The SWT-120D single-screw PET sheet extrusion line is specifically designed for virgin PET resin. Its single-screw configuration ensures a gentle plasticization process that minimizes molecular chain degradation, resulting in sheets with superior toughness and ductility—qualities essential for high-draw-ratio thermoforming applications. The line efficiently produces PET sheets ranging from 0.15mm to 2.0mm in thickness, catering to diverse packaging needs, from thin blister films to robust food trays. With stable extrusion performance, precise thickness control, and excellent optical clarity, the system guarantees consistent sheet quality. It is an ideal choice for manufacturers seeking superior material properties and forming performance, particularly for deep-draw products such as coffee cups and clear PET packaging boxes.

Scope Of Application
Single-screw extruders are capable of processing a wide range of materials—such as APET, PETG, CPET, and PLA—while effectively preserving the raw materials’ inherent properties; however, the proportion of recycled PET (rPET) generally should not exceed 30%. The resulting sheets feature high transparency, excellent toughness, and precise thickness tolerances, making them ideal for thermoformed packaging, food containers, and various industrial applications. With higher output and superior melt quality, our twin-screw extrusion lines are the perfect choice for manufacturers prioritizing efficiency, sustainability, and product excellence.
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.
