Its high temperature resistance is slightly inferior to PP plastic bags, but it can be directly placed in the refrigerator without worrying about breakage.
2. PP plastic bags are the most common, with the property of high temperature resistance but not low temperature resistance. PP plastic bags can still maintain their shape when exposed to high temperature food, so avoid putting them in the refrigerator.
