Extrude

Find out how KIVO uses advanced extrusion techniques to produce sustainable, tailor-made packaging solutions of the highest quality.

How extrusion works

Extruding is a continuous process that takes place 24/7 at KIVO. This involves heating and melting PE pellets in a cylinder with a rotating screw, the extruder. This screw forces the molten material forward and through an extrusion slit, giving it the desired shape. From the nozzle comes a thin-walled tube that is inflated with air to form a huge plastic balloon. After cooling, the film wrapped and possibly cut open, ready for further processing.

Durable extrusion

Within the extrusion department, sustainability plays a crucial role. We lead the way in thickness reduction and have minimal production waste, which we recycle ourselves at KIVO Recycling. We develop optimal films with a high percentage of recycled content from our own recycling plant REKS. Our insulated extruders are cooled with a closed circuit of bottom-cooled spring water. We were awarded the first prize for the MYA efficiency plan, due to our energy-efficient production processes.

Our various extruders

KIVO's machinery has grown and developed considerably since its establishment in 1966. The current machinery has 40 extruders, including 30 mono-extruders and 10 co-extruders. By using the latest technologies, training and good relations with machine suppliers, we remain at the forefront of innovative products.

Thanks to coextruders, KIVO can films produce with multiple layers, tailored to your specific requirements and needs. This offers possibilities such as different colours inside and outside (e.g. potting soil bags), good sealability on the inside and a smooth surface on the outside, and barrier-enhancing additives in the middle layer.

With customers in dozens of industries across more than 30 countries, we extensively select and test specific formulations. Various additives can be used to give special mechanical or aesthetic properties, such as friction resistance, tensile strength, static, puncture resistance, adhesion, sealability, flame retardancy, UV resistance, colouration and odour neutralisation.
