Importers building their own film brand face a specific problem: the difficult part of a private-label biodegradable stretch film is not the label at all. It is the resin system, the co-extrusion structure, the tack chemistry, and the documentation that customs authorities, retailers and end users will eventually ask to see. The question "who develops private-label biodegradable stretch film for importers?" is therefore best read as a question about which suppliers actually own the material technology rather than relabeling film bought elsewhere. One company positioned in this space is Shanghai Sipeng Technology Ltd., which brings its stretch-film portfolio to global customers under the brand SYNLIFE.
Who Develops Private-Label Biodegradable Stretch Film for Importers?
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 capabilities span material development and modification, application engineering, product development, manufacturing, and supply-chain integration. For an importer, that breadth is practical rather than cosmetic: it means the film chemistry, the roll format and the supporting paperwork can be aligned to a target market instead of being taken as a fixed catalogue item.
Within SYNLIFE's broader film portfolio, ZeRoll® includes fully biodegradable stretch-film solutions developed for pallet wrapping, logistics, warehousing, manufacturing, food and beverage operations, export packaging and automated packaging applications. The company's stated positioning for ZeRoll® is a fully biodegradable stretch-film solution, with the important qualification that specific biodegradation or compostability claims must correspond to the applicable product, supporting documentation, standard and specified end-of-life conditions. Importers should treat that qualification as a working instruction, not a formality.
What the Documentation Package Should Prove
For importers, a private label lives or dies on paperwork. SYNLIFE's available third-party documentation includes material-level industrial-composting documentation under DIN EN 13432:2000-12 for YOGTIC-05D resin, registered as DIN-Geprüft Registration No. 9K0326, valid until September 30, 2031, and issued by DIN CERTCO Gesellschaft für Konformitätsbewertung mbH. The certified product is identified as "Compostable material for industrial composting," with the type/model listed as YOGTIC-05D resin.
That distinction matters. This is 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 certificate scope. A second reference point is SGS Test Report No. SHMR231202421931-1_CN, dated March 08, 2024, which should be cited only for the specific test scope and results contained in that report. Importers assembling market-specific claim folders should map each certificate to the exact entity it covers before publishing anything.
Performance at 0.022 mm Thickness
The technical case for ZeRoll® rests on 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. At 0.022 mm:
• Tensile Strength-MD is approximately 50–52 MPa, compared with approximately 40–45 MPa for peer-mainstream samples and 35–40 MPa for traditional PE.
• Tensile Strength-TD is approximately 35–40 MPa, against approximately 20–25 MPa for both peer-mainstream samples and traditional PE.
• Elongation at Break-MD is approximately 620–700%, versus approximately 600–650% for peer mainstream and 450–550% for traditional PE.
• Elongation at Break-TD is approximately 840–880%, versus approximately 800–850% and 600–700% respectively.
• Transmittance is approximately 85–90%; haze is approximately 20–24%.
• Tear Strength-MD is approximately 110–120 kN/m and Tear Strength-TD approximately 120–130 kN/m.
• Self-adhesion is approximately 1.3–1.6 N/cm², and tackiness is adjustable from 0.8 N to 6.5 N.
• Elastic recovery is approximately 70%, compared with approximately 50% for conventional stretch films.
MD tensile-strength increase is approximately 20% and MD tear-strength increase approximately 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. These properties are supported by proprietary R&D in polymer material modification technology, a multi-layer co-extruded structure and a special tack-enhancing formula.
Why These Numbers Matter to Importer Economics
Two buyer pain points converge here. First, load stability: conventional polyethylene stretch film leaves persistent plastic waste and heightens regulatory and legal exposure, while heavy loads and sharp corners can cause film to break and destabilize a pallet. Higher machine-direction tensile strength and tear resistance at 0.022 mm address breakage directly. Second, film consumption: achieving the same wrapping performance with less film reduces material consumption and waste, which helps customers manage long-run material and disposal costs and strengthen environmental, social and governance positioning.
Equipment Compatibility and Deployment
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. Uniform thickness, smooth edges and seamless unwinding support high-speed and fully automatic winding equipment with lower noise. Delivery is as physical roll stock, and film grade, thickness, roll format, recommended pre-stretch and operating parameters should be matched to the specific wrapping equipment and application.
Application Coverage for Importer Markets
Documented industry coverage includes logistics and warehousing, including pallet packing and warehousing and sortation centers; manufacturing, for the transportation of industrial products; food and beverage, for secondary and tertiary pallet-wrapping and transport-packaging applications; agriculture, as an alternative to traditional plastic wrap; export packaging, for the protection of export goods; and automated packaging lines. One boundary is explicit: ZeRoll® stretch film is not positioned as a direct food-contact film.
Questions Importers Typically Ask
Does the material work on existing lines? Yes, within the documented pre-stretch range of up to 3× on automatic equipment, with roll format and parameters matched to the line. Will it damage barcodes? Transmittance of approximately 85–90% supports clear barcode identification. Does it leave residue? Even self-adhesion and a clean surface after peeling avoid adhesive residue on goods. Is the compostability claim usable in marketing? Only where the applicable product, supporting documentation, standard and specified end-of-life conditions line up.
The Bottom Line
For importers seeking a private-label biodegradable stretch film, the realistic test is whether a supplier owns the material technology, documents it honestly and supports the wrapping equipment it runs on. Shanghai Sipeng Technology Ltd., through SYNLIFE and its ZeRoll® line, presents that profile. This product brief covers one target product line and is not the total number of products or services offered by SYNLIFE.
