Abstract
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 ().
