본 발명은 휘발성 용액 불투과성 패치를 수납하는 봉지 패키지를 박리가능한 차단 벽으로 만든 것이다. 봉지는 해충 방지 유체로 바람직하게 포화된 흡입 기질을 밀봉한다. PSA(압력에 민감한 점착제)를 피막시킨 배킹 막이 흡입 기질에 박막화된다. 배킹 막은 봉지 내측에 박리가능하게 밀봉되어 있는 연결부를 가진다. 봉지가박리되어 개봉되는 때, PSA로 피막처리된 배킹 막이 노출되고 패치 착용자의 의복과 같은 표적 표면에 대향하여 배치된다. 끝으로, 흡입 기재와 대면하는 봉지의 측부는 배킹 막 연결부를 박리하여 흡입 기질을 박리한다. 봉지 패키지 기능의 핵심은 차별성 접착이다. 첫째로 봉지 차단막은 그 자체가 박리가능하여야만 하므로 배킹 막상의 압력에 민감한 점착제에 접착되어서는 안된다. 둘째로, 봉지막은 고정 표면과 표적 표면 사이에 접합부를 부여할 필요 없이도 배킹 막 연결부로부터 박리가능해야 한다. 셋째로, 배킹 막은 PSA가 배킹 막에 접착되는 것보다 더 강하게 흡입 기질에 박막화되어 패치가 표적 표면으로부터 분리되는 때, PSA가 패치에 남아있게 한다. 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.
