How can we clearly understand the brand outside the granular packaging bag

the small recycling logo at the bottom of plastic products is like a small ID card of each plastic container. They are made of different materials and have the same use

“01” – Pet (polyethylene terephthalate) mineral water bottles and carbonated beverage bottles are made of this material. Dong Jinshi pointed out that beverage bottles cannot be recycled to contain hot water. This material is heat-resistant to 70 ℃, and is only suitable for warm or frozen drinks. When containing high-temperature liquid or heating, it is easy to deform and dissolve substances harmful to human body. In addition, scientists found that after 10 months of use, this plastic product may release carcinogens and be toxic to human body. Therefore, drink bottles should be discarded when they are used up. They should not be used as water cups or storage containers to hold 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 110 ℃ high temperature. The plastic bags marked for food can be used to contain food. Plastic containers containing cleaning products and bath products can be reused after careful cleaning, but these containers are usually difficult to clean, leaving the original cleaning products and becoming a hotbed of bacteria. If the cleaning is not complete, it is best not to recycle them

“03” — PVC (polyvinyl chloride) it is reported that the toxic and harmful substances easily produced by plastic products made of this material come from two aspects: one is the monomolecular vinyl chloride that has not been fully polymerized in the production process, and the other is the harmful substances in plasticizers. These two substances are easy to precipitate when encountering high temperature and oil. After the toxic substances enter the human body with food, they are easy to cause cancer. At present, the containers of this material have been less used to package food. If in use, do not let it be heated

“04” — LDPE (low density polyethylene) fresh-keeping film and plastic film are all made of this material. The heat resistance is not strong. Generally, the qualified PE fresh-keeping film will melt when the temperature exceeds 110 ℃, leaving some plastic preparations that cannot be decomposed by the human body. Moreover, wrap the food with plastic wrap and heat it. The oil in the food can easily dissolve the harmful substances in the plastic wrap. Therefore, when putting food into the microwave oven, first remove the wrapped preservative film

“05” — PP (polypropylene) microwave oven lunch box is made of this material, with high temperature resistance of 130 ℃ and poor transparency. It is the only plastic box that can be put into the microwave oven and can be reused after careful cleaning. It should be noted that for some microwave oven lunch boxes, the box body is made of No. 05 PP, but the box cover is made of No. 06 PS (polystyrene). PS has good transparency but is not resistant to high temperature, so it cannot be put into the microwave oven together with the box body. To be on the safe side, remove the lid before putting the container into the microwave oven

“06” — PS (polystyrene), which is used to make bowl instant noodle boxes and foamed fast food boxes. It is heat-resistant and cold resistant, but it cannot be put into the microwave oven to avoid releasing chemicals due to high temperature. And can not be used to contain strong acids (such as orange juice) and strong alkaline substances, because it will decompose polystyrene which is bad for human body. Try not to pack your food in a hot box

“07” — PC and other types of PC are widely used materials, especially in the manufacture of milk bottles and space cups, which are controversial because they contain bisphenol A. Experts pointed out that in theory, as long as bisphenol A is 100% transformed into plastic structure in the process of making PC, it means that the product has no bisphenol A at all, let alone release 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 drinks. Therefore, pay special attention when using this plastic container& lt; BR>& nbsp;& nbsp;& nbsp; The higher the temperature, the more and faster the release of BPA in PC. Therefore, do not use a PC water bottle to hold hot water. If your kettle number is 07, the following methods can reduce the risk: do not heat it when using it, and do not expose it to direct sunlight. Do not use dishwasher or dryer to clean the kettle. Before the first use, wash with baking soda and warm water and dry naturally at room temperature. If the container has any fall or damage, it is recommended to stop using, because if there are fine pits on the surface of plastic products, it is easy to hide bacteria. Avoid repeated use of aged plastic appliances

the following are some common plastic products. They may not carry any recycling identification code, but they still have recycling value. Most recycling bins accept these items, so if you happen to have these plastics, make sure they can be recycled
