The surface can print text or patterns, and the front and back have good printing performance. Aluminum foil is made of 99% electrolytes, calendering and other processing aluminum foil, non-toxic and tasteless, good electrical conductivity, light resistance, moisture resistance, etc. In modern packaging, almost all flexible composite packaging materials require high barriers or shading. All aluminum foil is used as a barrier material. This is because aluminum foil has a highly compact metallic crystal structure that is perfectly capable of blocking any gas.
