A Trusted Top 10 Force in PET & Functional Sheet Innovation
Established in 2017, Ganzhou Zhongyou Film Material Co., Ltd. has been a pioneering force in the plastic coating, stabilization, and surface-hardening industry for over two decades. As a professional, technology-driven PET and PVC film manufacturer, we focus heavily on the research, development, and large-scale manufacturing of high-performance functional films and transparent color plastic sheets.
Through more than 8 years of intensive technical accumulation, we have established a highly complex and reliable production workflow. This encompasses direct co-extrusion, precision micro-gravure coating, multi-layer stabilization laminating, and dust-free high-accuracy slitting, ensuring flawless quality control and unmatched optical performance across all custom sheet and film products.
Precision-engineered configurations optimized for high-volume global distribution.
In modern industrial manufacturing and high-end interior architecture, transparent color plastic sheets have evolved beyond simple aesthetic materials. They are critical substrates engineered to offer strict optical clarity, environmental stability, and mechanical strength. This whitepaper analyzes the polymer developments of Polyethylene Terephthalate Glycol (PETG), Polyvinyl Chloride (PVC), and co-extruded GAG structures, outlining how they address complex surface-lamination and structural engineering demands.
Choosing the correct polymer substrate dictates lamination quality, processing yields, and long-term durability. Below is a comparative breakdown of key material properties:
| Material Structure | Optical Transmittance (%) | Impact Strength (kJ/m²) | Chemical Resistance | Tensile Modulus (MPa) |
|---|---|---|---|---|
| PETG (Glycol-Modified PET) | > 90% | 12 - 15 (No Break) | High (Resists acids, bases, alcohols) | 2,100 - 2,400 |
| GAG (Co-extruded PETG/APET/PETG) | > 89% | 10 - 13 | Medium-High | 2,300 - 2,600 |
| High-Grade PVC Film / Sheet | > 85% (Rigid) | 6 - 10 | Good (Vulnerable to ketones) | 2,800 - 3,200 |
Each material fills a specific niche in B2B supply chains:
The global transparent color plastic sheet industry is undergoing a significant transition driven by regulatory pressures, ESG targets, and consumer demand. The primary technological shifts include:
China is the global leader in functional plastic sheet extrusion due to specialized supply chain integration. Factories like Ganzhou Zhongyou lead this space through several key operational advantages:
Providing high-precision surface finish profiles across diverse interior environments.
For industrial furniture and panel processors, the performance of decorative films on PUR (Polyurethane Reactive) flat paste machines is critical. Film surface tension, back-side priming, and dimensional stability determine the efficiency of the lamination process.
Our GAG and PETG films are treated to achieve surface energy levels above 38 dyne/cm. This high surface energy facilitates instant wet-out and creates a strong bond with moisture-curing polyurethane adhesives. By optimizing tension profile controls during extrusion, we prevent the film from stretching or shrinking under tension. This consistency helps prevent edge-curling and delamination during high-speed lamination.
To successfully integrate materials into global supply chains, products must meet strict regulatory and quality requirements. As a major supplier, Ganzhou Zhongyou ensures compliance with international quality standards:
All transparent colored plastics and functional films undergo strict testing for REACH, RoHS, and phthalate levels, ensuring safety for indoor environments.
Formulated with premium UV stabilizers (HALS), our sheets and films resist yellowing, gloss loss, and brittleness under solar UV exposure.
Using spectrophotometer-based color matching, we maintain consistent color values across production runs (Delta E < 0.5), meeting strict corporate design standards.
Engineered for stability and high-performance lamination across diverse structural applications.

Detailed technical answers addressing common procurement and processing concerns.
PETG is modified with cyclohexanedimethanol (CHDM) to prevent crystallization, providing high clarity, impact resistance, and ease of thermoforming. APET (Amorphous PET) is more rigid and cost-efficient but can crystallize and become brittle when heated. GAG is a three-layer co-extruded sheet with APET in the middle and PETG on the outer layers. This structure combines the surface bondability and toughness of PETG with the cost efficiency of APET.
For most reactive polyurethane hot melts (PUR), we recommend keeping the application roller temperature between 120°C and 140°C. The exact pressure and speed settings depend on your line configuration, but maintaining web tension under 150 N/m helps prevent stretching and structural distortion.
We combine highly soluble organic dyes with high-clarity optical resin bases during the co-extrusion feed process. This method colors the plastic sheet while preserving high light transmittance (typically over 80% depending on the color density) without causing cloudy patches or pinholes.
Yes, all our film and sheet formulas are free from heavy metals, plasticizers like orthophthalates, and VOCs. Our products comply with REACH and RoHS standards, making them suitable for commercial, residential, and healthcare interiors.
We apply a PE protective film (ranging from 50 to 80 microns thick) to either one or both sides of the sheet. This protective film has controlled adhesion (40-100 g/25mm) so it peels off cleanly without leaving glue residue behind after lamination or installation.
