Zusammenfassung:A pouch package, containing a volatile solution-impregnated patch, is made of a peelable barrier film. The pouch envelops an absorbent substrate saturated preferably with bug repellent fluid. A PSA (pressure sensitive adhesive) coated backing film is laminated to the absorbent substrate. The backing film has a connecting portion which is peelably sealed to the inside of the pouch. When the pouch is peeled open, the PSA coated backing film is exposed and placed against a target surface, such as a patch wearer's clothing. Finally, the side of the pouch facing the absorbent substrate is peeled off the backing film connecting portion to expose the absorbent substrate. A key to functionality of the pouch package is differential adhesion. First, the pouch barrier film must be peelable from itself, yet it must not adhere to the pressure sensitive adhesive on the backing film. A release paper may be used to cover the PSA when peeling the pouch open. Second, the pouch film must be peelable from the backing film connecting portion without disturbing the bond between the fastening surface and the target surface. Third, the backing film must be laminated to the absorbent substrate more strongly than the PSA adheres to the backing film, so that when the patch is removed from the target surface, the PSA stays with the patch. Un paquete de bolsa, que contiene un parche impregnado de solucion, volátil, se hace de una película de barrera desprendible. La bolsa envuelve un sustrato absorbente saturado de preferencia con fluido repelente a cualquier tipo de insecto. Una película de respaldo recubierta de ASP (adhesivo sensible a la presion) se lamina al sustrato absorbente. La película de respaldo tiene una porcion conectora que se sella desprendiblemente al lado interior de la bolsa. Cuando la bolsa se desprende para abrir, se expone la película de respaldo recubierta de ASP y se coloca contra una superficie objetivo, tal como una parche de la ropa del usuario. Finalmente, el lado de la bolsa que da hacia el sustrato absorbente se desprende de la porcion conectora de la película de respaldo para exponer el sustrato absorbente. Una clave para la funcionalidad de este paquete de bolsa es la adhesion diferencial. Primera, la película de barrera de bolsa debe ser desprendible por si misma, todavía esta no debe adherirse al adhesivo sensible a la presion sobre la película de respaldo. Se puede utilizar un papel de desprendimiento para cubrir el ASP cuando la bolsa se desprenda p
