Why can t you use a plastic container for hot water?

Because it is easy for plastic utensils to dissolve the plasticizers in the water due to heat when filling hot water, which affects our health, so do not use plastic utensils to fill hot water.

Because the substance of plastic utensils is not very stable, it will release some toxins when it is filled with hot water, and there will be problems when it is used, which may lead to carcinogenic substances.

Plastic utensils will be deformed at high temperatures, and harmful substances will be produced, which can cause cancer when ingested into the human body, so plastic cups are generally not used to fill hot water, but paper cups are used for hot water, and plastic cups are used for drinks.

The cups of this material can be filled with hot boiled water and can also be recycled. But before filling it with boiling water, it is best to use boiling water to shabu a cup.

The plastics usually used to make water cups are PE, PP, PC, PET and other materials.

Generally, there will be a triangle at the bottom of the plastic product.

symbol, this triangle symbol is a plastic ** sign.

The numbers range from 1 to 7, and each number represents a different raw material for making plastics, so it is also different in use.

No. 1 is PET, No. 2 is HDPE, No. 3 is PVC, No. 4 is LDPE, No. 5 is PP, No. 6 is PS, No. 7 is PC and other materials. The commonly used disposable water cup is PE, which is soft, not resistant to high temperature, and will become soft when filled with boiling water, and long-term boiling water may cause plastic decomposition and produce substances harmful to human health.

A cup that is more suitable for daily drinking water:

Glasses, enamel cups, ceramic cups, plastic cups, stainless steel cups, iron cups, aluminum cups, paper cups, ......When we go to the mall to buy water cups, all kinds of cups will break into our sight, especially those cups with bright colors and unique shapes are eye-catching.

Glasses should be preferred when drinking water:

Don't think that glasses are just transparent and beautiful, among all the materials, glasses are the healthiest. Glasses do not contain organic chemicals, so when people drink water or other beverages from a glass, they don't have to worry about chemicals being drunk into their stomachs, and the glass surface is smooth and easy to clean, so people drink water from a glass is the healthiest and safest.

The plastic cup made of PP material can be filled with hot water.

Polypropylene (PP) is the only material that can be heated in the microwave.

The triangular symbol engraved on the bottom of the plastic container can tell if they are safe or not.

05" stands for PP (polypropylene).

01": Throw it away after drinking.

"01" stands for PET (polyethylene terephthalate), which is most commonly used in making bottled beverages such as mineral water and carbonated drinks. It cannot be filled with hot water, only suitable for warm or frozen drinks.

02": It is not recommended to be used as a water container.

"02" stands for HDPE (high-density polyethylene), which is used to hold plastic containers for cleaning products and bath products, and most of the plastic bags commonly used in shopping malls are made of this material.

03": Never let it get heated.

"03" stands for PVC (polyvinyl chloride), which is commonly found in raincoats and plastic films. It is rarely used in food packaging and should never be exposed to heat.

04": More than 110 will melt.

04" stands for LDPE (low-density polyethylene), a raw material for plastic wrap and plastic film, and it is not very heat-resistant.

05": Reuse after careful cleaning.

"05" stands for PP (polypropylene), which is the only material that can be heated in a microwave oven, so it is used as a raw material for making microwave lunch boxes, and it can be reused after careful cleaning.

The bottom of the plastic cup is No. 05, indicating that the water cup is made of polypropylene material, which can withstand high temperatures of up to 167 and is the only plastic box that can be put in the microwave oven and can be reused after cleaning.

The water cup made of PC will release the toxic substance bisphenol A at high temperatures, which is harmful to the human body. In addition, the bottom of the No. 05 cup is also marked with the word PP, indicating that the cup can also be used for consumption.

Therefore, a plastic cup with a bottom of No. 05 or the word PP can be filled with hot water.

Each variety of plastic cups has a variety of numbers and environmental protection marks on the bottom, selected according to the remarks. There are a few of them:

The PP plastic cup is non-toxic and tasteless, and its maximum temperature is 167 degrees, which means that there is no problem at all with boiling water.

02" stands for HDPE (High Density Polyethylene), which can withstand high temperatures of 110.

05" heat-resistant 130 and "05" stands for PP (polypropylene), which is the only material that can be heated in a microwave oven, so it is used as a raw material for making microwave lunch boxes. It is resistant to high temperatures of 130 and has a melting point of up to 167

07" Heat resistance: 120, "07" stands for PC and other types of PC, which is a material that is widely used, mostly used in the manufacture of baby bottles, space cups, etc., because it contains toxic bisphenol A and is controversial. Do not heat or expose to direct sunlight and avoid reusing aged plastic cups.

The above are plastic cups that can be used.

Plastic bottles cannot be filled with hot water.

The common plastic bottles of mineral water, fruit juice and carbonated drinks are No. 1 plastic products, made of polyethylene terephthalate (PET), which are heat-resistant to 70 degrees Celsius and deformed, and harmful substances begin to dissolve; It is a single-use container and cannot be reused. The plastic bottle has an "ID card", with a triangle symbol at the bottom + a number (1-7) in the middle, and the small triangle is the ** sign.

The number is any of 1 and 7, and each represents a plastic material. No. 1 plastic products are heat-resistant to 70, and are easy to deform when filled with high-temperature liquid or heated, and there are harmful substances to the human body to melt. Recommendations:

Throw away the bottle after drinking it, and do not use it as a water cup or storage container to avoid health hazards.

Plastic bottles

Plastic bottles are mainly made of materials such as polyethylene or polypropylene and added with a variety of organic solvents. Polyester (PET), polyethylene (PE), and polypropylene (PP) are widely used as raw materials for plastic bottles, and the corresponding organic solvents are added, heated at high temperatures, and then blown by plastic molds, extruded, or injection molded plastic containers.

It is mainly used for liquid or solid disposable plastic packaging containers such as beverages, food, pickles, honey, dried fruits, edible oils, pesticides and veterinary drugs. Plastic bottles have the characteristics of not easy to break, low cost, high transparency, and food-grade raw materials.

No. PC cups can not be filled with hot water, PC materials are polycarbonate, commonly used in kettles, space cups, baby bottles, department stores often use such material cups as gifts.

However, the cup of this material is generally not resistant to high temperature, if it is heated or in an acidic and alkaline environment, it is easy to release the toxic substance bisphenol A (BPA), so do not use it to hold hot water, and it is best to use warm water for cleaning.

The dangers of plastic cups.

Fewer and fewer people drink from plastic cups, because plastics are often added with plasticizers, which contain some toxic chemicals. When using plastic cups for hot water, toxic chemicals are easily diluted into the water, and the internal microstructure of the plastic has many pores.

There is dirt hidden in it, and it is easy for bacteria to grow if it is not cleaned cleanly. Therefore, when buying plastic cups, you must choose a water cup made of food-grade plastic that meets national standards.
