First, put the wine into the bag, vacuum it with a vacuum extractor, and then press and seal it. Quick and convenient, the whole bottle of wine in the bag not only has good sealing performance, but also does not affect the quality of the collected wine, and can be reused after opening the seal. However, the popularity of this method is not high, but it is indeed a very practical and good way to preserve wine.

2, aluminum foil bag.

This method is seldom used by people. There are two reasons for this. First, the price of this kind of aluminum foil bag will be more expensive. Secondly, the opaque aluminum foil bag is unsightly and you can't see what the wine looks like. So the recognition is not great. But it has good anti-static, anti-oxygen, shielding, moisture-proof, shading and excellent heat sealing performance. This method is relatively used to seal the wine to be drunk, but it is not suitable for the preservation of exhibits.

3. Heat shrinkable film.

Heat shrinkable film is very common and easy to buy, and not many people use this method. Strong mobility, good flexibility, strong impact resistance and tear resistance, not easy to break, not afraid of moisture, large shrinkage. Before sealing, cut the heat-shrinkable film into appropriate size, put it on the assembly, and then shrink it with a hot air blower. This method is simple, but it will age and crack after a long time and need to be re-operated. Not suitable for long-term storage, heat shrinkable film is often changed.

4. Sealing film.

Sealing film, also known as winding film, is a special film product thermoplastic with automatic sealing, formability and good toughness, and is a high-performance waterproof material. The use method is to pinch the bottle cap several times, or stick a circle of transparent glue to seal it automatically. The advantage is that the sealing film is colorless and has little influence on the appearance. The disadvantage is that the material is soft and should be replaced at least once every three years.

5, plastic wrap.

Plastic wrap is a common plastic packaging product for fresh food, and PE wrap is usually used. Usage: pinch the bottle cap around several times, or stick a circle of transparent glue. Disadvantages are not high temperature resistance and short maintenance time. It is more suitable for temporarily storing wine for later drinking, and the plastic wrap needs to be replaced every few years, which is not suitable for exhibitions.

6. Raw material belt.

The raw material belt is often used in the faucet at home, which has the advantages of high temperature resistance, low temperature resistance, corrosion resistance, weather resistance, no deformation, high lubrication, easy adhesion and non-adhesion. As a wine sealing material, it is very suitable, white and elegant, easy to buy, cheap, easy to install and unload, more suitable for wine sealed in wine cellar for later drinking, not suitable for display.

7, sealing wax.

Wax seals are common in sealed wine collections. This kind of wax is not a lighting wax, but a practical edible wax, which is more complicated. The operation method is to put the wax into a container and boil it into a liquid state, wrap a layer of soft material (soft paper is enough) around the bottle cap, and soak the bottle upside down in the wax liquid and take it out. After cooling, a layer of wax will form on the surface of the bottle cap.

Extended data:

For the storage environment of bottled liquor, we should choose a dry, clean, bright and ventilated place, and the relative humidity of the environment is about 70%. If the temperature is too high, the bottle cap of bottled liquor is prone to mildew, and the storage environment temperature of liquor should not exceed 30 degrees, and it should be away from fireworks.

The bottle seal of bottled liquor must be sealed to prevent the liquor in the bottle from leaking out. If it is white wine in a glass bottle, it must not be placed under strong light. Before storing liquor, the liquor to be stored should be detected in advance, and then the bottle cap should be tightened again. Because the bottle caps of some liquors are loose when they leave the factory, it is common for bottled liquors to deviate after several years, which is also an important thing to prevent bottled liquors from deviating.

Wine should be kept away from light. If placed in the sun for a long time, it will destroy the wine molecules in the bottle, change the chemical composition and seriously affect the taste, so it should be placed in the dark. Some people are used to putting wine in the basement, but they don't know that the basement is too humid, especially in the south. If it is stored for a long time, trademarks and seals are prone to mildew and rot, which seriously affects the appearance of wine.

Avoid putting it with irritating substances. Such as mothballs, perfumes, cosmetics, paints, etc. For example, in the era of planned economy, Maotai could not be bought with money. People finally get a bottle of Maotai that they can't bear to drink and put it in the cupboard and under the bed, but these places are prone to insects. At that time, people used to use mothballs to prevent insects, but the smell of mothballs was the easiest to enter Maotai wine bottles, and the taste of wine molecules would be polluted after contacting camphor, which seriously affected the taste.
