Ready-to-Fill Disposable Liquids Totes

The Ready-to-Fill design offers all of the material handling advantages of a rigid Intermediate-Bulk-Container (IBC) with all the benefits of a disposable IBC. J Hill Container™ Ready-to-Fill totes are an ideal replacement for drums, returnable totes, bottle-in-cage IBCs, and other corrugated IBCs. Reduce your time and labor required for the filling, emptying, and handling of multiple containers with one Ready-to-Fill Tote replacing up to six drums and carrying up to 330 gallons of liquid.

As a replacement for returnable totes, Ready-to-Fill Totes eliminate the high cost of maintenance and return transportation. Versatile use with industrial chemicals (such as: adhesives, diesel exhaust fluid (DEF), water-based emulsions, heavy greases, lubricating oils, surfactants, paints, and coatings), and aseptic, white room or bulk commodities (such as: fruit juices, fruit purees, glycerin, propylene glycol, edible oils, fish oil, salad dressings, molasses, wine, liquid sweeteners and flavorings).
