The first one is check the bottom of the bottle, which usually has numbers. The number 1 represents PET, that is polyethylene terephthalate. The second is through the appearance of the bottle, high transparency, crush resistance, generally such a bottle can be basically determined as a PET bottle.
Because of PET bottles' excellent performance and are easy to cleane after use, many people have a habit of cleaning PET bottles before use. So, what should you pay attention to when recycling PET bottles? Can PET bottles be filled with hot water? First of all, PET bottles can only withstand temperatures up to 70 degrees. When the temperature exceeds 70 degrees, the stability of PET will be affected and harmful substances will be released. Therefore, hot water of more than 70 degrees should not be packed in PET bottles for health and safety considerations. Secondly, PET bottles and all plastics products should not be used repeatedly for a long time. Finally, thers is no problem to use PET bottle occasionally to hold warm water, which also serves as a waste recycling.
