What your packaging sample should prove
Last updated
Approving a sample means agreeing what was checked, what remains open and which version is approved.
Fit and removal
Use the actual product where practical. Check clearance around projecting features, product movement, contact points and whether each item can be removed without damaging the presentation.
Opening and closure
Check alignment, lid or tray clearance, closure feel and repeat operation. A closure feature does not by itself establish transport protection.
Appearance and artwork
Review print content, alignment, finish and physical colour references. An unprinted structural sample cannot approve print colour.
Packing and protection
Review the complete packing system and intended transport conditions. Record the test method and outcome where testing is required; a display sample is not a transport test.
The approval record
Identify the artwork and dieline versions, sample reference, review date, approved features and outstanding changes. Confirm whether another sample is needed before production.
Keep the checks tied to a version
For each observation, identify the product or agreed equivalent, the sample and artwork versions, the check performed, the result and any change requested. Recheck the affected feature after a revision.
Agree the colour reference and lighting or measurement method for printed work. If closure force, sealing or transport testing matters, specify the method and acceptance criteria for the order; do not assume a visual approval proves those results.
