Here is an edited introduction to GWELL PP Sheet Extrusion Lines, incorporating technical specifications, applications, and innovations from the search results: GWELL PP Sheet Extrusion Line: Technology & Applications Company Profile GWELL Machinery is a leading Chinese high-tech enterprise specializing in plastic extrusion solutions, with manufacturing bases in Suzhou (Taicang) and Yancheng covering 150,000+ m² . Established in 2010, the company produces 200+ extrusion lines annually and exports globally to markets like Germany, Japan, and Russia . Technical Highlights 1. Multi-Layer Co-Extrusion Technology • Produces 3-layer PP/PS/PET sheets with widths of 800–1,500 mm and thicknesses of 0.15–1.5 mm . • Combines materials like PETG+APET+PETG (GAG structure) for enhanced barrier properties . • Output capacity: 300–1,500 kg/h, adaptable to single/twin-screw extruders . 2. Precision Control & Efficiency • Real-time monitoring of temperature, speed, and thickness via CE-certified automation systems . • Twin-screw venting extruders eliminate pre-drying for PET/PLA, reducing energy use by 30% . • Modular design enables rapid product switching (e.g., from PP films to flame-retardant sheets) . 3. Specialized Line Configurations • PP Hollow Sheet Lines: Produce lightweight boards (2–8 mm thick) for logistics packaging, with outputs up to 350 kg/h . • PP Foam Sheet Lines: Density options (0.3–0.6 g/cm³) for automotive interiors (e.g., sound insulation) and fold-resistant stationery . • Decorative Film Lines: Speed up to 200 m/min for wood-grain films, supporting high-fill calcium carbonate for cost savings . Key Applications Industry Products Features Packaging Food containers, battery wraps (e.g., PP cell films), conductive PS sheets High barrier, anti-static, EMI shielding Construction PP hollow formwork, partition boards 50+ reuse cycles, waterproof, eco-friendly Automotive Carpet backing, sun visors, luggage racks High impact resistance, noise reduction Consumer Goods Furniture laminates, flame-retardant films, biodegradable PLA packaging Deep embossing, recyclability Innovation & Sustainability • 5/7-layer asymmetric extrusion for high-barrier food packaging (e.g., EVOH/PP composites) . • PP construction templates replacing wood, aligning with China’s "plastic instead of wood" policy . • Solar EVA film and stone paper projects supporting circular economies . Why Choose GWELL? • Turnkey Solutions: From R&D to installation/debugging, with 1-year warranties . • Global Compliance: CE certification and ISO-quality manufacturing . • Customization: Lines tailored to width, output, and material needs (e.g., PP foam densities) . --- Summary GWELL’s PP sheet extrusion lines merge versatility, precision, and eco-efficiency, serving industries from green packaging to new energy. With 600+ annual production capacity and a focus on R&D , GWELL delivers scalable, sustainable extrusion technology for global markets.
