HDPE (High-Density Polyethylene) features a highly crystalline structure with minimal polymer branching, delivering high tensile strength, stiffness, and heat resistance. It forms the woven mesh base in high-strength applications. LDPE (Low-Density Polyethylene) has extensive long-chain branching, providing high clarity, flexibility, and easy melt processing. LLDPE (Linear Low-Density Polyethylene) features short, uniform branches that offer superior puncture resistance, flex-crack endurance, and elongation at break. In our factory, we co-extrude LLDPE and LDPE over a high-tenacity woven HDPE core to achieve an optimal balance of structural strength and hermetic waterproofing.
Unprotected polyethylene degrades rapidly under solar ultraviolet (UV) radiation due to photo-oxidation, leading to embrittlement and strength loss. We incorporate 3% to 5% high-grade Hindered Amine Light Stabilizers (HALS) alongside carbon black or UV-326 absorbers during the polymer tape extrusion process. This masterbatch formula captures free radicals generated by UV light, extending the product’s outdoor operational lifetime up to 3–5 years even under harsh Middle Eastern, Australian, or African solar radiation levels.
For standard warehouse roll stock specifications, our MOQ starts at a flexible mixed-container load (20ft container). For fully customized OEM products—including specific fabric GSM, custom color masterbatches, UV additives, surface flexographic logo printing, and retail packaging headers—the minimum order requirement is typically 3 metric tons per specification. Standard production lead time is 15 to 25 calendar days following artwork confirmation and pre-production sample approval.
Every production lot undergoes rigorous laboratory verification before container loading:
1. Tensile & Elongation Testing (ISO 13934-1): Verifying warp and weft breaking strength.
2. Dart Drop Impact Test (ASTM D1709): Checking resistance to sudden blunt force impact.
3. Hydrostatic Head Pressure Test (AATCC 127): Confirming continuous water impermeability exceeding 150 kPa.
4. Thermal Seam Weld Peel Strength: Ensuring heat-sealed hems do not split under load.
Batch Inspection Certificates (COA) and photo/video audit reports are provided to international clients prior to vessel departure.
Yes. To help importers navigate EU Plastic Packaging Tax mandates and global sustainability frameworks, we offer GRS-certified (Global Recycled Standard) PE bag and tarpaulin formulations containing between 30% and 70% Post-Consumer Recycled (PCR) or Post-Industrial Recycled (PIR) polyolefin content. Our advanced extrusion lines ensure these eco-friendly bags maintain strict structural integrity and puncture resistance.
