Does using a water bottle in a plastic cup cause cancer?

No, the general cups are made of plastic, its plastic raw materials, and the cups are all food-grade raw materials, so there is no toxicity, unless you buy recycled materials (recycled materials), which will definitely be harmful to the body. When you buy it, you can also see it, first see if the outer packaging has safety testing, certificate, production date, manufacturer, etc., and then see if the cup has black spots, clean and bright generally there will be no problems, otherwise, even if it is made of recycled materials.

It depends on what kind of plastic, those that have a smell, or a plastic cup filled with hot water and boiling water has a smell, it will cause cancer, and the one without smell can be used, and the glass will not be!

You look at the small triangle on the cup, if it's a PP material, it's generally fine. However, it is recommended to drink water or use a porcelain cup.

The plastic used to hold food is polyethylene plastic, which is not toxic, and the toxic plastic is polyvinyl chloride plastic.

Plastic water cups are non-toxic at room temperature, and toxic substances will be produced if the temperature is too high. Plasticizers are often added to plastics, which contain some toxic chemicals, when hot water or boiling water is filled with plastic cups, toxic chemicals are easily diluted into the water, and the internal microstructure of plastics has many pores, which hide dirt, and it is easy to breed bacteria if it is not clean.

Plastic cups are harmful to hot water.

Plastic cups should not be filled with hot water. In addition to being heated, plastic cups are toxic except for the precipitation of some chemicals.

Plasticizers are often added to plastics, which contain some toxic chemicals, when hot water or boiling water is filled with plastic cups, toxic chemicals are easily diluted into the water, and the internal microstructure of plastics has many pores, which hide dirt, and it is easy to breed bacteria if it is not clean.

Molecular structure of plastics

There are basically two types: the first is the linear structure, and the polymer compound with this structure is called the linear polymer compound; The second type is the body structure, and the polymer compound with this structure is called the body type polymer compound.

Some polymers have branched chains, called branched polymers, which belong to the linear structure. Although some polymers have cross-links between molecules, there are fewer cross-links, which are called network structures, which belong to the body structure.

Two different structures that exhibit two opposing properties. Linear structure, heating can melt, less hardness and brittleness. The body structure is more rigid and brittle.

It depends on whether the material is resistant to high temperatures. For example, PP material is resistant to high temperatures. PS material is not resistant to high temperatures.

1. The PP plastic water cup is made of polypropylene, which has good thermal stability and insulation, safety and harmlessness to the human body. The product can be sterilized at a temperature of more than 100 meters, and under the condition of not being affected by external force, 150 meters will not be deformed, and there is no pressure in boiling water.

2. The PET material cup is heat-resistant to 70, and can be filled with room temperature water for a short time, and cannot be filled with acid-alkaline drinks or high-temperature liquids, nor should it be exposed to the sun, otherwise it will produce toxic substances harmful to the human body.

3. The plastic cup made of PS material is particularly brittle, low temperature resistance, and cannot be used in high temperature, strong acid, and strong alkali environment.

4. AS (acrylonitrile-styrene resin), PC material and other categories, used in pots, cups, feeding bottles, etc., with high safety and drop resistance, but not high temperature resistance. It is not harmful to drink cold water, but if it is filled with hot water, it will produce substances that are harmful to the human body.

Buy a plastic cup to look at the bottom of the bottle ** :(it's best not to buy the logo of 3, the best of the logo is 5).

1"——PET (polyethylene terephthalate), commonly found in mineral water bottles, carbonated beverage bottles, etc. When the temperature reaches 70 or more, it is easy to deform, and it is only suitable for warm or cold drinks. Generally, these bottles cannot be reused.

2" - HDPE (high-density polyethylene), not easy to clean, easy to breed bacteria, generally do not recycle.

3"——PVC (polyvinyl chloride), which is easy to produce carcinogens when exposed to high temperature and oil.

4" - LDPE (low density polyethylene), commonly found in plastic wrap, usually qualified plastic wrap will appear hot melt when the temperature exceeds 110. Many family leftovers after meals will be wrapped in plastic wrap, and some will be directly put into the microwave oven with plastic wrap when they are eaten next time, but this practice is actually unscientific.

5" – PP (polypropylene), the only microwave-safe plastic with a melting point of up to 167, can be reused after careful cleaning. Here is a reminder that there are some microwave oven lunch boxes on the market, its box body is indeed made of No. 5 plastic, but the box lid is the No. 1 plastic used, because the No. 1 plastic can not resist the high temperature, so the box lid can not be put into the microwave oven, for the sake of insurance, when heating with this kind of lunch box, it is best to remove the lid, or pay more attention when choosing.

6"-PS (polystyrene), commonly found in bowl-filled instant noodle boxes and fast food boxes, heat-resistant and cold-resistant, can not be used for microwaves.

