发明名称 Resealable closure and method of making same
摘要 A flexible package for a product includes a resealable closure for resealing one portion of the package to an opposing portion of the package. The resealable closure is formed by applying a layer of pressure-sensitive adhesive on the inner surface of at least one of the opposing portions of the package, and applying a layer of cohesive to the inner surface of both of the opposing portions so that the pressure-sensitive adhesive layer is covered by a layer of cohesive. The pressure-sensitive adhesive has a greater affinity for adhering to the cohesive than to the inner surface of the package. Accordingly, pressure-sensitive adhesive is detached from the inner surface of the package when the opposing portions are pulled apart, and the portions can be resealed by pressing the portions back together to cause the pressure-sensitive adhesive to adhere to the portion from which is was detached.
