Zusammenfassung:The present invention relates to a tamper-evident push- through packaging secured against fraudulent reuse comprising: - a polymer base web (1) comprising at least one pocket; - a multilayer lidding film (2) covering said pocket, said multilayer lidding film (2) comprising on its seal side a coextruded polymer film, said coextruded polymer film comprising a push-through polymer layer (3) sealed on the base web by a permanent seal and a peelable protective polymer layer (4), the polymers of both layers (3,4) being incompatible and in direct contact with each other, without interlayer, the adhesion between said push- through polymer layer (3) and said peelable protective polymer layer (4) being lower than the seal strength between said polymer base web (1) and said push-through polymer layer (3), wherein, in use, the push-trough layer leaves a seal seam (6), after removing the part of the push-trough layer (3) covering the pocket and wherein said protective layer (4) cannot be resealed by a heat sealing process on said seal seam (6).
