WIST offers recyclability/repulpability certification for corrugated products

Test wax alternatives for corrugated fiberboard

FBA logo
In partnership with IPS Testing Services, the Appleton, Wisconsin, independent testing laboratory, WIST provides repulpability/recyclability certification. WIST and IPS labs are approved by the Corrugated Packaging Alliance to perform certain tests of the Voluntary Standard for Repulping and Recycling Corrugated Fiberboard. The protocol is used to certify the repulpability and recyclability of wax alternatives for corrugated products that have been treated to improve performance in the presence of water and water vapor. Contact us for a quote or to discuss your project needs.
