Containerboard
Program Overview
The CTS Containerboard Program traces its origins to the 1969 Collaborative Reference Program (CRP) for Linerboard, originally established with the National Bureau of Standards (NBS, now the National Institute of Standards and Technology, (NIST)). Today, the program remains guided by industry needs and professional technical input. Linerboard, corrugating medium and corrugated board samples are taken from one lot, randomized, and sealed at one time for repeated distribution. Corrugated boxes are selected and randomized in a similar manner. Weekly and monthly testing delivers continuous measurement assessment, enabling participants to consistently monitor performance and take faster corrective action if necessary.
