製造する方法に関する。[Detailed Description of the Invention] [Field of Industrial Application] This invention is a method of spraying or arranging a powdery vaporizable agent such as a rust preventive agent, a fungicide, or a flavoring agent on paper. To manufacture a packaging material having excellent medicinal efficacy, which integrates a synthetic resin, a vaporizable drug, and paper, and which is characterized by embedding and fixing the drug by extrusion coating of a synthetic resin having barrier properties against the drug. Regarding the method.

Many packaging materials have been known that have anti-corrosion, anti-mold, and fragrance effects through the use of powdery, volatile chemicals such as anti-corrosion agents, anti-fungal agents, and fragrance agents. . For example, (1) paper or film impregnated with or coated with a solution of the above-mentioned powdery vaporizable drugs; (2) film made by mixing and kneading the above-mentioned powdery vaporizable drugs with a thermoplastic synthetic resin. (3) There is a laminated sheet made by interposing the powdery vaporizable drug layer between laminated paper and a synthetic resin film and press-bonding them together.

られるために気化性薬剤の気化性が悪くなる。 However, in (1), paper impregnated with or coated with a solution of a powdery vaporizable drug generally vaporizes quickly from both the front and back sides, so when using the paper, kraft paper or polyethylene It becomes necessary to wrap the product in additional film, which not only increases packaging costs but also reduces work efficiency. In addition, the method of applying or impregnating a solution of a powdery vaporizable chemical after film forming requires complicated steps and requires additional equipment for removing the solvent, which is economically disadvantageous. The film (2) has drawbacks such as the vaporizable drug seeping out on both sides, resulting in a large amount of drug loss, and the drug efficacy on the inner surface of the film, which is necessary as a packaging material, being halved. The laminated sheet (3) is a much more efficient packaging material than the above (1) and (2), but it is expensive because it is made by pressing pre-laminated processed paper. However, since the air permeability of the paper is impeded by the laminate layer, the vaporization of vaporizable chemicals becomes poor.

れた包装材８を得る。 FIG. 1 shows an example of a process diagram of the method for producing a packaging material of the present invention. Paper 1 is fed at a desired speed and introduced onto a belt conveyor 4, and a required amount of vaporizable chemical 2 is dropped onto the paper 1 from a hopper.
For example, by providing a hopper with a large number of outlets spaced apart in parallel, the vaporizable chemical 2 is dispersed onto the paper 1 in a strip shape, and by intermittent dropping from the hopper, the vaporizable chemical 2 is dispersed at intervals in the direction in which the conveyor travels. be scattered. Further, the vaporizable chemicals spread widely can also be arranged in a band shape using the comb teeth 5. By dispersing or arranging the vaporizable chemicals in this manner, the desired seal portion 9 is formed in a band-like or lattice-like form.
Next, the molten resin 3 discharged from the extruder is introduced into the guide roll 6 and laminated, and the vaporizable agent 2 is buried and fixed while being pressed with the pinch roll 7. At the same time, the paper 1 and the molten resin 3 are bonded to the sealing part 9. A packaging material 8 in which a synthetic resin, a vaporizable drug, and paper are integrated is obtained.

ることもない。 The packaging material obtained by the method of this invention has much better permeability to vaporizable drugs than synthetic resin film.
Using breathable paper, the paper and drug are brought into direct contact, and the drug is fixed to the paper using a synthetic resin that has barrier properties against vaporizable drugs. is remarkable, and its effect is fast-acting. Furthermore, as the powder and granules of the vaporizable drug are embedded and fixed in the resin, the resin and paper are firmly bonded through the sealing part, so the vaporizable drug is not likely to peel off or fall off due to external forces such as frictional vibrations. do not have.
