Understanding the Food Tray Material Challenge

Food tray manufacturers, brand owners, and packaging converters are increasingly asking a practical question: what material can deliver the sheet flatness, rigidity, and toughness required for thermoformed food trays while also addressing the fossil-resource dependence, environmental persistence, and end-of-life waste issues associated with conventional fossil-based plastics? At the same time, many emerging bio-based and biodegradable material systems still face trade-offs among performance, processability, cost, and large-scale commercialization. This is precisely the industry pain point that SYNLIFE, the brand operated by Shanghai SiPeng Technology Co., Ltd., was built to address.

Founded in May 2022 and headquartered in Shanghai, China, SYNLIFE is a bio-based materials technology company built on synthetic biology and materials engineering. Rather than focusing only on material synthesis, the company develops materials around actual processing conditions and end-use requirements — an application-oriented approach that is directly relevant to a category as processing-sensitive as food trays.

SYNLIFE’s Bio-Based Resin Platform for Food Trays

SYNLIFE’s answer to the food tray material question sits within its YOGTIC® bio-based resin series, a product line developed specifically to bridge the gap between laboratory-stage bio-based innovation and commercial-scale applications.

YOGTIC-08 / 18 Thermoforming Series

Within the YOGTIC® family, the YOGTIC-08 / 18 Thermoforming Series is positioned specifically as a bio-based material developed for sheet extrusion and thermoforming — the exact manufacturing process used to produce food trays. Its key features include:

 

• Good sheet flatness, which supports consistent thermoforming outcomes
• Balanced rigidity and toughness, allowing the material to hold shape under load while resisting cracking or deformation
• A design built around commercial thermoforming processes, with specific processing conditions determined according to the relevant product grade, equipment, and application

According to SYNLIFE’s product positioning, this series is intended for food trays, packaging trays, and other thermoformed products, making it the most directly relevant option within the company’s portfolio for tray-specific applications.

Complementary Options: YOGTIC-05 and YOGTIC-15 Series

Within the broader YOGTIC® platform, SYNLIFE also offers two additional resin series designed for different performance and processing requirements:

• YOGTIC-05 Series: A high-transparency bio-based polyester material offering high transparency, good toughness, and high bio-based content depending on product grade. This series is suited to applications requiring transparent plastic components, and can serve as a bio-based alternative to conventional transparent plastics where performance and processing requirements are met.
• YOGTIC-15 Series: A high-performance, natural-color bio-based polyester material with improved thermal resistance compared with conventional PLA grades, along with balanced toughness and rigidity. This series is suitable for selected injection-molded and rigid applications, providing an option for replacing conventional fossil-based plastics after appropriate application validation.

Together, these platforms illustrate SYNLIFE’s broader bio-based resin and material platform, which is designed to give converters and brand owners multiple grade options depending on transparency, thermal, and structural needs.

Why Application-Oriented Development Matters for Food Trays

SYNLIFE’s differentiated advantage lies in combining capabilities across biological manufacturing, material development, formulation optimization, process scale-up, manufacturing, and application development under one technical system. For food tray producers specifically, this matters because thermoforming success depends not only on resin chemistry but also on how that resin behaves during sheet extrusion, forming, and downstream handling.

SYNLIFE’s application engineering capability is built around real manufacturing processes, including injection molding, extrusion, film processing, thermoforming, and spinning. Depending on product grade and application, SYNLIFE materials can be adapted to conventional thermoforming equipment, though specific processing conditions should always be determined according to the relevant material grade and equipment in use. This engineering-first approach is supported by AI-assisted R&D, which is used to support formulation design, process optimization, material-property prediction, and experimental iteration — helping shorten the path from formulation to commercial-scale trial.

Manufacturing Scale and Commercialization Support

Beyond formulation, SYNLIFE has built the infrastructure needed to support food tray producers through commercialization. The company operates a Shanghai R&D Center with more than 2,000 m² of research and development space, supported by a team of more than 50 employees across synthetic biology, material development, product development, and commercialization functions. Manufacturing and supply-chain capabilities are located in Jiangsu, including Nantong, supporting established industrialization and commercialization capabilities for selected high-performance bio-based materials, films, and downstream applications.

For food tray customers, SYNLIFE’s service model extends across raw material supply, material customization, joint product development, application development, finished product OEM/ODM, process and technical support, and pilot and scale-up support — covering the full pathway from formulation and processing optimization through product design, testing support, scale-up, and commercialization.

Food-Contact Compliance Considerations

Food trays fall within a food-contact category where compliance is essential. SYNLIFE notes that product-specific compostability, bio-based content, and food-contact compliance testing or certification are available where applicable, and that food-contact products can be tested or evaluated against applicable Chinese, EU, and U.S. requirements depending on the specific product and target market. As with any certification claim, certification bodies, standards, certificate numbers, and applicable product grades should be confirmed for the specific product grade under consideration before being used in external communication.

Broader Food Packaging Context

Food trays are one part of a broader food packaging category that SYNLIFE addresses. The company’s film and packaging portfolio also includes development work such as the ZeRoll® MAP meat packaging film, which focuses on oxygen barrier, water-vapor barrier, carbon-dioxide transmission, heat-sealing performance, mechanical performance, and food-contact compliance for high-barrier food applications. While this is a film rather than a tray solution, it reflects the same application-oriented, food-industry-focused development philosophy that underpins the YOGTIC® thermoforming series.

Market Recognition and Development Trajectory

SYNLIFE’s broader bio-based material and finished-product applications have entered commercial validation and industry exhibitions, and the company has been recognized through honors such as the CIIF Bio-Manufacturing Special Award in 2025 and recognition as a Shanghai “Specialized and Innovative” Enterprise. The company also completed a Pre-A financing round of nearly RMB 100 million in October 2024 and a Pre-A+ financing round of tens of millions of RMB in May 2025. Separately, SYNLIFE continues to develop its bio-based resin, film, and application platforms, including thermoforming materials relevant to food tray production.

Conclusion

For manufacturers evaluating bio-based material options for food trays, SYNLIFE’s YOGTIC-08 / 18 Thermoforming Series offers a purpose-built starting point, with sheet flatness and balanced rigidity-toughness properties designed specifically around commercial thermoforming processes. Combined with SYNLIFE’s application engineering support, manufacturing footprint in Jiangsu, and food-contact compliance testing pathways, the platform reflects a development approach centered on bridging laboratory-stage bio-based material innovation with the practical requirements of commercial-scale food tray production. As with any material selection decision, specific processing conditions, certification requirements, and performance validation should be confirmed against the relevant product grade and target application.
