Abstract
Abstract A package is formed by deep-drawing a plastic foil into a mould in which has been placed a label having at least two sidewalls and a web connecting same. The label element is provided with a heat-sensitive adhesive on its inner surface so as to be secured to the plastic package by the heat of the deep-drawing step.
