Stop sacrificing your thermoforming yield to material inconsistencies, crystal points, or stress-whitening. At HSQY, we manufacture high-performance PET sheet solutions engineered to deliver glass-like transparency, precise gauge distribution, and exceptional formability. Whether you require food-grade APET for fresh produce clamshells, sustainable RPET for retail packaging, or high-impact PETG for deep-draw applications, our sheets ensure your packaging line runs smoothly with minimal scrap.
Backed by state-of-the-art extrusion lines and advanced melt-filtration systems within our vertically integrated facilities, we guarantee strict thickness tolerances and zero impurities. From standard rigid packaging to specialized anti-static (ESD) grades for electronics, HSQY provides the exact polymer architecture your product demands.
Zero-Defect Clarity: Advanced melt filtration and highly polished calendar rollers eliminate crystal points and flow marks, ensuring flawless optical clarity for premium retail display.
Precision Gauge Control: Equipped with online thickness gauging systems, we maintain ultra-strict thickness tolerances, preventing uneven wall distribution and webbing during high-speed thermoforming.
Deep-Draw Formulation: We customize the intrinsic viscosity (IV) and impact modifiers to prevent stress-crystallization (whitening) in deep-cavity molds, ensuring structural integrity without cracking.
Surface Energy Optimization: Our sheets undergo precise corona or chemical treatment to achieve optimal dyne levels, guaranteeing vibrant, scratch-resistant adhesion for UV, offset, and screen printing.
Different end-uses require entirely different polymer structures. Explore our specialized PET matrix:
APET (Amorphous PET): The industry standard for crystal-clear food packaging, bakery trays, and fruit clamshells. Offers superior rigidity, high gloss, and excellent vacuum formability.
RPET (Recycled PET): Manufactured with certified Post-Consumer Recycled (PCR) content. Ideal for brands committed to sustainability, electronic blister packs, and non-food retail cartons.
PETG (Glycol-Modified PET): Engineered for demanding, deep-draw thermoforming and high-impact applications. Eliminates whitening during forming and provides superior toughness for cosmetic and medical packaging.
Anti-Static & Conductive PET: Specialized RPET formulations with permanent ESD protection (surface resistance 10⁶ - 10⁹ ohms) for sensitive PCBs, microchips, and electronic component trays.
*Available in custom widths (up to 1220mm), precise thicknesses (0.13mm to 2.0mm+ / 130 to 2000+ microns), and Pantone-matched colors. Supplied in roll or cut-sheet formats.
Selecting the wrong PET grade or thickness is the primary cause of packaging failures. 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 or tearing.
Thermal Profiles: Calibrating the sheet's glass transition temperature (Tg) to your oven's heating zones, preventing sagging or premature crystallization.
Post-Processing Requirements: Ensuring the surface tension (Dyne/cm) is perfectly matched to your specific ink systems and folding/creasing machinery.
Q1: What is the exact difference between APET and PETG for thermoforming?
A: APET offers the highest clarity and rigidity, making it perfect for standard shallow-draw food packaging. However, when subjected to deep-draw forming or high impact, APET can experience stress-whitening. PETG is modified with glycol, which lowers its crystallization rate. This gives PETG superior impact strength and allows it to be formed into deep, complex shapes without turning white or cracking, though it is slightly softer than APET.
Q2: What is the optimal thickness for fruit clamshells (e.g., strawberries, blueberries)?
A: 0.25mm (250 microns) is generally the engineering "sweet spot" for most berry and fruit clamshells. It provides the exact mechanical rigidity required to protect delicate produce from crushing during transit, while remaining thin enough to ensure cost-efficiency and allow for crisp, sharp thermoforming of hinges and locking buttons. For heavier produce or larger structural trays, we recommend stepping up to 0.30mm - 0.40mm.
Q3: How do you ensure the sheets will print well with UV or offset inks?
A: Printability is dictated by the surface energy of the polymer. Standard PET has low surface energy, causing inks to bead up or scratch off. We utilize inline corona or specialized chemical treatment systems to elevate the surface tension to precise Dyne levels (typically 38-42 dynes/cm). This guarantees excellent ink wetting, vibrant color reproduction, and strong adhesion for high-speed UV, offset, and flexographic printing processes.
Q4: Are your RPET sheets certified for food contact and sustainability audits?
A: Yes. Our RPET is manufactured using certified Post-Consumer Recycled (PCR) flakes that undergo rigorous washing and extrusion processes. They are fully compliant with FDA and EU 10/2011 regulations for direct food contact, BPA-free, and odorless. We provide full traceability documentation and mass-balance certificates to help your brand pass stringent retail sustainability audits.
