The flexible PA/PE medium barrier composite films are suitable for classic applications such as thermoforming. Each layer performs an important function: The PA layer is the crucial factor for the mechanical strength of the packaging. Working as a barrier layer, it seals in the aroma and prevents the penetration of oxygen, thereby extending the shelf life of your product. The PE layer on the inside of the packaging functions as a sealing medium and is decisive for providing airtight seams and a proper skin sealing. It serves as a moisture barrier and, although it protects your product from drying out, it also prevents the uncontrolled absorption of moisture. The tie layer between the PA and PE layers has the task of reliably tying them together so as to prevent delamination, even at high or varying temperatures.
Excellent puncture resistance and wide sealing range
Co-extruded composite films by ALLVAC consist of up to 11 layers of polyamide and polyethylene, thus ensuring excellent puncture resistance and a wide sealing range. This particular type of film, suitable for flexible packaging produced on thermoforming machines, features a wide range of applications and protects the packaged goods just as reliably in the deep-freeze sector as in pasteurisation. In addition to food, PA/PE medium barrier composite films can also be used for the packaging of technical articles.
