273 batches of food contact materials and products with 8 materials were selected to determine suitability, water sensitivity and total migration of olive oil, and the detection risks of different food contact materials were analyzed. The results showed that in terms of suitability determination, the unqualified rate of PVC material suitability was 100%. The suitability of PE, PET, vinyl chloride - vinylidene chloride copolymer resin and paper aluminum plastic cover film material was determined. For TPE, PP and metal coating materials, due to the interference of additives, the suitability of the judgment part did not pass. In terms of water sensitivity, PET material and paper aluminum-plastic cover film samples were moisture sensitive samples, the probability of water conditioning was 100%. As for TPE material, the probability of water conditioning is 48% due to additives exposure time and other factors, while other materials did not need water conditioning. In terms of migration test detection, the detection risks of TPE, PP and paper aluminum-plastic cover film were higher, which were 86%, 58% and 50%, respectively. The detection rates of PE, PET and metal coating materials were 7%, 9%, 9%, with a certain detection rate, but the overall migration risk was not high, while vinyl chloride - vinylidene chloride copolymer resin film material with correction factor could meet the limit requirements. Before the migration test, priority should be given to the suitability determination, moisture sensitivity confirmation and adjustment to ensure the accuracy and validity of test results, and to provide data support for the safety management and quality control of food contact materials and products.
