Plastic bottles are convenient to carry, not afraid of falling, with acid and alkali resistance, convenient production, and also beneficial to recycle. The main raw materials for making beverage bottles are polypropylene plastics, non-toxic and harmless, used to dress a vapor-free drink to have no adverse effects on the human body; but due to the plastic bottle contain a small amount of ethylene monomer, if long-term storage wine, vinegar, etc. Chemical reactions will occur. Long-term consumption of ethylene contaminated food will make people dizziness, headache, nausea, loss of appetite, memory loss, etc., severe people may also lead to anemia.
In addition, with a beverage bottle, wine, vinegar, etc., the bottle will be protected by oxygen, ultraviolet rays, etc., release more ethylene monomers, so that the long-term liquor, vinegar and other deterioration.

After opening, please confirm the drink; 2. When storing non-drinking products, please wake up to avoid mistakes Food. The identification of plastic bottles can utilize infrared spectroscopy, paramagnetic resonance gauges, and X-rays, etc., but can also be identified using a simpler method.
The following is a brief introduction to the simple identification method: sensory identification (organizational students participate in the identification of plastics) (1) Look: First see the color, transparency of the product. Transparent products are: polystyrene and plexiglass. Translucent products are: low density polyethylene, cellulose plastic, polyvinyl chloride, polypropylene, epoxy resin, unsaturated resin.
The opaque products are: high density polyethylene, polyurethane and various colored plastics. (2) Listening: When tapping with hard items, the sound is different, and the polystyrene is like a metal sound, and the organic glass is very rough. (3) Touch: It is necessary to use the wax shape with hand to touch the product.
