Abstract
Process for manufacturing blister packs, for example to accommodate items such as pharmaceutical items in the form of capsules, coated capsules, ampoules etc., from a base part and a lid part made from strip shaped packaging material. The base part exhibits permanently shaped recesses which are surrounded by shoulders and the lid part exhibits permanently shaped recesses which are surrounded by shoulders; the base and lid parts lie on a plane of symmetry and the base and lid parts are joined at their shoulders over the whole or part of the surface area in the region of the plane of symmetry; the recesses in the base and lid parts which are symmetrically arranged with respect to the plane of symmetry form compartments and the contents are contained in the compartments. The blister packs may be manufactured, for example, by folding or turning over an endless strip of packaging material along a line of symmetry.
