Packaging Inspection

Packaging inspection covers the pack itself, material, seal and the code printed on it. It does not cover the product inside the pack, the label's content, or the pack's declared quantity, each of which has its own instrument in this programme.

ISO 9001 treats packaging as part of production control and traceability rather than as a topic of its own, which is why the requirements behind this inspection sit across several clauses rather than one dedicated section. Food and consumer-goods labelling standards then add specific date-marking and lot-identification duties on top.

The duty to check packaging sits partly in quality management standards and partly in food and consumer labelling law, and the two pull in slightly different directions on what a wrong code actually means.

The template prompts for a pass or fail on each item. It does not prompt for whether a Yes was checked against the actual code, or whether a partial seal result should have stopped the run, and those are the judgement calls that make the record defensible.

Packaging inspection findings are rarely about a missing check; the form is comprehensive. They are about whether an item marked Pass reflects what was actually verified.

A cold-cut line producing sliced ham passed its start-of-run packaging inspection: seal width, leak test and date code all recorded Pass, and the inspector signed off before the first pallet moved. The programme's stated frequency was start of run and set intervals, which on this site meant once at the top of the shift and once mid-shift.

Partway through the afternoon a customer complaint arrived for a pack with a visibly loose seal and a smell suggesting air ingress. The investigation found the sealing bar's temperature had drifted down through the shift as the jaw wore, a gradual change no single reading catches, and the mid-shift check happened to land before the drift became visible on that measurement. The packs made between the mid-shift check and the end of run had not been re-verified, and several hundred had already shipped. The corrective step was not more frequent seal testing at the same fixed clock times; it was tying the check to a shorter, fixed interval regardless of how stable the previous reading looked, so a gradual drift could not hide in the gap between two scheduled checks.

The form is the easy part. Keeping the code checked rather than merely present, catching drift between the scheduled intervals, and routing a knockout failure before the pallet ships is the work that actually slips.

KnowQuality

Holds the packaging inspection library against the run schedule, flags a knockout failure regardless of the calculated percent, and keeps the coding evidence trail together.

KnowLogistics

Carries case and pallet traceability forward into distribution, so a mixed-batch or coding flag raised here follows the pallet rather than stopping at the inspection record.

KnowComply

Tracks date and lot marking obligations against the jurisdictions a site ships into, and surfaces where a coding practice falls short of the applicable labelling rule.

Ella

Watches for a knockout item failing inside an otherwise passing percent, and raises it to the line lead rather than letting the arithmetic absorb it.

Knockout item

A check whose failure fails the whole record regardless of the overall percentage score.

Seal integrity

The combined result of seal width, strength and freedom from contamination; a pack can pass one measure and still fail another.

Date code

The printed use-by, best-before or production date, distinct from the batch code, which identifies the production lot rather than the calendar date.

Changeover carryover

Packaging materials from the previous run left on or near the line, the most common source of a mismatched code.

Traceability

The ability to link a finished pack back through its batch, materials and inspection record, which case and pallet labelling exists to preserve.
