These bags usually have a four-layer structure, are opaque, silver-white, with a reflective luster, and offer excellent barrier properties, heat-sealability, light-blocking, high and low temperature resistance, oil resistance, fragrance retention, non-toxicity, and odorlessness, as well as softness.
