In the plastic industry, there is a demand for improved material rigidity to enhance the strength and durability of products. This is particularly important in applications such as automotive parts and construction materials, where high mechanical performance is required, as it is crucial to minimize material deflection and maintain shape. A lack of rigidity can lead to product damage or performance degradation. The talc we provide has properties that contribute to the improvement of plastic rigidity. 【Application Scenarios】 - General rigidity enhancement of plastic products - Additive for automotive parts - Application in construction materials 【Effects of Implementation】 - Improvement of product mechanical strength - Enhancement of shape stability - Increased product durability

We would like to introduce a case where "film and sheet bio-material pellets" were produced using 100% biomass resin (bioplastics). By incorporating 51% mineral filler, we can mold thin sheets with a thickness of 0.04 to 0.05 mm, achieving a departure from 100% petroleum-derived materials. Additionally, by combining this resin with biodegradable resin, we can accommodate a variety of applications. We assist brand owners in realizing their sustainability efforts (such as reducing petroleum-derived resins and CO2 emissions) and in communicating information on reducing environmental impact through material substitution in waste disposal scenarios. 【Case Overview】 ■ Usage scenarios: Multi-sheets and garbage bags disposed of as waste in agricultural settings, or packaging sheets for gift plastic materials. ■ Industries: Agriculture, garbage bag industry, gift packaging industry, etc. *For more details, please download the PDF or feel free to contact us.

• Biodegradable plastics

We would like to introduce a case study where "cutlery/tableware bio-material pellets" were produced using 100% biomass resin (bioplastic). By incorporating 80% high concentration of oyster shell powder and wood powder, and combining the resin with bio-materials, we achieved a 100% bio-material (excluding additives) that is environmentally friendly and suitable for injection molding. We assist brand owners in realizing their sustainability efforts (such as reducing petroleum-derived resins and CO2 emissions) and in communicating information on reducing environmental impact through food-related settings by replacing materials. 【Case Overview】 ■ Usage scenarios: Disposable situations or repeated use scenarios for spoons, forks, chopsticks, tableware, etc. ■ Industries involved: Convenience store industry, event industry, school lunch industry, etc. *For more details, please download the PDF or feel free to contact us.

• Biodegradable plastics

We would like to introduce a case study of the production of "bio-material pellets for liquid bottles" using 100% biomass resin (bioplastics). By blending 80% high-concentration powder from oyster shells and wood powder, and combining it with bio-material resin, we achieved a 100% bio-material (excluding additives) that is suitable for blow molding, making it an environmentally friendly material. We assist brand owners in their sustainability efforts (reducing petroleum-based resins, reducing CO2 emissions, etc.) and help communicate information on reducing environmental impact through the replacement of materials in everyday life. 【Case Overview】 ■ Usage scenarios: Bottles for detergents, liquid soaps, shampoos, conditioners, etc. ■ Industries: Toiletries industry, shampoo industry, etc. *For more details, please download the PDF or feel free to contact us.
