Explore our industrial-grade PET, PETG, and GAG decorative materials optimized for flat paste machines, vacuum pressing, and heavy-duty lamination setups.
Established in 2017, Ganzhou Zhongyou Film Material Co., Ltd. has established itself as an authoritative leader in the coating, extrusion, and hardening industry, building upon over two decades of technical innovation. As a premier industrial supplier, we specialize in high-performance functional films and custom rigid thermoplastic sheets designed for demanding structural and aesthetic deployments.
Our production system leverages an end-to-end processing topology—ranging from raw polyester crystallization, polymer blending, and multi-layer co-extrusion to high-precision surface coating and slitting. This allows us to manufacture custom 1mm White PET Sheets with unmatched gauge consistency, strict dimensional tolerance, and advanced surface functionalization like anti-scratch, anti-UV, and anti-static finishes.
A comprehensive examination of the mechanical, thermal, and optical properties of custom 1mm rigid white polyester sheets.
Polyester sheets (Polyethylene Terephthalate) engineered at a 1mm gauge typically span three major technical classes depending on processing additives and molecular alignment: APET (Amorphous PET), PETG (Glycol-Modified PET), and GAG (a co-extruded composite sandwich of APET and PETG layers).
For custom 1mm white PET sheets, specialized titanium dioxide (TiO2) masterbatches are infused during the melt extrusion process. This yields an opaque white barrier with high density and excellent light-blocking capabilities. The inclusion of glycol modifiers in PETG configurations prevents the crystallization problems typical of raw PET, allowing for superior thermoforming behavior without stress whitening or cracking. In contrast, GAG configurations offer the raw surface hardness of APET coupled with the ease of thermoforming and weldability inherent to PETG.
| Technical Parameter | APET Sheet (1.0mm) | PETG Sheet (1.0mm) | GAG Sheet (1.0mm) |
|---|---|---|---|
| Specific Density (g/cm³) | 1.33 – 1.35 | 1.27 – 1.30 | 1.30 – 1.33 |
| Tensile Strength at Yield (MPa) | ≥ 55 | ≥ 48 | ≥ 52 |
| Light Transmission (%) | Opaque White (< 0.5%) | Opaque White (< 0.5%) | Opaque White (< 0.5%) |
| Thermoforming Temp Range (°C) | 120 – 145 (Requires drying) | 110 – 135 (No pre-dry required) | 115 – 140 |
| Surface Hardness (Pencil) | 2H | HB - H | H - 2H |
| Izod Impact Strength (J/m) | 50 – 70 | 80 – 110 | 70 – 95 |
The opacity and brightness indices of our white PET sheets are controlled through custom-formulated rutile titanium dioxide masterbatches. Rutile TiO₂ possesses a refractive index of approximately 2.73, which is significantly higher than that of standard polymers (typically 1.5 - 1.6). This refractive mismatch is the primary engine behind light scattering: photons entering the 1mm sheet are repeatedly bent and reflected, rendering the sheet completely opaque even at thin gauges. We control the dispersion down to sub-micron particle sizes to eliminate streaks, maintaining a high CIE Whiteness Index (typically >85) and stabilizing yellowing metrics (ΔYI < 1.5 after accelerated aging tests).
How Ganzhou Zhongyou leverages state-of-the-art dual-screw extrusion and multi-layer feedblock configuration to build zero-defect white sheets.
Utilizing high-end multi-manifold dies and feedblock selectors, we control thickness distribution at the micron level. Our feedblocks enable structural cross-sections like A/B/A and A/B/C configurations, allowing users to combine outer functional skins (e.g., highly glossed PETG) with structurally rigid core centers.
Our 3-roll calendering stack maintains precise control over the surface finish, ensuring perfect planar flatness. Calendering roll temperatures are dynamically regulated via pressurized hot water loops to prevent internal material stress and ensure high surface energy (exceeding 38 dyne/cm for optimal adhesive bonding).
Functional liquid coatings (anti-scratch, anti-fingerprint, and soft-touch matte lacquers) are applied within Class 100,000 dust-free cleanrooms. Cured via inline ultraviolet (UV) arrays, these coatings lock in performance characteristics while preventing atmospheric dust contamination.
How global buyers translate the properties of our custom 1mm White PET Sheets into specific, high-value end-products.
In modern European and North American home design, the market is rapidly pivoting away from PVC and toward non-toxic alternatives like PETG and PET decorative sheets. The 1mm white sheet serves as an exceptionally flat substrate laminated onto MDF or particleboard panels via high-speed flat-paste machine processes or PUR hot-melt adhesives. Common usage regions include:
Due to its high impact resistance and outstanding thermal draw characteristics, the 1mm PET sheet is a primary raw material for thermoformed industrial trays, protective shells, and commercial retail components.
Why sourcing your custom 1mm White PET Sheets directly from Ganzhou Zhongyou optimizes cost, quality, and delivery timelines.
Ganzhou Zhongyou Film Material enjoys strategic geographical access to the leading domestic chemical manufacturing zones in Southern China. Our close relationships with upstream polyester monomer and titanium dioxide producers mean we secure consistent pricing and stable material grades, shields us from global raw material volatility and pricing spikes.
Equipped with state-of-the-art dual-screw co-extrusion setups, we handle both low-volume custom orders and massive container-load contracts. This production flexibility ensures exceptionally rapid lead times, taking orders from custom masterbatch mixing and extrusion to final packaging and export preparation in just 7 to 14 working days.
Our Class 100,000 dust-free coating facilities guarantee that finished sheets are completely free of surface defects, black spots, or atmospheric contaminants. This level of cleanroom control is essential for high-end optical films and laminates destined for high-gloss, premium interior panels and electronic assemblies.
Whether you require custom color matching (CIE L*a*b* coordinates), anti-static coatings, precise dimensions, or protective film masks on one or both sides, Ganzhou Zhongyou offers comprehensive custom services. Our location allows easy access to deep-water shipping lanes via major ports in Shenzhen, Guangzhou, and Xiamen.
Underpinning our manufacturing with verified compliance frameworks to guarantee consistent performance across international borders.
All functional sheets produced by Ganzhou Zhongyou are subjected to rigorous inline and offline laboratory testing protocols. These verify that physical and chemical properties align with the demands of high-performance applications:
