Bio-resin for film and sheet (with oyster shell powder)

[Sample available] Achieving bio (oyster shell powder or cellulose over 51%). Contributing to efforts to reduce petroleum-derived resins and decarbonization!

Our company offers high-concentration bioplastics made from a combination of plant-derived resins such as corn, plant-derived fillers like wood powder, bamboo, cellulose, and paper powder, as well as natural fillers like oyster shell powder, with over 51% and up to 80% of these components. Utilizing over 20 years of cultivated high technical capabilities, we blend and compound various raw materials in high concentrations. Through the provision of lightweight, durable, and tough high-performance bioplastic pellets, we contribute to the reduction of petroleum-derived resins and the environmental burden reduction aimed at CO2 reduction and decarbonization. 【Features】 ■ High-concentration bioplastic pellets (petroleum-derived resin or natural resin + natural filler 51%) ■ Filler concentration can be accommodated up to 80% ■ Compatible with biodegradable resins ■ Usable in various products such as environmentally friendly container packaging materials, films, and sheets ■ Provided in pellets blended with domestic and international biomass raw materials ■ Combinations with natural fillers such as oyster shell powder, cellulose, talc, clay, etc., are also possible *Samples are available at the High-Performance Materials Week. *For more details about the products, please refer to the materials. Feel free to contact us with any inquiries.

We will be exhibiting at the High-Performance Materials Week [Tokyo Exhibition]!

  • SEMINAR_EVENT

■PR Points Aiming for the realization of a decarbonized society, a sustainable society, and the reduction of environmental impact, we present "Future Materials Born from the Blessings of Forests and Oceans," featuring masterbatches made from cellulose (CNF, CMF) + oyster shell powder + recycled resin, among others. Our booth also displays physical property data categorized by general grade, home appliance grade, and automotive grade. ■Business Description Through the development of environmentally friendly materials, we are addressing social issues from the perspective of materials. Utilizing our unique technology of high-concentration filler blending, we can create plastic materials using eco-friendly raw materials. We primarily use plant-based fillers (cellulose nanofibers, cellulose microfibers, wood powder, etc.), natural minerals (talc, clay, calcium carbonate, mica, etc.), and natural resources (oyster shells, etc.) as fillers, blending them with various resins (biodegradable, plant-based, fossil resource-based) to provide high-concentration biomass compounds and masterbatches through various combinations. Here is an article about our initiatives: https://www.ipros.jp/catalog/detail/777405
