Integra aluminum foil sealing pockets have good barrier properties and are suitable for packaging of pharmaceuticals that are sensitive to moisture and oxygen and require ethylene oxide sterilization (EtO). The same product is used for sealing and aluminum foil, and the uncoated Tyvek seal is porous, which can shorten the sterilization time. After the package has been sterilized by Eto, the seal can be removed from the foil bag and the bag can be resealed. The foil bag is very easy to seal and open.
