High Gloss & Super Matte Functional PETG/GAG Films for Industrial PUR Hot-Melt Systems
Addressing the Global Shift Towards Thermoplastic Polyester Surfaces: PET, PETG, and GAG Co-Extrusion Tech.
In modern architectural design and furniture engineering, selecting surface materials involves balancing aesthetic properties with mechanical resilience and ecological impact. The modern decorative laminate market is undergoing a structural transition. Manufacturers are moving away from traditional chlorinated polymers (PVC) and thermosetting melamine papers toward high-performance, non-toxic, and highly recyclable thermoplastic polyesters. Specifically, PET (Polyethylene Terephthalate), PETG (Polyethylene Terephthalate Glycol-modified), and GAG co-extruded films have emerged as the benchmark materials for premium panel production.
As a leading ODM Chart Ki Decoration Manufacturer & Exporter, Ganzhou Zhongyou Film Material Co., Ltd. sits at the intersection of material science and precision manufacturing. The terminology "Chart Ki" refers to a systematic approach to cataloging, indexing, and executing custom architectural decoration profiles. This design cataloging system bridges aesthetic trends with technical requirements. Whether dealing with high-gloss finishes for cleanroom environments or soft-touch, super-matte films for high-end residential cabinetry, our decorative films are engineered to meet the demands of continuous PUR (Polyurethane Reactive) flat lamination, profile wrapping, and post-forming lines.
Information Gain Insight: Unlike standard PET films that run the risk of crystalline stress-whitening when folded, PETG incorporates a glycol modifier during polymerization. This prevents crystallization, yielding a polymer that is highly amorphous, highly impact-resistant, and chemically compatible with PUR hot-melt adhesives without the need for extensive corona pretreatments.
A Trusted Top 10 Enterprise in PET Film Innovation
Established with a deep heritage in the advanced coating and surface-hardening sectors, Ganzhou Zhongyou Film Material Co., Ltd. has developed specialized solutions in the coating, extrusion, and laminating industry over the past two decades. We focus on research, development, and mass-market distribution of high-performance functional films. By integrating raw material extrusion, precision slot-die coating, multi-layer co-extrusion laminating, and dust-free slitting into a unified production pipeline, we ensure that every batch of film complies with international quality standards.
Our facility serves as a major hub for global furniture brands, cabinet manufacturers, and architectural panel laminators. We customize film formulations for anti-fingerprint, scratch-resistant, and high-gloss requirements, allowing us to supply tailored solutions that align with local standards and technical demands.
Engineering Principles of PETG & GAG Laminations
GAG is a three-layer composite film produced through co-extrusion, comprising a core layer of APET (Amorphous PET) sandwiched between two skin layers of PETG. This design combines the cost-effectiveness and mechanical stiffness of APET with the excellent heat-sealing, chemical bondability, and processing properties of PETG.
To achieve high scratch resistance (up to 4H on the pencil hardness scale) and ultra-matte levels (Gloss < 3 GU at 60°), we utilize excimer curing technology. Short-wavelength UV radiation under an inert nitrogen atmosphere cures the top skin coat, producing a micro-folded structure that diffuses light and resists fingerprints.
Our films are back-treated with a primer layer designed to bond with Polyurethane Reactive (PUR) hot-melt systems. This prevents surface defects like orange peel, telegraphing, and adhesive failure under conditions of high humidity or temperature fluctuations.
Extrusion of virgin PETG polymers combined with specialized processing aids. Real-time control systems manage thickness tolerances across the width of the film (±1.5% variance limits).
Combining APET and PETG layers inside the co-extrusion feedblock. The temperature profile is maintained between 240°C and 270°C to secure interlayer adhesion without thermal degradation.
Applying functional topcoats in a Class 10,000 cleanroom environment. The coated film undergoes UV or EB curing, creating a cross-linked network that offers chemical resistance to household solvents and grease.
From Modern Residential Interior Architecture to Commercial Installations
High-gloss and super-matte PETG films provide a barrier against water vapor, standard household detergents, and grease staining. The post-forming capability of the film allows for seamless edge wraps, minimizing moisture ingress along structural board interfaces.
Soft-touch, low-gloss GAG films offer a premium tactile feel. Scratch resistance (2H-4H) ensures that everyday items like hangers, belts, or jewelry boxes do not leave micro-scratches on panel surfaces.
Our PET decorative films can be laminated onto MDF, particleboard, or mineral wool substrate materials. Flame retardancy features (such as Class 1 or Class A rating compatibility) make these films suitable for commercial wall linings.
With a non-porous structure and anti-microbial surface treatments, our PETG panels can be disinfected regularly, helping to maintain clean conditions in hospitals, clinics, and high-traffic retail spaces.
Ganzhou Zhongyou Film Material Co., Ltd. provides customized aesthetic materials across multiple residential spaces, including bedrooms, cloakrooms, kitchens, living rooms, and restaurants. By adjusting the formulations of our PETG and GAG decorative films, we maintain visual consistency throughout the home while providing specialized performance characteristics for different environments.

Addressing Common Issues in Panel Laminating & Material Sourcing
To achieve high-quality results, line tension should be managed to prevent elongation. Apply adhesive uniformly at rates between 60 to 90 g/m², depending on substrate porosity. The lamination rollers should be maintained within a temperature range of 50°C to 70°C to facilitate adhesive curing and polymer bonding. Additionally, the substrate core board must be sanded clean of dust particles to prevent optical flaws.
"Chart Ki" represents a unified design system mapping raw visual textures (wood grain, marble veining, metallic effects) to precise technical parameters like surface gloss, UV protection factors, and heat distortion points. This integration enables developers and exporters to source matching finishes across multiple substrate materials (MDF, mineral boards, particleboards) while maintaining consistent optical properties.
Our functional PETG films utilize a dual-curing surface treatment. The top coat remains partially flexible after extrusion, allowing the film to adapt to tight 3D radii and sharp angles (profile wrapping and post-forming) without stress fractures. A secondary chemical cross-linking step can be completed in-line or via natural aging, locking in scratch resistance (up to 4H pencil hardness) while retaining flexibility at the corners.
Yes, both PETG and GAG are halogen-free, chlorine-free, and do not contain toxic plasticizers. Unlike PVC, they do not release hydrochloric gases during combustion. Their composition allows for clean mechanical recycling, making them compatible with green building certifications such as LEED and BREEAM.
