Abstract

Here is a new method producing a bottle preform (11) in an injection mould. A set quantity of first plastic is injected into the mould cavity. Then a set quantity of recycled material is injected, to form an annular core within the first material. The new aspect of the method is parallel injection of recycled material together with a fraction of first material. Also claimed is the preform for blowing a container, e.g. a bottle. It includes the container neck region (13), a body section (16) and a base (17), together with the annular core of recycled plastic and internal and external layers of another plastic. A novel feature is the thickness of the innermost layer, which is a multiple of the outer layer thickness.
