How many plastics can be placed in the microwave for heating?
“No. 5” PP plastic can be placed in the microwave oven.
At the bottom of each plastic vessel there is a triangular and numeric logo with an arrow that must be clearly identified and used reasonably.
“No. 5” PP: PP is polypropylene. Common products include soy milk bottles, yogurt bottles, juice drinks bottles, and microwave lunch boxes. With a melting point of up to 167 ° C, it is the only plastic box that can be placed in a microwave oven and can be reused after careful cleaning. It should be noted that some microwave oven lunch boxes are made of No. 5 PP, but the cover is made of No. 1 PE, so it cannot be placed in the microwave oven together with the box.
