Meaning of disinfection tableware numbers

Modern people pay more and more attention to food safety, among which tableware is the most important. Therefore, most dining halls will use sterilized tableware for people to use, but when we choose tableware, it is often found that there are different numbers at the bottom, so in order to facilitate our correct selection, the following will introduce the specific meaning of the numbers. There is a triangle with an arrow at the bottom, which is the 'regeneration' sign, and there is a triangle from 1- The Arabic numerals of 7 and the difference of Arabic numerals represent the different properties and different uses of this material. It seems that small tableware has such great knowledge, if you want to know more about it, look down together: the number '1' of disinfection tableware represents that the material is PET, I . e. polyethylene terephthalate, common mineral water bottles, carbonated beverage bottles, etc. , which is heat resistant to 70 ℃ and easy to deform, dissolution of substances harmful to human body; After 10 months of use, the carcinogen DEHP may be released; Can't put it in the car to bask in the sun, can't contain wine, oil and other substances, this kind of logo bottle can't continue to hold water after use, please throw it in the recyclable dustbin and let it be recycled. Disinfection tableware number '2' represents that the material is HDPE, which is commonly used for packaging bottles of cleaning products and shower products, and is not used for food packaging. The number '3' represents that the material is PVC, which is easy to produce harmful substances when it is in high temperature, and even it will be released during the manufacturing process, after a poison enters the human body with food, it may cause breast cancer, neonatal birth defects and other diseases. At present, the container of this material has been rarely used for packaging food. If it is in use, never let it heat up. The number '4' represents that the material is LDPE, and the general products are plastic wrap, film, etc. The heat resistance is not strong. Generally, qualified PE plastic wrap will have hot melting when the temperature exceeds 110 ℃, some preparations that cannot be decomposed by human body will be left, and food wrapped with plastic wrap will be heated, and the grease in food will easily dissolve the harmful substances in the plastic wrap. Therefore, food is put into the microwave oven, first, remove the wrapped plastic wrap. The number '5' of disinfection tableware represents that the material is PP, which is resistant to high temperature and is mostly found in microwave lunch boxes. It can be reused after careful cleaning and requires special attention. Some microwave lunch boxes, the box body is indeed made of No. 5 PP, but the box cover is made of No. 1 PE. Since PE cannot withstand high temperature, it cannot be put into the microwave oven together with the box body. To be on the safe side, remove the lid from the container before placing it in the microwave oven. The number '6' represents that the material is PS, which is mostly found in bowl-packed instant noodle boxes and fast food boxes. It is heat-resistant and cold-resistant, but it cannot be put into a microwave oven to avoid releasing chemicals due to too high a temperature, and can not be used to contain strong acid, strong alkaline substances, because it will break down the bad polystyrene on the human body, easy to cause cancer, therefore, you should try to avoid using fast food boxes to pack hot food. Disinfection tableware number '7' represents the material other than PVC and polystyrene or synthetic materials of various materials, which are mostly found in kettles, cups and feeding bottles. It is resistant to high temperature and can be used repeatedly, but can not be put into the microwave oven to heat. The number of disinfection tableware indicates what the tableware material is, so that we can understand the applicable occasions of different materials and the matters needing attention, only in this way can it be convenient for us to choose tableware with appropriate materials according to our own needs, thus avoiding accidents caused by wrong choices.
