This material is designed for extrusion blow moulding and consists of 55% HDPE and 45% mineral. The mineral gives good stiffness and high heat conductivity. The production speed can be increased significantly and the weight of the bottle can be kept the same by reducing the wall thickness. The mineral also gives an increased light barrier. This can lead to either prolonged shelf life or removal of the black light barrier layer sometimes use for the same purpose. Our granulate can be coloured in most colours and can be used in existing machine equipment and in existing tools. Depending on what the bottle should be used for, we recommend a thin layer of pure HDPE on the inside and outside. See below for data sheet & certificate for food contact approval.
