Custom Shipping Stretch Film Review: SYNLIFE ZeRoll Data

Why Custom Shipping Stretch Film Buyers Are Reassessing Their Options

Buyers searching for a custom shipping stretch film manufacturing partner typically arrive with the same set of constraints: load containment that holds through transit, film that survives sharp corners, throughput that matches automated wrapping lines, and a defensible answer to the plastic waste and regulatory exposure question. ZeRoll® Fully Biodegradable Stretch Film, developed by Shanghai Sipeng Technology Ltd. under the SYNLIFE brand, is positioned directly against that brief. This review walks through the documented specifications, the third-party documentation behind the product, and the application scope that determines whether it fits a given wrapping operation.

Who Manufactures ZeRoll®: SYNLIFE at a Glance

Shanghai Sipeng Technology Ltd. operates under the brand name SYNLIFE and is headquartered at Building 4, No. 878, Jianchuan Road, Minhang District, Shanghai, China.

Corporate positioning: SYNLIFE is 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 — a combination that matters to buyers who need film matched to a specific machine and load rather than a fixed catalog item.

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.

The Operational Pain Points ZeRoll® Is Built to Address

• Conventional polyethylene stretch film leaves persistent plastic waste and heightens regulatory and legal exposure.
• Heavy loads and sharp corners can cause wrapping film to break and destabilize a pallet.
• Automated packaging lines require stable unwinding, high-speed compatibility, and low operating noise.
• Low-transparency film can block barcode scanning.
• Adhesive residue can contaminate wrapped goods and equipment.
• Excess film consumption raises material cost and waste volume.

Technical Performance at 0.022 mm Thickness

The published performance envelope is stated at 0.022 mm thickness, with peer-mainstream and traditional PE reference ranges noted for context:

• Tensile Strength-MD: approximately 50–52 MPa; peer mainstream approximately 40–45 MPa; traditional PE 35–40 MPa.
• Tensile Strength-TD: approximately 35–40 MPa; peer mainstream approximately 20–25 MPa; traditional PE 20–25 MPa.
• Elongation at Break-MD: approximately 620–700%; peer mainstream approximately 600–650%; traditional PE 450–550%.
• Elongation at Break-TD: approximately 840–880%; peer mainstream approximately 800–850%; traditional PE 600–700%.
• Tear Strength-MD: approximately 110–120 kN/m; peer mainstream approximately 85–95 kN/m; traditional PE 60–80 kN/m.
• Tear Strength-TD: approximately 120–130 kN/m; peer mainstream approximately 125–135 kN/m; traditional PE 80–100 kN/m.
• Transmittance: approximately 85–90%; peer mainstream approximately 85–95%; traditional PE 80–85%.
• Haze: approximately 20–24%; peer mainstream approximately 10–15%; traditional PE 20–30%.
• Self-Adhesion: approximately 1.3–1.6 N/cm²; peer mainstream approximately 1.4–7 N/cm²; traditional PE approximately 1.0 N/cm².

Additional documented figures include elastic recovery of approximately 70%, compared with approximately 50% for conventional stretch films, and adjustable tackiness from 0.8 N to 6.5 N. Longitudinal strength is increased by about 20% and tear resistance by about 30% versus the peer-mainstream reference at 0.022 mm. Comparisons with traditional PE should be based on the stated ranges rather than these percentage figures.

The underlying technology platform rests on polymer material modification technology, a multi-layer co-extruded structure that improves puncture resistance, and a special tack-enhancing formula that delivers the adjustable tack range. Test basis: 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.

Third-Party Documentation and How It Should Be Read

Two documents are cited in the available material, and both carry defined scope:

• DIN-Geprüft Registration No. 9K0326, tested under DIN EN 13432:2000-12 and valid until September 30, 2031. The certified product is identified as "Compostable material for industrial composting" with the type/model listed as YOGTIC-05D resin. Certification body: DIN CERTCO Gesellschaft für Konformitätsbewertung mbH. This is material-level documentation for the resin and must not be presented as certification of the finished ZeRoll® stretch film unless the finished film is explicitly covered by the certificate scope.
• 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.

On the biodegradability positioning itself, the applicable framing is that specific biodegradation or compostability claims must correspond to the applicable product, supporting documentation, standard, and specified end-of-life conditions.

Equipment Compatibility and Delivery Model

SYNLIFE develops stretch-film solutions for manual, semi-automatic, and automatic pallet-wrapping applications. 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. Solutions are supplied as physical roll stock for manual, semi-automatic, and fully automatic stretch-wrapping equipment.

Where the Film Applies

• 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. ZeRoll® stretch 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.

How to Vet a Custom Stretch Film Partner

1. Match the specification to the machine. Confirm film grade, thickness, roll format, and recommended pre-stretch against the actual wrapping equipment.
2. Request contract-sample testing. Published ranges are comparison data; final parameters follow sample testing.
3. Verify certificate scope. Check whether a compostability certification covers the specific material or the finished film, and confirm the stated end-of-life conditions.
4. Test the corner cases. Sharp-corner puncture, heavy-load stability, and barcode readability are the failure modes most likely to appear on a live line.

Summary Assessment

For buyers prioritizing load stability, tear resistance, elastic recovery of approximately 70%, and clean peel without residue, ZeRoll® presents a documented technical profile at 0.022 mm along with material-level industrial-composting documentation under DIN EN 13432:2000-12. The material also addresses common line-level friction points — material saving, barcode readability at approximately 85–90% transmittance, and stable unwinding on high-speed and fully automatic winding equipment. Buyers should treat certification scope and contract-sample testing as the deciding factors.
