Plastic bottles are mainly made of polyethylene or polypropylene and other materials with the addition of various organic solvents. Plastic bottles are widely used polyester (PET), polyethylene (PE), polypropylene (PP) as raw materials, after adding the corresponding organic solvent, after high temperature heating, through plastic mold through blow molding, extrusion blowing, or injection molding plastic containers.

Mainly used for liquid or solid disposable plastic packaging containers for beverages, food, pickles, honey, dried fruits, edible oil, agricultural and veterinary drugs, etc. Plastic bottles have the characteristics of being unbreakable, low cost, high transparency, and food-grade raw materials.

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. In the event of accidental injury caused by not filling beverage bottles with other liquids, it is recommended that beverage companies indicate the following warnings on the bottle packaging.
