Representative Sampling per Batch

Multiple samples are randomly selected from each completed production batch to ensure comprehensive representation, covering products across different production lots and spatial positions.

Standard Environment Conditioning

Surface impurities are thoroughly removed, and the samples are conditioned in a standard testing environment (temperature: 23±2°C, relative humidity: 50±5%) for 24 hours. This standardizes the physical state of the film to ensure maximum testing accuracy.

Core Performance Testing

Utilizing professional laboratory instruments, we execute a comprehensive suite of tests on critical performance metrics. Our core testing matrix includes: Weather Resistance Testing – Evaluation of long-term aging and UV stability. Adhesion & Adhesive Residue Analysis – Verification of bonding strength and zero-residue peeling. Tensile Performance Testing – Measurement of tensile strength and elongation at break. Gauge Uniformity Inspection – Continuous monitoring of film thickness consistency and flatness. Any non-conforming products are strictly prohibited from entering the warehouse, guaranteeing that every single batch dispatched to the market meets our stringent quality benchmarks.

Quality Traceability & Archiving

All inspection and testing records are meticulously archived to achieve full product quality traceability. In the event of any anomaly, this system enables us to rapidly pinpoint the root cause and implement corrective actions immediately.
