Practical approach
Ask how samples were stored and whether the relevant commercial packaging was included in the evaluation.
A laboratory reference in a different container can support chemistry work while leaving a new retail closure unqualified.
Decision limits
Do not assume a liquid-performance report also proves packaging stability or transport suitability.

Compound Packaging: Test the Last Quarter of a Bottle

Packaging Compatibility for Private Label Ceramic Coatings
Review bottles, closures, labels and filling arrangements together before approving private label ceramic coating packaging.
Coating Sustainability Claims: Separate the Product from the Packaging
A packaging improvement does not automatically establish the environmental profile of the entire product or service. Keep the claim's boundary clear.
