Roberts PolyPro Inc. offers a single-station multipack bottle handle applicator. The applicator applies high-density polyethylene carrying handles to 4-, 6-, 12- and 24-unit cases. A single machine with change parts will apply two-, three-, four- and six-pack carrier handles. Machines can be ordered automatic or semi-automatic. The unit is vendor neutral in terms of handles and the HDPE handles require less plastic than injection molded handles, the company says.
