Question 2: Is it harmful to your health to put hot water in Tupperware plastic cups? Tupperware is ok, but it is generally not used. High temperature can be toxic. It is not good to use disposable cups for a long time. Look carefully at the number "01"on the small triangle under your plastic cup-pet.
Mineral water bottles and carbonated beverage bottles are made of this material. Dong Jinshi pointed out that beverage bottles cannot be recycled with hot water. This material is heat-resistant to 70℃ and is only suitable for warm or frozen drinks. It is easy to deform when it is filled with high-temperature liquid or heated, and substances harmful to human body are dissolved out. Moreover, scientists have found that this plastic product may release carcinogens after 10 months, which is toxic to human body. Therefore, drink bottles should be discarded when they are used up. They should not be used as drinking cups or as storage containers for other items, so as not to cause health problems.
"02"-HDPE (high density polyethylene)
Plastic containers for cleaning products and bath products. At present, most plastic bags used in supermarkets and shopping malls are made of this material, which can withstand the high temperature of 1 10℃, indicating that plastic bags for food can be used to hold food. Plastic containers containing cleaning products and bath products can be reused after careful cleaning, but these containers are usually not easy to clean, making the original cleaning products a hotbed of bacteria, and it is best not to recycle them if they are not thoroughly cleaned.
"03"-PVC (polyvinyl chloride)
According to reports, plastic products made of this material are prone to produce toxic and harmful substances from two aspects, one is monomolecular vinyl chloride that is not fully polymerized in the production process, and the other is harmful substances in plasticizers. These two substances are easy to precipitate when they encounter high temperature and oil, and toxic substances are easy to cause cancer after entering the human body with food. At present, containers made of this material are rarely used for packaging food. If it is in use, don't let it get hot.
"04"-LDPE (low density polyethylene)
Plastic wrap and plastic film are both made of this material. Heat resistance is not strong. Generally qualified PE plastic wrap will melt when the temperature exceeds 1 10℃, leaving some plastic preparations that cannot be decomposed by human body. Moreover, food is wrapped and heated with plastic wrap, and the oil in food can easily dissolve the harmful substances in plastic wrap. Therefore, before putting food into the microwave oven, you must first remove the wrapped plastic wrap.
"05"-PP (polypropylene)
The microwave lunch box is made of this material, which is resistant to high temperature 130℃ and has poor transparency. It is the only plastic box that can be put into the microwave oven and reused after careful cleaning. It should be noted that some microwave lunch boxes are made of PP 05, but the lid is PS 06. PS has good transparency, but it is not resistant to high temperature, so it can't be put in the microwave oven with the box. To be on the safe side, open the lid before putting the container in the microwave oven.
"06"-PS (polystyrene)
This is the material used to make instant noodle boxes in bowls and foamed fast food boxes. Heat-resistant and cold-resistant, but it can't be put into the microwave oven to avoid releasing chemicals when the temperature is too high. Moreover, it cannot be used to hold strong acids (such as orange juice) and strong alkaline substances, because it will decompose polystyrene that is not good for human body. Therefore, you should try to avoid packing hot food in fast food boxes.
"07"-PC and other categories
PC is a widely used material, especially for making bottles and space cups. This is controversial because it contains bisphenol A. Experts point out that in theory, as long as bisphenol A is completely converted into plastic structure in the process of manufacturing PC, it means that the product has no bisphenol A at all, let alone released it. However, if a small amount of bisphenol A is not converted into the plastic structure of PC, it may be released into food or drink. Therefore, special attention should be paid when using this plastic container.
The higher the temperature, the more bisphenol A remaining in PC is released and the faster it is. So PC water bottles should not be used to hold hot water. If your kettle number is 07, the following methods can reduce the risk: don't heat it when using it, and don't direct it in the sun. No dishwasher or bowl dryer is needed to clean the kettle. Before the first use, wash it with baking soda powder and warm water, and dry it naturally at room temperature. If the container is injured or damaged, it is recommended to stop using it, because it is easy to hide bacteria if there are tiny pits on the surface of plastic products. Avoid reusing aging plastic appliances.
