The main raw material for making beverage bottles is polypropylene plastic, which is non-toxic and harmless. It is used to hold soda and cola beverages without adverse effects on the human body. However, because plastic bottles still contain a small amount of ethylene monomer, if they are stored for a long time, they are fat-soluble such as wine and vinegar. Organic matter, a chemical reaction occurs. Eating food contaminated with ethylene for a long time can cause dizziness, headache, nausea, loss of appetite, memory loss, etc. In severe cases, it may also lead to anemia. In addition, using beverage bottles to hold wine, vinegar, etc., the bottles will be aged by oxygen, ultraviolet rays, etc., releasing more ethylene monomers, which will deteriorate the wine, vinegar, etc. stored in the bottle for a long time. For the accident that the beverage bottle should not be filled with other liquids and cause accidental injury, it is recommended that beverage companies indicate the following warnings on the bottle packaging:
Bottom of the bottle logo
Bottom logo
"No. 1" PETE
Mineral water bottle, carbonated beverage bottle
Beverage bottles should not be recycled or filled with hot water.
Use: Heat-resistant to 70°C, only suitable for warm or frozen drinks, easy to deform when filled with high-temperature liquid or heated, and there are substances harmful to the human body melted out. In addition, scientists found that after 10 months of use, plastic No. 1 may release the carcinogen DEHP, which is toxic to the testicles.
"No. 2" HDPE
Cleaning products, bath products
Cleaning can not be thorough, it is recommended not to recycle.
Use: Can be reused after careful cleaning, but these containers are usually not easy to clean, leaving the original cleaning supplies and becoming a breeding ground for bacteria, it is best not to recycle.
"No. 3" PVC
Rarely used in food packaging, it is best not to buy.
"No. 4" LDPE
Cling film, plastic film, etc.
Do not put plastic wrap on the surface of food and heat it in the microwave.
Use: The heat resistance is not strong. Usually, when the temperature exceeds 110 °C, the qualified PE plastic wrap will appear hot melt, leaving some plastic preparations that cannot be decomposed by the human body. In addition, when the food is heated by wrapping the plastic wrap, the oil in the food can easily dissolve the harmful substances in the plastic wrap. Therefore, when the food is put into the microwave oven, the wrapped plastic wrap must be removed first.
"No. 5" PP
microwave lunch box
When placing in the microwave, the lid should be removed.
Use: The only plastic box that can be placed in the microwave and can be reused after careful cleaning. Special attention should be paid to some microwave lunch boxes. The box body is indeed made of No. 5 PP, but the lid is made of No. 1 PE. Since PE cannot withstand high temperatures, it cannot be put into the microwave oven together with the box body. To be on the safe side, remove the lid before placing the container in the microwave.
"No. 6" PS
Bowl of instant noodle box, fast food box
Do not cook instant noodles in bowls in the microwave.
Use: It is heat-resistant and cold-resistant, but cannot be placed in a microwave oven to avoid the release of chemicals due to excessive temperature. And it cannot be used to hold strong acids (such as orange juice) and strong alkaline substances, because it will decompose polystyrene that is not good for the human body, which is easy to cause cancer. Therefore, you should try to avoid packing hot food in snack boxes.
"No. 7" PC
Other categories: Kettles, drinking glasses, feeding bottles
