## Abstract

A flexible pouch for packaging a product therein having a pouch panel formed of a material having a layer of polyethylene terephthalate, a layer of aluminum, a layer of nylon, and a layer of polyethylene. The layer of polyethylene terephthalate has a thickness of 12 to 15 microns, the layer aluminum has a thickness of 7 to 9 microns, the layer of nylon has a thickness of 12 to 18 microns, and the layer of polyethylene has a thickness of 70-200 microns.

## Claims

### Claim 1

A flexible pouch for packaging a product therein, said flexible pouch comprising:
a pouch panel formed of a material having a layer of polyethylene terephthalate, a layer of aluminum, a layer of nylon, and a layer of polyethylene,
said layer of polyethylene terephthalate having a thickness of 12 microns;
said layer of aluminum having a thickness of 7 microns;
said layer of nylon having a thickness of 15 microns;
said layer of polyethylene having a thickness of 80 microns,
wherein said layer of aluminum is positioned between said layer of polyethylene terephthalate and said layer of nylon, and
wherein said layer of nylon is positioned between said layer of aluminum and said layer of polyethylene.

### Claim 2 (depends on 1)

The flexible pouch of claim 1, wherein said polyethylene is a linear low density polyethylene.

### Claim 3

The flexible pouch 1, wherein said layer of polyethylene terephthalate, said layer of aluminum, said layer of nylon, and said layer of polyethylene are laminated in order to form the pouch panel.

### Claim 4 (depends on 1)

The flexible pouch of claim 1, wherein said product is an alcoholic beverage.

### Claim 5

A method of forming a flexible pouch for packaging a product comprising:
laminating a layer of polyethylene terephthalate, a layer of aluminum, a layer of nylon, and a layer of polyethylene to form a pouch panel; and
forming a body of said pouch from said pouch panel;
said layer of polyethylene terephthalate having a thickness of 12 microns;
said layer of aluminum having a thickness of 7 microns;
said layer of nylon having a thickness of 15 microns;
said layer of polyethylene having a thickness of 80 microns,
wherein said layer of aluminum is positioned between said layer of polyethylene terephthalate and said layer of nylon, and
wherein said layer of nylon is positioned between said layer of aluminum and said layer of polyethylene.

### Claim 6 (depends on 5)

The method of claim 5, wherein said polyethylene is a linear low density polyethylene.

### Claim 7 (depends on 6)

The method of claim 6, wherein said layer of polyethylene terephthalate, said layer of aluminum, said layer of nylon, and said layer of polyethylene are laminated in order to form said pouch panel.

### Claim 8 (depends on 6)

The method of claim 6 further comprising:
filling said flexible pouch with an alcoholic beverage.
