How to foil a vapour

Foils, sachets and films, are widely used in the health care and food industries where they protect, preserve and enhance the properties everything from tissues and drugs through to coffee and mashed potato!  The key to enhanced performance and extended life is in the foil’s barrier properties, or permeability, normally to water vapour but sometimes to other common vapours.   

Versaperm’s latest meter measures this permeability directly, enabling the most appropriate choice of materials and manufacturing processes to be used.  Measurements can be configured for water vapour, as well as Oxygen, CO₂, solvents, hydrocarbons and most other gases.

Accuracy is typically in the parts per million range, (parts per billion for some gases and materials), the meter has a highly automated computerised control with multiple chambers, allowing it to cater for several samples at a time. As an added advantage, the equipment is simple to use, requiring at most minimal training and it can sometimes give results in as little as 30 minutes.  Conventionally gravimetric measurements take days or weeks and gives significantly less reliable results.

A permeability testing service is also available from Versaperm for companies that don’t have the production throughput to require their own dedicated instrument.
