Almost every household has plastic bottles. Besides saving them and selling them for money, they are often used for “recycling” such as cooking oil, grains, etc. But did you know that?If improper plastic bottles to save, use a long time is likely to produce harmful substances, and damages health plastic use undeserved cause cancer? A lot of friends say plastic bottle labeled “1” at the bottom of the bottle is a one-off, if repeated use, separating out of plasticizer which is easily causes the DNA mutations in the body, may even increase the risk of some cancers.In fact, the “triangle + number” logo is the symbol code of the type of plastic used by the American Plastics Industry Association, which can make the type of plastic easy to identify, and the cost of recycling will be greatly reduced.General transparent mineral water bottle bottom will be marked with the word “1”, its material is mainly “PET”, full name is “polyethylene terephthalate”, this kind of material can be heat resistant to 70℃ or so, the use condition is generally in -20℃ to 70℃ or so, this plastic bottle is not recommended excessive repeated use, it is best to use one or two do not use again,But many families like to use it to hold cooking oil, spices and so on, and put it on the hearth, the temperature is high, may bring health risks.Plasticizers, or plasticizers, are added to hard plastics to increase elasticity and durability.Phthalate esters (DEHP) are the most commonly used plasticizers.As for plasticizer, it is allowed to be used in the production of food packaging materials as long as it meets the requirements of the usage, residual amount and migration amount of plasticizer in all countries in the world.So, do plasticizers cause cancer?The World Health Organization’s Center for Cancer Research classifies “DEHP” as a Group 2B carcinogen, which is defined as “a substance that is likely to cause cancer in humans, but with limited or insufficient evidence.”While represented by DEHP plasticizer, there are possible under certain conditions, migration from some plastic products to the food and ultimately into the human body, but the DEHP in the use of food packaging is strictly limited, its migration quantity does not reach the dose of harmful, in addition its insufficient evidence of carcinogenicity itself to the human body.So, “plasticizer carcinogenic” also need to look at science.There are seven types of plastics commonly used at present, which are found in the following articles. The plastic products marked 1, 2, 4 and 5 are safer.Material products use common attention polyethylene terephthalate beverage bottle, bottled water, the heat resistance of supplies to 70 ℃ is easy deformation, using 10 months may release carcinogens, with one or two more safety, do not recommend excessive repeated use of high density polyethylene food and pharmaceutical packaging and clean, bath products, such as yogurt, chewing gum, shower gel bottles is not easy to clean,It is not recommended to recycle PVC plastic bags, table MATS, toy yellow ducks, rope skipping, rubber when exposed to high temperature and grease, harmful substances will be released. It is not recommended to contact food low-density polyethylene plastic film, plastic bags, toothpaste and other flexible packaging to avoid high temperature.Do not contact greasy food polypropylene crisper, plastic fast-food box, straws, toys, washbasin and other 110℃ or more deformable polystyrene fast-food box, transparent packaging box, disposable plastic tableware, self-service tray, to avoid high temperature,There is a risk of “styrene” residue other cups, mineral water buckets, suitcases, yoga MATS, porcelain imitation tableware, in addition to Tritan(copolymer of polyester), should not touch food plastic products safety rules 1.Many people use mineral water bottles as versatile containers for wine, oil and so on.● Plastic bottles are not too dangerous for oil, but should not be placed in overheated places, such as beside the stove, and should be replaced regularly.● Alcohol is best avoided in plastic bottles, as alcohol dissolves plastic.2. Plastic containers: choose no odor, no black spots when buying plastic containers and other products, smell whether there is a scorch smell, see whether there are scorched black spots.If there is, the basic can be confirmed to be made with recycled waste, especially food packaging and other contact with food or human body, as little as possible.Try to choose a bigger brand.3. Plastic bags: Choose plastic bags with smooth surface and crisp sound for daily use. There are two most common materials, respectively PVC (No. 3) and PE (No. 4).● PVC (No. 3) : it feels sticky and astringent. Shake it with your hands and the sound is small and stuffy.● PE (No. 4) : more lubrication to touch, toughness, vibration sound brittle, high safety contact with all kinds of food, but not suitable for high temperature heating, such as hot water, microwave oven.4. Try to avoid heating packaging boxes. Lunch boxes are very common in daily life, and there are two main categories of materials.● Foaming polystyrene (No.6) : poor heat resistance, can not be heated.● Polypropylene (No. 5) : The meal box is thin and transparent, allowing microwave heating.However, it is difficult for ordinary consumers to distinguish between these two types of meal boxes, and it is recommended not to microwave heating.Source: Science China
