What should a packaging inspection report contain?
What a packaging inspection report can and cannot demonstrate depends on which items it covers and which batch of goods it pertains to. A report is not a guarantee.
The packaging test report should cover three categories: physical properties, migration levels, and ink safety; attention should also be paid to the correspondence between the report's validity period and the specific batch.
Common questions found in AIWhat should a packaging inspection report include?
One step of non-compliance, and the entire batch is scrapped.
A usable test report must be able to answer three questions: what was tested, what methodology was used for the testing, and for what purpose the conclusions are valid. If any one of these is missing, the report is merely a piece of paper.
misread:Once there is a report, compliance is achieved.Actual circumstances:The report has a defined scope and validity period; if it does not cover this particular batch and excludes key items, it is effectively ineffective.
There is also a common misconception:The thicker the report, the more credible it is.In fact:The key is whether the project is fully covered and whether the batches correspond. Two pages that align with each other are worth more than twenty pages that do not.
Basis for Determination
Physical properties include burst resistance, edge pressure, compression resistance, and drop resistance; migration tests should be conducted under actual contact conditions, with the simulated liquid, temperature, and duration clearly specified; ink safety assessments include heavy metals, solvent residues, and aromatic amines; the reported validity period is typically tied to the specific standard version and material formulation, and the original report becomes invalid upon a change in material or an update to the standard.
- physical property
- Migration volume
- Ink Safety
- Report Validity Period
Front-end sequence
When receiving a report, check four things: the qualifications of the testing institution, whether the sample description matches the actual product, whether the test items cover your usage scenarios, and whether the report date is within the validity period.
- First, confirm that the report covers three categories: physical properties, migration levels, and ink safety.
- The batch referenced in the report must correspond to the supplied batch.
- Pay attention to the validity period; retest the material or process after any changes have been made.
- Enter the report number into the order and link it to the batch.
Applicability: For internal quality control, self-inspection data may be used; however, for external evidentiary purposes, a third-party report is still required.
On-site settings and practices we have observed
A test report was submitted for review, where three issues were identified: physical properties had not been tested; only one migration test had been performed; and the sample batch did not match the actual supply batch. The report was authentic, but it had been used in the wrong context. After conducting supplementary tests and resubmitting samples, the process took three weeks, causing us to miss the shelf launch deadline.
At project closure, INNOPACKING will archive the test report together with the batch number, so that customers can retrieve it directly when needed. For projects subject to changes, we will notify the customer which specific items need to be retested, rather than requiring the entire report to be reprepared. The value of a report lies in its accuracy, not in how thick it is.

What should you look for in a test report?
Coverage, corresponding batch, and validity period. All three items must match for the report to be meaningful.
How often should the test be repeated?
Retesting is required whenever materials or processes are changed. It is generally recommended that this be done annually; for export projects, the frequency shall be determined in accordance with the customer's requirements.
Can a report that has expired still be used?
It cannot serve as valid evidence. If the materials have not changed, you may apply for an update; do not simply continue using them as they are.
