The invention discloses a woundplast aluminum foil composite packaging bag, which comprises a woundplast and a packaging bag outside the woundplast, and is characterized in that the packaging bag comprises a compound bag consisting of an inner plastic film layer, an aluminium foil layer and an outer package layer or a compound bag consisting of an inner plastic film layer and an outer plastic film layer. The packaging bag is a compound bag consisting of an outer package layer, a middle aluminium foil layer and an inner plastic film layer or consisting of an inner plastic film layer and an outer plastic film layer; moreover, because the packaging bag comprises the aluminium foil layer, the woundplast aluminum foil composite packaging bag has the advantages that: firstly, the woundplast is not affected by rain and water logging; secondly, the packaging bag has high moisture resistance and wetting resistance and good mould proof effect; thirdly, the packaging bag is abrasion-proof and nonperishable; fourthly, the packaging bag has good performance of preventing the intrusion of dirt; fifthly, the packaging bag has high intensity and an attractive appearance. When packed with a disinfectant, the woundplast aluminum foil composite packaging bag overcomes the defect of the volatilization of liquid in disinfectant, and ensures the product quality and medical treatment effect; meanwhile, by combining with the plastic film layer, the woundplast aluminum foil composite packaging bag has good adhesive property, and can be effectively sealed.
