The work aims to study the main problems of takeout package under O2O platform and provide suggestions and countermeasures for the improvement and development of takeout package. In the method of literature analysis and Internet survey, the status quo of takeout package under O2O platform and the existing problems were collected, and the corresponding solutions thereto were explored with respect to the attribution analysis for each problem. For the plastic takeout package, only PP polypropylene materials could be used for the high temperature of about 200 ℃, which could be used for hot food. Other plastic packages would release toxic substances due to high temperature and thus affected the health. More than 70% of the packaging design was simple and the soup was easy to spill. More than 60 million takeout boxes and 1.2 billion square meters of plastic bags used per day severely polluted the environment. There was no corresponding standard for the takeout package. Under O2O platform, the takeout package results in prominent health risks and insufficiently humanized deign, lacks unified standards, and causes severe environmental pollution and other problems. The packaging materials should be chosen carefully, the industry self-discipline and external supervision should be strengthened, the use of inferior lunch box and disposable tableware should be reduced, and the packaging design should be improved, so as to accelerate the national legislation and establish a mechanism for the recycling of packaging waste.
