Inside Our Release Paper Factory — Coating Lines & QC Lab
Silicone coating, slitting, rewinding and release testing in Shanghai’s Songjiang Industrial Zone — the source behind every roll.
One Factory, Full Liner Supply Chain
Coating to packing under one roof.
Our Shanghai base in Songjiang Industrial Zone runs the complete liner production sequence: incoming base inspection, five-roller silicone coating, thermal curing, per-batch release testing, precision slitting and rewinding, then export packing.

The Six-Step Production Sequence
Same sequence, every roll, with per-batch testing.
Base Inspection
Gram weight, moisture, defects.
Silicone Coating
Five-roller line, controlled coat weight.
Curing
Thermal crosslink for stable release.
Property Testing
Release force & residual adhesion.
Slitting
Custom widths to your core specs.
Packing
Export-grade packing and coding.
Release Testing on Every Batch
Numbers before shipping — not after complaints.
Release Force Testing
Per-batch release force verified against your specified window (3-80 g/25mm, ±3g tolerance).
Residual Adhesion Testing
Residual adhesion checked per batch to confirm the silicone release layer protects your adhesive performance.
