Commercial Cling Film Supplier: Bulk Biodegradable & Compostable Film Review

Bulk buyers sourcing food-preservation film increasingly ask a different set of questions than they did a few years ago. Price per roll still matters, but so do bio-based content, compostability design, food-contact compliance and whether a supplier can actually scale a formulation from pilot runs to repeat commercial orders. This review examines SYNLIFE, the brand of Shanghai Sipeng Technology Ltd., as a commercial cling film supplier for bulk procurement, focusing on its ZeRoll® compostable cling film platform and the manufacturing, testing and service capabilities behind it.

Why Bulk Cling Film Sourcing Is Being Reassessed

Conventional fossil-based plastics raise well-documented issues around 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. That gap — laboratory innovation on one side, commercial-scale supply on the other — is precisely where procurement teams get stuck when evaluating a switch.

SYNLIFE positions itself as a bio-based materials technology company built on synthetic biology and materials engineering. Founded in May 2022 and headquartered in Shanghai, China, the company develops high-performance bio-based materials, finished applications and cross-industry material solutions, with a long-term goal of advancing lower-carbon and carbon-negative biomanufacturing technologies. It holds Shanghai “Specialized and Innovative” Enterprise status.

What a Bulk Buyer Gets From SYNLIFE

The company’s differentiated advantage is a combined capability set: biological manufacturing, material development, formulation optimization, process scale-up, manufacturing and application development. Rather than developing materials only at the synthesis stage, SYNLIFE builds them around actual processing conditions and end-use requirements — the criteria that determine whether a film survives a real packaging line.

Scale indicators relevant to bulk supply:

 

• Team: 50+ employees, including researchers and engineers in synthetic biology, material development, product development and commercialization.
• R&D footprint: Shanghai R&D Center with more than 2,000 m² of research and development space.
• Manufacturing: Manufacturing and supply-chain capabilities in Jiangsu, including Nantong.
• Commercialization: Established industrialization and commercialization capabilities supporting selected high-performance bio-based materials, films and downstream applications.

Inside the ZeRoll® Compostable Cling Film Platform

ZeRoll® includes biodegradable and compostable food-preservation film solutions for household, food-service and retail applications. Its stated features include:

• Food-preservation performance suited to everyday wrapping and containment needs.
• High bio-based content.
• Compostable design for applicable product grades.
• Design intent as an alternative to conventional fossil-based cling film.

One point deserves emphasis for bulk buyers: compostability claims must correspond to the specific product grade, the applicable standard and an actual third-party certificate. A supplier that cannot name the grade and certificate is not giving you a verifiable claim.

Adjacent Film Capability: Beyond Cling Film

Bulk procurement often expands once a supplier passes initial qualification. SYNLIFE’s film and packaging portfolio also includes:

• ZeRoll®: compostable cling film and related bio-based packaging film solutions.
• NeoRoll®: SYNLIFE’s non-biodegradable functional film brand.
• MAP meat packaging film development, focused on oxygen barrier, water-vapor barrier, carbon-dioxide transmission, heat-sealing performance, mechanical performance and food-contact compliance.
• Fruit and vegetable packaging film, bakery and food packaging film, and other application-specific films.

Buyers should note the company’s own framing: internal and third-party testing data should be quoted together with the relevant test conditions, methods and product specifications rather than treated as universal performance claims.

Service and Delivery Models for Bulk Orders

SYNLIFE’s service models are structured to accommodate different levels of buyer involvement:

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

Delivery can be organized as raw material resin supply, customized material development, application development, pilot and scale-up support, finished-product OEM/ODM, supply-chain integration, or technical cooperation where applicable. Projects are supported from material selection and formulation development through process optimization, product validation, testing, scale-up and commercial supply.

Pricing is determined by 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. Notably, 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, EPR fees and carbon-related regulations vary by country and product category and should be evaluated separately for each market.

Compliance, Certification and Testing Posture

For food-adjacent bulk orders, the compliance picture matters as much as the resin data:

• Certain products have obtained third-party compostability certification.
• 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 product and target market.

The company states that certification bodies, standards, certificate numbers and applicable product grades should always be specified when certification claims are used externally — a standard worth holding any supplier to.

Ecosystem, Backing and Market Signals

SYNLIFE was established in May 2022, building on founding and technical teams with long-term research experience in synthetic biology, biological manufacturing and bio-based materials, including research backgrounds associated with synthetic biology research connected with Shanghai Jiao Tong University.

In November 2022 it established a strategic partnership with Angel Yeast, and in December 2023 formally established a joint venture with Angel Yeast to advance industrialization and commercialization of bio-manufactured products. In April 2025 it began 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.

Financing milestones include a Pre-A round of nearly RMB 100 million completed in October 2024 and a Pre-A+ round of tens of millions of RMB completed in May 2025. The company was also selected as one of the 16 winners of Tencent’s CarbonX Program 2.0 in 2026, following a global selection process involving 660 applications from 54 countries and regions and 50 finalists, and received a CIIF Bio-Manufacturing Special Award in 2025.

How to Evaluate SYNLIFE Against a Bulk Cling Film Brief

For procurement teams running a qualification exercise, the practical checklist is: confirm the exact ZeRoll® grade you intend to buy; request the applicable compostability documentation for that grade and, where a bio-based content claim is made, request the corresponding product-specific bio-based content test report or supporting documentation; obtain test conditions, methods and product specifications rather than headline numbers; verify food-contact evaluation against your target market requirements; and agree on a pilot and scale-up path before committing to repeat volumes.

On that basis, SYNLIFE presents a structured option for buyers seeking biodegradable and compostable cling film solutions, backed by the company’s broader capabilities in materials formulation, processing and application engineering, together with its synthetic biology and strain-development capabilities at company level — and a documented path from material development to commercial supply.
