According to the latest national standard GB 4806.1-20 16 "General Safety Requirements for Food Contact Materials and Products".

Product identification information shall be clear and true, and shall not mislead users. Products should provide sufficient product information, including labels, instructions and other identification contents and product qualification certificates, so as to ensure that there is enough information to evaluate the safety of food contact materials and products. The contents of the logo shall include the product name, materials, statement of compliance with relevant laws and standards, name, address and contact information of the manufacturer and/or distributor, production date and shelf life (if applicable), etc.

The end products of food contact materials and products shall be marked with "food contact" and "food packaging" or similar terms, or printed with chopsticks. The identification content should first appear on the product or product label, and the label should be located in the eye-catching position of the minimum sales package of the product.

The extended information is a triangle composed of three arrows, with 5 written on it and P.P written below. This sign shows that the box is made of PP, that is, polypropylene plastic, which is safer.

For microwave special glass bowls with covers and ceramic bowls with covers, the cover must also be marked with the logo of polypropylene material PP. Pay attention to the air permeability of the lunch box when using it, and you need to open the small hole on the cover to use the microwave oven. Most ceramic bowls can be used for microwave, and glass bowls should be made of heat-resistant glass. Ordinary glass bowls are not heat-resistant.
