The buyer must connect gas delivery, package headspace, film barrier and seal quality to a measured residual-oxygen target rather than treating nitrogen as a simple machine option.
What the project must solve
Gas flow alone does not establish residual oxygen because headspace, product voids and purge position change displacement.
A low reading immediately after packing can still fail shelf life if barrier or seal integrity is inadequate.
Nitrogen consumption can increase sharply when purge time compensates for poor nozzle or bag geometry.
Buyer analysis
Write a measurable gas-pack specification
Define the test instrument, sampling location, measurement time after sealing and acceptable residual-oxygen range. Include package leak criteria and the final film structure.
Optimize displacement before increasing flow
Nozzle position, purge timing, product bed and pouch opening determine how efficiently air leaves. Trials should record both achieved residual oxygen and gas consumption per good pack.
Verify performance over the intended shelf period
Initial readings confirm the packaging cycle; later readings help evaluate seal and barrier performance. The machine supplier, film supplier and product owner should agree on the test plan.
