Nowadays, glass bottles cannot be replaced by any material in all kinds of food packaging, especially the two major ingredients, pickles and edible oil. Everyone knows that high-end pickle bottles must be vacuum-packed if they want to taste good and have a long shelf life,glasscookware. Extending the shelf life of food additives is harmful to the human body. The only thing that does not affect the taste and is harmless to the human body is vacuum packaging. The important factor of vacuum packaging is the high temperature cooling to achieve the vacuum effect. The high temperature cooling of plastic bottles cannot achieve vacuum, because plastic bottles Thermal expansion and contraction, the bottle will be deformed after high temperature, and a large amount of plasticizer will be volatilized, which cannot be eaten by the human body at all. This high-temperature vacuum method can only be done with glass bottles or iron products. And the price is relatively expensive, so there are no manufacturers using iron products to contain pickles on the market. There are so many screenings, and the only packaging is glass bottles. First: the high temperature of glass bottles will not produce harmful substances, and second: the high temperature of glass bottles will not produce harmful substances. It will be deformed, so the pickles we see in the supermarket are basically canned in glass bottles.
