Nowadays, glass bottles are irreplaceable in all kinds of food packaging, regardless of material, health, price, transportation and other factors. Especially wine, high-end drinks and olive oil.
As we all know, high-end products want to taste good, have a long shelf life, and use as few food additives as possible. In this way, the only thing that does not affect the taste of the product and is harmless to the human body is vacuum packaging of the product. Because of the high coefficient of thermal expansion and contraction of plastic bottles, the bottles need to undergo high temperature disinfection. Plastic bottles will deform when exposed to high temperature, and a large number of plasticizers harmful to the body will be volatilized, resulting in the products that people can not eat at all. This high-temperature disinfection and vacuum canning method can only be used on glass bottles. The iron bottle is not beautiful because it is opaque. Moreover, the thermal conductivity of iron is faster, and it is extremely vulnerable to the influence of external environmental temperature on product taste and shelf life. At the same time, it is abandoned for many reasons, such as high price, long time and easy to rust.
After screening by various conditions, the only packaging that meets various conditions is glass bottles.
First, the glass bottle will not produce harmful substances at high temperature;
Second, the glass bottle will not deform at high temperature and rust after a long time;
Third, glass bottles are cheap, recyclable and non-polluting
Fourth, the color of the glass bottle is controllable, can block light, can be transparent, high-end and fashionable.
