摘　　要：目的:建立双向拉伸聚丙烯/真空镀铝流延聚丙烯复合膜的近红外光谱快速鉴别方法。方法:采用近红外光谱仪,对26批复合膜的正、反面光谱分别建立聚类分析、一致性检验及相关系数模型。结果:通过聚类分析与一致性检验,参考样品与验证样品得到了很好的区分;通过相关系数分析,参考样品相关系数均在阈值98%以上,不同材质的验证样品相关系数均低于阈值98%。结论:通过采用其他4种不同材质样品,包括双向拉伸聚丙烯/聚酯/聚乙烯复合膜、聚酯/镀铝/聚乙烯复合膜、聚酯/镀铝聚酯/聚乙烯复合膜、非参考样品材质的复合膜样品,对模型的验证结果来看,本方法快速、准确,可用于对双向拉伸聚丙烯/真空镀铝流延聚丙烯材质复合膜的快速筛查。Objective： To establish a rapid identification method of near infrared spectrum of two-way stretch polypropylene/vacuum aluminum plating cast polypropylene composite membrane （thereinafter were named reference samples）. Methods： The clusting analysis, consistency test and correlation coefficient model of the positive and reverse spectrums of the 26 batches composite membrane were set up by using the near infrared spectrometer. Results： The reference samples and the verification samples was well sorted by using the clusting analysis and consistency test. The correlation coefficient of reference samples was above 98% of the threshold value by using correlation coefficient analysis. The correlation coefficiertt of different verification samples was below 98% of the threshold value. Conclusion： This method was rapid, accurate and could be used for rapid screening of the two-way stretch polypropylene / vacuum aluminum plating cast polypropylene composite membranes based on the verification results of the model using four different samples, including two-way stretch composite membrane, polyester / aluminized / polyethylene composite membrane, polypropylene / Polyester / PE composite membranei polyester/aluminized / polyethylene composite membrane,polyester/aluminum plated polyester/PE composite membrane, and a composite membrane of non reference sample material （batch number 1116）.
