Small tubes purged

The small plastic tubes in aerosol cans are purged with nitrogen to ensure that they are free of impurities before the spray cap is placed on the cans in the production line. Italian company Farmol's Hungarian subsidiary in Nyírbátor manufactures aerosol cans for pharmaceutical and cosmetic products as well as household chemicals. Farmol's customers include companies like Henkel and Schwarzkopf. Messer supplies the nitrogen in cylinders.
