Chinese standard for food glassware

Chinese standard for food glassware：
Food glassware, including glasses, needs to be subject to more stringent standards to ensure food safety.
In China, the standards for food contact materials mainly refer to the following two :1. GB 4806.5-2016 "National Standard for Food Safety Glass Products" : this is the national standard for food contact glass products, which specifies the dissolution limit of harmful substances such as lead and cadmium in glass products, as well as the requirements for physical properties Q and chemical properties.
This standard applies to all glass products that come into direct contact with food, including glasses.
2. QB/T 4162-2021 "Glassware Glasses" : Although this standard is mainly for glasses, it also includes requirements for glasses applicable to food contact, such as material selection, manufacturing process, heat resistance, etc.
These standards ensure that food glassware does not release harmful substances under normal conditions of use, thus protecting the health of consumers.
Specifically, the GB 4806.5-2016 standard contains the following points: The dissolution limit of harmful substances: specifies the dissolution limit of heavy metals such as lead and cadmium to ensure that these substances do not cause harm to human health.
Physical performance requirements: including glass heat resistance, cold resistance, impact resistance, etc.
Chemical performance requirements: Ensure that glassware will not undergo chemical reactions and release harmful substances when it comes into contact with food.
Therefore, for glasses used in food, manufacturers need to ensure that their products meet the above standards, and consumers can also check whether the product is marked with these standards at the time of purchase.
