In fact: plastic food bottles and containers have a "shelf life"

in summer, many people drink bottled drinks, and some beautiful plastic bottles used are often reused, or filled with water, oil, etc. Is such "environmental protection" and "saving" really safe? According to the interview, many consumers still have many misunderstandings when using plastic catering products

aunt Cao, a citizen, saw a plastic bottle of 100% fruit juice that her daughter had drunk some time ago. It looked good and looked of good quality, so she washed and made her own kettle. She told me that every morning she likes to decorate tea and go out for morning exercises. The bottle is very heat-resistant, and the boiling water won't deform when poured down. After using it for more than 2 weeks, she once filled it with boiled water in the morning. When she opened it, she smelled a strange smell and felt a little worried

recently, Mr. Yan, who has been engaged in chemical experiments for many years, told that qualified beverage bottles and mineral water bottles should be made of food grade plastic, and the main ingredient is pet. These food grade PET bottles cannot withstand high temperature at present, and need to be used at low temperature. Generally, it is safe to use them below 70 ℃. These plastic bottles are disposable, and the state stipulates that enterprises cannot recycle and refill them for use. For some people like to use it as a kettle, he doesn't recommend it. Because the harmful substances in plastic will dissolve out and enter the water when encountering high temperature water. Moreover, if mineral water bottles or beverage bottles are used repeatedly, the sanitary indicators cannot be reached. When filling for the first time, the enterprise has carried out strict disinfection, cleaning, sterilization and other procedures for bottles, but when consumers repeatedly use bottles, they have not gone through these hygiene procedures, which is neither hygienic nor safe

it is also understood that at present, China uses triangle symbols as plastic recycling marks. There are 1-7 numbers in the triangle, and each number represents different materials. Therefore, different numbers in the recycling sign indicate which resin the product is made of. If the product is made of several different materials, it indicates the main and basic materials of the product. However, in China, because the recycling mark of plastic products is not mandatory, not all manufacturers have marked it at present

recently visited a supermarket in the urban area. It is found that the bottom of mineral water bottles on the market are basically marked with the number "1". The number "2" can be seen at the bottom of most yogurt. Do you want to speed up the upgrading of plastic granulator technology for the bottle bottom of some tea drinks or functional drinks? There is no plastic material label, or the label is not clear, which can be seen only after careful identification. On another shelf, there are many plastic kettles and special plastic lunch boxes for microwave ovens. Casually picked up a plastic water bottle for children with a beautiful "Mickey Mouse" pattern, and found that there was no clear range of high and low temperatures that the water bottle was subjected to, and the plastic components had been covered by a large trademark. If it was not torn off, no one would notice it at all. However, on the trademark, note that the manufacturer of winding testing machine introduces the operation knowledge, and the shelf life of Ming kettle is three years. A parent who was buying school supplies for his children also noticed the "Mickey Mouse" kettle. After reading the trademark, he was surprised and said, "I didn't expect that the plastic kettle also has a shelf life! But does this shelf life start from the date the plastic kettle leaves the factory or the date of use? It would be better if there was a specific production and shelf life date like food."
