The main raw material for making beverage bottles is polypropylene plastic, which is non-toxic and harmless. It has no adverse effect on the human body when it is used for containing soda cola beverages. However, since plastic bottles still contain a small amount of ethylene monomer, if long-term storage of alcohol, vinegar and other fat-soluble Organic matter, a chemical reaction occurs. Long-term consumption of food contaminated with ethylene can cause dizziness, headache, nausea, loss of appetite, memory loss, etc., and severe cases may also lead to anemia. In addition, the bottle is filled with wine, vinegar, etc., and the bottle is aged by oxygen, ultraviolet rays, etc., releasing more ethylene monomer, so that the wine, vinegar, etc. stored in the bottle for a long time deteriorate.
