The present invention provides a safe storage container for blood or blood components and a preparation method thereof. The storage container comprises a storage bag and a tube; the storage bag is made of polyurethane/polyvinyl chloride double-layer composite tubular film; the tube is made of polyurethane/polyvinyl chloride double-layer composite tube; the inner layer of the polyurethane/polyvinyl chloride double-layer composite tubular film is made of polyurethane and the corresponding outer layer is polyvinyl chloride; the inner surface of the polyurethane/polyvinyl chloride double-layer composite tube is a polyurethane layer and the outer surface is a polyvinyl chloride layer. The polyurethane/polyvinyl chloride double-layer composite tubular film is prepared by co-extrusion blow molding, and the polyurethane/polyvinyl chloride double-layer composite tube is obtained by co-extrusion. The storage container has excellent blood compatibility, avoids contamination of blood by small molecules such as phthalate plasticizers, meets thermal sterilization requirements in heat resistance, has high mechanical strength, is easy to bond, suitable for high-frequency welding, and low in manufacturing cost.
