Beverage
Carbon dioxide (CO2) is a fundamental ingredient of all carbonated beverages, beer, soft drinks and mineral waters. Not only does it provide the typical effervescence that drives consumer preference, it also offers additional benefits like enhancement of flavour, boosted texture impression, visual communication of freshness and increased product stability.
Other gas and chemical products used in the beverage industry: Nitrogen is used for the pressurization of beverage cans. These cans are basically light and unstable. By adding just one drop of liquid nitrogen to the top of the can after filling, excess pressure is created, resulting in a more stable packaging that can be stacked.
Laser gas for marking plastic packaging. Packaging shrinks somewhat whenever it is washed, and also gets scratched, etc. After being washed a number of times it is taken out of production.Laser gas is also used when date-stamping lables, the marking being etched into the lable. It is customary to use caustic soda when washing return packaging.
After washing, the packaging is controlled by an analyser to ensure that no impurities remain. These analysers are calibrated using special gaseous mixtures and calibrating gases.
