Quality Assurance
Systematic examination of incoming raw materials and packaging substrates ensures that shipment lots conform to technical specifications before they enter the production environment. A goods-in inspection involves checking moisture levels, basis weight, caliper, and surface finish of paperboard rolls or pallets upon delivery. This verification process prevents defective material from causing machine down-time, tool damage, or product waste on the converting line.
It establishes the baseline of quality for all subsequent processing steps.
Testing Protocol
Structured sampling plans dictate how specimens are selected and tested from each arriving batch. Quality control staff measure the moisture content of the board using handheld meters or gravimetric methods to ensure it lies within the required forty-five to fifty-five percent relative humidity range. They also check for transit damage, such as crushed roll edges or torn moisture-barrier wrapping, which can ruin the feed on high-speed presses.
Material that fails to meet these threshold standards is flagged and quarantined to prevent accidental release to the warehouse.
Performance Outcome
Accurate recording of these entry-level measurements maintains the traceability of the supply chain. If a goods-in inspection is conducted consistently, it provides the data needed to file claims against the mill or supplier for sub-standard shipments. This documentation supports the continuous monitoring of supplier performance and protects the converter from absorbing the financial loss of defective paperboard.
