Understanding Material-to-Application Development in Stretch Film

When buyers ask who actually provides material-to-application development for stretch film, they are asking a deeper question than “who manufactures rolls of film.” They want to know which organization controls the process from raw polymer chemistry all the way through to a finished product that performs on a real packaging line. For the ZeRoll® Fully Biodegradable Stretch Film line, that organization is Shanghai Sipeng Technology Ltd., operating under the brand name SYNLIFE, headquartered at Building 4, No. 878, Jianchuan Road, Minhang District, Shanghai, China.

 

SYNLIFE is described as a technology company built on synthetic biology and materials engineering, developing high-performance bio-based materials, products, and cross-industry application solutions for global customers. Its stated capabilities span material development and modification, application engineering, product development, manufacturing, and supply-chain integration. In other words, the company does not simply buy resin and convert it into film; it participates in the material science itself and carries that work forward into finished, application-ready products such as ZeRoll®.

SYNLIFE’s Integrated Capability System

Within SYNLIFE’s broader film portfolio, ZeRoll® includes fully biodegradable stretch-film solutions developed for pallet wrapping, logistics, warehousing, manufacturing, food & beverage operations, export packaging, and automated packaging applications. This breadth of use cases is only possible because the company’s capability system connects several stages:

• Material development and modification — the foundational polymer science work.
• Application engineering — translating material properties into film behavior suited to specific wrapping scenarios.
• Product development — shaping the engineered material into a usable roll-stock product.
• Manufacturing — producing the film at the specifications required.
• Supply-chain integration — ensuring the finished product reaches customers in the formats they need.

This chain is the practical answer to “who provides material-to-application development”: it is the same entity, SYNLIFE, moving the project from laboratory-level material work to a deployable stretch-film product under the ZeRoll® brand.

From Polymer Modification to ZeRoll® Stretch Film

The proprietary R&D underpinning ZeRoll® includes polymer material modification technology, a multi-layer co-extruded structure, and a special tack-enhancing formula. These three elements illustrate how material-level work becomes application-level performance:

• Polymer material modification technology supports the development of ZeRoll®’s biodegradable stretch-film material system, directly addressing the pain point that conventional polyethylene stretch film leaves persistent plastic waste and heightens regulatory/legal exposure.
• The multi-layer co-extruded structure improves puncture resistance, which answers the practical problem that heavy loads and sharp corners can cause wrapping film to break and destabilize.
• The special tack-enhancing formula provides adjustable tackiness from 0.8 N to 6.5 N, giving converters and end users a way to control adhesion without leaving adhesive residue that could contaminate wrapped goods and equipment.

ZeRoll® is positioned as a fully biodegradable stretch-film solution, with the clarification that specific biodegradation or compostability claims must correspond to the applicable product, supporting documentation, standard, and specified end-of-life conditions. At the same thickness, ZeRoll® is described as providing higher tensile strength, better tear resistance, and stronger resilience than traditional plastic film.

Technical Performance Built Into Every Roll

The material-to-application work shows up most clearly in the measured performance of the film at a thickness of 0.022 mm:

• Elastic recovery: approximately 70%, compared with approximately 50% for conventional stretch films, helping goods stay tightly wrapped during transport.
• Adjustable tackiness: 0.8–6.5 N.
• Tensile Strength-MD: approximately 50–52 MPa; Tensile Strength-TD: approximately 35–40 MPa.
• Elongation at Break-MD: approximately 620–700%; Elongation at Break-TD: approximately 840–880%.
• Tear Strength-MD: approximately 110–120 kN/m; Tear Strength-TD: approximately 120–130 kN/m.
• Transmittance: approximately 85–90%, supporting clear barcode identification on automated lines.
• Haze: approximately 20–24%.
• Self-Adhesion: approximately 1.3–1.6 N/cm².
• MD tensile-strength increase: approximately 20% versus the peer-mainstream reference at 0.022 mm; MD tear-strength increase: approximately 30% versus the peer-mainstream reference at 0.022 mm.

These figures are drawn from internal test results and average values from publicly available industry samples, provided for performance comparison only, with specific parameters subject to the testing of contract samples. The resulting film addresses several application-level pain points directly: low-transparency film can block barcode scanning, automated packaging lines need stable unwinding, high-speed compatibility, and low operating noise, and excess film consumption raises material cost and waste. ZeRoll®’s uniform thickness, smooth edges, and seamless unwinding are described as supporting high-speed and fully automatic winding equipment with lower noise, while material efficiency allows the same wrapping performance with less film usage.

Industry Applications and Equipment Compatibility

SYNLIFE develops stretch-film solutions for manual, semi-automatic, and automatic pallet-wrapping applications. Film grade, thickness, roll format, recommended pre-stretch, and operating parameters are matched to the specific wrapping equipment and application. Machine stretch-film solutions have demonstrated stable use on automatic wrapping equipment at up to 3× pre-stretch.

This equipment-matching approach reflects the “application engineering” stage of the capability system and explains why ZeRoll® is adapted across multiple industries:

• Logistics and Warehousing — pallet packing and warehousing/sortation centers.
• Manufacturing — transportation of industrial products.
• Food & Beverage Industry — secondary and tertiary pallet-wrapping and transport-packaging applications; ZeRoll® stretch film is not positioned as a direct food-contact film.
• Agriculture — an alternative to traditional plastic wrap for agricultural applications.
• Export Packaging — protection for export goods.
• Automated Packaging Lines — compatibility with automated wrapping lines.

Certification and Documentation Supporting the Claims

Material-level industrial-composting documentation is available under DIN EN 13432:2000-12 for YOGTIC-05D resin, registered as DIN-Geprüft Registration No. 9K0326, valid until September 30, 2031, certifying “Compostable material for industrial composting.” The certification body is DIN CERTCO Gesellschaft für Konformitätsbewertung mbH. This is explicitly a material-level certificate and must not be presented as certification of the finished ZeRoll® stretch film unless the finished film is explicitly covered by the applicable certificate scope.

Separately, SGS Test Report No. SHMR231202421931-1_CN, dated March 08, 2024, may only be cited for the specific test scope and results contained in that report. Together, these two documents represent the third-party verification layer sitting underneath SYNLIFE’s internal material-to-application process.

Delivery Model and Equipment Fit

Stretch-film solutions are supplied as roll stock for different wrapping applications. Film grade, thickness, roll format, recommended pre-stretch, and operating parameters should be matched to the specific manual, semi-automatic, or automatic wrapping equipment in use. Physical stretch film rolls are available for manual, semi-automatic, and fully automatic stretch-wrapping applications, with film specifications matched to the intended equipment and operating conditions. Existing ZeRoll® solutions can be integrated into suitable packaging operations, while application testing or further customization may be required for specific customer equipment.

In summary, the material-to-application development behind ZeRoll® stretch film originates with Shanghai Sipeng Technology Ltd. under its SYNLIFE brand, through a capability system that connects polymer-level material modification to application engineering, product development, manufacturing, and supply-chain integration — delivering a fully biodegradable stretch film built to match the thickness, strength, and automation requirements of logistics, warehousing, manufacturing, food & beverage, agriculture, and export-packaging operations.
