ABSTRACT:
A packaging tape for use in packaging or bundling comprises a tape-like substrate and a self-adhesive layer prepared from an aqueous mixture and coated to dry on at least one surface of the tape-like substrate, wherein the aqueous mixture contains water soluble adhesive as an anchoring ingredient to the tape-like substrate and rubber latex as a self-adhesive ingredient which are mixed with each other by the weight ratio of the water-soluble adhesive to the rubber latex. The packaging tape can provide a sufficient tightening effect on articles to be sealed, bundled, etc. as comparable with that of ordinary adhesive tapes and can be released from the articles quite smoothly without damaging or contaminating the surface thereof.
