PP material itself is non-toxic. The products directly blown by it are nontoxic. However, its injection, extrusion and molded plastic products, such as pots, boxes and frames, contain a large amount of filler, pigment, plasticizer, anti-aging agent and so on. Therefore, some declared PP products are poisonous. But we usually use regular tableware products, there are national inspection standards, so it is non-toxic. So try to buy regular products.
