Custom Cling Wrap Manufacturer: Proven Private Label Partner

Why Private Label Brands Are Rethinking Cling Wrap Sourcing

Household, food-service and retail brands that sell cling film under their own label face a recurring sourcing challenge: conventional fossil-based plastics create fossil-resource dependence, long-term environmental persistence and end-of-life waste management concerns, while many emerging bio-based and biodegradable material systems still struggle to balance performance, processability, cost and large-scale commercialization. For a private label buyer evaluating a custom cling wrap manufacturer, this trade-off is the central question — and it is the exact problem that Shanghai SiPeng Technology Co., Ltd., operating under the brand SYNLIFE, addresses through its bio-based materials and application development capabilities.

A Bio-Based Materials Company With Full-Chain Capability

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, SYNLIFE develops materials around actual processing conditions and end-use requirements — an application-oriented approach that matters directly to private label buyers who need film that performs reliably on real production lines, not just in a laboratory setting.

This full-chain capability spans biological manufacturing, material development, formulation optimization, process scale-up, manufacturing and application development. For a company evaluating custom cling wrap production, this means a single technology partner can move a project from raw material selection through formulation, processing optimization, product validation, testing, scale-up and commercial supply, rather than requiring buyers to coordinate separately with a materials supplier, a converter and a testing lab.

ZeRoll®: Purpose-Built for Private Label Cling Film

Within SYNLIFE’s film and packaging solutions portfolio, ZeRoll® is a film brand that includes compostable cling-film products developed for food-preservation applications in household, food-service and retail scenarios. Its key features include:

• Food-preservation performance suited to household and commercial use
• Bio-based content where applicable to the specific product grade
• Compostable design for applicable product grades
• A design intent to serve as an alternative to conventional fossil-based cling film

For private label programs, these characteristics matter because they align with growing retail and food-service demand for sustainability-oriented packaging without requiring buyers to compromise on the basic functional expectation of a cling film: reliable food preservation. It should be noted that compostability claims must correspond to the specific product grade, the applicable standard and the actual third-party certificate — a discipline that protects brand owners from making unsupported sustainability statements downstream.

Beyond the core cling film line, SYNLIFE is developing a ZeRoll® MAP meat packaging film solution for modified-atmosphere packaging of fresh and chilled meat applications. Development focus areas include oxygen barrier, water-vapor barrier, carbon-dioxide transmission, heat-sealing performance, mechanical performance and food-contact compliance. This reflects SYNLIFE’s ongoing development of film solutions addressing different packaging performance requirements relevant to food-oriented private label buyers.

Service Models Built for Private Label Partners

A private label buyer typically needs more than a product catalog — they need a manufacturing partner capable of adapting to brand-specific requirements. SYNLIFE’s service capabilities are structured to support exactly this kind of engagement, including:

• Raw material supply
• Material customization
• Joint product development
• Application development
• Finished product OEM/ODM
• Process and technical support
• Pilot and scale-up support

This service scope covers everything from material and formulation development through processing optimization, product design, testing support, scale-up and commercialization. For a brand seeking custom cling wrap under its own label, this range of services means the manufacturing relationship can start with raw resin supply for an existing converting line, or extend all the way to finished-product OEM/ODM, depending on the buyer’s internal capabilities and go-to-market needs.

Manufacturing Scale and Technical Foundation

SYNLIFE’s commercial and technical foundation supports this kind of partnership. The company maintains a Shanghai R&D Center with more than 2,000 square meters of research and development space, supported by a team of more than 50 employees, including researchers and engineers in synthetic biology, material development, product development and commercialization. Manufacturing and supply-chain capabilities are established in Jiangsu, including Nantong, supporting the industrialization and commercialization of selected high-performance bio-based materials, films and downstream applications.

Financially, 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 — funding history that reflects continued investment in the company’s biological manufacturing and materials platform. The company has also been recognized as a Shanghai “Specialized and Innovative” Enterprise and was selected as one of 16 winners from approximately 660 global applications across 54 countries and regions in Tencent’s CarbonX Program 2.0 for its carbon-negative biomanufacturing technology direction.

Pricing and Compliance: Set Expectations, Not Assumptions

For private label buyers evaluating cost, SYNLIFE determines pricing 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. Importantly, the company’s commercial value proposition centers on application performance, product differentiation, sustainability, processing compatibility and commercialization feasibility — rather than assuming automatic tax savings from the use of bio-based materials. 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 target market.

Similarly, on compliance, 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 specific product and target market. Brands considering ZeRoll® for private label programs should confirm certification bodies, standards, certificate numbers and applicable product grades for the specific film grade under consideration, rather than relying on general category claims.

A Development Path Grounded in Real Commercial Traction

SYNLIFE’s broader development history — from its November 2022 strategic partnership with Angel Yeast, formalized into a joint venture in December 2023 to advance industrialization and commercialization of bio-manufactured products, to its April 2025 cooperation with the Tianjin Institute of Industrial Biotechnology, Chinese Academy of Sciences, on methanol-based bio-based monomer development — reflects a company oriented toward moving bio-based materials from laboratory innovation into commercial-scale applications across multiple industries, including food packaging, apparel and textiles, writing instruments, cosmetics and personal care, and agriculture and horticulture.

For a private label brand searching for a custom cling wrap manufacturer, this combination of application-oriented material development, a defined service model spanning raw material supply through finished-product OEM/ODM, established Jiangsu-based manufacturing capability, and disciplined, grade-specific compliance practices positions SYNLIFE as a technically grounded partner for building a compostable or bio-based cling film program under a brand’s own label.
