| 摘要 |
<p>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) and a peelable protective polymer layers (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).</p> |
