Champion Box Company, Inc. of Cedaredge, Colorado was founded in April of 1997.  Champion designs and manufactures a complete line of portfolio cases, presentation folios, and storage boxes for protection, storage, transportation or presentation of your watercolors, oil paintings, photographs, etchings, documents, or other valued treasures. Its primary business is working with corrugated plastic to produce storage containers of all types and colors. Champion is the producer of the popular Artmate™ line of wet painting carriers or totes that Utrecht carries.

The Artmate™ artist containers are made from corrugated plastic sheeting. Chemically, the sheets are inert (acid free), with a neutral pH factor. The extruded twinwall sheets are made from high impact polypropylene copolymer. Most oil, solvents and water have no effect on the material, allowing it to perform under adverse conditions. The opaque sheets have virtually no out-gassing and keep harmful sunlight (and UV rays) away from your stored artwork. This makes for a near perfect archival material that is lightweight, durable, and inexpensive.
