What does it mean to have China under the bottom of a plastic bottle

Billion Saint Nylon reminds you! This may be the origin of the plastic material of this bottle in China!

Common bottle bottom ** distinguishing method:

At the bottom of each plastic water bottle is a triangle with an arrow, and the triangle has a number inside.

Inside the triangle is PET polyethylene terephthalate.

Common mineral water bottles, carbonated drink bottles, etc. Heat-resistant to 70 easy to deform, there are harmful substances to the human body melting. After 10 months of use, the No. 1 plastic product may release the carcinogen DEHP. It cannot be left in the car in the sun; Do not fill it with alcohol, oil, etc.

Inside the triangle is HDPE high-density polyethylene.

Common white medicine bottles, cleaning products, bath products. Do not use it as a drinking glass or as a storage container for other items. Do not recycle if you do not clean thoroughly.

Inside the triangle is PVC polyvinyl chloride.

Common raincoats, building materials, plastic films, plastic boxes, etc. The plasticity is excellent and the price is cheap, so it is very common to use, and it can only withstand heat 81At high temperatures, it is easy to produce undesirable substances, and it is rarely used in food packaging.

It is difficult to clean and easy to remain, so do not recycle. Do not buy drinks if they are contained.

Inside the triangle is PE polyethylene.

Common plastic wrap, plastic film, etc. Harmful substances are produced at high temperatures, and after toxic substances enter the human body with food, they may cause diseases such as breast cancer and birth defects in newborns. Keep plastic wrap out of the microwave.

Inside the triangle is PP polypropylene.

Common soy milk bottles, yogurt bottles, juice drink bottles, and microwave lunch boxes. With a high melting point of 167, it is the only plastic case that can be put in the microwave oven and can be reused after careful cleaning. It should be noted that some microwave oven lunch boxes are made of No. 5 PP, but the lid is made of No. 1 PE, because PE cannot withstand high temperatures, so it cannot be put into the microwave oven with the box.

Inside the triangle is ps polystyrene.

Common bowls of instant noodle boxes, fast food boxes. Do not put it in the microwave oven to avoid releasing chemicals due to excessive temperature. When it is filled with acids (such as orange juice) and alkaline substances, carcinogens are decomposed. Avoid packing piping hot food in fast food boxes. Don't microwave instant noodles in a bowl.

Inside the triangle are the pc other classes.

Common water bottles, space cups, baby 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 the human body. Do not heat when using and do not expose to direct sunlight.

There are numbers at the bottom of the plastic bottle, from 1 to 10 or so, different numbers represent different materials (you can find out what material is on the Internet), it can also be said to be the safety level or safety factor, the larger the number, the higher the safety level, of which only more than 5 bottles can be reused, that is to say, 5 or less can not be reused, and our common bottles are 1, if reused, it will generally cause cancer in about half a year, There have been many undeserved tragedies with friends who don't understand.

As for glass bottles and ceramic bottles, they are generally relatively safe and healthy, and their quality distinction is not very well understood......

It can be acquired, but it is now stipulated that it must be dealt with locally first. And you have to have the right to import.

It's a recycling sign, a number in the logo.

1"—PET (polyethylene terephthalate).

Mineral water bottles and carbonated drink bottles are made of this genus material. This material is heat-resistant to 70 degrees, and it is easy to deform when it is filled with high-temperature liquid or heated, and harmful substances will be dissolved. At the same time, after 10 months of use, this plastic product may release carcinogens.

2"—HDPE (High Density Polyethylene).

Most of the plastic containers containing cleaning products and bath products are made of this material, which can withstand 110 degrees of high temperature. However, these containers are often difficult to clean and can easily become a breeding ground for bacteria, so it is best not to recycle.

4"—LDPE (Low Density Polyethylene).

Plastic wrap, plastic film, etc. are all made of this material. The heat resistance is not strong, and the food should be removed from the wrapped plastic wrap first when entering the microwave oven.

5"—PP (polypropylene).

It is mostly used in the manufacture of microwave oven lunch boxes. It is resistant to 130 degrees of heat and is the only plastic case that can be put in the microwave. It is important to note that the lid of some lunch boxes is not resistant to high temperatures, and it is best to remove the lid before heating.

6"—ps (polystyrene).

It is mostly used to make bowls of instant noodle boxes and foamed fast food boxes. It is resistant to heat and cold, but it should not be put in the microwave, and try to avoid using it to pack hot food.

7"—PC (polycarbonate) and others.

PC is mostly used in the manufacture of baby bottles, space cups, etc., and is controversial because it contains bisphenol A. Experts point out that extra care should be taken when using this plastic container.

1: Stands for PET (polyethylene terephthalate): It is used in general mineral water, carbonated drinks and energy drink bottles.

It is resistant to 70 degrees and is easy to deform, so do not put it in the open air or in the car in hot weather, and do not flush boiling water directly into it. Long-term cycling is not recommended as carcinogens may be released after 10 months of use.

2: HDPE (high-density polyethylene): mostly used in the manufacture of containers for cleaning products. It is resistant to high temperatures but not easy to clean, easy to breed bacteria, and is not recommended for recycling.

