WHAT IS COLD PLASMA?
Cold Plasma is known as the 4th state of matter because it exists after a gas state.
When enough energy is applied to a gas it can become ionised, changing the properties of the gas from an insulator to a conductor. It contains a mixture of reactive molecular atomic and sub-atomic particles which can be anti-microbial.
The plasma in the Sterafill system is generated by applying electrical energy via electrodes to excite the gas. Taken by themselves, several of these particles (a host of chemical species with antimicrobial properties) can kill a range of micro-organisms. Cold plasma systems can produce these particles simultaneously and directly at the point of need, thus maximising the anti-microbial potential of the technology.
A number of research studies have highlighted that, under the right conditions, this technology can kill a wide range of micro-organisms and deliver rapid surface inactivation.
A beneficial side effect of treating the packaging material with cold plasma is that it will increase the bonding of the packaging material, giving a stronger and more robust seal, so again reducing the chance of contamination after the package has been formed.
The Sterafill plasma system is generated by applying electrical energy via electrodes to excite the gas. Cold plasmas are composed of different chemical species such as ions, electrons, electronically excited molecules, UV
photons, radicals and reactive neutral species such as
reactive oxygen (ROS) and nitrogen species (RNS).
