Continuous belt screens, refers to reverse dutch weave filter belts made of stainless steel wires. The continuous (automatic) belt screens are innovation of extruder screens. They are used for screening impurities out of molten plastic. Used with screen changers, the automatic belt filter system allows continuous and uninterrupted production and high filtering performance in cast film and blown film production and other plastic filtering process.

The continuous belt screen is widely used in various screen changers to filter out impurities in the polymer extrusion process without interrupting the process.
It is mainly used for filtering cast film and blown film, compounding, resin production, nonwovens and specialty materials.
This type of filter screen are widely used for plastic extrusion and melt filtration in plastic industry for PP, PS, PVC, PET, PE, ABS, PMMA in belt style continuous screen changers.
