Our PET twin-screw sheet extruder represents a significant advancement in polymer processing technology, specifically engineered to overcome the traditional challenges associated with PET sheet production. Conventional single-screw systems typically require costly, energy-intensive pre-drying stages because PET is highly hygroscopic; moisture causes hydrolysis, leading to reduced molecular weight, material brittleness, and surface defects. Our solution integrates a high-efficiency vacuum degassing system directly into the twin-screw barrel, effectively removing moisture and volatile gases from the melt during extrusion. This innovative design eliminates the need for separate crystallizers and dehumidifying dryers, thereby simplifying the process and reducing energy consumption by up to 40%.

Scope Of Application
The intermeshing, co-rotating twin-screw configuration ensures superior mixing, homogenization, and gentle processing of heat-sensitive materials, guaranteeing a stable, high-quality melt. This system demonstrates remarkable material versatility, capable of processing various materials including APET, PETG, CPET, and PLA, and efficiently handles up to 100% recycled PET (rPET) flakes. The result is the production of high-clarity, high-toughness sheets with precise thickness tolerances, suitable for thermoforming packaging, food containers, and industrial applications. Offering higher output rates and exceptional melt quality, our twin-screw extrusion line is the optimal choice for manufacturers seeking efficiency, sustainability, and superior product quality.
PET sheets exhibit high transparency and are non-toxic and odorless, making them environmentally friendly and particularly suitable for easy recycling in food packaging and other applications. PET is currently an ideal thermoforming packaging material, widely used in applications such as vacuum packaging, food packaging, hardware packaging, pharmaceutical packaging, and electronic product packaging.
