We sell pellets containing antifungal agents and antibacterial agents for the incorporation of olefin-based resins. The applicable resins include polypropylene, polyethylene, and polystyrene. We can also combine them with functional agents upon request. 【Features】 ■ Since granulation is done at low temperatures, there is minimal loss even with organic antibacterial and antifungal agents, allowing for efficient molding. ■ The pellets contain a high concentration of active ingredients, requiring a small amount of formulation and having minimal impact on the material. ■ It is possible to combine multiple antibacterial and antifungal agents. *For more details, please download the PDF or feel free to contact us.

We would like to introduce our manufacturing achievements of "mold and bacteria prevention pellets" for the home goods manufacturing industry. "Mold growth in products used at home negatively affects the product's impression, leading to reduced usage," and "due to the increasing awareness of hygiene, products used at home are required to have antibacterial effects," were the challenges we faced. After implementation, the basic performance of the products has not been compromised, mold growth has decreased, and product deterioration has been reduced, keeping the appearance clean. [Case Overview] ■ The mold and bacteria prevention pellets are mixed and manufactured together during the molding process. *For more details, please download the PDF or feel free to contact us.

We would like to introduce a case where we provided support for the addition of antimicrobial agents to resin products. The plasticizers and additives contained in resin products serve as a nutrient source for bacteria, posing challenges in preventing the appearance and degradation of resin products. Therefore, after explaining the product, we shipped a sample for testing and conducted tests using the prototype. Subsequently, the antimicrobial effect was recognized, leading to its adoption. [Case Overview] ■ Theme: Providing antimicrobial effects ■ Previous specifications: No incorporation of antimicrobial agents ■ Required specifications for solving or improving the problem: Incorporate antimicrobial agents at 0.1% or more ■ Proposed solution: Addition of antimicrobial agents, accommodating small quantities of resin products *For more details, please download the PDF or feel free to contact us.
