In recent years, troubles related to the outbreak of mold and bacteria have been occurring in various mining and industrial production activities and in daily life. For example, in production activities in the mining industry, mold and bacteria are generated during the transportation, storage, storage, and use of raw materials and products, which not only deteriorates the raw materials and reduces the functionality of the products, but also significantly deteriorates the appearance of the products. Cases of loss and reduction in product value are occurring frequently. On the other hand, it is well known that even in daily life, there are cases where mold grows on clothing, food, and fixtures, and troubles occur due to the proliferation of bacteria, which hinders daily life.

Various fungicides and antifungal agents have been developed to address these problems, and are sold in various forms such as powder, liquid, and aerosol depending on the purpose, and are used by adding, mixing, or applying them to the target object. . The α-bromocinnamaldehyde used in the present invention was also developed for this purpose and is recognized as a low-toxicity bactericidal and fungicidal agent with excellent bactericidal and antifungal properties. The present inventor has been conducting research to utilize this α-bromocinnamaldehyde in various fields, particularly research into its practical application to films and molded products in the plastics industry.

In general, such bactericides and antifungal agents have a high vapor pressure, and they exhibit their effectiveness by gradually sublimating and dissipating, but α-bromocinnamaldehyde according to the present invention is also compared. Because it is a substance with a low melting point and sublimation property, it can be added to plastics, especially polyolefin films, injection molded products, etc., to impart sterilization and mold-proofing properties. As with ordinary additives such as inhibitors and fillers, if the α-bromocinnamaldehyde is simply blended with these resins, kneaded, extruded or injection molded,
If left for a few days, it will bleed onto the surface of the molded product like powder, not only damaging the hue of the colored molded product, but also staining objects that come into contact with it, and even wasting chemicals. However, it is not possible to obtain truly long-lasting sterilization and anti-mold effects.
