Colorado Container’s quality lab is equipped to perform many standard quality tests, including ring crush, edge crush and pin adhesion, as well as Mullen bursting test, caliper and cortal depth tests. Testing equipment is calibrated by a registered, independent third party to assure adherence to TAPPI and ASTM standards. The company’s procedures, from design through manufacturing and shipping, are documented, reviewed and updated regularly. Colorado Container utilizes statistical process controls in many of its processes, including starch viscosity, print registration and compression tests.
