The JWELL PETG Sheet Extrusion Line is engineered for producing high-quality glycol-modified PET (PETG) sheets with exceptional clarity, toughness, and thermoformability. PETG combines the strength and chemical resistance of traditional PET with enhanced flexibility and lower processing temperatures, making it the material of choice for medical packaging, electronic trays, display fixtures, and high-performance label films.
JWELL offers both single-screw and twin-screw configurations, supporting single-layer, A-B, and A-B-A multilayer co-extrusion structures. With over 25 years of extrusion expertise and hundreds of installed lines worldwide, JWELL delivers turnkey solutions from resin feeding to finished roll stock — including inline thickness control, silicone oil coating, and automated winding.
The PETG Sheet Extrusion Line is part of JWELL’s complete extrusion portfolio. Customers evaluating this PETG Sheet Extrusion Line also frequently request our Jwell Machinery and PETG Plate Extrusion Line | Jwell Machinery, which share the same proven screw, die and control platforms. For layout drawings, pricing and lead times, contact JWELL Machinery directly.
JWELL has developed dedicated extrusion systems optimized for PETG’s unique rheological properties — lower melting point, wider processing window, and superior melt strength compared to standard PET.
The JWELL single-screw extruder features a specially designed barrier-type screw geometry optimized for PETG melt homogenization. The JW-150 single-screw model achieves a measured output of 1,700 kg/h, making it ideal for high-volume PETG sheet production with consistent melt quality and energy efficiency.
Key advantages:
The CJWS95 twin-screw extruder delivers a measured output of 1,200 kg/h and is particularly suited for PETG formulations containing recycled content or functional additives. The co-rotating intermeshing screw design provides superior mixing, devolatilization, and melt uniformity.

The JWELL T-Die is precision-engineered for PETG melt characteristics, ensuring uniform flow distribution, exceptional surface clarity, and long service life.
1. Automatic Adjustment, Precise Thickness Control Equipped with electric or thermal bolt adjustment mechanisms linked with an online thickness gauge for real-time sheet thickness correction.
2. Mirror-Polished Flow Channel, Optimized for PETG Melt Mirror-polished internal channels minimize melt residence time and prevent degradation — essential for PETG’s heat-sensitive glycol-modified chemistry. Ensures crystal-clear sheets free from gel particles and flow marks.
3. Excellent Thermal Uniformity, No Dead Zones
Multi-zone heating with imported heating elements maintains die lip temperature variance within ±1°C, ensuring uniform sheet thickness and consistent optical clarity across the full width.
4. Fast Process Adjustments, Reduced Downtime
Supports rapid format switching for varying sheet thickness and width, improving line flexibility and reducing changeover time.
5. Compatible with Multilayer Co-Extrusion
Supports A-B, A-B-A, or complex multilayer PETG structures with stable flow distribution — ideal for functional barrier layers, anti-fog coatings, or recycled-content core layers.
6. High-Strength Alloy Steel, Durable and Corrosion-Resistant Constructed with high-grade die steel, heat-treated and nitrided for thermal and chemical resistance. Service life: 8–10 years.
7. Seamless Integration with JWELL Line Controls Fully compatible with JWELL’s PLC/HMI system for integrated control of die, extruder, and thickness gauge.
Applicable PETG Products:
The J-type three-roll calendar provides precise cooling, calendering, and surface finishing for PETG sheets, ensuring exceptional clarity and flatness.
1. High-Precision Three-Roller Structure Mirror-polished upper, middle, and lower rollers arranged in vertical, inclined, or horizontal configuration to meet diverse PETG process requirements.
2. Stable Sheet Thickness Control Fine-tuned roller gap control (±0.01 mm) integrated with the automatic thickness gauge ensures consistent sheet thickness and excellent flatness.
3. Excellent Sheet Gloss and Surface Quality Rollers are chrome-plated and precision-ground for outstanding clarity and gloss — free from flow marks, bubbles, or crystal spots that could compromise PETG’s signature transparency.
