The invention relates to a self-shrinking infusion bag and a special material therefor. The special material comprises medical-grade high-temperature-resistant polypropylene, medical-grade polyolefin elastomer, antioxidant and acid scavenger. The manufacturing process includes weighing according to the formula, mixing raw materials, extruding and pelletizing via a twin-screw extruder, circulating water cooling, air drying and mechanical pelletizing. The addition of POE elastomer improves the flexibility of the infusion bag, providing self-shrinking function for elliptical cross-section bags produced by injection, stretching or blow molding. The bag body prepared from the material has no welding seams, greatly reducing the risk of liquid leakage.
