? Here's a "secret at the bottom of a beverage bottle" that I hope can help you:
All mineral water bottles have a triangle with an arrow at the bottom. There is a number in the triangle:
General mineral water bottle, bottom marked 1
Nongfu Spring is 4 liters, and the bottom is marked with 2.
Plastic heat-resistant cup for making tea, marked with 5 at the bottom.
Now analyze the following pictures for everyone:
★PET polyethylene terephthalate
Common mineral water bottles, carbonated beverage bottles, etc. Heat resistance to 70℃ is easy to deform, and substances harmful to human body are melted out. 1 Plastic product may release the carcinogen DEHP after using 10 months. Can't put it in the car to bask in the sun; Don't pack alcohol, oil and other substances!
★HDPE high density polyethylene
Common white medicine bottles, cleaning products, bath products. Don't use it as a drinking cup, or as a storage container to hold other items. If the cleaning is not thorough, do not recycle it.
★ PVC
Common raincoats, building materials, plastic films, plastic boxes, etc. Excellent plasticity, low price, so it is widely used, and can only resist heat of 8 1℃. It is easy to produce bad substances at high temperature, and is rarely used in food packaging. It is difficult to clean and easy to remain, so don't recycle it. Don't buy drinks if they are packed.
★PE polyethylene
Common cling film, plastic film, etc. Harmful substances are produced at high temperature, and toxic substances may cause diseases such as breast cancer and neonatal birth defects after entering the human body with food. Don't put plastic wrap in the microwave.
★PP polypropylene
Common soybean milk bottles, yogurt bottles, fruit juice bottles, microwave lunch boxes. With a melting point as high as 167℃, it is the only plastic box that can be put into a microwave oven and can be reused after careful cleaning. It should be noted that some microwave lunch boxes are made of No.5 PP, but the lid is made ofNo. 1 PE. Because PE can't withstand high temperature, it can't be put into the microwave with the box.
★PC polystyrene
Common bowl-packed instant noodle boxes and fast food boxes. Can't put it in the microwave oven to avoid releasing chemicals due to excessive temperature. After being filled with acid (such as orange juice) and alkaline substances, carcinogens will be decomposed. Avoid packing hot food in fast food boxes. Don't cook bowls of instant noodles in the microwave oven.
★PC other classes
Common kettles, space cups and milk bottles. Department stores often use water cups made of this material as gifts. It is easy to release the toxic substance bisphenol A, which is harmful to human body. Don't heat it when using it, and don't directly bask in the sun.
