Aluminum foil bags typically refer to aluminum-plastic composite packaging bags, which are suitable for moisture-proof, light-proof, and vacuum packaging of large precision machinery and equipment, chemical raw materials, and pharmaceutical intermediates. These bags usually feature a four-layer structure, are opaque, silver-white, and have a reflective luster, offering excellent barrier properties, heat-sealability, light-blockage, high and low-temperature resistance, oil resistance, fragrance retention, and are non-toxic and odorless, with good softness. Our company can customize aluminum foil bags of different specifications and styles according to customer requirements. Please call or send samples for negotiation!
