A full polishing range.
From cutting and one-step correction to final finishing.
Classify private-label coating changes by their effect on the product, package, instructions and evidence before deciding what to revalidate.
Updated · NANOLAB Knowledge

A private-label change can be cosmetic, technical or both. Renaming a product, changing its closure and revising its formulation should not pass through the same review merely because each request arrives as an artwork update.
Record the current and proposed versions, reason, affected SKUs and intended start date. Identify linked components: a new dispenser may change dose instructions, while a new claim may require additional evidence without changing the formulation.
| Area | Review question |
|---|---|
| Performance | Could application or service behaviour change? |
| Packaging | Could containment or dispensing change? |
| Documentation | Do instructions, labels or safety documents need revision? |
| Evidence | Does existing support still cover the revised product or claim? |
A corrected spelling error may need only artwork review. A changed product-contact component may require compatibility work. Do not use a minor-change label to avoid reviewing a material effect, or require a complete product programme for every punctuation correction.
Approve the affected items together and record the first production or shipment using them. Retain superseded versions for traceability. For example, a new closure with revised dosing should not ship while the carton still describes the old dispenser. The change record should make that dependency visible before stock enters distribution.
Discuss your private-label coating project. For application and care, use the current instructions for the exact product.
