Abstract
The invention discloses a polypropylene-blended soft infusion bag and a preparation method thereof. The polypropylene-blended soft infusion bag is characterized in that a bag body and an interface formed in the top end of the bag body are formed at one step, and the soft infusion bag is prepared by blending a medical polypropylene copolymer, a styrene-ethylene/butylene-styrene copolymer or a hydrogenated styrene-isoprene-butadiene block copolymer. The preparation method comprises the steps of firstly, carrying out injection molding to form a bag blank; and then, carrying out two-way stretching and blow molding to form a blow-molded medical bag. By using the preparation method, defects of a non-pvc infusion bag are overcome, the raw material of the medical bag does not depend on a foreign non-pvc film any more, and the diversification of the preparation raw material is realized; meanwhile, the bag and the interface are formed at one step, so that the problems of liquid leakage and pollution caused by secondary welding of a non-pvc soft bag and the interface are avoided; and compared with the existing medical bag, the polypropylene-blended soft infusion bag is more transparent, more flexible, low in cost and high in qualified finished product rate and is more adapted to industrial production.
