ICP suck-back nozzles are a go-to nozzle for any product that tends to be stringy between filling or has a thicker consistency like cosmetic creams.
Suck-back nozzles work using a flat plunger at the top of the nozzle, which is set to detract slowly after the filling process and while the filling machine is recharging. While detracting, the plunger sucks the product slowly back into the head of the nozzle.