4. Efficient Cooling System Internal spiral water or oil circulation system controls roller temperature within ±1°C for uniform cooling, preventing internal stress and waviness in PETG sheets.
5. Advanced Tension Control & Synchronized Drive Independent servo motors drive each roller with precise tension control, preventing wrinkles and misalignment — critical for thin-gauge PETG films.
6. Quick Lifting & Die Adjustment System Quick-lift center roller mechanism enables faster threading and cleaning, with flexible die-to-roller distance adjustment for reduced downtime during product changeovers.
7. Modular Design, Compatible with Various Sheet Types Supports single-layer or multilayer co-extrusion; suitable for PETG, APET, and RPET materials.
8. Seamless Integration with Full Line Automation Integrated with extruder, die, and thickness gauge via PLC/HMI for smart operation and recipe management.
For PETG sheets requiring release properties — such as medical blister films, label base films, and electronic packaging — the inline double-sided silicone oil coating module provides uniform, high-quality surface treatment.
1. Uniform and Stable Coating Precise micro-gravure roller or comma bar coating achieves uniform, consistent silicone oil layers without streaks or skips.
2. Highly Automated Control System JWELL’s proprietary PLC system controls coating speed, thickness, and fluid ratios automatically.
3. Inline Coating — Saves Labor and Time Positioned inline at the end of the sheet line, avoiding material transfer, contamination, and static dust adhesion — improving overall efficiency.
4. Efficient Hot Air Drying System Multi-zone adjustable hot air dryer ensures fast curing of silicone oil without stickiness or residue — essential for PETG’s lower heat resistance compared to APET.
5. Single or Double-Sided Coating Supports single-sided or double-sided coating according to customer requirements.
6. Energy-Saving and Environmentally Friendly Heat recovery and exhaust treatment systems reduce energy consumption and VOC emissions in compliance with environmental regulations.

PETG sheet from Jwell lines forms rigid trays and blister packs for surgical instruments, implantable devices, catheters, and diagnostic kits that must maintain sterile integrity through EtO, gamma, or electron-beam sterilization. PETG’s high clarity allows visual inspection of device integrity through the sealed package — a regulatory requirement under ISO 11607 for sterile barrier systems where the ability to confirm device presence and condition without opening the package directly supports patient safety.
PETG’s toughness at thicknesses as low as 0.5 mm withstands the rigors of hospital distribution without cracking, and the material’s chemical resistance to common sterilization agents (EtO gas, gamma radiation, electron-beam) preserves optical clarity and mechanical integrity through validated sterilization cycles. Jwell’s process documentation package — including IQ protocol, OQ protocol with defined process window characterization, and a process validation master plan template — supports converters pursuing ISO 13485 medical device quality system certification.
For medical converters, Jwell’s silicone-free corona treatment option ensures PETG sheet surfaces remain compatible with adhesive bonding (Tyvek® lidding film), printing, and direct device contact without the contamination risks that silicone slip agents pose.
High-end cosmetic brands demand packaging that communicates product quality before the consumer opens the box. PETG sheet thermoformed into insert trays, product platforms, and transparent box components provides crystal-clear presentation with gloss levels exceeding 100 GU — the visual standard that luxury packaging buyers specify in incoming quality audits.
PETG’s excellent thermoforming detail reproduction captures fine brand embossing and logo details at moderate mold temperatures (60-80°C), and the material’s chemical resistance to cosmetic ingredients — including alcohol, esters, and essential oils — prevents hazing or crazing during extended product contact. This chemical resistance advantage over acrylic (which crazes under alcohol contact) and polycarbonate (which stress-cracks under ester exposure) makes PETG the material of choice for cosmetic packaging where the sheet may be in direct contact with fragrance or skincare formulations.
Jwell PETG lines can produce sheet in custom colors and with UV-blocking additives for luxury packaging that must maintain appearance under retail display lighting conditions.
