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.
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.

The right packaging serves as some kind of business card for your product: The outer wrapping catches the customers’ attention and thus determines at first glance whether they will reach for your product. In order to meet our customers’ demands, we have specialised in the production of composite films. Carefully selected, high-quality raw materials from innovative, renowned suppliers and continuous improvements of film structure and production methods guarantee the success of our high-grade composite films. We will be pleased to meet your needs for tinted, printable, peelable and antifogging films.
➤ Optimal, aesthetic product presentation
➤ High degree of transparency
➤ Very good machinability for exceptional ease of processing
➤ High barrier levels
➤ Excellent puncture resistance
The AV is the classic of our variety of composite films featuring a wide range of applications. With its 5-7 PA/PE layers, available in thicknesses from 70 to 300my, it runs perfectly as a bottom film on thermoforming packaging machines, due to its excellent formability. This standard film offers a medium barrier against oxygen and water vapour. Its high degree of transparency and gloss make the products stand out at the point of sale, while its excellent sealing properties, puncture resistance and exceptional mechanical strength are equally impressive. The AV tolerates temperatures of up to 70°C for up to 2 hours and is therefore also suitable for pasteurisation.
