AICC and FBA have jointly developed this brochure to be a simple, non-technical document to assist sales managers, sales representatives, customer service representatives and others in understanding the relationships between box compression strength, corrugated board edge crush test (ECT) and burst strength (Mullen) so the box maker and customer can determine the optimum solution to the customer needs.

This brochure is designed to be used by box plant production, structural designers, salespeople and general managers to help them understand the factors affecting ECT, box compression and retained compression, in the box plant. It also helps explain why it is important to know the details about customers’ products and distribution systems, and how ECT board combinations can best meet customer needs.
