Medford, N.J.-based Polymer Solutions has recently introduced the new, all-plastic triple pocket Pro-Stack™ Modular Bottled Water Rack System. Available for immediate shipment, the triple pocket ProStack utilizes the same innovative design features as the well-received double pocket ProStack, which has been in use in major bottling operations for the past three years. Both the double and triple pocket models feature pockets that fully surround the bottles protecting them from impact and over-the-road bottle bounce.
