Hopper Covers™ made from our Insul-Quilt™ insulation are an efficient, cost effective remedy to a drying problem all too familiar to plastic processors. The Hopper Cover™ will nullify the outside environmental effects on your precious dried resins while in your hopper. Processors who dry their resins are continually fighting high humidity, daily shop temperature changes, and unexpected breezes passing through their facility affecting their drying process. Processed resins that should be dry, but are not dry, make for rejected parts!!!

Insul-Vest manufactures a specific insulation custom designed for your hopper. This custom design allows for complete access to all hopper entries, exits, sight glasses and doors.
