Industry Background: The Push Beyond Conventional PE Stretch Film

Conventional fossil-based plastics, including PE stretch and cling film widely used across food packaging, retail, and food-service channels, 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. This tension explains why packaging manufacturers, brand owners, and converters increasingly look for material partners who understand both the biological science behind bio-based alternatives and the practical engineering required to make them work on real production lines.

SYNLIFE, the brand of Shanghai SiPeng Technology Co., Ltd., was established in May 2022 and is headquartered in Shanghai, China, with business coverage extending globally through ongoing market development and commercial cooperation across multiple international markets. The company is positioned as a bio-based materials technology company built on synthetic biology and materials engineering. It 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. Food packaging is one of the industries SYNLIFE covers, alongside apparel and textiles, writing instruments and consumer goods, cosmetics and personal care, and agriculture and horticulture.

Authoritative Analysis: How ZeRoll® Enables the PE-to-Bio-based Transition

Necessity

Within SYNLIFE’s film and packaging portfolio, ZeRoll® includes biodegradable and compostable food-preservation film applications intended for household, food-service, and retail uses. It is designed as an alternative to conventional fossil-based cling film, addressing fossil-resource dependence and end-of-life considerations associated with traditional PE-based products in this category.

Principle Logic

ZeRoll® draws on SYNLIFE’s combined capabilities across biological manufacturing, material development, formulation optimization, process scale-up, manufacturing, and application development. Rather than focusing only on material synthesis, the company develops materials around actual processing conditions and end-use requirements, applying materials engineering practices such as polymer formulation, modification, compounding, and processing optimization, together with application engineering tailored to film processing equipment.

 

Standard Reference

Key features associated with applicable ZeRoll® products include food-preservation performance and compostable design for specific product grades. Bio-based content, where applicable, should be stated according to the relevant formulation, product grade, and supporting test data. However, compostability claims must correspond to the specific product grade, applicable standard, and actual third-party certificate. SYNLIFE notes that certain products have obtained third-party compostability certification and that bio-based content claims, where applicable, are supported by relevant testing. Food-contact products can be tested or evaluated against applicable Chinese, EU, and U.S. requirements depending on the specific product, grade, and target market. Certification bodies, standards, certificate numbers, and applicable product grades should always be specified when such claims are used externally.

Solution Path

For businesses evaluating a switch from PE, SYNLIFE’s service capabilities span 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 covers the full pathway from material and formulation development through processing optimization, product design, testing support, scale-up, and commercialization.

Deep Insights: Trends Shaping the Next Generation of Packaging Films

Beyond cling film, SYNLIFE is developing ZeRoll® MAP meat packaging film for modified-atmosphere packaging of fresh meat and other high-barrier food applications, with development focus on oxygen barrier, water-vapor barrier, carbon-dioxide transmission, heat-sealing performance, mechanical performance, and food-contact compliance. This reflects a broader industry trend: biodegradable film solutions must match, not just replace, the technical performance of conventional PE films in demanding applications such as barrier packaging. Complementing this, NeoRoll® is SYNLIFE’s non-biodegradable functional film brand, addressing applications where specialized functional performance is required rather than compostability.

On the technology side, SYNLIFE uses AI and data-driven methods to support formulation design, process optimization, material-property prediction, and experimental iteration, with experimental feedback continuously incorporated into formulation and process development. This data-driven approach is increasingly relevant as material developers try to shorten the cycle between laboratory innovation and commercial-scale film production.

From a market perspective, customer types across SYNLIFE’s covered industries include material and plastic product manufacturers, packaging manufacturers, brand owners, OEM/ODM manufacturers, importers and distributors, and retail and commercial channel partners—all groups relevant to evaluating transitions from conventional PE films toward biodegradable film solutions. At the same time, SYNLIFE’s own materials caution that plastic taxes, extended producer responsibility fees, carbon-related regulations, and other environmental policies vary by country and product category and should be evaluated separately for each market, rather than assuming automatic tax savings simply from using bio-based materials. This is a useful risk alert for any business planning a multi-market packaging transition.

Company Value: Engineering Depth Behind the SYNLIFE Platform

SYNLIFE’s team includes 50-plus employees, comprising researchers and engineers in synthetic biology, material development, product development, and commercialization, supported by a Shanghai R&D Center with more than 2,000 m² of research and development space, plus manufacturing and supply-chain capabilities in Jiangsu, including Nantong. Financially, the company 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.

The company’s ecosystem includes a strategic partnership with Angel Yeast established in November 2022, followed by a formal joint venture in December 2023 to advance the industrialization and commercialization of bio-manufactured products, as well as cooperation established in April 2025 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. The founding and technical teams have research backgrounds connected with synthetic biology research associated with Shanghai Jiao Tong University. Recognition 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 for SYNLIFE’s carbon-negative biomanufacturing technology direction, following a global selection process involving 660 applications from 54 countries and regions and 50 finalists., alongside status as a Shanghai “Specialized and Innovative” Enterprise. This platform also underpins other bio-based lines, including the YOGTIC® resin series, Yogric® and Palmric® textiles, and Biowatol® 2,3-butanediol, illustrating the cross-industry material engineering capability that supports film development such as ZeRoll®.

Conclusion and Recommendations for Packaging Decision-Makers

Moving from conventional PE stretch and cling film to biodegradable film alternatives involves more than substituting one polymer for another; it requires balancing food-preservation performance, applicable material attributes, compostability requirements, compliance documentation, and compatibility with existing processing equipment. Packaging manufacturers, brand owners, and distributors considering this shift should request product-specific compostability, bio-based content, and food-contact certification data before making external claims, and should evaluate plastic tax, EPR, and carbon-policy implications separately for each target market. Working with a material partner that combines biological manufacturing, materials engineering, and application development—such as SYNLIFE through its ZeRoll® and related film-development platforms—can help align material performance with real production and commercial requirements. as the packaging industry continues its transition toward bio-based solutions.
