The line is fitted with an inline thickness gauge that holds the cast film precisely to its target thickness and flatness. Every roll is then re-inspected manually offline.

Every roll and every metre of PVB film completes a full-width defect scan on the line, and is then re-inspected manually — a high standard, strictly applied.

Every roll is tested by our laboratory specialists and released only once it passes. Test data and retained samples are kept for the long term to support traceability.

Quality assurance
Your trust is what drives us. Our quality control system covers incoming material, in-process production and finished goods, so that every roll of PVB interlayer film is consistent in safety, weather resistance and optical performance.
