Identification of Biodegradable Cutlery

At first glance, we must first see whether there is a QS logo and number on the lunch box; secondly, we must also see whether the surface of the lunch box is smooth, with impurities or black spots. Generally speaking, transparent plastic lunch boxes are made of pure polypropylene (PP), which has a relatively high safety factor; brightly colored lunch boxes may use waste plastic, so the darker the color, the more unsafe. The second touch is to feel the strength of the lunch box. The lunch boxes made with recycled waste or a large amount of industrial-grade calcium carbonate and talcum powder are generally poor in strength, and they will break with a slight tear. The third smell is to smell the peculiar smell of the lunch box, and the qualified lunch box cannot smell the smell.
