In summer, the use of crisper boxes is high. As awareness of food safety continues to increase, in addition to focusing on price, style and size, material and heat resistance have become important factors in purchasing a crisper. It is understood that the materials of the fresh-keeping boxes on the market are mainly plastic and glass. How have the two markets performed recently?
Some plastic crisper boxes are mainly made of PP or PE material. If the temperature exceeds its thermal limit, there is a danger of releasing the plasticizer. But it can't be said that plastic 'gets into the stove' will definitely pose a food safety hazard. Generally speaking, there are seven plastic types of identification codes for plastic products, such as "1 plastic for mineral water bottles; No. 2 plastic for food packaging bags, etc." No. 5 plastic is mainly composed of polypropylene, and the heat-resistant temperature can be It reaches 130°C, which is the only temperature that can be heated into a microwave. "Customers can check plastic storage boxes for the triangular "5" mark on the bottom to determine if they are "qualified" to "enter the furnace." brand, please avoid heating plastic lunch boxes for long periods of time while in use. "
At the same time, just because glass gets into the microwave doesn't mean it's foolproof. If you don't pay attention to the nuances of different glass materials and blindly put them in the microwave, there will be no small safety hazard.
"The glassware used in our daily life is made of ordinary glass, tempered glass and heat-resistant glass. Ordinary glassware can only be used as ordinary containers. Tempered glass is mainly used as building materials and home decoration, which requires high temperature. . Heat-resistant glass must be used." According to the staff of Qingdao Consumer Protection Committee, some glass fresh-keeping boxes appearing on the market now have the words "tempered heat-resistant glass" and "heat-resistant tempered glass", which sounds like heating and cooling. Fire is one thing, actually misleading consumers. "
The staff member said that according to the warning issued by the China Consumers Association, "tempered glassware has a high safety factor of spontaneous combustion risk of heat-resistant glassware", many consumers do not understand the difference between tempered glass and heat-resistant glass, and wrong tempered glass. The container was used for cooking, resulting in injuries after cracked tempered glassware. "
It is impossible for the average consumer to see the difference between "tempered" glass and "heat-resistant" glass from the outside, but there are still unclear signs in the market. At present, the China Daily Glass Enterprise Association has formulated relevant management measures, and the specific implementation work is being carried out one after another.
