Do you know which of the following plastic environmental labels
The conditions vary depending on the material, and this little recycling sign on the bottom of the plastic is like a little ID card for each plastic container,
They are made of different materials and used in the same way.
01 "a PET (polyethylene terephthalate = alcohol ester) mineral water bottles, carbonated beverage bottles are made of this material. drink
The hot water can not be recycled in the bottle. The heat resistance of this material can reach 70°C, which is only suitable for warm or frozen drinks. When it is loaded with high temperature liquid or heated, it is easy to deform.
There is a dissolution of substances harmful to human health. And scientists found that after 10 months of use, the plastic could release carcinogens, right
The human body is toxic. So when you're done, throw it away. Don't use it as a water cup, or use it as a storage container for anything else
Items, in order to avoid hair bow | health problems do more harm than good.
"02" A HDPE (high density polyethylene) bearing cleaning supplies, bath products in plastic containers, currently available in supermarkets and shopping malls 。The plastic bags used are mostly made of this material, which can withstand 110°C high temperature. The plastic bags marked with food can be used to contain food. For cleaning purposes
Plastic containers of products and bath products can be reused after careful cleaning, but these containers are usually not easy to clean, leaving the original cleaning use Product, become a hotbed of bacteria, cleaning is not thorough, it is best not to recycle.
"03"PVC(polyvinyl chloride) according to the introduction, this material of plastic products easy to produce toxic and harmful substances from two sides
Surface, - is the production process has not been completely polymerized monomolecular vinyl chloride, the second is the harmful substance in the plasticizer. The two substances meet high Mild oil is easy to precipitate, poison with food into the human body, easy to cause cancer. Previously, containers of this material have been used less frequently Packaged food. If in use, do not allow it to get hot.
"04 "a LDPE (low density polyethylene) plastic wrap, plastic film and so on are this material. Heat resistance is not strong, generally, qualified
PE wrap at temperatures above 110°C will appear hot melt phenomenon, will leave some plastic preparations that the human body can not decompose. And, with insurance Food wrapped in fresh film is heated, and the fat in food is easy to dissolve the harmful substances in the film. So, the food goes into the microwave, first。You need to remove the plastic wrap.
05 "a PP (polypropylene) microwave lunch box made of this material, resistance to 130°C high temperature, poor transparency, this is the only
A plastic case that can fit in the microwave; It can be reused after careful cleaning. Need special attention is that some microwave lunch box, box body to
05 PP manufacturing; But the box cover is made of No. 06 PS(polystyrene)), PS transparency is good, but not resistant to high temperature, so it cannot be with the box body。Put it in the microwave. To be on the safe side, remove the lid from the container before putting it in the microwave.
"06 "a PS (polystyrene) This is used in the manufacture of bowl instant noodle box, foam fast food box material. It's heat-resistant and cold-resistant, but
Do not put in the microwave to avoid the release of chemicals due to excessive temperature. And can not be used to contain strong acids (such as orange juice), strong alkalinity Quality, because it will break down the human body is not good for polystyrene. Therefore, you should try to avoid packing scalding hot food in fast food boxes.
"7" -A PC and other types of PC is a material that is widely used, especially in the manufacture of baby bottles, space cups, etc., because
Contains bisphenol A, which is controversial. Experts point out that, in theory, as long as the process of making A PC, bisphenol A is 100 percent converted into plastic knots Structure, means that the product is completely free of BPA, let alone release. But if A small amount of BPA isn't converted into the plastic structure of PC,May be released into food or drink. Therefore, take extra care when using this plastic container. Residual bisphenol A in PC, warm
The higher the degree, the more it releases and the faster it goes. Therefore, hot water should not be served in PC water bottles. If your kettle number is 07, here's how Reduce risks: Do not use heat: do not use in direct sunlight. Clean the kettle without using the dishwasher or the dish dryer. Before the second use, use small Wash baking soda with warm water and dry naturally at room temperature. If the container has any falls or breaks, it is recommended to stop using it because of plastic productsIf there is a fine surface pit, easy to hide bacteria. Avoid repeated use of aging plastic appliances.
