Stop compromising your premium packaging with crystal points, stress-whitening, or condensation fogging. At HSQY, we manufacture optical-grade Clear PET, RPET, and PETG sheets that deliver glass-like transparency, precise gauge distribution, and specialized surface functionalities. Whether you require pristine clarity for cosmetic displays, permanent anti-static protection for electronic trays, or anti-fog performance for cold-chain foods, our sheets ensure your packaging line runs smoothly with minimal scrap.
Backed by advanced melt-filtration systems and online thickness gauging within our vertically integrated facilities, we guarantee strict tolerances and zero impurities. From standard 250-micron fruit blister packs to heavy-duty 800-micron industrial trays, HSQY provides the exact polymer architecture your high-speed production and printing processes demand.
Zero-Defect Optical Purity: Our multi-stage melt-filtration technology and highly polished calendar rollers eliminate crystal points, black spots, and flow marks, ensuring flawless transparency for premium retail displays and high-fidelity UV printing.
Anti-Whitening Deep-Draw Formulation: We strictly control the resin's intrinsic viscosity (IV) and incorporate specialized impact modifiers to prevent stress-crystallization (whitening) at sharp corners and deep cavities during vacuum forming.
Precision Gauge Control: Equipped with online beta-ray thickness gauging, we maintain ultra-strict thickness tolerances, preventing web-tracking issues and ensuring uniform wall distribution on high-speed automatic thermoforming machines.
Surface Energy Optimization: Our sheets undergo precise inline corona treatment to achieve optimal dyne levels (typically 38-42 dynes/cm), guaranteeing vibrant, scratch-resistant ink adhesion for offset, screen, and flexographic printing.
Different end-uses demand entirely different polymer structures and additive packages. Explore our specialized Clear PET matrix:
Food-Grade Virgin APET: The industry standard for crystal-clear bakery dome lids, fruit clamshells, and cosmetic windows. 100% odorless, BPA-free, and fully compliant with FDA and EU 10/2011 direct food contact regulations.
Permanent Anti-Static (ESD) PET/RPET: Critical for thermoforming IC trays and transport carriers for sensitive PCBs. Utilizes permanent conductive masterbatches to ensure stable surface resistance (10⁶ - 10⁹ ohms) regardless of ambient humidity.
Anti-Fog Coated PET: Engineered for fresh salads, berries, and chilled meats. Our permanent hydrophilic treatments prevent condensation droplets from obscuring the product, maintaining retail visibility throughout the cold chain.
High-Impact Clear PETG: Glycol-modified for demanding, deep-draw thermoforming and heavy-duty applications. Eliminates whitening during forming and provides superior shatter resistance for luxury cosmetic folding boxes and medical packaging.
*Available in custom widths (up to 1220mm), precise thicknesses (0.13mm to 2.0mm / 130 to 2000 microns). Density: 1.35 g/cm³. Supplied in continuous roll or cut-sheet formats.
Selecting the wrong Clear PET grade or thickness is the primary cause of packaging line waste. Our engineers will help you define:
Draw Ratio & Mold Geometry: Matching the material's elongation at break to your mold's depth-to-width ratio to prevent corner thinning, tearing, or structural collapse.
Thermal Profiles: Calibrating the sheet's glass transition temperature (Tg) to your oven's heating zones (typically 100°C-120°C), preventing sagging or premature crystallization.
Functional Additive Matching: Determining whether your application requires anti-fog for cold-chain visibility, or ESD protection for electronic component safety.
Q1: What is the exact difference between standard Clear PET and PETG for transparent packaging?
A: Standard Clear PET (APET) offers the highest rigidity and glass-like clarity, making it perfect for standard shallow-draw food packaging and retail windows. However, when subjected to deep-draw forming or high impact, APET can experience stress-whitening. PETG is modified with glycol, which gives it superior impact strength and allows it to be formed into deep, complex shapes (like heavy cosmetic bottle holders) without turning white or cracking, though it is slightly softer than APET.
Q2: How does your Anti-Fog PET maintain clarity in refrigerated environments?
A: In cold-chain environments, temperature fluctuations cause moisture to condense into tiny water droplets on standard plastic, creating a "fog" that hides the food. HSQY utilizes advanced hydrophilic anti-fog treatments that lower the surface tension of the sheet. This causes condensation to spread evenly into a thin, transparent film of water rather than forming light-scattering droplets, ensuring your fresh salads and berries remain highly visible to consumers.
Q3: Will the anti-static (ESD) protection on your electronic trays wear off after wiping?
A: No. Cheap anti-static sheets rely on topical chemical sprays that degrade with physical wiping or low humidity. HSQY incorporates permanent conductive masterbatches directly into the PET/RPET polymer matrix during extrusion. This guarantees a stable surface resistance (10⁶ - 10⁹ ohms) that is completely independent of ambient humidity and lasts for the entire lifecycle of the packaging, protecting sensitive PCBs and microchips from ESD damage.
Q4: Why does ink sometimes scratch off Clear PET sheets after UV printing?
A: Ink adhesion failure is caused by low surface energy. Untreated PET is chemically inert, causing inks to bead up or peel off. HSQY utilizes precision inline corona treatment to elevate the surface tension to strict Dyne levels (typically 38-42 dynes/cm). This micro-roughens the surface and increases chemical polarity, guaranteeing excellent ink wetting and permanent adhesion for high-speed UV, offset, and screen printing processes on your retail packaging.
