Barrier films are becoming thinner and thinner with the same functionality. From a sustainability perspective, this is good news because fewer raw materials are being used. However, truly resource-saving production also requires technical measures. Allvac has therefore invested in a modern extrusion line.
A quarter of the energy used in plastics production is consumed during the Extrusion processes consumed, the VDMA determined. Manufacturers of extrusion systems have the Energy consumption per kilogramme of processed Plastics have been significantly reduced in recent years through the use of modern drive technology.
The Allvac Folien GmbH, a leading manufacturer, in its own estimation, of Barrier films made of polyamide (PA) and polyethylene (PA) has just invested in another modern extrusion line. With this, the company from Waltenhofen in the Allgäu Sustainability of its products. According to Allvac, the new system enables the use of new raw materials for higher quality films.
Films become thinner with the same functionality
„Traditional films need to be thinner and more functional in order to fulfil sustainability requirements,“ says Allvac's Managing Director Hans Bresele. Just recently, a new generation of films with optimised material thickness was presented at the IFFA in Frankfurt am Main. In addition, the films with a proportion of 67 per cent renewable raw materials such as rapeseed oil or sugar cane. We are also trialling completely polyamide-free films.
However, the Allgäu-based family business is also focussing on the entire process in its efforts to make production more resource-efficient. The aim is to reduce the amount of raw materials required, minimise Residual materials to produce and Granulate losses during production.

These measures not only increase the company's own Material and energy efficiency, According to Bresele, they also benefit the customers: „They need less film and have a much more productive Packaging process.“ Allvac also pays particular attention to energy consumption. With the help of ISO 50001, a comprehensive Energy management constructed.
Granulate is fed from the silo
We also endeavour to avoid waste materials and, where they occur, to sort and recycle them properly. Through Optimisation of batch sizes and the fastest possible elimination of production faults, no residual materials should be produced in the first place. Monomaterial-edge trim can be fed directly back into the production process inline.
According to the company, the conversion of the Granulate supply. Whereas this used to be done using many small containers, machines at the new location in Waltenhofen connected directly to granulate silos via pipework. This measure also fulfils the objectives of the „zero granulate loss“ voluntary commitment of the Industrial Association for Plastic Packaging, which Allvac has joined.
