What does the logo on the plastic bottle mean?

Author: mgg-Plastic bottle manufacturer

Each plastic container has a small identity card - a triangular symbol, which is generally at the bottom of the plastic container. There are 1-7 numbers inside the triangle, each number represents a plastic container, and their production materials are different, and there is also different use in use. "No. 1" PET: mineral water bottle, carbonated beverage bottle beverage bottle of carbon carbonated use of hot water use: heat-resistant to 70 ° C, only suitable for warm drink or frozen drink, high temperature liquid, or heating is easy to deform, there is human body Harmful substances melt.

And, scientists found that No. 1 plastic product used for 10 months, may release carcinogens DEHP, which is toxic to the testicular. Therefore, if the beverage bottle is used, it will be lost, do not use it as a water cup, or used to make storage containers to use other items, so as not to cause health problems. "No. 2" HDPE: Cleaning supplies, bathing products cleaning is not thorough suggestion not to recycle: can be reused after being cleaned, but these containers are generally not cleaned, and the original cleaning supplies are residual, become a hotbed of bacteria, you It is best not to recycle.

 "No. 3" PVC: At present, it is best not to purchase in food packaging: this material is high temperature, even if it will be released in the process of manufacturing, and toxicity will be released with food, it may cause Diseases such as breast cancer, newborns congenital defects. At present, the container of this material is relatively small for packaging food. If you are using, don't let it heat.

 "No. 4" LDPE: plastic film, plastic film and other plastic film do not pack the microwave in the surface of the food: is not strong in heat resistance, usually, the qualified PE plastic wrap will have hot melt during the temperature exceeding 110 ° C, Will leave some of the plastic formulations that have not been decomposed. Also, the food is wrapped with a plastic film to heat it, and the fat in the food is easily dissolved in the wrap the harmful substances. Therefore, food into the microwave, first remove the cling film wrapped in the package.

 "No. 5" PP: When the microwave oven box is placed in a microwave, the cover is removed: the only plastic box that can be placed in the microwave can be reused after cleaning. It is necessary to pay special attention, some microwave oven box, and the casing indeed manufactured by PP, but the lid is manufactured in PE, since PE cannot be retroiled to high temperatures, so it cannot be placed in a microwave with the casing. For insurance, the container is removed before the container is placed in the microwave.

 "No. 6" PS: Bowl Bubble Box, Fast food box Buy a microwave boiled bowl instant noodle use: heat resistant and cold, but cannot be put into the microwave to avoid chemicals due to high temperature. And cannot be used to take strong acid (such as a willow orange juice), strong alkaline substance, because it will decompose polystyrene to human body, which is easy to cause cancer. Therefore, you must try to avoid packing hot food with fast food boxes.

 "No. 7" PC Other Class: kettle, water cup, bottle PC glue encounters hot release bisphenol A: A large number of materials, especially in the bottle, because of bisphenol A is controversial. Lin Hanhua, Associate Professor, Associate Professor, Department of Biology and Chemistry, Hong Kong, said that in theory, as long as the bisphenol A is converted into a plastic structure in the process of making PC, it means that the article is complete without bisphenol A, and it will not be released. However, if a small amount of bisphenol A is not converted into a plastic structure of the PC, it may be released to enter the food or drink.

Therefore, be careful, should pay special attention when using this plastic container.
