Identification method for biobased fruit fork

Wide mouth plastic bottles are easy to carry, not afraid of falling, with acid and alkali resistance, easy production, but also conducive to recovery.

The main raw material for making beverage bottles is polypropylene plastic, which is harmless, and is used for serving soda and cola drinks without adverse effects on the human body; However, because the plastic bottle still contains a small amount of ethylene monomer, if the storage of fat-soluble organic matter such as wine and vinegar for a long time, chemical reactions will occur. Eating food contaminated with ethylene for a long time can make people dizzy, headache, nausea, appetite loss, memory loss, etc., and may lead to anemia in severe cases.

In addition, with beverage bottles containing wine, vinegar, etc., the bottle will be subjected to oxygen, ultraviolet and other effects and aging, release more ethylene monomer, so that the wine and vinegar stored in the bottle for a long time. Regarding the accidental injury caused by the beverage bottle not containing other liquids, it is recommended that the beverage company indicate the following warning on the bottle packaging:

Warning: 1. after, please confirm before drinking; 2. When storing non-beverage supplies, please mark them clearly to avoid accidental ingestion.

Plastic bottles can be identified using scientific methods such as infrared spectrometers, paramagnetic resonance meters and X-rays, but they can also be identified by simpler methods.

The following is a brief introduction to the simple identification method:

(1) Look: First look at the color and brightness of the product. Tongming's products are: polystyrene and plexiglass. Semi-transparent products are: polyethylene, cellulose plastics, polyvinyl chloride, polypropylene, epoxy resin, unsaturated resin. Unknown products are: degree polyethylene, polyurethane and various colored plastics.

(2) Listen: When tapping with hard items, the sound is different, polystyrene is like metal sound, and the sound of plexiglass is rougher and dull.

(3) Touch: If the product feels waxy by hand, it must be a polyolefin material.
