Flat film production with cast film extrusion machines by diamat.

Based on our many decades of experience, we supply cast film extrusion systems of highest quality.
Each line is designed according to individual requirements. Our solutions can cover the whole flat film extrusion process or single machines can be retrofitted into existing production lines.

Many years of experience in cast film extrusion

Due to our many years of experience in construction of extrusion plants, we only build systems of enormously high efficiency. Our portfolio also offers equipment for producing filled, foamed or even technically highly sophisticated films. You need co-extrusion, lamination, coating? No problem for us! Our knowledge goes far beyond the standard.

With Diamat you will always find the right solution to produce your desired flat film.
