s the critical starting point of our PVC film production chain, the PVC Film Production Raw Material Storage Warehouse is engineered to uphold the highest standards of preservation, organization, and safety—ensuring the integrity and stability of raw materials that directly define the quality of our end products.​ Spanning 3,800 square meters of dedicated storage space, the warehouse is designed with classified storage zones to accommodate diverse raw materials: separate compartments for food-grade virgin resin, recycled resin, functional additives (antistatic agents, flame retardants, degradable modifiers), and auxiliary materials (pigments, stabilizers). Each zone is equipped with specialized environmental control systems: the resin storage area maintains a constant temperature of 15-20℃ and relative humidity below 50% to prevent moisture absorption and agglomeration, while additive storage zones feature sealed cabinets with moisture-proof and light-shielding functions to preserve chemical stability.​ To eliminate contamination risks, the warehouse adopts an ISO 8 Class clean storage standard, with dust-free flooring, high-efficiency air filtration systems, and regular particle count monitoring. Anti-static measures are comprehensively implemented—including anti-static grounding for storage racks, ionizers in resin handling areas, and electrostatic discharge (ESD) protection for additive packaging—to avoid static-induced hazards and material degradation.
