Plastic bottle safe use and warning

The plastic bottle is easy to carry, not afraid of falling, has acid and alkali resistance, is convenient to produce, and is also convenient for recycling.

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 and taste. For beverages that do not contain other liquids, it is recommended that the beverage company indicate the following warnings in the bottle packaging:

Warning: 1. After opening, please confirm and drink again; 2. When storing non-drinking supplies, please wake up to avoid accidental eating.

The identification of plastic bottles can be done by scientific methods such as infrared spectrometer, paramagnetic resonance, and X-ray, but it can also be identified by a relatively simple method. The following briefly describes the simple authentication method:

Sensory identification (organizing students to participate in the identification of plastics)

(1) Look: First look at the color and transparency of the products. Transparent products are: polystyrene and plexiglass. Translucent products are: low density polyethylene, cellulose plastic, polyvinyl chloride, polypropylene, epoxy resin, unsaturated resin. Opaque products are: high density polyethylene, polyurethane and various colored plastics.

(2) Listening: When tapping with hard objects, the sound is different, polystyrene is like metal sound, and the sound of plexiglass is thick and boring.

(3) Touch: Touching the product by hand feels like waxy, it must be polyolefin material