3: On behalf of PVC (polyvinyl chloride): the toxic and harmful substances that are easy to produce come from two aspects, one is the single-molecule vinyl chloride that is not completely polymerized in the production process, and the other is the harmful substances in the plasticizer.

These two substances are easily released when exposed to high temperatures and oils, and toxic substances can easily cause cancer when they enter the human body with food.

4: On behalf of LDPE (low-density polyethylene): plastic wrap, plastic film and other materials are mostly used in this material, heat resistance is not strong, it will melt when the temperature exceeds 110, remember to remove it before heating it in the microwave.

5: Representative PP (polypropylene): The microwave oven lunch box is made of this material, which is resistant to 130 high temperatures, and is the only plastic box that can be put into the microwave oven, and can be reused after cleaning.

However, some lunch boxes are made of No. 5 PP with a body and a No. 6 PS (polystyrene) lid, so the lid cannot be put in the microwave.

6: On behalf of PS (polystyrene): mostly used in the manufacture of bowls of instant noodle boxes, foaming fast food boxes of materials, can not be put into the microwave oven, can not be used to contain strong acids (such as orange juice), strong alkaline substances, because it will decompose harmful to the human body polystyrene and other carcinogens.

So don't use a fast food box to pack food with high temperatures.

7: On behalf of other categories: mostly used to make baby bottles, space cups, etc. However, because it contains bisphenol A, try not to use it in boiling water.

58 refers to.

The material is made of PC, i.e. polycarbonate bottles, and the recently controversial BPA-containing bottles refer to PC bottles. This material can reach more than 100 degrees in temperature resistance, but due to the limitations of the current production process, the monomer can not be completely polymerized, so a small amount of bisphenol A will remain, and these bisphenol A will be precipitated at high temperatures, which has an impact on the physical development of infants, so now the European Union also prohibits the use of PC as feeding bottles. But it's perfectly fine with cold water!

Most of those bottled water bottles are PC bottles now.

What you see should be a triangle with 58 inside, and at the same time 58 is written below, the product may contain bisphenol A 58 is the new code name corresponding to the PC material.

1——PET polyethylene terephthalate is commonly found in mineral water bottles, carbonated beverage bottles, etc. When the temperature reaches 70, it is easy to deform, and there are substances harmful to the human body to melt. After 10 months of use, No. 1 plastic may release the carcinogen DEHP.

This type of bottle cannot be placed in the car to bask in the sun, and cannot contain alcohol, oil and other substances.

Polyethylene terephthalate The chemical formula is -[OCH2-CH2OCoC6H4CO]- English name: Polyethylene Terephthalate, referred to as PET, is a high polymer, which is derived from the dehydration and condensation reaction of ethylene terephthalate. Ethylene terephthalate is obtained by esterification of terephthalic acid and ethylene glycol.

PET is a milky white or light yellow, highly crystalline polymer with a smooth and shiny surface. It has excellent physical and mechanical properties in a wide range of temperatures, with a long-term use temperature of up to 120, excellent electrical insulation, and even at high temperature and high frequency, its electrical properties are still good, but the corona resistance is poor, creep resistance, fatigue resistance, friction resistance, and dimensional stability are very good.

Advantages of PET as packaging material: It has good mechanical properties, the impact strength is 3 5 times that of other films, and the folding resistance is good. Resistant to oils, fats, dilute acids, dilute alkalis, and most solvents.

It has excellent high and low temperature resistance, can be used for a long time in the temperature range of 120, can withstand 150 high temperature in short-term use, can withstand -70 low temperature, and has little impact on its mechanical properties at high and low temperatures. Low gas and water vapor permeability, excellent gas blocking, water, oil and odor properties. High transparency, can block ultraviolet rays, good gloss.

It is non-toxic, tasteless, hygienic and safe, and can be directly used in food packaging.

Why is the safe use period of PET1 10 months and the shelf life of mineral water 12 months?

Polyester plastic can resist acid and alkali corrosion, but it is not resistant to high temperatures, and the temperature above 60 degrees will produce harmful substances. It is suitable for disposable food packaging containers.

Tell you that the material of this bottle is PET, and this material can only be used once. Repeated use will cause dehp precipitation, which is harmful to the human body.

Different numbers tell us about the chemicals that make the beverage bottles.

It is PET bottle-grade polyester chips. I have this product for sale here.

The number inside the triangle at the bottom of the plastic bottle? It turns out that there are still these meanings!

China's English is China, meaning ** in ancient times, China's porcelain industry is relatively developed, and later exported to foreign countries, foreign countries gave porcelain an English name called China, over time, evolved into a general term for China.

In 2006, according to the estimation of relevant experts, the first rate of scrap aluminum cans in China is about 85%, and China produces at least 160,000 tons of cans every year, plus a small amount of imported canned drinks, with a total amount of about 200,000 tons.

In 2006, China's cans reached 8.5 billion, this year about 10 billion, by 2010 the output of carbonated drinks will reach 8 million tons, if the canning rate is calculated according to 20, the amount of cans will reach 12.4 billion.

According to data from China's environmental protection network, Chinese drink 100 bottles of 227ml bottled water a year, and according to incomplete statistics, China produces 3.5 million tons of waste plastic bottles every year

Let's get a little more points, this is a lot of trouble.
