With the development of science and technology, food packaging materials have a complicated phenomenon, some materials are mixed into blends and copolymers; and some food packaging materials in the process of adding recycling of waste materials, such materials the infrared absorption band position is very close, and often overlap, mutual interference, it is difficult to judge also, the thermal properties change with the fraction. Therefore, only one technique can not be used to identify it accurately, and the combination of IR-DSC technique (infrared absorption spectroscopy and thermal analysis) can meet the requirement of analysis.

PVC fresh film the main harm is the residual vinyl chloride monomer on the human body has carcinogenic effects, by using infrared absorption peaks of the functional characteristic of fresh film can be measured quickly and efficiently in PE film and PVC film [6]. Some manufacturers in the cost of packaging materials in the process of adding recycled materials, reducing the quality of products, endanger consumer safety. The DSC test is used to further differentiate and identify. Through the DSC melting point test curve, we can infer that the recycled polyethylene particles may contain a small amount of polypropylene and other impurities.
