What´s the goal for recycling machines and packaging now

and in future?

Worldwide Plastic

consumption

rises by 5 - 8% a year

increases from 49M tonnes in 2015 to

85 Mio t by 2020

EREMA Preconditioning Unit

Gentle melting – advantages

• The melting process is extremely gentle due to

ideal material heating in the preconditioning unit

• Short extruder, very low shearing forces

• Therefore contaminants do not get carbonized

=> no smell problem

• The contaminant particles remain large =>

efficient filtration

Double filtration:

5. High efficient triple degassing

The new RegrindPro® features convincing, high-performance

degassing. This takes place very effectively in three stages: initial

degassing already occurs in the preconditioning unit. Step two is

reverse extruder degassing – made possible through optimised

screw design. The final double venting degassing at the extruder

is particularly effective and removes gas inclusions which are

still present from the melt
