What kind of fast food box can go into the microwave oven? It is common to eat out and not finish or order too much. It's a pity to waste food. If you can't finish a meal, you can pack it and go. In the era of national takeout, fast food boxes that are in close contact with food are also indispensable.
Let's start with the more common plastic packaging boxes on the market. Take a closer look at the plastic lunch box. On the lid or bottom of the box, you will find a number mark. In fact, this is an international plastic classification. Different number marks indicate plastics of different materials. The common fast food boxes on the market mainly use 3 kinds of materials, namely No. 1, No. 5 and No. 6:
No. 1 polyethylene terephthalate (PET): plastic bottles of mineral water, fruit juice, carbonated drinks are made of it;
No. 5 polypropylene (PP): the best heat resistance, it is commonly used in plastic appliances that can be heated in microwave ovens;
No. 6 polystyrene (PS): Now many milk tea cups use it.
It is generally safe to pack food in plastic snack boxes of these materials.
