The technology of the PET sheet production line fully absorbs and integrates advanced global extrusion sheet technologies from Europe and the United States. Key components, such as screws, barrels, and rollers, are selected from internationally renowned products. The energy consumption, intelligence, automation, safety standards, and process standards of the complete equipment have reached or are close to international benchmarks.
This product line holds multiple invention and utility model patents, making it a strong alternative to imported equipment while offering significant cost-performance advantages. The produced sheets are widely used for forming disposable cups, food containers, and as packaging materials for products such as toys.
The PET sheet production line is one of our company's most advanced, technologically mature, and stable sheet production lines. It employs a three-roll calendering process and primarily consists of an extruder, hydraulic screen changer, coat-hanger die, three-roll calender, cooling traction frame, and dual-position winding device. The equipment features a compact structure and superior performance, with optimized screw and barrel designs that ensure uniform plasticization, stable extrusion, high output, and long service life.
The precise shaping and calendering device, with its excellent adjustment capabilities, ensures superior sheet formation. The PET sheets produced by this equipment can be thermoformed into various packaging products, offering excellent gas barrier properties, purity, and hygiene without the need for additional additives. They also exhibit good toughness, extensibility, and recyclability, making them widely applicable in packaging for electronics, toys, food, pharmaceuticals, and the printing industry.
Compared to similar domestic equipment, this production line offers a comprehensive performance improvement of over 30%. Additionally, this production line can also be used for producing sheets from PS, PP, PE, and other materials.
