针对制备玉米秸秆缓冲包装材料的11个工艺参数，以材料的强度为响应目标，采用Plackett-Burman（PB）与Central Composite Design（CCD）相结合的方法进行筛选优化。PB实验设计与分析表明：纤维粒度、纤维目数与胶粘剂含量为制备工艺的3个关键因素。经过CCD设计及响应面法优化分析得到的制备玉米秸秆纤维缓冲包装材料的最优条件为:纤维粒度224.62目，纤维体积分数22.78%，胶粘剂质量分数35%，材料强度可达1.758 MPa。

Plackett-Burman (PB) design and central composite design (CCD) were combined to optimize 11 technological parameters for preparation of corn stalk fiber cushioning materials. PB design and analysis showed that the three key factors, fiber granularity, fiber content and adhesive content are significant for preparation of corn stalk fiber cushioning material. CCD design and response surface analysis showed that the optimal preparation conditions is fiber granularity 224.62, fiber volume fraction 22.78% and adhesive mass fraction 35%; the strength of the prepared material is 1.758 MPa.
