Abstract

The present invention provides an adhesive formulation packaging article comprising an adhesive formulation and a packaging film encapsulating said formulation, the packaging film being heat-sealed around the adhesive formulation, wherein the heat-sealed portion of the packaging film comprises embossing The heat-seal portion and the flat heat-seal portion, and the embossed heat-seal portion and the flat heat-seal portion each form a pattern around the periphery of the adhesive formulation. The adhesive preparation packaging product of the present invention has no pinholes in the heat-sealed portion, and can maintain excellent airtightness and sterility.

Description

technical field [0001] The present invention relates to an adhesive preparation package. More specifically, the present invention relates to an adhesive formulation packaged article comprising an adhesive formulation encapsulated by a packaging film heat-sealed around the adhesive formulation. Background technique [0002] In recent years, in order to protect and heal human skin wounds, bedsores, burn ulcers, donor sites, etc., dressings with various functions have been developed. The dressings are individually wrapped and then sterilized to prevent bacterial infection of the skin. This packaging plays an important role in ensuring a high degree of sterility. [0003] As a means of administration to a living body, a method of percutaneous absorption of a drug through the skin has been developed, which involves adhering an adhesive preparation containing a drug to a living body. This drug-containing adhesive preparation includes a carrier made of plastic films such as poly...
