## Abstract

A laminated film for production of molded packaging, in particular blister packs, with a layer structure comprising an inner first plastic layer, in particular of HDPE, an aluminum layer, which is connected with the first plastic layer by way of a connecting layer, and on the side opposite the first plastic layer is connected, preferably by way of a primer layer and a further connecting layer, to a second plastic layer, in particular comprising OPA. The second plastic layer is connected to a PET layer by way of a connecting layer and that the PET layer has a thickness between 150 μm and 300 μm, preferably a thickness between 200 μm and 300 μm.

## Claims

### Claim 1

A laminated film for production of molded packagings with a layer structure comprising an inner first plastic layer an aluminium layer which is connected to the first plastic layer and on the side opposite the first plastic layer is connected to, a second plastic layer, wherein the second plastic layer is connected to a PET layer, and wherein said PET layer has a thickness between 100 μm and 1000 μm.

### Claim 2 (depends on 1)

The laminated film according to claim 1, wherein said first plastic layer comprises HDPE and has a thickness between 30 μm and 50 μm, and said aluminium layer has a thickness between 25 μm and 100 μm, and said second plastic layer comprises OPA and has a thickness between 15 μm and 35 μm,

### Claim 3 (depends on 1)

A method for production of a laminated film according to claim 1, wherein the layer structure is produced separately from the PET layer and then connected to the PET layer.

### Claim 4 (depends on 3)

The method according to claim 3, wherein the connection between the layer structure and the PET layer is achieved by means of a laminating process.

### Claim 5 (depends on 1)

The method for production of a molded packaging from a laminated film according to claim 1, wherein the laminated film is molded by a thermoforming process into a moulded packaging with recesses to hold objects and wherein the molded packaging, after filling with products, is closed tightly by sealing with a cover film.

### Claim 6 (depends on 5)

The method according to claim 5, wherein the laminated film is heated before the thermoforming process to a temperature of around 160° C.

### Claim 7 (depends on 1)

A molded packaging comprising a laminated film according to claim 1.

### Claim 8 (depends on 2)

### Claim 10 (depends on 1)

The laminated film according to claim 1, wherein said aluminum layer is connected to said first plastic layer by way of a connecting layer.

### Claim 11 (depends on 1)

The laminated film according to claim 1, wherein said second plastic layer is connected to said aluminum layer by way of a primer layer and further connecting layer.

### Claim 12 (depends on 1)

The laminated film according to claim 1, wherein said second plastic layer is comprised of OPA.

### Claim 13 (depends on 1)

The laminated film according to claim 1, wherein said second plastic layer is connected to said PET layer by way of a connecting layer.

### Claim 14 (depends on 1)

The laminated film according to claim 1, wherein said PET layer has a thickness between 200 μm and 300 um.

### Claim 15 (depends on 1)

A blister pack comprising a laminated film according to claim 1.

### Claim 16 (depends on 9)

The laminated film according to claim 9, wherein said first plastic layer has a thickness of 40 μm, said aluminum layer has a thickness of 50 μm, and said second plastic layer has a thickness of 25 μm.
