Abstract

Packaging for the sterile storage and transport of objects for medical, pharmaceutical or cosmetic applications and a packaging process are provided. The packaging includes at least one bag made of a first and a second web, bonded to one another, a feature thereof being that the first web consists of a selectively permeable nonwoven fabric and that the second web consists of a laminated film with at least three layers, where the first layer is a polymer film arranged on the external side of the bag, the second layer is a lamination adhesive and the third layer is a polymer film arranged on the internal side of the bag. At least one of the layers of the second web includes one or more pigments. In an 8-bit greyscale image, the seal seam, imaged in transmitted light and contrast-standardized, is depicted within a greyscale value range of 50-200.
