What kinds of packaging materials are commonly used in liquor?

The chemical stability of the glass container is very good, and it will not be corroded by alcohol and acid, so it will not dissolve the silicate in the glass into the wine. After long-term storage, alcohol will produce a little organic acid and ethyl acetate with strong aroma, so it is very suitable for storage in glassware. Therefore, most of the wines circulating in the market are white wine in glass bottles.

2. Ceramic containers

Pottery pots, jars and jars are made of clay. Generally, it is round, with a small belly and a big mouth, and it is glazed or glazed. They are traditional wine storage and holding containers in China.

The advantage of ceramic container is that it can maintain the quality of wine and air can easily enter, thus promoting the aging of wine. The longer wine is stored in ceramic containers, the more metals are dissolved, which will make the wine more mature and mellow.

In the same era, the materials and quality of containers are different, and the coloring degree is also very different. In ceramic containers, whether ceramic containers or cement storage tanks with ceramic tiles, the dissolution of calcium is more, followed by magnesium, followed by copper and iron. According to research, these metal ions are dissolved in wine and play an important role in wine aging. ?

3. Blood container

It is a traditional wine storage container in China. It consists of wine sea, wine jar and wine basket. Made of Vitex negundo or bamboo stick, pasted with multi-layer mulberry paper and coated with blood material. There are also wine boxes made of wooden boards or cement pools, which are pasted with layers of mulberry paper and coated with blood as wine storage containers.

The advantage of blood material container is that "blood material" is a kind of plastic protein colloidal salt made of animal blood and lime, which forms a semi-permeable membrane with alcohol. This membrane is characterized by water permeability and alcohol impermeability, and it has a good anti-seepage effect on liquor with an alcohol content of over 30%, and the storage will play a good role in maintaining the quality of liquor. Moreover, local materials are convenient, the cost is low and it is not easy to be damaged.

4. Plastic bucket

At present, the plastic barrel packaging of liquor in the market can be divided into two categories: one is ordinary polyethylene plastic, which is used to pack liquor in barrels. After a long time, polyethylene will be dissolved in alcohol in large quantities, which will cause skin allergy and severe anemia after drinking this wine.

The other is environmentally friendly PET packaging. PET is a new type of polymer polyester material, which has been used to package low-alcohol liquor such as beer abroad. It will not be harmful when it is used to contain liquor, but the alcohol will evaporate slowly after a long storage time. For your own health, please store the wine in the glass container as soon as possible after buying the wine in the plastic barrel.

5. Canned packaging

Beer or other drinks are mostly canned, while liquor has never appeared. In fact, because of the nature of liquor itself, it is not suitable for cans. Liquor contains high alcohol and other chemicals, which may produce substances that react chemically with cans, thus corroding cans and leading to leakage.

Because liquor has no shelf life and a long shelf life, it is necessary to observe liquor by appearance to know whether liquor is crystal clear or turbid. If you put it in a jar, you can't observe it.
