TEAR-PROOF PACKAGING COMPOSITE FILM AND PACKAGING

摘要

The packaging composite film (1) has an outer side (2) and an inner side (3). Said film further comprises a liner (5) facing the outer side (2), an inner layer (10) facing the inner side (3) and comprising a lower puncture and tear resistance than the liner (5), and an intermediate layer (6) soluble in liquid and disposed between the liner (5) and the inner layer (10). Liquid transport openings (12) are provided in order to transport liquid from the outer side (2) to the intermediate layer (6) soluble in liquid, completely penetrating the liner (5) and extending in the direction of the inner side (3) at least to the intermediate layer (6), without entering the inner layer (10). The packaging film (1) can be used for implementing a child-proof but nevertheless easily opened, and thus senior-friendly, packaging.
