LLDPE Liner

We structure our MOQ to support both immediate project needs and large-scale engineering demands.

For standard stock specifications: The MOQ is typically just 1 roll. We maintain a strategic inventory of standard sizes to support urgent repairs, pilot projects, or small-scale applications.

For custom thicknesses, widths, or colors: The MOQ is usually one 20ft container. Custom manufacturing requires specific machine calibration and material transition times. Producing at a container volume ensures consistent quality control across the batch while minimizing production waste, which ultimately allows us to offer you the most competitive factory-direct pricing.

Absolutely. As a direct manufacturer operating state-of-the-art extrusion lines, we offer high flexibility in dimensions to optimize your project.

Width: We can manufacture LLDPE liners in widths up to 8.0 meters (26.2 feet). Utilizing wider rolls significantly reduces the number of field welding seams required, which not only accelerates installation time but also minimizes the risk of potential leak points.

Length: Roll lengths are fully customizable. Our technical team routinely calculates the optimal roll length based on your specific site dimensions and container loading capacities (e.g., maximizing the payload of a 40ft HC container). This custom sizing ensures you do not pay for shipping "empty space," directly reducing your landed freight costs per square meter.

Quality and long-term performance are our strict priorities. We exclusively use 100% virgin high-quality polyethylene resin.

Our LLDPE geomembrane formulation strictly adheres to the GRI-GM17 standard. The composition is typically 97.5% premium virgin polymer, combined with approximately 2.5% highly dispersed carbon black, antioxidants, and UV stabilizers. We never use recycled materials, regrind, or off-spec resins. Using 100% virgin material is critical for ensuring superior Multiaxial Elongation, excellent Environmental Stress Crack Resistance (ESCR), and a lifespan that can exceed decades in demanding geotechnical environments. Every batch comes with a Certificate of Analysis (COA) for full traceability.

We pride ourselves on reliable and transparent supply chain management.

Standard Orders: For standard specifications, our typical lead time is 7 to 14 days from the receipt of your deposit.

Large or Custom Orders: For mega-projects or highly customized specifications, the timeline will be confirmed during the quoting process.

Our ISO 9001-certified facility operates multiple high-capacity production lines 24/7. This robust manufacturing capacity ensures that even during peak construction seasons, we can meet strict project deadlines without ever compromising on our rigorous Quality Assurance/Quality Control (QA/QC) protocols.

Every single roll undergoes rigorous testing in our in-house, state-of-the-art QA/QC laboratory before it is cleared for shipment. We test strictly according to ASTM standard test methods (such as ASTM D5199 for thickness, ASTM D6693 for tensile properties, and ASTM D1004 for tear resistance). We verify thickness consistency, elongation at break, puncture resistance, and carbon black dispersion. We can also accommodate third-party testing inspections (such as SGS, Intertek, or TUV) prior to loading upon request.

While both are excellent containment barriers, Linear Low-Density Polyethylene (LLDPE) offers superior flexibility and multi-axial elongation compared to High-Density Polyethylene (HDPE). We highly recommend our LLDPE liners for projects where the subgrade is uneven, where differential settlement is expected (such as landfill capping or mining closures), or for applications requiring complex detailing and folding. Our engineering team can help you select the exact polymer type based on your specific site conditions.

We understand that the integrity of the liner must be maintained from our factory floor to your job site. Each roll is tightly wound on a high-strength core to prevent crushing. The exterior is wrapped in a heavy-duty, UV-resistant woven bag to protect against abrasion and sunlight during transit and temporary site storage. Furthermore, every roll is equipped with reinforced lifting straps (slings) at both ends to ensure safe and easy unloading using a forklift or crane without puncturing the material.

Yes. We understand that proper installation is just as critical as material quality. Our LLDPE liners are designed for excellent weldability using standard hot wedge welders and extrusion welding equipment. We provide comprehensive technical installation manuals with every order. For large-scale or complex international projects, we can also dispatch experienced technical supervisors to your site to train your local crews and oversee the initial deployment and welding procedures.

When properly installed and maintained, our 100% virgin LLDPE liners offer exceptional longevity. In covered applications (e.g., buried under soil or water, protected from direct UV exposure), the lifespan can easily exceed 50 to 100 years. For exposed applications, our premium UV stabilizer package ensures a functional life of decades, depending on the specific climate, UV index, and chemical exposure of your site. We offer project-specific warranties to guarantee your investment.

We usually support trial orders starting from 1–3 tons for regular specifications. For export shipments, we generally recommend at least 1 × 20GP container, as container loading usually offers a more competitive cost per square meter. For customized thickness, width, or roll length, the MOQ may be higher depending on production scheduling and order arrangement.

We control UV performance through raw material selection, additive formulation, and batch-based quality control. Raw materials are checked carefully before production, and finished products are tested in our laboratory before shipment. For geotextile products, we also pay close attention to UV durability and flow performance to ensure they are suitable for outdoor engineering applications.

Yes. We provide Technical Data Sheets (TDS) and can also support product test data for project evaluation. Depending on the order and specification, the documents may include thickness, tensile properties, puncture-related indicators, and other key technical values required for approval and procurement review.
