When we buy a paper lunch box, we find a few numbers at the bottom. What do they mean? What's the use? The triangular logo at the bottom of the paper meal box corresponds to the product logo. At present, the main packaging boxes on the market are no. 1, no. 5 and No. 6, which are generally safe.
No. 1 and no. 6: Poor heat resistance, can not be heated, can not hold high temperature food. The plastic bottles of mineral water, fruit juice and carbonated drinks all use no. 1 material; Now many milk tea LIDS are no. 6.
No. 5: It can withstand high temperatures of around 200 degrees C. It can be heated in the microwave and reheated over and over again with no problem. Microwaves can only heat plastic no. 5. When choosing a plastic product, people can put it in the microwave as long as they see five marks on the bottom triangle. At present, most disposable plastic tableware used in the market is made of PP (polypropylene) material, which has high safety and good thermal stability. Heat resisting temperature up to 130℃.
