Pack with integral label and projection

摘要

Packs are injection moulded with integral label and dummy walls or projections. The label is laid in the mould where it will be visible, using a label which has been perforated beforehand with a number of holes at the dummy walls or projections areas; the polymer is injected in the normal way so that it flows through the holes to fill the mould cavity and forms the dummy walls/projections.
