Plastic is currently used in a wide range of food packaging materials, it is a high molecular polymer, composed of a variety of additives added to the polymer resin, has the advantages of convenient transportation, light weight, easy processing, good food protection, etc. 60% of food packaging uses plastic as packaging material. This article will introduce you to the current status of smart packaging materials. As one of the landmark industries for the development of commodity economy, the packaging industry has played an active role in promoting the healthy and sustainable development of the national economy and is a major component of the national economy. The main purpose of China's current development of circular economy is to reduce capital consumption and maintain the ecological environment of the earth. Degradable green packaging material refers to degradable plastic packaging. If it is randomly discarded on the ground, it can be degraded and reduced in nature, not like polyethylene and polyvinyl chloride in plastic. The environment causes serious harm. The waste of resources caused by disposable packaging materials is an unavoidable reality in front of each of us. The technological innovation of disposable packaging materials and the research and development of environmentally friendly packaging materials are the main tasks we will do next. Maintaining the ecological environment, developing a circular economy, and using green packaging materials is what we should do. Due to the complexity of the composition of the packaging material, the precipitation of substances in the food packaging material occurs in the food, possibly due to the migration of these substances to the food, or in the food due to accidental extraction. This causes chemical migration of food packaging to have a negative impact on food.
