Main performance indexes of aluminum foil materials
Thickness is one of the most basic and important physics of aluminum foil. The thickness of aluminum foil has a certain relationship with its barrier property. With the increase of aluminum foil thickness, its permeability to oxygen, water vapor, light and so on gradually decreases, correspondingly, its barrier performance is higher
Moisture permeability refers to the water vapor permeability of aluminum foil under certain conditions, which reflects the deterioration of moisture resistance of aluminum foil to a certain extent.
The existence of pinholes will seriously affect the barrier performance of aluminum foil. For example, in the steaming packaging bag with LV foil as the intermediate layer material, the existence of a large number of pinholes is easy to penetrate oxygen, water vapor and light, which will have adverse effects on the quality of packaged food, and even cause food spoilage.