If you find that your kettle has the above figures, there are the following ways to reduce the risk: before using it for the first time, wash it with baking soda and warm water. Dry naturally at room temperature. Because bisphenol A will release more during the first use and long-term use. & gt
Question 3: Is Tupperware water cup toxic and safe?
1. Tupperware is one of the largest manufacturers of plastic fresh-keeping containers in the world. Its products are made of pure food safety plastics, and have passed the strict inspection of the US Food and Drug Administration (FDA), Japanese Health Association (JPHA) and China Health and Quarantine Department. They are safe and hygienic, resistant to various solvents, such as acid, alkali and salt, anti-aging and have a normal service life of several decades.
2. Tupperware products have been strictly inspected by the US Food and Drug Administration, and meet the standards suitable for food storage in European and American countries, which is the guarantee for the safety of stored food.
The knife and fork sign is a food safety sign. If there is a knife and fork mark on the daily necessities that come into contact with food, it means that the product has passed the test, meets many German and European standards, meets the requirements of German LFGB regulations, and proves that it does not contain toxic substances harmful to human body, and can be sold in Germany and other European and American markets.
4. Other categories-PC, PEI+PET (this is a whole, patented product specially developed by American General Motors, with high temperature resistance 180).
The label of Cai Ying Suixin Cup is 7, and the material is PC, which can be heated and used safely.
5. The color master batch (the pigment of the product) is provided by the designated manufacturer, and does not contain toxic components harmful to human health. Thermoplastic is used, which can be reused for many times, and will not cause permanent garbage, effectively protecting the environment.
Question 4: Tupperware Cup, what material is it made of? Will it be harmful? Tupperware cups are made of PC, and the bottom of the cups is marked with 07, "07"-PCs and other PCs are widely used materials, especially for making baby bottles and space cups. In recent years, bottles have been controversial because they contain bisphenol A. Experts point out that in theory, as long as bisphenol A is completely converted into plastic structure in the process of manufacturing PC, it means that the product has no bisphenol A at all, let alone released. However, if a small amount of bisphenol A is not converted into the plastic structure of PC, it may be released into food or drink. The higher the temperature, the more bisphenol A remaining in PC is released and the faster it is. So PC water bottles should not be used to hold hot water. If the container is injured or damaged, it is recommended to stop using it.
Question 5: Is Tupperware's cup filled with boiling water poisonous? I wonder if it's poisonous. The landlord can see for himself.
Tupperware cups mostly correspond to No.7 new material, and the material is polycarbonate (PC).
Bisphenol A, also known as BPA, is industrially used to synthesize polycarbonate (PC) and epoxy resin. Since 1960s, it has been used to make plastic (milk) bottles, suction cups for children, and inner coatings for food and beverage (milk powder) cans. BPA is everywhere, from mineral water bottles, medical devices to the inside of food packaging. Every year, the world produces 27 million tons of plastics containing BPA. But BPA can also lead to endocrine disorders, threatening the health of fetuses and children. Cancer and obesity caused by metabolic disorders are also considered to be related to this. The European Union believes that bottles containing bisphenol A can induce precocious puberty. From March 2, 20 1 1, it is forbidden to produce baby bottles containing bisphenol A(BPA). (from Baidu Encyclopedia)
In the process of PC synthesis, bisphenol A is its raw material. When fully synthesized, PC should contain no bisphenol A, but there is no residue-free process in industry.
So ... .
Question 6: Is Tupperware's water cup PP plastic or PC plastic? The plastic of PC is poisonous. Can I use it to drink water? Both.
Different materials have different products. You can choose PP when you buy it, because the temperature of PC is too high, which will produce bisphenol amine. So it is only stipulated that baby bottles are not allowed to be made of PC? Other adult food containers can be used, because adults have high resistance and trace amounts are no problem!
