Shanghai Sipeng Technology Ltd. and the SYNLIFE Brand

Shanghai Sipeng Technology Ltd., operating under the brand name SYNLIFE and headquartered in Shanghai, China, is a technology company built on synthetic biology and materials engineering. Within its broader materials and application portfolio, the company develops ZeRoll® Fully Biodegradable Stretch Film for logistics and warehousing, manufacturing, food and beverage logistics, export packaging, and automated packaging applications, using materials engineering, polymer modification, and film-processing technologies.

ZeRoll® Fully Biodegradable Stretch Film: Product Positioning

Within the company's stretch-film offering, ZeRoll® Fully Biodegradable Stretch Film is positioned as an alternative to conventional PE stretch film, with strong mechanical performance at comparable thickness. Its biodegradation and compostability claims should be stated according to the applicable product evidence and specified disposal conditions. This positioning directly addresses several recurring operational pain points reported across target industries:

Pain Points the Product Is Designed to Address

· Conventional polyethylene stretch film is non-biodegradable and can create persistent plastic-waste management challenges, while the regulatory implications vary by market and application.

· Heavy loads and sharp corners can cause wrapping film to break and destabilize pallets.

· Automated packaging lines require stable unwinding, high-speed compatibility, and low operating noise.

· Low-transparency film can block barcode scanning during sortation and logistics processing.

· Adhesive residue can contaminate wrapped goods and equipment.

· Excess film consumption raises material cost and generates additional waste.

Differentiated Value and Technical Performance

Biodegradation and Environmental Compliance

ZeRoll® follows a biodegradable material route as an alternative to conventional non-biodegradable PE stretch film. Any biodegradation or industrial-compostability claim for the finished film should be stated according to the applicable product-level evidence and specified disposal conditions. The DIN EN 13432 documentation cited in this article applies to YOGTIC-05D resin and should not be treated as finished-product certification for ZeRoll® stretch film unless the final film is explicitly covered by the certificate.

Mechanical Strength and Load Stability

At a comparison thickness of 0.022 mm, the film reaches a Tensile Strength-MD of approximately 50–52 MPa and a Tensile Strength-TD of approximately 35–40 MPa. For context drawn from the same testing basis, peer mainstream products register approximately 40–45 MPa (MD) and 20–25 MPa (TD), while traditional PE registers 35–40 MPa (MD) and 20–25 MPa (TD). Elongation at Break reaches approximately 620–700% (MD) and approximately 840–880% (TD), compared with peer mainstream figures of roughly 600–650% (MD) and 800–850% (TD), and traditional PE figures of roughly 450–550% (MD) and 600–700% (TD). Together, these metrics support heavy-load stability during transport.

Tear Resistance and Puncture Protection

A multi-layer co-extruded structure underpins the film's puncture resistance. Tear Strength-MD reaches approximately 110–120 kN/m, versus roughly 85–95 kN/m for peer mainstream film and 60–80 kN/m for traditional PE. Tear Strength-TD reaches approximately 120–130 kN/m, close to the peer mainstream range of 125–135 kN/m and well above traditional PE's 80–100 kN/m. Overall, longitudinal strength is increased by about 20% and tear resistance is increased by about 30%, which reduces breakage at sharp corners.

Elastic Recovery and Load Containment

ZeRoll® delivers elastic recovery of approximately 70%, compared with approximately 50% for conventional stretch films according to the same test basis. This higher recovery helps keep goods tightly wrapped throughout transportation.

Adhesion Control

The film's special tack-enhancing formula allows tackiness to be adjusted from 0.8 N to 6.5 N, with self-adhesion measured at approximately 1.3–1.6 N/cm² (peer mainstream approximately 1.4–7 N/cm²; traditional PE approximately 1.0 N/cm²). This adjustability supports broader application options while still allowing clean peel without adhesive residue on wrapped goods.

Optical Clarity for Barcode Scanning

Transmittance of approximately 85–90% (peer mainstream approximately 85–95%; traditional PE 80–85%) and haze of approximately 20–24% (peer mainstream approximately 10–15%; traditional PE 20–30%) support clear barcode identification during handling and sortation.

Material Efficiency and Machine Stability

The film is designed to achieve the same wrapping performance with less material usage, reducing consumption and waste. Uniform thickness, smooth edges, and seamless unwinding allow it to run on high-speed winding equipment, fully automatic winding machines, and automated packaging lines with lower operating noise.

Core Technology Behind ZeRoll®

The product's performance is supported by polymer material modification technology, a multi-layer co-extruded structure that improves puncture and tear resistance, and a special tack-enhancing formula that provides an adjustable 0.8–6.5 N tackiness range. Its biodegradation behavior depends on the specific biodegradable material system, formulation, disposal conditions, and supporting product evidence. All performance figures above are based on internal test results and average values from publicly available industry samples, provided for comparison purposes; specific parameters remain subject to contract sample testing.

Third-Party Certification and Market Validation

Supporting third-party documentation should be interpreted according to its exact scope. DIN-Geprüft registration No. 9K0326, valid until September 30, 2031, covers YOGTIC-05D resin as a compostable material for industrial composting under DIN EN 13432:2000-12 and was issued by DIN CERTCO Gesellschaft für Konformitätsbewertung mbH. This raw-material certification should not be treated as certification of the finished ZeRoll® stretch film unless the final product is explicitly covered by the certificate. SGS report No. SHMR231202421931-1_CN, dated March 08, 2024, should likewise be cited only for the specific sample and test scope covered by that report.

Industry Applications and Delivery Model

ZeRoll® is positioned for use across logistics and warehousing (pallet packing, warehousing and sortation centers), manufacturing (transportation of industrial products), food processing (food and beverage industry wrapping), agriculture (as an alternative to traditional plastic wrap), and export packaging (protection for export goods), while remaining compatible with automated wrapping lines. The product is delivered as physical stretch film in roll stock form, suitable for manual, semi-automatic, and fully automatic stretch-wrapping equipment.

Summary

ZeRoll® Fully Biodegradable Stretch Film, developed by Shanghai Sipeng Technology Ltd. under the SYNLIFE brand, is designed to maintain reliable load containment and material efficiency while offering a biodegradable alternative to conventional PE stretch film. For operations evaluating such a transition, documented mechanical performance and compatibility with manual and automated wrapping equipment can be assessed directly, while biodegradation, compostability, regulatory implications, and disposal requirements should be verified separately against product-specific evidence and the requirements of the target market.
