Competitive Market Landscape
The air permeability and water permeability of the aluminum foil after compounding is more than one million times lower than that of the raw material. Usually, the diameter of the pinhole is about 0.05mm-0.3mm. Therefore, the relationship between the number of pinholes and the air permeability can be determined. The area of the pinhole is proportional to the square of the diameter, so a 0.03mm pinhole is 100 times worse than a 0.3mm pinhole. It can be said that adding aluminum foil and not adding aluminum foil are different grades of packaging. The difference in air permeability and water permeability is more than one million times. The shading properties of aluminum foil can also be described in a similar way. The above description is suitable for statistical significance. For specific packages, due to the uneven distribution of pinholes, for example, if a package of 10mm*10mm has a pinhole, its sealing effect can only be increased by 1000-10000 times.
