Nowadays, many people are demanding higher and higher quality of life. They are more and more aware of the environmental protection of daily necessities and the food level. Especially the containers and other daily necessities that come into contact with food, not only are they fastidious about the appearance, but also pay more attention to whether they meet the hygiene and health standards, whether they are harmful to the body and so on, instead of just looking at the price to select commodities as before.
Many people think that as long as plastic water bottles are toxic and harmful, ordinary drinking water and other containers in contact with drinking liquids will not choose to use plastic products. Some people think that (new) plastic water bottles are harmful to human body just because they have a small amount of odor (some odor of new unused plastic water bottles is normal phenomenon, regular plastic water bottle sellers have instructions for odor removal). So many consumers who don't know much about plastic water bottles have such a misunderstanding.
Next, I'll tell you about the raw materials of plastic water bottles, their fabrication and the characteristics of plastic water bottles.
At present, the common raw materials of plastic water bottles are: PP, PE, AS, PS, ABS, PET, PETG, PCTG, PC (containing bisphenol A), TRITAN. PC is a kind of plastic raw material which is widely used in the market at present. Its physical properties are very good. Whether it is high temperature resistance or impact resistance, or anti-fall or toughness, it is very good. At present, only TRITAN material can match it, even PC is better than TRITAN in characteristics. But PC material has a fatal disadvantage, that is, it contains BPA (Bisphenol A is the main synthetic component of PC materials.)
Animal experiments have found that bisphenol A can mimic estrogen. Even at very low doses, bisphenol A can induce premature female puberty, decrease sperm count and increase prostate. In addition, some data show that bisphenol A has certain embryotoxicity and teratogenicity, and can significantly increase the incidence of ovarian cancer, prostate cancer, leukemia and other cancers in animals.
Therefore, American Eastman Company has developed TRITAN material, environmental protection, food grade, BPA FREE. At present, the market is one of the very good raw materials for plastics, and it has successfully replaced PC as one of the main materials for plastic water bottles.
2. Production process.
Any factory, as long as it is in contact with food products, containers and so on, the state requirements are relatively strict. Therefore, in the selection, regular and large-scale factories should be more reliable and more secure.
Plastic water bottle production, first of all, the need to produce the water bottle mold installed in the machine, the machine after the necessary cleaning and other work, ingredients, color mixing, machine testing, product requirements can be batched, can not reach, continue to debug repeatedly until the standard, and then printing, assembly, packaging finished products. If it is a regular and qualified factory, there will be clear regulations on employees'clothing, operation, and dust-free workshop.
3. Characteristics of Plastic Water Bottle
1) Not easy to break, lighter weight.
2) Better stability than stainless steel bottle, not easy to be corroded by acid and alkaline beverages, much lighter than stainless steel bottle, travel more convenient, hot water, poor thermal conductivity has become an advantage.
3) Most plastic water cups can be recycled. They can be used repeatedly after being made into raw materials. They are environmentally friendly and do not pollute the environment. There is a limit to any product. When purchasing plastic water bottles, you need to know more about the use of water bottles from sellers.
