Case Study: Newark Paperboard achieves stable processes and customer-quality deliverables with Northwest Analytics’ NWA Quality Analyst

Newark Paperboard Products Produces Customer Quality Deliverables with NWA Quality Analyst

Newark Paperboard, the Longview, WA plant of Newark Paperboard Products and the third-largest tube and core supplier in North America, needed to ensure critical tube performance (wall strength, crush resistance, dimensions, moisture, unit weight) and consistently deliver SPC-based quality reports to customers as required by their ISO 9001 registration. To address large process variation and provide reliable customer quality deliverables, they turned to Northwest Analytics and its NWA Quality Analyst software.

Northwest Analytics’ NWA Quality Analyst was used to import test data (via ODBC from Excel/Access and directly from compression testers), produce control charts and histograms for in-house use and customer reports, and automate filtering and calculated fields for easier floor-level use. The result: improved raw material performance, reduced waste, a stable process that consistently meets specifications, faster supplier feedback, and professional quality deliverables—outcomes Newark Paperboard attributes directly to Northwest Analytics’ solution.
