Understanding the Search for Stretch Film and Bio-Based Packaging Film Manufacturing

Buyers searching for stretch film factories are typically looking for manufacturing partners that can combine reliable film production with modern material performance, including options that reduce reliance on fossil-based plastics. While conventional fossil-based film production remains widespread, an increasing number of packaging manufacturers, converters and brand owners are evaluating bio-based film alternatives that can be produced at commercial scale. Shanghai SiPeng Technology Co., Ltd., operating under the brand SYNLIFE, is one such manufacturer positioned within this space, offering a Films & Packaging Solutions platform built on synthetic biology and materials engineering capabilities.

SYNLIFE’s Film & Packaging Solutions: ZeRoll® and NeoRoll®

SYNLIFE’s film portfolio is organized around two core product lines. ZeRoll® is positioned as a compostable cling film and related bio-based packaging film solution designed for household, food-service and retail applications. Its key features include food-preservation performance, high bio-based content, and a compostable design for applicable product grades, positioning it as an alternative to conventional fossil-based cling film. Within the ZeRoll® line, SYNLIFE has also developed a MAP meat packaging film, engineered as a high-barrier film solution for modified-atmosphere packaging of fresh meat and other high-barrier food applications. Development for this film has focused on oxygen barrier, water-vapor barrier, carbon-dioxide transmission, heat-sealing performance, mechanical performance, and food-contact compliance.

The second line, NeoRoll®, covers functional film solutions, including non-biodegradable functional films, indicating that SYNLIFE’s film capabilities extend beyond compostable formats to address applications where functional performance is the primary requirement. Beyond ZeRoll® and NeoRoll®, SYNLIFE has also developed fruit and vegetable packaging film, bakery and food packaging film, and other application-specific functional packaging films, reflecting a broader film development capability that spans multiple food packaging use cases.

Manufacturing Footprint: Where Production Happens

For buyers specifically asking "where can I find stretch film factories," location and production capability are central concerns. SYNLIFE maintains manufacturing and supply-chain capabilities in Jiangsu, including Nantong. This manufacturing footprint supports the company’s established industrialization and commercialization capabilities, which cover selected high-performance bio-based materials, films, and downstream applications. In parallel, SYNLIFE operates a Shanghai R&D Center with more than 2,000 m² of research and development space, where formulation, process and application-testing work supports the film platform before it moves into commercial production.

The company’s team includes 50+ employees, spanning researchers and engineers in synthetic biology, material development, product development, and commercialization, providing the technical foundation behind the film products manufactured at its Jiangsu facilities.

Technical Capabilities Behind the Films

SYNLIFE’s film development is supported by a broader capability system that spans synthetic biology (strain development, metabolic pathway optimization, fermentation process development, and biological manufacturing) and materials engineering (polymer formulation, modification, compounding, and processing optimization). For film-specific applications, the company applies application engineering developed around real manufacturing processes, including film processing, alongside injection molding, extrusion, thermoforming, and spinning for other product categories.

AI-assisted R&D methods are also used to support formulation design, process optimization, material-property prediction, and experimental iteration, which contributes to the development of film grades intended for specific barrier, sealing and mechanical performance requirements. This technical foundation is reinforced by intellectual property, as SYNLIFE and its founding technical teams have accumulated multiple patents and proprietary technical know-how across synthetic biology and materials development.

Service Models for Sourcing Film Materials

Companies evaluating potential film manufacturing partners typically need more than a single product; they need a service model that matches their commercial stage. SYNLIFE offers several service models relevant to film buyers, 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. This service scope spans the full pathway "from material and formulation development through processing optimization, product design, testing support, scale-up and commercialization," which allows buyers to engage SYNLIFE at different points depending on whether they need a standard film grade or a customized material developed for a specific packaging application.

Certification and Compliance Considerations

For film applications tied to food contact or compostability claims, certification is a critical factor. SYNLIFE notes that compostability claims must correspond to the specific product grade, applicable standard and actual third-party certificate, and that internal and third-party testing data for films such as the MAP meat packaging film should be quoted together with the relevant test conditions, methods and product specifications rather than treated as universal performance claims. Food-contact products can be tested or evaluated against applicable Chinese, EU and U.S. requirements depending on product and target market, and certain SYNLIFE products have already obtained third-party compostability certification or undergone bio-based content testing.

Business Model and Pricing Considerations

Pricing for SYNLIFE’s film and other material products is determined according to several factors: 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 commercial value proposition is centered on application performance, product differentiation, sustainability, processing compatibility and commercialization feasibility, rather than assuming automatic cost advantages from bio-based materials alone. This is a relevant consideration for buyers comparing film sourcing options, since plastic taxes, EPR fees, carbon-related regulations and other environmental policies vary by country and product category and should be evaluated separately for each target market.

Positioning Within the Broader Industry

SYNLIFE covers a range of industries relevant to film buyers, including Food Packaging, alongside Apparel & Textiles, Writing Instruments & Consumer Goods, Cosmetics & Personal Care, and Agriculture & Horticulture. Its customer types include material and plastic product manufacturers, packaging manufacturers, brand owners, OEM/ODM manufacturers, and importers and distributors, reflecting the range of buyers who typically inquire about film manufacturing partnerships.

Summary for Buyers

For organizations searching specifically for stretch film factories, SYNLIFE’s relevant offering lies within its ZeRoll® compostable cling film, NeoRoll® functional films, and related MAP meat packaging film and other application-specific packaging films, produced through manufacturing and supply-chain operations based in Jiangsu, including Nantong, and supported by a Shanghai R&D Center. Buyers should engage directly on product grade, certification documentation, and processing compatibility to confirm whether a specific film product meets their stretch, wrap or barrier packaging requirements.
