The production of thermoforming barrier films based on polyethylene and polyamide is the core competence of ALLVAC. These composite films are used in particular for the packaging of perishable foods. The Allgäu-based family business covers the entire process chain from development to extrusion and packaging, so that customers benefit from maximum flexibility and speed. ALLVAC was founded in 1992 by Hans Bresele senior and since then has drawn a continuous success curve upwards. The company’s success is based on a conservative awareness of values, a great deal of innovation and high quality standards. Thermoforming barrier films are produced in two different ways: blow extrusion to produce blown films and cast extrusion for casting the films. The choice of process depends on the desired efficiency, the final application and the required film properties, such as film thickness, gas barrier level, film strength and sealing capability.
