Objective To introduce the recent development and innovation of food packaging and food safety problems under new technology conditions. Methods Working principles of new food packaging technology and its application in food industry were analyzed, including the function of intelligent packaging technology and active packaging technology in preserving food quality and guaranteeing food safety. The working principle of environmental protection material and edible materials and their functions of environment protection were described. And food safety problems under new technology condition including the effect of harmful substance in different packing materials on food safety, and the problems of material degeneration of packing materials due to environmental change like heating or radiation were discussed. Results With the application of new technologies and new materials, new types and functions of food packaging have been emerging and it also plays an active role in environment protection. However, the appearance of new food packing materials has caused some new problems of food safety like the migration of harmful substances. Conclusion More solid work needs to be done in the field of food packaging to diversify the types of packaging, guarantee food safety, reduce the harmful substances and improve the stability of the packed products.
