Plastic container e.g. for food, household or chemical products is made by extrusion-blowing from one or more layers with high flexure module and low density

摘要

A container, in the form of a flask, canister or tubular bottle, has its wall (50) made from at least one layer (51, 52) of polypropylene (PP) with a high flexure module and low or very low density polyethylene. The polyethylene is produced by catalysis with a catalyst of high reaction selectivity, especially a metallocene. The container's total wall thickness is 400-800, preferably 500-700 micro m.
