ABSTRACT:
A method of and apparatus for treating a polyolefin surface to become receptive to inks and adhesives is disclosed. The present invention provides a method of and apparatus for treating a polyolefin surface to become receptive to inks and adhesives, using the steps of introducing the shaped object onto a conveyor belt; conveying the shaped object towards an output end of the conveyor belt; aligning and guiding the shaped object across a treatment device to treat the entire 360.degree. surface of the shaped object. The treatment device includes, for example, an electrode spark generator.
