The amount of plastic and colour granulates used are a decisive component of the cost calculation of packaging and containers. We can offer you production options that allow you to reduce material use and replace raw plastics with inexpensive recycled materials and fillers. Furthermore, optimising the weight of articles offers a huge potential to reduce material. Bekum uses spiral mandrel extrusion heads to allow thin-walled packaging and blow-moulded parts to be produced. By using a (partial) wall thickness control, uniform layer thicknesses are produced over the entire article radius. Less effort for adjustments and optimised times for changing colours allow this technology to reduce the material requirements considerably.
