When we were a child and using a mineral water bottle, did the adults in our family ever tell us that you could not hold hot water in a mineral water bottle? Maybe you did not listen to your parents or filled the hot water, and then you found that the mineral water bottle was deformed and gave out a bad smell. Since then, you have never used a mineral water bottle.
Maybe we don't understand why can't water bottles with hot water, grow up slowly we know the material of water bottles is PET plastic, it will not only deform but also expel harmful substances from your body, However not all plastic cups can not hold hot water. So let's talk about which plastic cups can hold hot water and which can't.
Plastic cups that cannot hold hot water: PET( for mineral water bottles, soft drink bottles, HDPE( for bath products bottles), PVC( for decoration,) PC(for space cups).
Plastic cups for hot water: PP( for microwave lunchboxes ), is a microwave-ready plastic container that can be reused after careful cleaning, and is usually marked No. 5 on the bottle.
