Abstract

The invention belongs to the technical field of analysis and detection and in particular relates to a method for detecting organic matters in a packaging material. The method provided by the inventionand used for detecting the organic matters in the packaging material comprises the following steps: detecting a packaging material sample by adopting static headspace balance and gas chromatography-mass spectroscopy, thus obtaining gas chromatography data and mass spectroscopy data; and according to a standard curve of gas chromatography data as well as mass spectroscopy data of organic matter standard solution, obtaining contents of the organic matters in the packaging material, wherein the organic matters comprise one or more of 5-methyl heptane, n-pentadecane, n-hexadecane and n-heptadecane. The method provided by the invention can detect the contents of 5-methyl heptane, n-pentadecane, n-hexadecane and n-heptadecane in the packaging material sample at the same time, and the method issimple, rapid, accurate, good in repeatability and high in accuracy.

Description

technical field [0001] The invention belongs to the technical field of analysis and detection, and in particular relates to a method for detecting organic matter in packaging materials. Background technique [0002] Packaging is the image endorsement of products and plays an extremely important role in marketing, such as food, cosmetics and cigarette packaging boxes can affect consumers' first emotions. With the continuous improvement of consumer demand and the fierce development of market competition, the appearance of packaging boxes is becoming more and more exquisite, and the quality requirements for appearance are also getting higher and higher. [0003] The packaging box is mainly formed by packaging materials through packaging machine packaging BOPP (Biaxially Oriented Polypropylene, biaxially oriented polypropylene) film. There are many packaging boxes designed with dark packaging paper on the market. This type of packaging box is prone to "water mist" appearance de...
