Industry Background and the Case for Bio-Based Stretch Film

Conventional fossil-based plastics used across packaging, including stretch film, continue to raise concerns tied 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. These tensions are particularly visible in flexible packaging categories such as stretch film, where mechanical performance, sealing behavior, and cost efficiency must all be reconciled with sustainability expectations.

Shanghai SiPeng Technology Co., Ltd., operating under the brand SYNLIFE, was established in May 2022 as a bio-based materials technology company built on synthetic biology and materials engineering. The company is advancing lower-carbon and carbon-negative biomanufacturing technologies as part of its long-term technology strategy. Its product portfolio spans biological manufacturing, bio-based resins, functional materials, and film-based packaging solutions. Within its ZeRoll® film platform, SYNLIFE develops solutions including compostable cling film, MAP packaging films, fruit and vegetable packaging films, and stretch-film solutions. The company’s founding and technical teams accumulated long-term research experience in synthetic biology, biological manufacturing, and bio-based materials, with key synthetic biology technologies derived from research associated with Shanghai Jiao Tong University. SYNLIFE has also been recognized as a Shanghai “Specialized and Innovative” Enterprise.

Authoritative Analysis: Material Design Principles Behind SYNLIFE’s Film Platform

Packaging film performance is not a single-dimension question. For high-barrier applications such as the ZeRoll® MAP meat packaging film, SYNLIFE’s development focus explicitly covers oxygen barrier, water-vapor barrier, carbon-dioxide transmission, heat-sealing performance, mechanical performance, and food-contact compliance. These performance categories are also relevant when developing stretch film applications, where puncture resistance, cling behavior, and mechanical strength are important considerations for practical use.

The principle logic behind SYNLIFE’s approach rests on combining capabilities across biological manufacturing—strain development, metabolic pathway optimization, and fermentation process development—with materials engineering, including polymer formulation, modification, compounding, and processing optimization, and application engineering built around real manufacturing processes such as film processing and extrusion. AI-assisted R&D further supports formulation design, process optimization, material-property prediction, and experimental iteration, allowing data from experimental, formulation, process, and application-testing results to be continuously incorporated into ongoing development.

On standards, SYNLIFE’s materials framework is explicit that compostability claims must correspond to the specific product grade, the applicable standard, and the actual third-party certificate, and that internal or third-party testing data should be quoted together with the relevant test conditions, methods, and product specifications rather than treated as universal performance claims. In terms of solution paths, SYNLIFE offers multiple service models relevant to film development, including material supply, material customization, joint product development, application development, and selected finished-product OEM/ODM cooperation, process and technical support, and pilot and scale-up support—covering the full path from formulation through commercialization.

Deep Insights: Trends Shaping Bio-Based Film and Packaging

Several trends emerge from SYNLIFE’s material development priorities. On the technology side, the emphasis on barrier performance, heat sealing, and mechanical properties, supported by AI-assisted formulation and process optimization, indicates that bio-based film development is converging toward matching, rather than compromising on, conventional packaging performance benchmarks.

On the market side, SYNLIFE’s business scope spans food packaging, apparel and textiles, writing instruments and consumer goods, cosmetics and personal care, agriculture and horticulture, 3D printing, and other plastic and polymer applications, serving material and plastic product manufacturers, packaging manufacturers, brand owners, OEM/ODM manufacturers, importers and distributors, and retail and commercial channel partners. This breadth suggests that demand for bio-based film solutions is not confined to a single vertical but is spreading across multiple downstream categories that share common packaging needs.

A key risk consideration flagged within SYNLIFE’s own materials is the need for precision in certification claims: certification bodies, standards, certificate numbers, and applicable product grades should always be specified when such claims are used externally, since compostability, bio-based content, and food-contact compliance testing apply where applicable to specific products rather than as blanket statements. Related to this, food-contact products can be tested or evaluated against applicable Chinese, EU, and U.S. requirements depending on the product and target market, pointing toward a broader standardization direction in which regional compliance frameworks must be addressed individually rather than assumed to be interchangeable.

Company Value: How SYNLIFE Strengthens the Bio-Based Film Supply Chain

SYNLIFE’s ability to support bio-based film commercialization is anchored in its material development capabilities, manufacturing resources, and application engineering infrastructure. The company operates manufacturing and supply-chain capabilities in Jiangsu, including Nantong, and has established commercial-scale capabilities for high-performance bio-based materials, films, and downstream applications. Its team of more than 50 employees includes researchers and engineers across synthetic biology, material development, product development, and commercialization, supported by a Shanghai R&D Center exceeding 2,000 square meters. SYNLIFE and its founding technical teams have accumulated multiple patents and proprietary technical know-how across synthetic biology and materials development.

Strategic partnerships further reinforce this capability base. SYNLIFE established a strategic partnership with Angel Yeast in November 2022 and formed a joint venture with Angel Yeast in December 2023 to advance the industrialization and commercialization of bio-manufactured products. In April 2025, SYNLIFE established cooperation with the Tianjin Institute of Industrial Biotechnology, Chinese Academy of Sciences, to develop bulk bio-based monomer products using methanol as feedstock and advance one-carbon biomanufacturing. These collaborations extend beyond film alone but reflect the underlying biological manufacturing platform on which film and other material lines are built.

 

Financing history also signals sustained investment in this direction: SYNLIFE completed a Pre-A financing round of nearly RMB 100 million in October 2024, followed by a Pre-A+ financing round of tens of millions of RMB in May 2025, alongside continued expansion of international customer development and commercial projects. Recognition of the company’s technical and industry contributions includes the CIIF Bio-Manufacturing Special Award in 2025, and selection as one of 16 winners of Tencent’s CarbonX Program 2.0 in 2026, following a global selection process involving approximately 660 applications from 54 countries and regions and 50 finalists.

Conclusion and Recommendations for Industry Decision-Makers

Bio-based stretch film, as part of SYNLIFE’s broader ZeRoll® film and packaging solutions, illustrates how cross-disciplinary capability—spanning biological manufacturing, materials engineering, and application engineering—can be applied to address long-standing packaging challenges. For converters, brand owners, and packaging manufacturers evaluating bio-based film options, several practical considerations follow directly from SYNLIFE’s own materials: first, compostability, bio-based content, and food-contact compliance claims should always be matched to the specific product grade and verified against the relevant certification body, standard, and certificate; second, pricing for bio-based materials should be understood as a function of material type and formulation, bio-based content, performance requirements, certification and compliance needs, processing difficulty, order volume, customization requirements, and supply-chain conditions, rather than assumed to deliver automatic tax savings; and third, because plastic taxes, extended producer responsibility fees, carbon-related regulations, and other environmental policies vary by country and product category, each target market should be evaluated separately. Decision-makers exploring commercialization pathways may also consider engaging through material customization, joint product development, or pilot and scale-up support models to align formulation and processing requirements with commercial-scale outcomes before full deployment.
