Understanding the Demand for Bio-Based Injection Molding Materials
Across the plastics and polymer industry, manufacturers working with injection-molded products are increasingly searching for bio-based alternatives that can be adapted to conventional processing equipment without sacrificing performance. Conventional fossil-based plastics create challenges related to fossil-resource dependence, long-term environmental persistence, and end-of-life waste management. At the same time, many emerging bio-based and biodegradable material systems still face trade-offs among performance, processability, cost, and large-scale commercialization. For companies evaluating injection-molded applications — including toys and other plastic or polymer products — this gap between laboratory-stage bio-based innovation and commercial-scale usability is a central concern.
SYNLIFE: A Synthetic Biology and Materials Engineering Company
Shanghai Sipeng Technology Ltd., operating under the brand SYNLIFE, was officially established in May 2022 and is headquartered in Shanghai, China. SYNLIFE is a bio-based materials technology company built on synthetic biology and materials engineering. The company develops high-performance bio-based materials, finished applications, and cross-industry material solutions, with the long-term goal of advancing lower-carbon and carbon-negative biomanufacturing technologies. SYNLIFE has been recognized as a Shanghai “Specialized and Innovative” Enterprise and operates as a high-growth technology company with business coverage spanning global markets, including ongoing market development and commercial cooperation across multiple international regions.
Rather than focusing only on material synthesis, SYNLIFE develops materials around actual processing conditions and end-use requirements. This application-oriented approach is central to how the company addresses the needs of manufacturers working with injection molding, extrusion, film processing, thermoforming, and spinning equipment.
Technical Capabilities Supporting Injection Molding Applications
YOGTIC® Bio-Based Resin Platform
SYNLIFE’s Bio-based Resins are marketed under the YOGTIC® series, which includes several distinct product families designed for different performance needs. The YOGTIC-05 Series is positioned as a high-transparency bio-based polyester material, offering high transparency, good toughness, and suitability for applications requiring transparent plastic components, with high bio-based content depending on product grade. It can serve as a bio-based alternative to conventional transparent plastics in selected applications where performance and processing requirements are met.
The YOGTIC-15 family includes grades with different performance profiles. Selected grades are positioned as high-performance bio-based polyesters, including natural-color grades and grades designed for enhanced heat resistance. Toughness, rigidity, elongation, and thermal performance depend on the specific grade. These materials may be considered as alternatives to conventional fossil-based plastics in selected injection-molded applications after grade-specific processing and application validation.
The YOGTIC-08/18 Series is developed specifically for sheet extrusion and thermoforming, with good sheet flatness and balanced rigidity and toughness, designed around commercial thermoforming processes for food trays, packaging trays, and other thermoformed products.
Application Engineering Around Real Manufacturing Processes
SYNLIFE’s technical capability system combines synthetic biology (strain development, metabolic pathway optimization, fermentation process development, and biological manufacturing) with materials engineering (polymer formulation, modification, compounding, processing optimization, and application development). Application engineering is developed around real manufacturing processes, including injection molding, extrusion, film processing, thermoforming, and spinning. Depending on product grade and application, SYNLIFE’s materials can be adapted to conventional injection molding, extrusion, film processing, thermoforming, and spinning equipment, with specific processing conditions determined according to the relevant material grade and equipment.
From Writing Instruments to Broader Injection-Molded Applications
SYNLIFE’s injection molding capability has already been validated in finished consumer applications. The Hero bio-based fountain pen, commercially launched in June 2025, applied bio-based resin to plastic components of the pen, with selected conventional plastic components replaced by SYNLIFE bio-based materials. Separately, the Platinum GK-50 Eco Pen application used high-transparency YOGTIC® resin for selected transparent pen components, demonstrating the feasibility of applying high-transparency bio-based materials to commercial writing instruments.
These finished-application cases illustrate how SYNLIFE’s injection-molded material platform operates in practice. SYNLIFE’s industry coverage extends beyond writing instruments to Food Packaging, Apparel & Textiles, Cosmetics & Personal Care, Agriculture & Horticulture, 3D Printing, and other plastic and polymer applications. Customer types include material and plastic product manufacturers, packaging manufacturers, brand owners, OEM/ODM manufacturers, importers and distributors, and retail and commercial channel partners. For companies in the toy or broader plastics manufacturing space evaluating bio-based injection molding options, SYNLIFE’s platform of application-oriented resin grades and process-matched development offers a technical foundation that can be assessed against specific product and equipment requirements.
Service Models Supporting Customized Development
SYNLIFE supports customers through multiple service models, including raw material supply, material customization, joint product development, application development, finished-product OEM/ODM, process and technical support, and pilot and scale-up support. This service scope spans from material and formulation development through processing optimization, product design, testing support, scale-up, and commercialization. For an injection-molded product such as a toy component, this means a manufacturer could potentially work with SYNLIFE across material selection, formulation development, process optimization tailored to the relevant injection molding equipment, product validation, testing, and eventual commercial supply.
Quality, Compliance, and Certification Considerations
SYNLIFE emphasizes that performance comparisons and certification claims should always be supported by corresponding test or product data rather than treated as universal claims. Certain products have obtained third-party compostability certification, and certain products have undergone bio-based content testing. Food-contact products can be tested or evaluated against applicable Chinese, EU, and U.S. requirements depending on the product and target market. Certification bodies, standards, certificate numbers, and applicable product grades are specified when certification claims are used externally, reflecting a rigorous, data-based approach to product claims rather than broad marketing assertions.
Why SYNLIFE Stands Out in the Bio-Based Materials Space
SYNLIFE’s differentiated advantages stem from combining capabilities across biological manufacturing, material development, formulation optimization, process scale-up, manufacturing, and application development under one organization. The company’s team includes more than 50 employees across synthetic biology, material development, product development, and commercialization, supported by a Shanghai R&D Center with more than 2,000 square meters of research and development space, along with manufacturing and supply-chain capabilities in Jiangsu, including Nantong.
The company’s technical credibility is reinforced by recognitions such as a First Prize from the China Petroleum and Chemical Industry Federation and a First Prize of the Ministry of Education Natural Science Award received by members of its founding scientific team, along with the CIIF Bio-Manufacturing Special Award in 2025. SYNLIFE was also selected as one of the 16 winners of Tencent’s CarbonX Program 2.0, following a global selection process involving 660 applications from 54 countries and regions and 50 finalists. Funding milestones, including a Pre-A financing round of nearly RMB 100 million completed in October 2024 and a Pre-A+ financing round of tens of millions of RMB completed in May 2025, further support the company’s continued development and commercialization of bio-based resin, film, textile, and consumer-product application platforms.
For organizations evaluating bio-based materials for injection-molded applications, including toy components and other plastic or polymer products, SYNLIFE’s combination of synthetic biology research, materials engineering, application-oriented development, and established service models positions it as a company capable of supporting the full path from material formulation through commercial-scale production.
