Aluminum foil mylar bags are wrapped with layers of aluminum foil on the inside, which provides very good resistance to moisture and oxygen. This is very important for cannabis, which is susceptible to moisture and oxidation. For example, for cannabis’s dryness, color, smell and other aspects of protection, aluminum foil mylar bags have a very good guarantee.  Aluminum foil mylar bags adopt an opaque design, which can effectively protect the privacy and security of the items inside the bag.
