A cover foil as a push-through foil for a blister pack for packaging moisture-sensitive products has an aluminum foil as the barrier layer against the penetration of water vapor and gases and a sealing layer for sealing against a blister base part. A plastics material layer containing moisture-adsorbing drying agent is arranged on the side of the aluminum foil provided with the sealing layer.

Cover foil as a push-through foil for a blister pack

There is provided a blister form medicament pack comprising (a) a base sheet in which blisters are formed to define pockets therein for the containment of inhalable medicament; and (b) a lid sheet which is sealable to the base sheet except in the region of the blisters and mechanically peelable from the base sheet to enable release of said inhalable medicament. The base sheet and/or said lid sheet have a laminate structure comprising (a) a first layer of aluminum foil; and (b) a second layer of polymeric material of thickness from 10 to 60 micron, said polymeric material having a water vapor permeability of less than 0.6 g/(100 inches) (24 hours) (mil) at 25&#xb0; C.

Blister package for inhalable medicament

Packaging containers produced from a composite shaped by cold-forming, the term &ldquo;packaging containers&rdquo; including base or lid parts or base or lid parts shaped by cold-forming. The base or lid parts can be shaped by cold-forming, and a lid foil or base foil, respectively, can form the corresponding closure for the packaging container. In addition, both the base and the lid part can be shaped by cold-forming, the depressions formed in the base and lid parts advantageously lying opposite one another. Examples of these packaging containers are strip packing or blister packaging for pharmaceutical products. The composite from which the packaging container or parts thereof are produced has a layered structure, for example, comprising: (a) a plastics foil between 10 &mgr;m and 250 &mgr;m thick; (b) a bi- or monoaxially oriented foil selected from the group comprising polyvinylchloride foils, polyolefin foils, polyamide foils or polyester foils between 10 and 100 &mgr;m thick, or a bi- or monoaxially oriented plastics foil composite comprising two foils selected from the group comprising polyvinylchloride foils, polyolefin foils, polyamide foils or polyester foils each between 10 and 50 &mgr;m thick; (c) a metal foil between 20 and 200 &mgr;m thick; and (a ) a plastics foil between 10 and 250 &mgr;m thick. The packaging containers are characterized by a high degree of flatness and/or rigidity.

Packaging container

The invention concerns packaging container produced from a composite shaped by cold-forming, the term &ldquo;packaging containers&rdquo; including base of lid parts or base and lid parts shaped by cold-forming. The base or lid parts can be shaped by cold-forming, and a lid film or base film, respectively, can form the corresponding closure for the packaging container. In addition, both the base and the lid part can be shaped by cold-forming, the depressions formed in the base and lid parts advantageously lying opposite one another. The composite from which the packaging container or parts thereof are produced has a layered structure, for example, comprising: a) a plastics film between 10 &mgr;m and 250 &mgr;m thick; b) a bi- or monoaxially oriented film selected from the group comprising polyvinylchloride films, polyolefin films, polyamide films or polyester films between 10 and 100 &mgr;m thick, or a bi- or monoaxially oriented plastics film composite comprising two films selected from the group comprising polyvinylchloride films, polyolefin films, polyamide films or polyester films each between 10 and 50 &mgr;m thick; c) a metal foil between 20 and 200 &mgr;m thick; and a ) plastics film between 10 and 250 &mgr;m thick. The packaging containers are characterized by a high degree of flatness and/or rigidity.

Cold formable laminate films

A substrate with an organic undercoat as bonding layer for a printing medium to be deposited subsequently on the substrate in a printing process is such that the organic undercoat contains fine grained constituents of organic and/or inorganic substances, whereby the surface of the inorganic constituents is treated or provided with a coating of organic substances. Suitable inorganic constituents are e.g. highly dispersed silica, the surface of which is treated with a resin or a polymer. Suitable compositions for the organic undercoat layer on the substrate are organic coatings based on many commercially available organic coating materials with an addition of e.g. 0.3 to 20 wt. % silica. By adding highly dispersed silica to the undercoat the adhesion between the undercoat and the printing medium can be greatly improved, also in the case of laser printing methods with small thermal energy.
