A simple rule for using plastic utensils is to use them only once. The most famous carcinogen in the world is polyvinyl chloride (PVC). It is an extremely cheap chlorine-based polymer and is therefore the most commonly sold. Water bottles, cosmetic boxes, packaging for household chemicals and other disposable containers are made from this polymer. Over time, PVC begins to release a harmful substance (vinyl chloride). From the bottle, vinyl chloride reaches the water, from the plate into the food, from the food into the human body. Each plastic cracks in the light and melts from the heat. Therefore, stabilizers (polystyrene or polypropylene) are placed in the plastic for strength. This makes the plastic stronger.
Plastic polystyrene (PS) is resistant to cold liquids. If you pour a hot drink of 70 degrees and a multi-harmless glass into it, it starts releasing a toxic compound that is deposited in the liver and kidneys due to regular use. Hot dishes should not be placed on fragile and easily breakable polystyrene plates, because heating these dishes releases toxic compounds. Polypropylene pan (PP) can withstand temperatures from 100 to 140 degrees C. It can be used to heat food in a microwave oven. It is suitable for alcoholic beverages because polypropylene is resistant to alcoholic solutions. Styrofoam dishes or styrofoam dishes have the same quality and retain heat well.
You can distinguish hazardous PVC products from harmless plastics by reading the back of the product. Conscientious manufacturers put a triangle sign with the number 3 inside the bottom of dangerous bottles or write PVC. Take a small test. The safest way to check the harmfulness of plastic is to scratch the bottle with your fingernail. A whitish mark will form on the bottle if the bottle is harmful. The harmless polymer bottle will stay smooth. Disposable cutlery should have the sign “glass with a fork” on the back. This is a guarantee that the product can be in contact with food. If plastic cutlery doesn’t have any labels — refrain from buying. The label “PET” means that the product can be used several times. The number of the certificate should be indicated on the packaging or special base, because the production of disposable tableware is subject to mandatory certification. Pay attention to the date of manufacture. Dishes older than a year – do not buy.
Disposable containers made of paper are also the safest to use. They do not emit a harmful substance and do not endanger the environment. Although they become unusable during wetting, the most important thing for people is that they are safe for their health. Laminated paper containers (white, colorless or with a picture) are more durable. They are especially suitable for children’s parties and youth parties / gatherings.
