is too strong and the fruit is contaminated with the adhesive; (4) The cost is high.

い。 In addition, as a conventionally known water-based emulsion type adhesive for water-repellent paper, for example, there is JP-A No. 53-91940, but this is an emulsion whose main component is an ethylene-vinyl acetate copolymer, and this emulsion alone cannot be used. The wax paper which is the object of the present invention cannot be laminated at all. Furthermore, a water-repellent cardboard adhesive containing vinyl acetate emulsion and acrylic-styrene copolymer latex as essential components is disclosed in JP-A-58-98239, but this adhesive requires heat treatment during lamination. and cannot be bonded at room temperature.

悪影響は全く認められなかつた。Natural rubber latex (concentration 50%) 30 parts Styrene-butadiene latex (concentration 50%) 10 Casein 0.5 Rosin 15 Xylene 15 Dibutyl phthalate 5 Ammonia water (25%) 0.1 Water 24.4 Total 100 parts [Adhesion test and application to fruit] Effect Test] The adhesives obtained in Examples 1, 2, and 3 above were applied to the surface of wax paper for pear bags using an applicator.
The coating amount was 30 to 40 μm (dry). Immediately after coating, it was overlapped with the back side of wax paper and pressed with a rubber roller. This was left to dry at 20°C x 65% RH for 24 hours, and then a peel test was conducted. As a result, the wax paper adhered with the above adhesive was not peeled off by the adhesive layer and the wax paper was torn. Further, no dissolution of the resin content of the wax paper was observed, and no adverse effects on the fruit were observed at all.

果実の生育が阻害された。 In the case of only the emulsion adhesive (1), it peeled off on the adhesive surface of the wax paper and could not be used. In the case of the solvent-based adhesive (2), the adhesive strength is strong enough to tear the wax paper as in the present invention, but the resin content on the surface of the wax paper dissolves and the light of this dissolved part The transmittance increased and stains appeared on the fruit surface. Furthermore, with solvent-based adhesives,
The resin content of the wax paper seeped into the inside of the wax paper bag along with the solvent and came into contact with the fruit surface, inhibiting fruit growth in that area.
