Vapor barrier aluminum foil
Vapor barrier aluminum foil have great high temperature resistance, moisture resistance, and barrier properties. Because of its good barrier properties, it can be effectively applied to food packaging that requires long-term storage. The aluminum foil rolling mill is equipped with advanced automatic thickness control system and shape automatic control system to realize accurate control of shape and thickness. Select high quality aluminum foil blank, strictly control the hydrogen content, nonmetal slag content and grain size to ensure the product quality from raw materials. Compared with other packaging materials, aluminum foil has low moisture permeability, good moisture resistance, and at the same time has the advantages of safety, convenience and long shelf life. Although the thickness of aluminum foil is reduced (less than 0.02mm), pinholes and as the thickness of the aluminum foil increases, its moisture-proof performance is still superior to plast...
