Materials from which one-time containers are made are absolutely harmless to people.
It’s true. Plastic containers are made of polymers. Before the launch in mass production in scientific laboratories for a very long time studied the effect of plastic on a person. Technical and food plastic is made from polyvinyl chloride (PVC), polypropylene, polyethylene, polystyrene and polycarbonate. Polymers are inert and non-toxic. If all the rules of use are observed, with proper handling, the dishes made of polymer do not harm the person. In addition, according to legislation, the release of disposable dishes is subject to mandatory certification.
Products made of plastic and polymeric materials can be used repeatedly.
This is not true. Disposable tableware can not be used many times. A bottle of soda can not be used to re-store milk, compote, etc. in it. Since the high temperature of products, ultraviolet, long-term food contact with polymeric materials, oxygen promote the “aging” of plastic. As a result, the polymer material releases harmful substances that are transferred to products stored in such containers. Food becomes toxic, harmful to health. Numerous experts believe that the plastic packaging intended for water storage is completely harmless only in the case of tightness. After opening the bottle (when oxygen enters inside), the chemical composition and plastic, and the liquid stored in it, change.
Materials used in the manufacture of disposable dishes can cause malignant tumors.
It’s true. Only in the case when disposable plastic dishes are stored incorrectly or released to the “underground shop” without observing the standards. In this case, polymeric materials emit toxic substances into the environment. They are very dangerous for human health. If these substances enter the body, then the person’s health deteriorates sharply (there is discomfort, allergy, asthma attacks). Experiments conducted on animals have proved that toxic substances released by polymeric materials can cause cancer. And if they get into the body of a pregnant woman – the cause of the deformity of the child.
Plastic dishes of domestic producers are more qualitative than foreign analogues.
Not always. A big role is played not by the country, but by the producer of the goods. If the enterprise follows all production standards, then the goods, the name of the material from which the goods are made, the area of use of the dishes (for hot, cold, loose products, liquid, etc.) should be indicated on the product.
Glassware and ceramics are environmentally friendly and safer for health.
It’s true. However, plastic has its advantages. Plastic dishes are more convenient to use, it is lighter, does not break. In European countries began to switch to the use of glassware. This is not only due to the toxicity of polymer materials, but also because of the global problem of recycling plastic containers.
Polyethylene bags are suitable for storing any products in the freezer.
Not exactly. Food products can be stored only in specially designed packages (resistant to low temperatures). Otherwise, the packages can release toxic substances that are hazardous to health. Therefore, to freeze vegetables and fruits, it is better to use a special food film. Otherwise, over time, products can pick up dangerous compounds and cause poisoning of the body.
Bottles for babies, made of polycarbonate, are harmless.
No, it’s not. In America they even banned the production of such bottles. And firms that produce such products have accepted the conditions of Americans, but insist on the safety of the above-mentioned goods. And for other countries continue to let in dangerous bottles.The fact is that the polycarbonate contains bisphenol A, which, when the bottle is heated, can migrate to food. By action, it is similar to female sex hormones (estrogen). A false hormone interferes with the work of normal estrogens. Especially it is dangerous for boys. It is able to negatively influence the formation of the sexual system of the future man.
Plastic cutting boards are better and safer for health, because bacteria do not multiply on them.
American microbiologists from the University of Wisconsin dispelled this myth. They managed to prove that wooden cutting boards can even kill harmful food bacteria. It would seem a paradox, but 99.9% of bacteria on wooden boards perished in the first 3 minutes, while on plastic ones their number remained unchanged. Prior to the research it was believed that plastic boards are safer.
Disposable cups can be used not only for water.
Not exactly. First of all, you need to look at the marking of the glass. The plastic itself is a soft material (melts from high temperatures, crackles in the light). Therefore, for stability in plastic, stabilizers are added. From this, it becomes stronger and more toxic. Polystyrene (designated as PS or ABS plastic), polypropylene (PP marking), PVC (PVC, PVC) are used in the manufacture of disposable cups. Polystyrene is inert to cold drinks, but if in a cup made from it to pour, for example, tea, then it begins to release styrene. Styrene accumulates in the liver, kidneys. Can lead to cirrhosis of the liver. PVC decomposes the toxic substance vinyl chloride, which accumulates over time. A month later, several milligrams of vinyl chloride accumulate in the contents of the glass or bottle. Therefore, it is better not to store liquid in PVC bottles and glasses for a long time. In addition, wine, soda, sour juices, hot drinks from plastic containers should not be drunk. Is it dangerous. A simple way to establish the presence of a glass of PVC in the glass is to press the nail onto the wall of the product. If there is a whitish trace on the glass, then it is made of PVC. Polypropylene glass allows you to drink tea from it (can withstand up to + l00 ° C). But if you pour vodka into a glass of this kind, then it starts to release phenol and formaldehyde (dangerous for the liver, kidneys, eyesight). Scientists even conducted a study. Vodka was poured into a plastic glass made of polypropylene. After a couple of minutes, the researchers analyzed the content. In the glass was not vodka, but a chemical solution, dangerous for humans.
The use of melamine in the production of dishes is prohibited.
Yes it is. Use of melanin dishes (melamine-formaldehyde resin) is dangerous for health. This type of plastic is strong and beautiful appearance, made from it, the dishes are similar to ceramic. In addition to formaldehyde, asbestos is added to such products for strength. Formaldehyde and asbestos can cause malignant tumors in humans. To apply a bright pattern on the dishes use special paints (others do not fit) containing heavy metals. The melamine tableware is comfortable, reliable, visually attractive, but very toxic. This dish contains formaldehyde tens of times the norm.
