Patent attributes
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.
