About us
GREAT Biomaterials Co., Ltd.
70 Years of Chemical Manufacturing Expertise
GREAT Biomaterials inherits nearly 70 years of chemical manufacturing experience from AVATACK,
expanding from traditional material development to eco-friendly materials. Founded with a
single and clear mission: solving the environmental crisis caused by plastic pollution.
The team has witnessed firsthand the severe damage traditional plastics have inflicted on the planet
and understands the urgency to take action.
Leveraging solid expertise in formulation design and modification technologies,
we continuously innovate to develop high-performance sustainable materials, opening up a broader green future for our customers.

Custom Modification Technology: Balancing Sustainability & Performance
Guided by the core principle of "environmental responsibility without compromising quality," we specialize in custom polymer modification. From polymer structure adjustments, enhanced weather resistance, and increased impact strength, each step is tailored to customer application needs, ensuring both high-quality performance and sustainability.

Diverse Sustainable Material Development
With extensive experience in blown film, extrusion, and injection molding, we help customers integrate green materials into mass production.
- Recycled: Utilizing post-consumer (PCR) and post-industrial (PIR) recycled materials to create high-performance plastics.
- Biomass: Using agricultural by-products or bio-based raw materials to reduce petrochemical dependence and carbon footprint.
- Compostable: Decomposes into reusable compost under specific conditions, truly enabling a circular economy.

Advanced Pelletizing Equipment: Precision & Stability
Equipped with advanced compounding and pelletizing facilities, we achieve high-purity, consistent material quality. Every stage, from material blending to pelletizing, follows rigorous quality control processes, ensuring high precision and stability, improving production efficiency, and guaranteeing reliable product performance.
Strong R&D Team & TAF-Certified Laboratory
Our team consists of materials scientists, chemical engineers, and analytical application specialists, operating a TAF-certified (Taiwan Accreditation Foundation) laboratory. With rigorous testing processes and scientific data analysis, we ensure compliance with international environmental standards and meet customer needs.
