perlalux®identity is a unique, patented system for an anticounterfeiting solution for blister films. during the production of these anticounterfeit films, visible or hidden, customerspecific security elements are directly applied in the film. the elements form an integral part of the film and can not be copied or removed without damage. perlalux®identity films offer the same characteristics in terms of product barrier and shelflife as those without security elements. moisture and oxygen permeation values are identical and the processing properties are unchanged. in terms of physical properties, protection and physiological harmlessness, these films comply with all the latest international guidelines, directives and standards for pharmaceutical packaging materials.
