Abstract

Provided is a method for producing a sealed-edge pouch with a laminate composite stored therein. In some non-limiting embodiments or aspects the laminate composite is detached from a laminate composite web having a carrier film with substrates which are arranged thereon and are covered by means of a respective cover film. An intermediate body is supplied to the laminate composite web or to the laminate composite or is moulded into the carrier film such that the intermediate body or the intermediate bodies surrounds/surround all of the free surfaces of the substrate at least in regions. The laminate composite and all of the intermediate bodies are introduced between two packaging material webs. The packaging material webs are sealed to each other. Finally, the sealed-edge pouches are separated. A device for producing sealed-edge pouches and a sealed-edge pouch produced according to this method are also provided.

First claim

The invention claimed is:

1. A method for producing a sealed-edge pouch with a laminate composite stored therein, the method comprising the following steps in sequential order:
supplying a laminate composite web, the laminate composite web comprising a carrier film with adhesive-containing substrates arranged on the carrier film, wherein each of the adhesive-containing substrates is covered by a cover film,
supplying an intermediate body to the laminate composite web or moulding the intermediate body into the carrier film of the laminate composite web such that the intermediate body surrounds free surfaces of the adhesive-containing substrates at least in regions,
detaching the laminate composite from the laminate composite web,
introducing the laminate composite and the intermediate body between two packaging material webs,
sealing the packaging material webs to each other, and
separating sealed-edge pouches therefrom.

2. The method according to claim 1 , wherein sealing the packaging material webs to each other takes place during conveying the laminate composite by a second conveyor device.

3. The method according to claim 1 , wherein a surface of the intermediate body that faces each of the adhesive-containing substrates has the same adhesive properties as a surface of the carrier film which faces each of the adhesive-containing substrates.

4. The method according to claim 1 , wherein the cover film is labelled.

5. The method according to claim 1 , wherein the carrier film comprises two carrier film sections overlapping in regions to form an overlap, and wherein each of the adhesive-containing substrates sits on the overlap.

6. The method according to claim 1 , wherein the intermediate body supplied to the laminate composite web is a protective film.
