The duties of a packaging sales professional focus on the effort to sell packaging materials to a customer or to get repeat orders from existing clients. Your responsibilities in this career vary depending on your sales role and the type of product that you sell. For example, you may sell industrial packaging, food packages, or packaging solutions for e-commerce. Sales team roles might include sales representative, account manager, sales director, and customer service rep. Your team may be responsible for sales efforts in a geographic area or “district.”
