It is the safest to use it correctly according to the requirements.

No. 1 PET polyethylene terephthalate

Common mineral water bottles, carbonated beverage bottles, etc. Heat-resistant to 70°C, it is easy to deform, and some harmful substances are melted out. No. 1 plastic product may release carcinogen DEHP after 10 months of use. Don't put it in the car to bask in the sun; don't put alcohol, oil and other substances.

No. 2 HDPE high density polyethylene

Common white medicine bottles, cleaning supplies, and bath products. Don't use it as a water cup or as a storage container for other items. If the cleaning is not thorough, do not recycle.

No. 3 PVC polyvinyl chloride

Common raincoats, building materials, plastic films, plastic boxes, etc. It has excellent plasticity and low price, so it is widely used and can only heat up to 81℃. It is easy to produce bad substances at high temperature and is rarely used for food packaging. Difficult to clean and easy to remain, do not recycle. Do not purchase if it contains drinks.

No. 4 PE polyethylene

Common cling film, plastic film, etc. Harmful substances are produced at high temperatures, and toxic substances enter the human body with food, which may cause diseases such as breast cancer and birth defects of newborns. Do not put the plastic wrap into the microwave oven.

No. 5 PP polypropylene

Common soy milk bottles, yogurt bottles, juice drink bottles, microwave lunch boxes. With a melting point of 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 in some microwave oven lunch boxes, the box body is made of No. 5 PP, but the lid is made of No. 1 PE. Because PE cannot withstand high temperatures, it cannot be placed in the microwave together with the box. Pay special attention to transparent PP, which is not microwave oven PP, so products made by it cannot be placed directly in the microwave oven.
