Why PET-type plastic beverage bottles can't hold hot water?

Beverage bottles do not recycle with hot water

  Use: heat-resistant to 70 degrees C, only suitable for warm drinks or frozen drinks, high temperature liquid, or heating is easy to deform, there is harmful substances to the human body meltout. And, scientists have found that PET plastics may release the carcinogen DEHP after 10 months of use, which is toxic to the testicles.

Therefore, the beverage bottle and so on when used away, do not use as a water cup, or used as a storage container to multiply other items, so as not to cause health problems.

The plastic box has a little health certificate.

  Would you use a used drink bottle as a water cup? Do you know which plastic containers release toxic carcinogens by placing hot water? In fact, each plastic container has a small ID card - a triangular symbol, usually at the bottom of the plastic container. The triangle has 1 to 7 numbers, each number represents a plastic container, their production material is different, the use of taboo also different.

"Number 1" PET: mineral water bottle, carbonated beverage bottle

  Beverage bottles do not recycle with hot water

  Use: heat-resistant to 70 degrees C, only suitable for warm drinks or frozen drinks, high temperature liquid, or heating is easy to deform, there is harmful substances to the human body meltout. And, scientists have found that plastic No. 1 may release the carcinogen DEHP after 10 months of use, which is toxic to the testicles.

Therefore, the beverage bottle and so on when used away, do not use as a water cup, or used as a storage container to multiply other items, so as not to cause health problems.

  "Number 2" HDPE: cleaning supplies, bath products

  Cleaning is not thoroughly recommended do not recycle

  Use: Can be carefully cleaned after reuse, but these containers are usually not easy to clean, residual original cleaning supplies, into a hotbed of bacteria, you should not recycle.

"Number 3" PVC: rarely used in food packaging at present

  It's best not to buy

  Use: This material high temperature is easy to have harmful substances, even in the manufacturing process it will be released, toxic substances with food into the human body, may cause breast cancer, newborn birth defects and other diseases. At present, the container of this material has been used less for packaging food. If you are using it, do not let it get heated.

"Number 4" LDPE: preservation film, plastic film, etc.

  The cling film is not wrapped in the microwave oven on the surface of the food

  Use: heat resistance is not strong, usually, qualified PE cling film in the temperature of more than 110 degrees C when the phenomenon of hot melt, will leave some human body can not decompose plastic preparations. In addition, with cling film wrapped in food heating, food fat can easily dissolve the harmful substances in the cling film. Therefore, the food into the microwave oven, first to remove the wrapped film.

"Number 5" PP: Microwave lunch box

  When you put it in the microwave, remove the lid.

  Use: The only plastic box that can be put into the microwave oven can be reused after careful cleaning. It is important to note that some microwave oven lunch boxes, box body is indeed made with no. 5 PP, but the lid is made with no. 1 PE, because PE can not withstand the high temperature, it can not be put into the microwave oven with the box body. To be safe, remove the lid before placing it in the microwave oven.

"Number 6" PS: Bowl bubble noodle box, fast food box

  Don't cook bowls of instant noodles in the microwave.

  Use: heat and cold resistance, but can not be put into the microwave oven, so as not to release chemicals due to excessive temperature. And can not be used to multiply strong acid (such as orange juice), strong alkaline substances, because it will break down the human body is not good polystyrene, easy to cause cancer. Therefore, you should try to avoid packing hot food in a fast food box.

"Number 7" PC other categories: kettles, water glasses, bottles

  PC glue in pyrolysis BPA

  Use: A material that is heavily used, especially in bottles, and is controversial because it contains BPA. In theory, as long as BPA is converted into a plastic structure in the process of making a PC, it means that the product is completely free of BPA, let alone released, said Lin Hanhua, an associate professor in the Department of Biology and Chemistry at the City University of Hong Kong. However, if a small amount of BPA is not converted into a PLASTIC structure of a PC, it may be released into food or drink. Therefore, be careful, take extra care when using this plastic container.
