摘　　要：为了建立一种简便快速无损的检验快递塑料包裹袋的分析方法,利用傅里叶变换红外光谱仪,采用Smart Performer采样器,对不同快递公司的55个快递塑料包裹袋样品进行了分析检验。依据红外光谱图中特征吸收峰的不同,可以将快递塑料包裹袋样品进行区分。该检验方法操作简便快捷,重现性好,结果准确可靠且无损检材,可用于公安基层实际办案。A simple, fast and nondestructive method for the analysis of express plastic packaging bag was established. Using the Fourier infrared spectrometer and the Smart Performer sampler, 55 samples of express plastic bags from different express companies were analyzed and tested. According to the difference of characteristic absorption peak in infrared spectrogram, the samples of express plastic bag can be distinguished. This method is simple and quick to operate, good reproducibility, accurate and reliable results and nondestructive inspection materials, which can be used in the practical case hand- ling of the public security base.
