Clean film for clean water

20. April 2011

A modernised drinking water filling line for the Federal Agency for Technical Relief (THW) in Ibbenbüren is filling drinking water into LiquidFlex® film bags.

This food-safe tubular film is being supplied by Bischof + Klein, Lengerich-based manufacturer of flexible packaging and technical films. The pilot line, a graduation project undertaken by three trainee technicians at the Heinrich-Hertz Vocational College, was presented to the public in Düsseldorf and handed over to the THW in April. It is intended for the Ibbenbüren district association, which will keep it in readiness for future missions.

Providing a supply of drinking water is one of the central tasks undertaken by relief organisations in areas hit by crises and disasters. The advantage of the pilot line from Düsseldorf: it decants water into 1-litre bags instead of canisters under hygienic conditions. Canisters are problematic because they take up a great deal of space when transported. If the canisters are used several times, hygiene is no longer guaranteed. In contrast, the film is wound up reels to save space prior to filling, and is guaranteed to be clean. It is manufactured at B+K under clean room conditions in a low-germ environment.

The client for the three trainee technicians, Daniel Braun, Günter Strathmann and Daniel Endres, was the THW. The project received financial support from the Agitas-Circle Erkrath e.V., a charitable association for medical and humanitarian aid. Bischof + Klein provided one of its innovative films in the form of LiquidFlex®. Thanks to a specially developed recipe, the film has zero impact on taste and is odourless – important requirements for storing drinking water. André Altevogt, head of sales for the foodstuff industry at B+K, is delighted about the successful project, which he sums up as follows: "Clean film for clean water."
