East Alton, IL– May 19, 2004 – Olin-Winchester Ammunition has awarded Unimark Plastics 2003 Supplier of the Year. Olin-Winchester is the industry leader in center fire, rim fire, and shotgun ammunition and carries the most well known brand name in the world. Each supplier was placed into one of three categories: components, packaging, or raw materials and an award is given out for each category. Performance is then broken down into quality, price, delivery, and service and served as the basis for the overall Supplier of the Year award. This is a repeat award in the Unimark/Winchester relationship. This award is doubly satisfying this year, as it is coupled with a Category Award in Components as well. Unimark is proud to be involved in a strong and growing relationship with an industry leader like Olin-Winchester Ammunition. These awards are the result of a 12-year relationship between the two companies.