7" - PC other types (polycarbonate, commonly found in kettles, space cups, feeding bottles, etc., but the cups of this material are easy to release toxic substances bisphenol A at high temperatures, which is harmful to the human body. Do not heat this cup when using it, and do not expose it to the sun.

Hope it helps.

There is a triangle under the cup, there are numbers in it, and the various numbers represent different uses, you can check the use of various numbers on the Internet, and then see if your cup is safe. I don't need plastic cups now, I can use porcelain.

The chemical composition of the glass is silica, of course, it will be fine, and the plastic cup depends on what it is, it is generally esters, but they contain a small amount of impurities, which contains harmful substances, but the probability of causing cancer is not too small, if you are not at ease, you can use a better space cup.

Regular products that meet the relevant standards are no problem.

It is better not to pour hot water on plastic cups.

Using a plastic cup is more or less harmful to the body, after all, it belongs to polymer and will not be beneficial to the body. However, drinking cold water or cold drinks will not be too harmful, if it is hot water or hot drinks, it will have a chemical reaction with the plastic cup, which may produce harmful substances to the human body, so try not to drink hot water with a plastic cup. The first choice for drinking water cups should be glasses, don't think that glasses are just transparent and good-looking, among all the materials of cups, glasses are the healthiest.

The glass does not contain organic chemicals in the firing process, when people drink water or other drinks with the glass, they do not have to worry about the chemicals being drunk into the stomach, and the glass surface is smooth, easy to clean, bacteria and dirt are not easy to breed on the wall of the glass, so people drink water from the glass is the healthiest and safest. The colorful ceramic cups are very pleasing, but in fact, there are huge hidden dangers in those bright pigments, especially the inner wall is coated with glaze, when the cup is filled with boiling water or acidic, alkaline drinks, the lead and other toxic heavy metal elements in these pigments are easy to dissolve in the liquid, and people drink the liquid with chemicals, which will cause harm to the human body. The plastic cup is often added with plasticizers, which contain some toxic chemicals, when the plastic cup is filled with hot water or boiling water, the toxic chemicals are easily diluted into the water, and the internal microstructure of the plastic has many pores, which hide dirt, and it is easy to breed bacteria if it is not clean.

Therefore, when we buy plastic cups, we must choose water cups made of food-grade plastics that meet national standards, and the first choice should be glasses.

Plasticizers are strictly defined in food packaging, do not cause harm to humans, and there is insufficient evidence of carcinogenicity.

Don't use a plastic cup to make tea, and if you drink boiling water, try using a glass.

Look at the number inside the triangle on the bottom of the bottle. Some are poisonous, some are non-toxic.

No. 1 "- PET

It is commonly found in mineral water bottles, carbonated drink bottles, etc. Heat-resistant to 70 easy to deform, only suitable for warm or cold drinks. If it is filled with high-temperature liquid, or when heated, it is easy to deform, and substances harmful to the human body are easy to melt out.

It is recommended that these bottles not be reused or used as storage containers for other items.

No. 2" - HDPE

It is commonly found in white medicine bottles, cleaning products, bath products, etc. It is recommended not to recycle, as these containers are often difficult to clean and can leave the original cleaning products behind and become a breeding ground for bacteria.

No. 3" - PVC

It is commonly found in raincoats, building materials, plastic films, plastic boxes, etc. It has excellent plasticity and low price, so it is very commonly used. However, it can only withstand heat 81, and it is easy to produce bad substances at high temperatures, so it is recommended not to recycle.

No. 4" – LDPE

Commonly found in plastic wrap. Normally, qualified PE plastic wrap will be hot melt when it encounters a temperature of more than 110. Therefore, it is advisable to remove the wrapping plastic wrap before putting food in the microwave.

No. 5 "- pp

It is commonly found in soy milk bottles, yogurt bottles, fruit juice drink bottles, microwave oven lunch boxes, etc. With a melting point of 167, it is a microwave-safe plastic that can be carefully cleaned and reused.

No. 6 "- ps

It is commonly found in bowl-filled instant noodle boxes and fast food boxes. Do not put it in the microwave oven to avoid releasing chemicals due to excessive temperature. After filling with acid and alkaline substances, it will decompose polystyrene, which is not good for the human body, so avoid packing hot food in fast food boxes, and do not use microwave ovens to cook instant noodles in bowls.

No. 7" - PC Miscellaneous Class.

It is commonly found in kettles, space cups, feeding bottles, etc. It is a material that is widely used, but it is controversial because it contains bisphenol A. Therefore, it is important to take extra care when using this plastic container.

If it is produced by a regular manufacturer and meets the quality standards, the cup is not toxic. The key is the quality of the cup

Don't ask about something so widely used as plastic cups.
