Frequently Asked Questions
What does a water squeezer do in film recycling?
A water squeezer mechanically removes water from washed plastic films and bags before final drying. Because films trap large amounts of surface water, thermal drying alone would be slow and energy-hungry — squeezing the bulk of the water out first dramatically cuts dryer load, energy use, and overall processing cost.
How is a water squeezer different from a centrifugal dryer?
Both remove water mechanically, but they suit different materials. Centrifugal dryers spin rigid flakes outward against a screen, while a squeezer compresses soft, flexible films to press water out. Films would tangle or blind a centrifuge screen, so the squeezing action — combined here with densifying — is the right approach for films and bags.
Why combine dewatering with densifying?
Washed films are bulky and hard to handle even after dewatering. Densifying compacts them into a dense, free-flowing form with much higher bulk density, which feeds pelletizing extruders far more consistently than loose film. The combined squeeze-and-densify step therefore bridges washing and pelletizing in a single efficient unit.
How dry does the film get after squeezing?
Mechanical squeezing removes the majority of surface water, but some residual moisture typically remains — which is why thermal drying or the pelletizer’s own degassing usually follows. The exact final moisture depends on film type, contamination, and downstream equipment, so share your process details for a realistic expectation.
Where does the water squeezer fit in a recycling line?
It sits directly after the film washing stages and before final drying or pelletizing. Washed, wet film enters the squeezer-densifier and exits as dewatered, densified material ready for the extruder. Placing mechanical dewatering here keeps the most energy-intensive step — thermal drying — as small and efficient as possible.
