    Abstract: Adjoining strata of pressure-sensitive adhesive are transferred to a package substrate. The two outermost adhesive strata have different adhesion to the substrate. The adhesive strata are used as a reclosable fastener and are intermixed in the course of reclosing and reopening the package, the action being such as to advantageously compensate for contamination occurring at the reseal interface while maintaining the status quo at the permanent interface.

    Abstract translation: 相邻的压敏粘合剂层转移到封装衬底。 两个最外层的粘合剂层对基材具有不同的粘合性。 粘合剂层用作可重新闭合的紧固件,并且在重新封闭和重新打开包装的过程中混合,其作用是有利地补偿在重新密封界面处发生的污染物,同时保持在永久界面处的状态。
