    • A temporary adhesive band provides a releasable sealing structure and a tearing structure in a plastic bag. The band can be coextruded with one or more panels of the bag and can be made from a polymer blend. It can have a relatively thick tear section that defines a tear line at a zone of weakness in the bag so that a closed end of the bag can be easily removed. The band also can have a releasable sealing section that remains attached to the bag after the closed end of the bag has been removed by tearing the bag along the tear line so that the bag can be resealed once it has been opened. The releasable sealing section of the temporary adhesive band is preferably made from a coextruded material with tacky properties so that no additional adhesive is required for resealing the bag.
    • 临时粘合带在塑料袋中提供可释放的密封结构和撕裂结构。 带可以与袋的一个或多个面板共挤出并且可以由聚合物共混物制成。 它可以具有相对较厚的撕裂部分,其在袋的弱点区域限定撕裂线,使得袋的封闭端可以容易地移除。 该带还可以具有一个可释放的密封部分,其在通过沿着撕裂线撕开袋子已经去除袋子的封闭端部之后仍然附着到袋子上,使得袋子一旦打开就可以被再密封。 临时粘合带的可释放密封部分优选由具有粘性的共挤出材料制成,使得不需要额外的粘合剂来重新密封袋。
