Food-grade PP material has relatively good chemical stability, hardly absorbs water, and will not interact with most chemicals, so it is suitable as a raw material for food-grade tableware and is widely used in daily life. If you choose industrial-grade PP material, after high temperature, harmful and toxic chemical components may be produced, which will be harmful to the human body after long-term use.
Food-grade PP materials are generally not harmful to the human body. Tableware made of food-grade PP materials usually have better heat resistance. After high-temperature cooking, no harmful and toxic substances will be produced, so they are relatively safe.
Food-grade PP refers to the plastic material that can be in direct contact with food. It is non-toxic and cannot be eaten directly. If ordinary PP plastic products cannot be in direct contact with food, it will indirectly affect food safety. Food-grade PP can In direct contact with food.
The difference between food grade and industrial grade is:
Food-grade PP will not dissolve harmful substances under normal conditions and high temperature conditions.
Industrial-grade PP will dissolve harmful substances at room temperature or high temperature, which will cause harm to human health. When some are used in food containers, they will have a strong odor when heated.
