Hard-coated polyester film from MacDermid Autotype incorporating Microban antimicrobial protection has undergone extensive testing by one of the UK's leading independent, analytical testing bodies
The antimicrobial properties of the new substrate were tested against a number of harmful bacteria, including MRSA and E coli 0157.
For both of these bacteria, Autotex AM with Microban antibacterial protection demonstrated a kill rate of more than 99%.
Using standard test protocols that simulated real life cleaning regimes, Autotex AM with Microban antibacterial protection was subjected to a period representing 15 years of usage.
The tests were carried out on a variety of different samples, including unprocessed samples taken straight from the production line, plus samples that were subjected to simulated graphics printing such as jet dryer passes, fusion UV passes and passes under IR lamps.
In addition, film samples underwent testing to simulate extreme surface wear; this included the texture being partly removed using sand paper and the surface polished using wire wool until it was smooth.
Finally, to simulate the process of embossing, film samples were stretched by 20% in both MD and TD directions.
"This level of testing is designed to give customers and end users the confidence in the long term performance of the new Autotex AM with Microban antibacterial protection substrate," Emma Scowen, industrial product manager for Autotype International explains.
"These test results are excellent news in terms of addressing the problems of MRSA, as the film can be used for any hygiene critical surface application where preventing the growth and spread of bacteria is essential.
"The substrate is ideal for any surface application such as membrane keyboards, fascia panels, wall coverings, shelf and bench tops".
