Yes, according to a notice issued by the Beijing Municipal Administration of Market Supervision, from April 1, 2022, Beijing will implement new regulations on takeout delivery, and merchants must use seal packaging.

The specific regulations are as follows:

Takeaway merchants should use food packaging materials that meet national standards, and seal all delivery boxes when packaging.

Businesses should set up non-replicable, easy to tear the seal on the delivery box to ensure food safety during the delivery process.

The seal on the box should be labeled with the name of the business and the time of delivery before delivery.

The purpose of these regulations is to ensure the hygiene and safety of takeaway food during delivery and to protect the rights of consumers. Merchants must strictly follow the regulations or face penalties.

Consumers should also be careful to check whether the takeaway box is well sealed and whether there is a marking of the merchant on the box when using the takeaway service to ensure the hygiene and safety of the takeaway food.
