18 micron aluminium foil is a widely used thickness in the aluminum foil industry, offering an excellent balance between strength, flexibility, and barrier performance. It is manufactured from high-purity aluminum through advanced rolling processes, ensuring consistent thickness, smooth surface quality, and reliable performance.
With its superior moisture, light, oxygen, and odor barrier properties, 18 micron aluminum foil is ideal for applications that require enhanced protection and durability. Compared with thinner foils, it provides improved puncture resistance and formability, making it suitable for both manual and automated processing.
Description
