Why Stretch Film Selection Shapes Logistics Packaging Outcomes
Pallet wrapping decisions rarely rest on a single factor. Operations teams weigh load containment against film consumption, machine uptime against noise, and packaging compliance against disposal cost. Conventional polyethylene stretch film leaves persistent plastic waste and heightens regulatory and legal exposure — a consideration that grows more pressing as export and food & beverage customers tighten their own environmental requirements. At the same time, heavy loads and sharp corners can cause wrapping film to break and destabilize a loaded pallet, while automated packaging lines need stable unwinding, high-speed compatibility, and low operating noise.
Shanghai Sipeng Technology Ltd., trading as SYNLIFE, develops stretch-film solutions against exactly those constraints. The company is built on synthetic biology and materials engineering, developing high-performance bio-based materials, products, and cross-industry application solutions for global customers, with capabilities spanning material development and modification, application engineering, product development, manufacturing, and supply-chain integration. Within its broader film portfolio, ZeRoll® includes biodegradable stretch-film solutions developed for pallet wrapping, logistics, warehousing, manufacturing, food & beverage operations, export packaging, and automated packaging applications.
What the ZeRoll® Fully Biodegradable Stretch Film Is Designed to Do
ZeRoll® Biodegradable Stretch Film is positioned as a bio-based material solution stretch film designed to provide competitive mechanical performance at comparable thickness. Its design targets recurring pain points in the wrapping process: adhesive residue contaminating wrapped goods and equipment; low-transparency film blocking barcode scanning; excess film consumption raising material cost and waste; breakage at sharp corners; unstable unwinding on high-speed lines; and persistent plastic waste.
One disclosure matters for procurement teams: ZeRoll®'s biodegradable positioning is a positioning statement. Specific biodegradation or compostability claims must correspond to the applicable product, supporting documentation, standard, and specified end-of-life conditions — a framing that becomes decisive when a film is compared across regions with different end-of-life rules.
Mechanical Performance at 0.022 mm Thickness
At 0.022 mm thickness, ZeRoll® stretch film reports tensile strength of approximately 50–52 MPa in the machine direction (MD) and approximately 35–40 MPa in the transverse direction (TD). For reference, peer-mainstream films report approximately 40–45 MPa MD and 20–25 MPa TD, while traditional PE reports 35–40 MPa MD and 20–25 MPa TD. Longitudinal strength is increased by about 20% versus the peer-mainstream reference at 0.022 mm.
Elongation at break reaches approximately 620–700% MD and approximately 840–880% TD, supporting adaptation to a wide range of goods and to automated winding. Tear strength reaches approximately 110–120 kN/m MD and approximately 120–130 kN/m TD, against approximately 85–95 kN/m MD and 125–135 kN/m TD for peer-mainstream films and 60–80 kN/m MD and 80–100 kN/m TD for traditional PE. MD tear-strength increase is approximately 30% versus the peer-mainstream reference at 0.022 mm — the property that reduces breakage at sharp corners.
Elastic recovery is approximately 70%, compared with approximately 50% for conventional stretch films, and this is the mechanism behind keeping goods tightly wrapped during transport. Optical properties support scanning and inspection workflows as well: transmittance of approximately 85–90% allows clear barcode identification, with haze at approximately 20–24%.
Comparisons with traditional PE should be based on the stated ranges in the comparison table rather than on the percentage figures. Test basis: internal test results and average values from publicly available industry samples, provided for performance comparison only; specific parameters are subject to the testing of contract samples.
Tackiness Control and Material Efficiency
Self-adhesion — the property that holds one film layer to the next — is approximately 1.3–1.6 N/cm², against approximately 1.4–7 N/cm² for peer-mainstream films and approximately 1.0 N/cm² for traditional PE. Tackiness is adjustable from 0.8 N to 6.5 N, offering broader application options and a clean peel without residue, so wrapped goods and equipment stay free of adhesive residue after unwrapping. Even self-adhesion and a clean surface after peeling are the features behind that claim.
Material efficiency is the second lever. The film is positioned to deliver the same wrapping performance with less film usage, which helps customers manage long-run material and disposal costs and strengthen environmental, social, and governance positioning.
Three technical elements underpin these results: polymer material modification technology, which supports development of the ZeRoll® biodegradable stretch-film material system; a multi-layer co-extruded structure that improves puncture resistance; and a special tack-enhancing formula that delivers the adjustable tack range.
Equipment Compatibility Across Wrapping Lines
SYNLIFE develops stretch-film solutions for manual, semi-automatic, and automatic pallet-wrapping applications, and machine stretch-film solutions have demonstrated stable use on automatic wrapping equipment at up to 3× pre-stretch. Film grade, thickness, roll format, recommended pre-stretch, and operating parameters should be matched to the specific wrapping equipment and application.
In practice, uniform thickness, smooth edges, and seamless unwinding support high-speed and fully automatic winding equipment, while smooth winding and lower noise improve packaging-line working conditions. Roll stability — uniform thickness, smooth edges, and unwinding without jamming — is the feature that carries the machine-stability benefit.
Delivery follows the same logic: stretch-film solutions are supplied as roll stock for different wrapping applications, as physical rolls for manual, semi-automatic, and fully automatic stretch-wrapping equipment.
Third-Party Documentation: What Is Certified and What Is Not
Two documents accompany the product line.
- DIN-Geprüft Registration No. 9K0326, valid until September 30, 2031, tested under DIN EN 13432:2000-12. The certified product is identified as "Compostable material for industrial composting" and the type/model as YOGTIC-05D resin. Certification body: DIN CERTCO Gesellschaft für Konformitätsbewertung mbH.
- SGS Test Report No. SHMR231202421931-1_CN, dated March 08, 2024, which may only be cited for the specific test scope and results contained in that report.
Both are material-level documents covering industrial composting. They must not be presented as certification of the finished ZeRoll® stretch film unless the finished film is explicitly covered by the applicable certificate scope. Stating this boundary up front is what makes the documentation usable in a due-diligence review rather than a liability.
Where ZeRoll® Stretch Film Fits
- Logistics and Warehousing: pallet packing and warehousing/sortation centers.
- Manufacturing: transportation of industrial products.
- Food & Beverage: secondary and tertiary pallet-wrapping and transport-packaging applications; the film is not positioned as a direct food-contact film.
- Agriculture: an alternative to traditional plastic wrap.
- Export Packaging: protection for export goods.
- Automated Packaging Lines: compatible with automated wrapping lines.
Practical Takeaways for Packaging Buyers
A logistics packaging film has to contain a load, survive corners, run cleanly on the line, and satisfy the receiving customer's packaging requirements. ZeRoll® addresses the first three with measurable mechanical data at 0.022 mm thickness and an adjustable tack range of 0.8 N to 6.5 N, and the fourth with documented material-level industrial composting credentials whose scope is stated plainly. For buyers evaluating stretch film for logistics packaging, the sensible next step is verification through contract-sample testing, since specific parameters are subject to the testing of contract samples.
