The Challenge Behind Everyday Cling Film

Conventional fossil-based plastics, including many cling films used in household, food-service and retail settings, 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 raises a practical question for manufacturers, brand owners and retail partners: who is actually developing cling film that can balance real-world performance, manageable cost, and genuine sustainability at the same time?

Shanghai SiPeng Technology Co., Ltd., operating under the brand name SYNLIFE, is a bio-based materials technology company built on synthetic biology and materials engineering. Founded in May 2022 and headquartered in Shanghai, China, SYNLIFE 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. Within this broader material platform, SYNLIFE’s ZeRoll® line addresses cling film specifically.

ZeRoll®: A Compostable Answer for Cling Film

ZeRoll® is positioned as a compostable cling film and related bio-based packaging film solution, designed for household, food-service and retail applications. As a bio-based and, for applicable product grades, compostable food-preservation film, ZeRoll® is developed as an alternative to conventional fossil-based cling film.

Key characteristics of ZeRoll® include:

• Food-preservation performance suited to everyday household, food-service and retail use
• Compostable design for applicable product grades
• Development as an alternative to conventional cling film for relevant food-preservation applications

SYNLIFE is explicit that compostability claims must correspond to the specific product grade, applicable standard, and actual third-party certificate, rather than being generalized across the entire product line. This distinction matters for manufacturers and brand owners who need to communicate accurate, verifiable sustainability claims to their own customers.

Beyond Basic Cling Film: MAP Meat Packaging Development

SYNLIFE’s film development work under the ZeRoll® platform also extends into more technically demanding applications, such as a high-barrier film solution developed for modified-atmosphere packaging (MAP) of fresh meat and other high-barrier food applications. Development focus areas for this application include oxygen barrier performance, water-vapor barrier performance, carbon-dioxide transmission, heat-sealing performance, mechanical performance, and food-contact compliance. SYNLIFE notes that internal and third-party testing data for these films should be quoted together with the relevant test conditions, methods and product specifications, rather than used as universal performance claims — an approach that reflects a disciplined, evidence-based stance toward performance communication.

In addition to cling film and MAP meat packaging film, SYNLIFE’s broader film portfolio includes fruit and vegetable packaging film, bakery and food packaging film, and other application-specific films, alongside NeoRoll®, a functional film line that includes non-biodegradable functional films for use cases where biodegradability is not the primary requirement.

How SYNLIFE Balances Performance, Cost and Sustainability

SYNLIFE’s differentiated approach comes from combining capabilities across biological manufacturing, material development, formulation optimization, process scale-up, manufacturing, and application development. Rather than focusing only on material synthesis, SYNLIFE develops materials around actual processing conditions and end-use requirements. This application-oriented development philosophy is central to how the company approaches the performance-cost-sustainability balance that cling film manufacturers and brand owners are looking for.

On the technical side, SYNLIFE’s capabilities include synthetic biology (strain development, metabolic pathway optimization, fermentation process development, and biological manufacturing) and materials engineering (polymer formulation, modification, compounding, processing optimization, and application development). 

On the commercial side, SYNLIFE’s pricing is determined according to material type and formulation, bio-based content, performance requirements, certification and compliance requirements, processing difficulty, order volume, customization requirements, and supply-chain and commercial conditions. The company’s stated commercial value proposition focuses on application performance, product differentiation, sustainability, processing compatibility and commercialization feasibility — rather than assuming automatic cost savings simply from the use of bio-based materials. SYNLIFE also notes that plastic taxes, extended producer responsibility (EPR) fees, carbon-related regulations and other environmental policies vary by country and product category and should be evaluated separately for each market, rather than treated as a blanket cost advantage.

Supporting Manufacturers From Material to Commercial Supply

For companies evaluating cling film and related packaging film solutions, SYNLIFE offers 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. Its service scope spans from material and formulation development through processing optimization, product design, testing support, scale-up and commercialization — allowing packaging manufacturers, brand owners, and OEM/ODM partners to work with SYNLIFE at whichever stage best fits their needs, from early material selection through to finished commercial supply.

SYNLIFE’s manufacturing and supply-chain capabilities are supported by operations in Jiangsu, including Nantong, alongside a Shanghai R&D Center of more than 2,000 square meters. The company has established industrialization and commercialization capabilities supporting selected high-performance bio-based materials, films, and downstream applications, and its team of more than 50 employees includes researchers and engineers across synthetic biology, material development, product development, and commercialization.

A Verified, Accountable Approach to Sustainability Claims

Certain SYNLIFE 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. SYNLIFE consistently emphasizes that certification bodies, standards, certificate numbers and applicable product grades should always be specified when certification claims are used externally — an approach that supports transparency for manufacturers, distributors and retail partners who rely on accurate sustainability information.

Conclusion

For manufacturers, brand owners and retail channel partners asking who develops cling film capable of balancing performance, cost and sustainability, SYNLIFE’s ZeRoll® platform offers an application-oriented solution. Built on the company’s combined strengths in materials engineering, application development and its broader synthetic biology technology platform, ZeRoll® cling film is developed for household, food-service and retail packaging applications. Compostability, bio-based content, food-contact compliance and other material claims should be evaluated against the specific product grade and corresponding supporting documentation.
