Yazoo Quality Control

From raw materials to finished products, we demand quality. Quality, reliability, and consistency are a way of life at Yazoo. All of our tubes are manufactured from 100% recycled paperboard, custom made to our specifications, from the best-in-class mills in North America. We hold all of our raw material suppliers to strict tolerances in order to produce a high quality consistent product for our customers.
     
The Yazoo quality control system is in effect for inspecting and testing all raw materials before and during processing. This system provides assurance that the material continues to meet the physical, chemical, functional, visual, and dimensional requirements needed for the customer. Listed below are the specific tests on raw materials and finished products. Detailed information on these tests and quality checks are contained in our "Quality Assurance Manual."

Tests Performed on Raw Materials in the Yazoo quality control process:

  • Basis Weight of Paperboard
  • Tensile Strength and Tear Resistance
  • Caliper (thickness of paper)
  • COBB Test (water absorptiveness)
  • Ring Crush (compression resistance)
  • Stiffness of Paperboard
  • Bursting Strength (mullen)

Yazoo Quality Control Testing Done on Finished Tubes and Cores:

  • Measuring Warpage
  • Delamination of Adhesive Bonds due to water immersion and high humidity
