タイトルまたは説明

When sheet in coil form is rolled to below **0 microns, it is called foil. Aluminium foil can be as thin as five microns but normally bulk usage is seven microns upwards. The thicker gauges (**0 microns upwards) are used for industrial applications such as cable wrapping and air conditioner finstock. Thicker gauge packaging is mainly used for applications like pilfer-proof bottles and taggers (inner diaphragms of tin containers).
