The advantages of glass bottles for beer ?
Glass bottle is a traditional beverage packaging container in China, and glass is also a kind of packaging material with a long history. With many packaging materials pouring into the market, glass containers still occupy an important position in beverage packaging, which is inseparable from its packaging characteristics that other packaging materials cannot replace.
The advantages of glass packaging containers in the packaging field:
1. The glass material has good barrier properties, which can prevent oxygen and other gases from attacking the contents, and at the same time prevent the volatile components of the contents from volatilizing in the atmosphere;
2, glass bottles can be used repeatedly, which can reduce packaging costs;
3, the glass can easily change the color and transparency;
4. The glass bottle is safe and hygienic, has good corrosion resistance and acid corrosion resistance, and has the advantages of heat resistance, pressure resistance, and cleaning resistance. It can be sterilized at high temperature or stored at low temperature. Suitable for packaging of acidic substances (such as vegetable juice drinks, etc.);
5. In addition, since glass bottles are suitable for the production of automatic filling production lines, the development of domestic glass bottle automatic filling technology and equipment is also relatively mature, and the use of glass bottles for packaging fruit and vegetable juice beverages has certain production advantages in China.
It is precisely because of the many advantages of glass bottles that they have become the preferred packaging materials for many beverages such as beer, fruit tea, and jujube juice. 71% of the world’s beer is bottled in glass beer bottles, and China is also the country with the highest proportion of glass beer bottles in the world, accounting for 55% of the world’s glass beer bottles, exceeding 50 billion every year.
As the mainstream packaging of beer packaging, glass beer bottles have gone through the vicissitudes of beer packaging over the past century. They are still favored by the beer industry for their stable material structure, non-polluting, and low price. When it looks and feels cold to the touch, glass bottles are the preferred packaging. Generally speaking, glass bottles are still the usual packaging used by beer companies. “It has made a huge contribution to beer packaging and most people like to use it. .
Why are most glass beer bottles with green or brown color?
Summer is the beer carnival season, but have you noticed that although there are brown, blue, and colorless beer bottles in the market, they are mostly green bottles. Why are beer bottles green?
The choice of this color is basically a market reason, depending on the manufacturer’s market strategy at the time, but there are some traditions.
The history of beer is very long, but the time to put beer in glass bottles is not very long, it is about the mid-19th century. At that time, there were no special beer bottles, and wine bottles were more likely to be used. There may be more green bottles in this period. It is important to know that the color of glass depends on the manufacturing process in that year, and it is not what color you want. Therefore, by the end of the 19th century, when there were special beer bottles, the tradition of green bottles was preserved.
Until the 1930s, it was discovered that if the beer is packed in a brown bottle, it can make the beer taste better after being left for a while. The reason was discovered later. Light can promote the reaction of alpha acid in beer with sulfide, which makes the taste very bad. Using a brown bottle can prevent this reaction from happening, and the taste is better. Therefore, more beer is used in brown bottles.
After World War II, there was a period of lack of brown bottles in Europe, so some of the better brands of beer in Europe were repackaged in green bottles. Because these beers are indeed of very good quality, for a time green bottle beer has become synonymous with high-quality wine tasting, so more manufacturers have followed up and used green bottles. At this time, with the popularization of refrigerators and the advancement of sealing technology, the necessity of using brown bottles is basically gone, and it will not bring better quality than bottles of other colors. However, an old brand of beer will not easily change the packaging significantly. At most, adjustments are made to the glass processing technology to make the color more pure and bright or whatever. A major change in the packaging color of a mature brand should be rare. Therefore, Brown and green are still the mainstream of beer packaging.
