Packaging Stretch Film Guide: SYNLIFE’s Industrial Pallet Stretch Film Solutions

Understanding the Demand for Sustainable Packaging Stretch Film in China

Buyers searching for a packaging stretch film supplier in China are increasingly asking a more specific question: can a film deliver the elongation, holding force, load retention, puncture resistance, cling, and wrapping-equipment compatibility required for pallet stabilization while also meeting their material and sustainability requirements? Conventional fossil-based plastics create well-documented 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 is the exact gap that SYNLIFE, the brand of Shanghai SiPeng Technology Co., Ltd., was built to address.

SYNLIFE: A Bio-Based Materials Technology Company

Founded in May 2022 and headquartered in Shanghai, China, SYNLIFE is positioned as a bio-based materials technology company built on synthetic biology and materials engineering. 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. SYNLIFE has been recognized as a Shanghai “Specialized and Innovative” Enterprise, and its business coverage extends globally, with ongoing market development and commercial cooperation across multiple international markets.

Core Technology Behind SYNLIFE’s Film Solutions

Synthetic Biology and Materials Engineering

SYNLIFE’s differentiated advantage 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. In practice, this means film products are engineered with commercial manufacturing and processing compatibility in mind, so that, depending on product grade and application, materials can be adapted to conventional film-processing equipment.

AI-Assisted R&D

To support this development pipeline, SYNLIFE applies AI and data-driven methods to formulation design, process optimization, material-property prediction, and experimental iteration. Experimental data, formulation data, process data, and application-testing results are continuously incorporated into formulation and process development, allowing the company to accelerate screening and optimization for new film grades.

Product Spotlight: ZeRoll® and NeoRoll® Film Platforms

Industrial Pallet Stretch Film

SYNLIFE develops industrial stretch film for both hand and machine pallet-wrapping applications. Development focuses on maximum elongation and recommended pre-stretch, holding force and load retention, tensile and tear performance, puncture resistance, cling, COF, transparency, haze, and wrapping-equipment compatibility. SYNLIFE’s machine stretch film has demonstrated stable use on automatic wrapping equipment at up to 3× pre-stretch. These pallet stretch-film applications are non-food-contact uses, and sustainability claims should correspond to the specific product grade and supporting documentation.

Other Film and Packaging Applications

Separate from industrial pallet stretch film, SYNLIFE’s broader film portfolio includes ZeRoll® compostable cling-film products, MAP meat packaging film development, fruit and vegetable packaging film, bakery and food packaging film, and NeoRoll® non-biodegradable functional films. These product lines address different application requirements and should not be assumed to share the same barrier, food-contact, biodegradability, compostability, or bio-based-content attributes.

Manufacturing Scale and Commercialization Capability

SYNLIFE’s film and materials work is supported by a team of 50+ employees, including researchers and engineers in synthetic biology, material development, product development, and commercialization. R&D is centered at a Shanghai R&D Center with more than 2,000 m² of research and development space, while manufacturing and supply-chain capabilities are located in Jiangsu, including Nantong. Together, these resources give SYNLIFE established industrialization and commercialization capabilities supporting selected materials, film products, and downstream applications, including development and scale-up support for industrial packaging films.

Market Recognition and Compliance

SYNLIFE’s development has been supported by two funding rounds: a Pre-A financing round of nearly RMB 100 million completed in October 2024, and a Pre-A+ financing round of tens of millions of RMB completed in May 2025. On the recognition side, SYNLIFE was selected as one of the 16 winners of Tencent’s CarbonX Program 2.0 in 2026, following a global selection process that involved 660 applications from 54 countries and regions and 50 finalists. Compliance and certification requirements depend on the specific film application. SYNLIFE’s industrial pallet stretch film is a non-food-contact product, so food-contact testing or compliance documentation from cling film, MAP film, or other food-packaging products should not be transferred to pallet stretch film. Any biodegradability, compostability, or bio-based-content claim should likewise correspond to the exact stretch-film product grade and its supporting test or certification documentation.

Business Model: Flexible Collaboration for Brand Owners and Converters

For companies evaluating a packaging stretch film or bio-based film partner, SYNLIFE offers several service models: 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 everything from material and formulation development through processing optimization, product design, testing support, scale-up, and commercialization. Customer types served include material and plastic product manufacturers, packaging manufacturers, brand owners, OEM/ODM manufacturers, importers and distributors, and retail and commercial channel partners.

Pricing for SYNLIFE’s film products 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 conditions. Notably, SYNLIFE’s commercial value proposition focuses on application performance, product differentiation, sustainability, processing compatibility, and commercialization feasibility, rather than assuming automatic tax savings from the use of bio-based materials — since plastic taxes, EPR fees, carbon-related regulations, and other environmental policies vary by country and product category and must be evaluated separately for each market.

For buyers evaluating industrial stretch film in China, SYNLIFE combines materials engineering, formulation and film-processing capabilities, Shanghai-based R&D, and manufacturing and supply-chain capabilities in Jiangsu. Pallet stretch-film selection should ultimately be based on product-specific data for elongation and recommended pre-stretch, holding force and load retention, tensile and tear performance, puncture resistance, cling, COF, transparency, haze, and wrapping-equipment compatibility, with sustainability claims evaluated separately for the specific product grade.
