Inspection Details

Roll / lot identification recorded

Enter the release liner roll number, lot number, supplier, and any internal material code.

Inspection stage

Select when the inspection is being performed.

Material specification or SOP referenced

Reference the approved specification, work instruction, or customer requirement used for acceptance.

Inspector name and date

Record who performed the inspection and when.

Roll Condition and Handling

Roll edges are intact and free of crush damage critical (required)

Verify there is no edge crush, gouging, or deformation that could trigger web breaks or tracking issues.

Yes No N/A

No telescoping, blocking, or roll deformation observed critical (required)

Check for telescoping, blocking, ovality, or other roll-shape defects that affect unwind stability.

Yes No N/A

Core condition acceptable critical (required)

Confirm the core is not crushed, split, loose, or out of round.

Yes No N/A

No visible contamination, moisture, or foreign material on roll critical (required)

Inspect the liner surface and roll packaging for dust, oil, water, adhesive transfer, or other contamination.

Yes No N/A

Photo evidence (optional)

Caliper and Web Uniformity

Caliper measured within specification critical (required)

Measure liner thickness at the required sampling points and compare against the approved specification.

Note (optional)

Caliper variation across web is acceptable critical (required)

Confirm thickness variation does not indicate coating build, caliper drift, or web non-uniformity that could affect processing.

Yes No N/A

No wrinkles, gauge bands, or web distortion observed

Inspect for wrinkles, bands, cockling, or distortion that may indicate caliper or winding issues.

Yes No N/A

Coating and Surface Defects

No coating skips, voids, streaks, or pinholes critical (required)

Check the release coating for missing areas, streaking, pinholes, or other visible coating defects.

Yes No N/A

Photo evidence (optional)

No silicone transfer, rub-off, or surface contamination critical (required)

Verify the release surface is stable and free from transfer, dusting, or contamination that could affect release value.

Yes No N/A

Photo evidence (optional)

No blisters, bubbles, gels, or coating lumps observed critical (required)

Inspect for raised defects, gels, bubbles, or lumps in the coating or substrate that may cause web breaks or print defects.

Yes No N/A

Surface appearance consistent across roll

Rate overall visual uniformity of the liner surface from poor to excellent.

Release Value and Performance

Release value test performed critical (required)

Confirm a release value or peel test was completed using the approved method when required by the specification.

Yes No N/A

Release value within acceptable range critical (required)

Record the measured release value and compare it to the approved target range for the product or process.

Note (optional)

No abnormal adhesion, sticking, or premature release observed critical (required)

Verify the liner does not stick excessively, release too easily, or show inconsistent release behavior that could cause delamination or process instability.

Yes No N/A

Disposition and Corrective Action

Disposition selected critical (required)

Choose the material disposition based on inspection results.

Non-conformance or defect summary

Summarize any observed deficiency, suspected cause, and affected roll location.

Photo evidence attached for defects

Attach photos of any coating defects, caliper-related damage, or roll condition issues.
