There is a triangle at the bottom of the mineral water bottle. What does the word “1” mean!?

by admin

there is a triangle at the bottom of the mineral water bottle, in which a 1 represents PET material, and the number in the triangle mark is the recycling mark of plastic products. Pet is polyethylene terephthalate, which is heat-resistant to 70 ℃ and easy to deform, and substances harmful to human body melt out. Common in mineral water bottles, carbonated beverage bottles, etc. It is easy to deform when the temperature reaches 70 ℃, and can not contain alcohol, oil and other substances at high temperature

therefore, pet water bottles can not be recycled to contain hot water. This material is heat-resistant to 70 ℃, and is only suitable for warm or frozen drinks. When containing high-temperature liquid or heating, it is easy to deform and dissolve substances harmful to human body. In addition, scientists found that after 10 months of use, this plastic product may release carcinogens and be toxic to human body. So throw away the drink bottles when they are used up. Don’t use them as water cups or storage containers to hold other items, so as not to cause health problems

extended data:

the material mark of plastic products required in the national standard recycling mark of plastic packaging products, which was implemented in China as early as 1996. The main purpose of this standard is to distinguish the materials of plastic products through different marks, so as to facilitate recycling. Polyester code 01 pet, high density polyethylene code 02 HDPE, polyvinyl chloride code 03 PVC, low density polyethylene 04 LDPE, polypropylene code 05 PP, polystyrene code 06 PS, other plastics code 07

represents No. 1 plastic, general mineral water bottle, marked with 1 at the bottom,
No. 1 plastic, scientific name pet polyethylene terephthalate
common mineral water bottle, carbonated beverage bottle, etc. Heat resistant to 70 ℃, easy to deform, and substances harmful to human body melt out. It is a strong carcinogen. No. 1 plastic may release carcinogen DEHP after 10 months of use. Do not put it in the sun in the car; Do not contain alcohol, oil and other substances. This kind of plastic is not very safe. It is said that someone has hung up a mineral water bottle for 18 months
in addition, there are 6 other total plastics, and No. 5 is the safest
No. 2: HDPE high density polyethylene
common white medicine bottles, cleaning products and bath products. Don’t use it as a water cup or as a storage container for other items. Do not recycle if the cleaning is not complete
No. 3: PVC PVC
common raincoats, building materials, plastic films, plastic boxes, etc. Excellent plasticity and low price, so it is widely used. It can only resist heat at 81 ℃ It is easy to produce bad substances at high temperature and is rarely used in food packaging. Difficult to clean, easy to residue, do not recycle. Don’t buy drinks
No. 4: PE polyethylene
common fresh-keeping film, plastic film, etc. When high temperature has harmful substances, toxic substances enter the body with food, which may cause breast cancer, neonatal congenital defects and other diseases. Don’t put plastic wrap in the microwave
No. 5: PP polypropylene
common soymilk bottles, yogurt bottles, fruit juice beverage bottles, microwave oven lunch boxes. Melting point up to 167 ℃, it is the only plastic box that can be put into the microwave oven and can be reused after careful cleaning. It should be noted that for some microwave oven lunch boxes, the box body is made of No. 5 PP, but the box cover is made of No. 1 PE. Because PE cannot withstand high temperature, it cannot be put into the microwave oven together with the box body
No. 6: PS polystyrene
common bowl instant noodle boxes and fast food boxes. Do not put it in the microwave oven to avoid releasing chemicals due to excessive temperature. After containing acid (such as orange juice) and alkaline substances, carcinogens will be decomposed. Avoid packing hot food in fast food boxes. Don’t cook a bowl of instant noodles in the microwave
No. 7: other types of PC
common kettle, space cup and milk bottle. Department stores often use water cups made of this material as gifts. It is easy to release toxic substance bisphenol A, which is harmful to human body. Do not heat when using, do not directly sun in the sun
some materials refer to Encyclopedia

(it is a triangle with an arrow, and there is a number in the triangle). If the number is “05” or above, it can be recycled. The larger the number, the safer it is. If it is less than “05”, i.e. “04” or below, or even no number, please do not reuse or heat it. * Generally, the bottom of mineral water bottle is marked with 1 (so don’t put it in the sun in the car!!) * The bottom of the plastic heat-resistant bowl at the noodle stall is marked with 5 * the bottom of the plastic heat-resistant cup for making tea is marked with 5 * the bottom of the Nestle milk essence bottle is marked with 2 * the bottom of the yogurt bottle advertised by Lin Zhiling is marked with 2 plastic material number polyethylene terephthalate (PET), commonly known as Baote bottle. High density polyethylene (HDPE, PE) polyvinyl chloride (PVC) low density polyethylene (LDPE, PE) polypropylene (PP) polystyrene (PS). If expanded polystyrene is used, it is commonly known as “Baolilong”

“1” stands for pet (polyethylene terephthalate)
this material is used in general mineral water, carbonated beverage and functional beverage bottles. It is heat-resistant to 70 ℃ and easy to deform. Repeated use for a long time may release harmful substances. In hot weather, try not to store mineral water in the open air or in the car for a long time, and do not directly flush boiled water into the mineral water bottle

reference: tieba/P /782381182
so don’t always drink mineral water
I wish you good health

this doesn’t seem to make much sense. Maybe it just means a sealing plate in different areas of the bottle bottom
such as A1, 10, 1 Pet and O (similar)
