General Vacuum Use Systech Illinois's 8001 Oxygen Permeation Analyser and 7001 Water Vapour Permeation Analyser to Test Barrier Performance of Their Metallized Coatings

General Vacuum in Lancashire, now part of the Bobst Group have been designing and building large industrial vacuum roll coaters for use in optical, electrical and general packaging applications since 1996 and use the 8001 Oxygen Permeation Analyser and 7001 Water Vapour Permeation Analyser from Systech Illinois to test the barrier performance of their metallized coatings.

Thame, United Kingdom, February 03, 2012 --( Systech Illinois, a leading provider of permeation analysers and gas analysis equipment, has been chosen by General to test the barrier performance of metallized polymer films for permeation of oxygen and water vapour.

Based in Lancashire, General is the leading supplier of equipment and services for the folding carton, corrugated board and flexible materials industries. General supplies vacuum web coating and metallizing machinery for the deposition of conventional aluminium and clear barrier coatings for packaging and other substrates. Well known by industry leaders, General's machines are characterised by minimal downtime and superb quality at high-speeds.

Vacuum metallizing has become a viable substitution technology, depositing thin "nanometer" metal coatings onto polymeric substrates. The physical vapour deposition technique works by vaporizing the metal in a vacuum chamber and allowing the metal to condense onto the passing substrate. The integrity of this extremely thin metal layer is found to provide an excellent barrier to light, water vapour, oxygen as well as other gases and aromas.

Nick Copeland, General Product Manager at General Vacuum, said; "The amount of metal deposited on the surface of a film will govern the oxygen, water vapour transmission and light barrier properties of that film. Systech Illinois’ permeation analysers are vital to accurately and reliably measure the rate of oxygen and water transmission through the film. This will help to determine the amount of metal that is required to meet a particular application.”
