Disadvantages of bottled wine

Wine is a good taste beverage with high nutritional value and health care. It is now known that wine contains approximately 600 components that are beneficial to humans and its nutritional value is fully recognized. The packaging of wine is mostly based on glass bottles. The packaging of glass bottles not only provides excellent shelf life and fragrance, but also adds a variety of colors, which echoes and complements the color of the wine itself. Therefore, glass containers are considered to be the most popular for wine packaging. Best choice.

The structure of the metal lid seal for wine is generally the top seal in the cap and the sealed plug in the bottle mouth. The seal gasket seals against the squeezing deformation of the seal gasket by the top of the bottle mouth; the internal plug seals by the interference fit of its outer diameter and the inner diameter of the bottle mouth, and achieves isolation of the beverage from the outside world. The outer screw cap is tightened with a metal screw cap and the seal is completed with a heat shrink film. From the point of view of the production process, the inner stopper cap process is simple, the cost is low, and the tightness of re-tightening changes little, so it is widely used in wine packaging. From the perspective of its sealing principle, its sealing performance is not related to the final tightening torque of the cap. The actual tightening torque required for the actual production of the cap only prevents the accidental loosening of the cap, but this kind of contact fit is difficult to avoid effectively. Oxygen infiltration during preservation. In spite of this, most manufacturers judge whether the finished product sealability is just to check whether the product has leakage or not. The method is to vacuum the outside of the bottle and keep it for a certain period of time to see if the liquid leaks out to judge the tightness of the package, but for oxygen Infiltration problems are ignored by manufacturers.

It is generally believed that the oxygen permeability of the glass bottle is zero, and the filling product is qualified as long as no liquid leakage occurs, and the oxygen penetration at the later stage is completely negligible. In fact, this is not the case. Experiments have shown that the amount of oxygen delivered by the bottle mouth is much larger than people think. Taking the example of the finished glass bottle encapsulated in an aluminum bottle cap as an example, in the standard laboratory environment, the test is performed using the method of ASTM D1307 (measurement of oxygen permeability of the packaging container - Coulomb method), and the obtained oxygen permeability and beverage filling are obtained. The oxygen permeability of commonly used PET plastic bottles (without coating) is as follows:

In the air (ml/pak.day) in pure oxygen (ml/pak.day)

Glass bottle (aluminum bottle cap) 3.115.3

PET plastic bottle (without coating) 0.31.5



From the above data, it can be seen that the oxygen permeability of the glass bottle (aluminum cap sealing) is much greater than the oxygen permeability of the PET plastic bottle. Obviously, the oxygen penetration of the glass bottle is through the bottle cap, and the amount of permeation cannot be ignored. , to attract the attention of manufacturers. Whether the oxygen permeability of the wine seal is appropriate is an important indicator for the manufacturer to ensure the taste, nutrient content and shelf life of the wine.

For a wine packaging container, the bottle body and the bottle cap are not integrated, and even if the bottle body and the bottle cap have high barrier properties, the overall barrier property of the packaged product cannot be cut off by itself. Therefore, special equipment must be used for standardization. Testing to achieve accurate control of the oxygen throughput of wine packaged products.
