Engineered for PUR flat machines, whole-house cabinetry, and wall panel laminations, our materials provide superior scratch resistance, zero stress-whitening, and pristine flatness.
Global demand for premium residential and commercial spaces has triggered a major paradigm shift in substrate finishing. Standard paints, high-pressure laminates (HPL), and conventional PVC overlays are facing severe limitations regarding Environmental Health and Safety (EHS) mandates, VOC regulations, and manufacturing performance. Modern interior fabricators are switching to modified polyesters, specifically PETG (Polyethylene Terephthalate Glycol) and co-extruded GAG (PETG/APET/PETG) structures, to achieve premium high-gloss and soft-touch matte finishes.
These advanced films are optimized for high-speed continuous line operations using Reactive Polyurethane (PUR) adhesives. They offer unparalleled surface optical clarity, excellent scratch and impact resistance, and eliminate common manufacturing defects like orange-peel textures, edge chipping, and stress-whitening during structural post-forming.
A global leader in functional polymer film extrusion and surface hardening technology, delivering advanced surface solutions since 2005.
Established as a commercial entity in 2017 with roots extending back over two decades in precision coating and polymer surface curing, Ganzhou Zhongyou Film Material Co., Ltd. is a high-tech enterprise dedicated to functional polyester films. Our expertise spans basic polymer synthesis, complex multi-layer co-extrusion, chemical micro-coatings, and high-precision slitting.
Operating a massive 60,000 m² modern production facility, we maintain absolute control over every stage of manufacture. By running our extrusion lines within integrated cleanrooms, we minimize contaminants that could compromise visual quality during high-gloss lamination. We partner with custom furniture brands, panel manufacturers, and industrial laminate suppliers globally to provide reliable, high-yield surface materials.
Why modern volume manufacturers, OEMs, and project specifiers demand custom interior films that meet rigorous technical standards.
Industrial laminators run at speeds from 15 to 40 meters per minute. Materials must offer high thermal stability, consistent surface tension (minimum 38 dyne/cm), and predictable shrinkage parameters to prevent warping or delamination on PUR adhesive lines.
High-traffic surfaces like kitchen cabinets and reception counters require superior wear resistance. Our films feature specialized chemical surface curing, providing up to 2H pencil hardness, scratch resistance, and easy-clean properties.
Traditional PVC films can release plasticizers and chloride gases over time. Our PETG and GAG structures are highly stable, completely non-toxic, and release only water and carbon dioxide during thermal disposal, satisfying EU REACH and RoHS standards.
Developing premium functional films requires precise control over raw material properties. Ganzhou Zhongyou utilizes a specialized dry-blending system for PETG and APET resins, followed by a multi-manifold co-extrusion feedblock. This process yields a balanced PETG - APET - PETG (GAG) structure, optimizing material performance and economy.
Molten polymers are co-extruded through a high-precision flat T-die. The outer PETG layers provide excellent thermoforming properties, while the dense amorphous APET core provides structural rigidity and impact resistance.
Extruded films enter our Class 100k cleanroom facility for chemical nano-coating. This process deposits a micro-level layer of high-performance acrylic polymer, enhancing scratch resistance and surface touch.
The functional coating is cross-linked using industrial UV lamps. This molecular curing hardens the surface to up to 2H, creating a durable barrier against UV yellowing, domestic acids, and physical abrasion.

GAG (PETG-APET-PETG) film offers a balanced cost-to-performance profile. The pure PETG skin layers retain the chemical resistance, high surface gloss, and easy post-forming characteristics of PETG. The core is composed of APET (Amorphous Polyethylene Terephthalate), which adds mechanical stiffness, puncture resistance, and tensile strength. This reduces overall production costs while maintaining the surface finish and performance of solid PETG.
For optimal bonding on high-speed flat lamination lines, we pre-treat the reverse side of our PET/PETG films using corona discharge. This treatment modifies the surface structure, raising the surface energy to 38–42 dynes/cm. This allows the PUR hot melt to wet out completely across the film, preventing delamination along edges under changing temperature and humidity conditions.
Orange-peel textures usually occur when micro-particles on the substrate show through the film, or when the adhesive layer is uneven. Ganzhou Zhongyou addresses this by extruding films under strict cleanroom conditions, ensuring uniform thickness (within ±3%). When applied over high-density fiberboard (HDF) or calibrated particle boards with clean PUR adhesive lines, our films maintain an exceptionally flat, mirror-like finish.
