Large envelope production active
It was a long way to go, but finally we´re able to make large envelopes as well. This is achieved by the „Berliner“ Technique of folding the envelope materials a couple of times before welding.
It´s really tricky, since the setup has to be perfect as well as temperature and pressure control. But once this is under control the size of envelopes becomes almost unlimited.
