摘　　要：通过挤出吹膜的方法制备PBSA/TPS淀粉基生物降解塑料,研究了不同风环结构及吹胀比和牵引比对于吹膜及性能的影响。结果表明:双风口风环可以极大提高PBSA/TPS材料的吹膜膜泡稳定性,而随着吹胀比和牵引比的增大,薄膜的拉伸强度。Producing PBSA/TPS film sampls by blown film,research the influence of different type air-ring,blow-up ratio and draw-down ratio on blown film processability and film properties.It is showed that：dual-lip air-ring is able to increase PBSA/TPS blown film bubble stability,and tentile strength, elongation at break and tear resistance of film increase initially and decrease afterwards as increasing of BUR and DDR.
