A low-cost, multi-function adhesive wireless communications and transducer platform with a form factor that unobtrusively integrates one or more transducers and one or more wireless communication devices in an adhesive product system. In an aspect, the adhesive product system integrates transducer and wireless communication components within a flexible adhesive structure in a way that not only provides a cost-effective platform for interconnecting, optimizing, and protecting the constituent components but also maintains the flexibility needed to function as an adhesive product that can be deployed seamlessly and unobtrusively into various applications and workflows, including sensing, notification, security, and object tracking applications, and asset management workflows such as manufacturing, storage, shipping, delivery, and other logistics associated with moving products and other physical objects.

The invention is directed to a packaging film (2) comprising: a top layer (4) with at least one aperture (4.1); a bottom layer (8) adhered to the top layer (4); a tear layer (6) adhered to the bottom layer (8) and extending along the at least one aperture (4.1) so that upon traction on the tear layer, said layer tears the bottom layer (8) through the aperture(s) (4.1). The tear layer (6) extends beyond the at least one aperture (4.1), between the top layer (4) and the bottom layer (8), preferably longitudinally in two opposite directions. The invention also relates to a condom wrapping with such a film and to the manufacturing method for such a film.
