June 2010 - New film stretching plant for mf-folien A part of the clip chain New film stretching plant for mf-folien The Lindauer GmbH supplied one more film production line for biaxially oriented polyamide film to a local company. Polyamide (PA) film in general is used for food packaging. Also in the sector of film production lines for different materials DORNIER is one of the global market leaders, though nearly 100 % of these plants are sold abroad. Particularly in countries with hot climate such as China, India and Mexico there is an increasing demand for packaging film. This order was placed with DORNIER in 2009, it is already the second line which will be supplied to the company mf-folien, a medium sized enterprise located in Kempten in the Allgäu region. Headed by its founder and owner Max Müller this company is the European market leader in PA film production and manufactures PA cast film since many years. With the DORNIER line the film is being stretched to a final width of 5300 mm resulting in a final film thickness of 12 to 25 µm only. For comparison: one micrometer equals a thousandth millimeter, a human hair indeed has a thickness of 70 micrometer. The plant - designed in a special compact construction but still with a length of approx. 100 meter - is estimated to start up in the middle of September 2010 and will produce about 5500 tons first-class PA film a year. On this line the cast film is cooled, after this stretched, first in longitudinal direction and secondly in transverse direction which means oriented and finally wound to rolls on coils. For the application in food packagings the PA film is coated (adhesively bonded) with a PE film. By the combination of both materials humidity is able to exhaust, on the other hand the flavor will be kept within the wrapping. Besides the PA layer can be printed. The company of Max Müller not only is specialized on this kind of PA film but also on films which have been specifically developed for the production of composite materials (glass/carbon) applied in aircraft construction as well as naval architecture serving here as release film. Furthermore polyester films which are used for packaging applications for medical products are part of the product range. After facing a rough time during the global economic crisis, the CEO Peter D. Dornier of Lindauer DORNIER GmbH is delighted that both sectors, weaving as well as special machinery department, realize a recovery. On his part Max Müller was pleased to spend a visit to the DORNIER plant in Esseratsweiler to inspect the parts which are now about to be assembled to the new film stretching line in Kempten. The first line of its kind was supplied by DORNIER in 2002.
