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