Food-grade plastic cans are generally made of high density polyethylene (HDPE). HDPE is a kind of acid and alkali resistant and stable material, which will not react with food chemically, and has good toughness, cold resistance and high temperature resistance. In addition, it is non-toxic and tasteless, and can be safely used for food packaging.

It is worth noting that although HDPE plastic barrels can be used for food packaging, not all HDPE plastic barrels can be used for food packaging. When buying food-grade plastic buckets, it is recommended to choose products that meet the national standards, so as to avoid putting food with too high oil temperature directly into the plastic buckets, so as not to damage the materials of the buckets.
