The European Manufacturers Paper Honeycomb Association (EMPHA) is the pan-European association for manufacturers of paper honeycomb core and paper honeycomb board products . It was founded in Amsterdam in 2010, and aims to represent the paper honeycomb industry.
Honeycomb is noted for its superior strength, rigidity and low aerial weight. Paper is a relatively low cost base material with low environmental impact. Paper honeycomb therefore is the most cost-effective core material available.
