Information
  If you notice that plastic products often have a triangle with an arrow at the bottom,it is a"recycled"sign.At present,there are 140 kinds of plastic numbers in our country,and the code number of our common polycarbonate(PC)drinking water barrel is 58.The difference in Arabic numerals represents the different properties and uses of this plastic material,just like the identification of plastic products.Although the country and the industry have not made uniform requirements for the logo on the lunch box,listen to Professor Dong Jinshi's interpretation,and be ready to understand consumption.
  The number"1"means that the material of the plastic is PET,that is,polyethylene terephthalate,common mineral water bottles,carbonated beverage bottles,etc.,heat-resistant to 70℃,easy to deform,and dissolve out substances harmful to the human body;In the car in the sun,no alcohol,oil and other substances can be installed.Bottles with this logo can no longer be filled with water after being used.Bacteria and microorganisms have entered the bottle after opening,and the sanitation of the filled water cannot be guaranteed.In addition,plastics will age,and harmful substances may be precipitated after repeated use.Please throw them in a recyclable trash can and let it be recycled.
  The number"2"means that the plastic material is HDPE,which is commonly used as packaging bottles for cleaning products and shower products.It is often used in the production of food bags,and some beverage bottles are also made of this material.
  The number"3"represents that the material of the plastic is PVC.This kind of material is easy to produce harmful substances when it is high temperature,and it will even be released during the manufacturing process.After the toxic substances enter the human body with food,it may cause diseases such as breast cancer and birth defects of newborns.At present,this kind of material itself is very hard.To be easy to process,plasticizers are often added,especially PVC cling film.The content of plasticizer is more than 30%,and it cannot contain oily and high-temperature food.
  The number"4"represents that the material of the plastic is LDPE.General products are cling film,plastic film,etc.The heat resistance is not strong.Generally,qualified PE cling film will melt when the temperature exceeds 110°C,leaving some plastic preparations that cannot be decomposed by the human body.In addition,food containing fat can be wrapped,but it cannot be heated in a microwave oven.Therefore,when food is put into the microwave oven,the wrapped plastic wrap must be removed first.
  The number"5"represents that the material of the plastic is PP.High temperature resistant,more common in microwave lunch boxes.Can be reused after careful cleaning.Need special attention,some microwave lunch boxes,the box body is indeed made of No.5 PP,but the lid is made of No.6 PS(polystyrene).Since PS cannot withstand high temperatures,it cannot be placed in the microwave together with the box..To be safe,remove the lid of the container before putting it in the microwave.
  The number"6"represents that the material of the plastic is PS.It is more common in bowls of instant noodle boxes and fast food boxes.It is heat-resistant and cold-resistant,but cannot be placed in a microwave oven to avoid the release of chemicals due to excessive temperature.And can not be used to contain strong acids(such as orange juice),strong alkaline substances,because it will decompose styrene monomer which is not good for the human body,which is easy to cause cancer.Therefore,you should try to avoid using fast food boxes to pack hot food.
