Abstract
A multi-layer thermoplastic packaging, the outer layer containing at least one filler having particles of different particle size and of a diameter ≧50 μm, to give a natural stone external appearance and a process for the preparation thereof which includes coextrusion and blowing of the inner and outer layers, to provide the packaging which can be in the form of a flask, bottle, pot or other desired shape.
Claims16
A thermoplastic packaging comprising at least one thermoplastic inner layer and one thermoplastic outer layer, wherein the outer layer is crack-free and comprises at least one filler having particles of variable particle size and particle diameters ≧50 μm.
A process for manufacturing a thermoplastic packaging comprising coextruding at least one thermoplastic inner layer and an outer layer containing at least one filler having particles of variable particle size and particle diameters ≧50 μm, and blowing the inner and outer layers to orient the particles of the filler in the outer layer parallel to the inner layer, and wherein the outer layer is crack free.
