Co-extruders - Import export

Sweet creamy fillings in a moulded, crisp extrudate shell The latest in sophisticated products from direct extrusion are the co-extruded, centre filled products. In these products a soft filling with a pumpable viscosity is metered continuously, using a suitable pump, into an extruded pipe, simultaneously while it is being extruded. A special design co-extrusion die is used for this purpose. The result is an extruded pipe filled with a creamy mass. This pipe can then be moulded into various shapes continuously with the help of special moulding rollers. Raw-materials: It is important to choose a proper combination of the extrudate raw-materials and the filling mass in these kinds of products to ensure that they combine harmoniously in the final product to give a compatible eating experience to the consumer.

In the extrusion process the TPE pellets are poured into a hopper are heated in the barrel and turned into a melt by this heat and shear. A screw carries the melted plastic through a shaped die to produce continuous lengths of shapes with the same profile, which are then cooled by air or water. Our TPE compounds are easily extruded into single and complex profiles. They can also be co-extruded with other materials to yield a part with both rigid and soft components. They exhibit improved profile flexibility. The SEBS compounds, with their saturated intermediate blocks, are very stable against thermal degradation. On the other hand, the SBS compounds degrade if overheated or if a screw with excessively high compression ratio is used. The information below is intended as a general overview, settings may vary depending on the specific grade selected.

POLIFILM manufactures construction films and thermal plastic films which ensure reliable insulation and high living quality. We offer solutions for all fields of application - mono films, co-extruded products and complex individual formulas.

POLIFILM surface protections films have been successfully used for the protection of decorative laminates for decades. Depending upon the gloss level of the laminates low adhesion level films (for high gloss surfaces) or higher adhesion films (for rougher finishes) are used. Typically transparent films are used as they allow quality inspection of the decorative surface without a need to remove the films for this process. For 2D and 3D applications with special requirements we offer several solutions. Co-extruded, uncoated protection films present a good solution for these requirements.

Our co-extruded silo films offer the optimum cover of grass or maize silage in bunker silos and thus ensure perfect conditions for the production of high quality feed. The effect of the films can be increased with the combined application of underlay films. Our silo films are available in the colours: black / black black / white green / white white / white green / black silver / green in widths of 4.00 m to 18.00 m.

One of our focus areas is the protection of polycarbonate (PC) and polyvinylchloride (PVC) sheets and films. Hereby POLFILM offers the widest product assortment in the market. Apart from adhesive coated films we are offering an ever more comprehensive range of uncoated, coextruded cast films, whereby the film and the adhesive system are (co-)extruded in one step. This is an innovative, economic and at the same time environmentally friendly solution. Furthermore we offer solutions for the protection of plastic sheets based on PMMA, ABS and PS for standard applications as well as for special applications such as thermoforming or optically challenging applications such as electronic display applications.

In addition to adhesive coated protection films, POLIFILM is also offering coextruded, uncoated yet self-adhesive films since more than 12 years. These protection film solutions combine the film manufacturing process (film extrusion) and the adhesive extrusion in one process. The traditional process requires typically at least 2 steps. This co-extrusion process presents a clear productivity gain also for our customers. We develop co-extruded protection films together with our partner, who has a long time experience in the development and production of cast films. Our joint technological experience presents an ideal platform for the development of ever more demanding requirements of our customers now and in the future.
