Our antimicrobial technology is primarily effective against bacteria, but it is also highly effective against the growth and proliferation of enveloped viruses on porous surfaces such as paper.

PaperGard has now proven to be effective at reducing the presence of SARS-CoV-2, the virus that causes Covid-19, on the surface of paper.

The latest test results show that protected papers reduced the viability of the viral strain by over 95% in only 15 minutes, and by 99.9% within 2 hours when tested against ISO 18184. PaperGard utilises technology that is built into the paper during manufacture, without affecting its appearance.

The latest test results demonstrate that there need not be a compromise on hygiene when using paper products within your department.

How effective is silver ion technology on paper?

The latest testing with SARS Cov-2 (the COVID-19 virus), using the ISO 18184 testing method to determine anti-viral activity, shows papers containing the PaperGard technology were proven effective at reducing the viability of the viral strain by over 95% in just 15 minutes.

In tests and clinical trials PaperGard wth Biomaster has been proven to reduce the overall level of MRSA and E.Coli bacteria on the paper surface by up to 99.99% using the ISO 20743 testing method to determine anti-bacterial activity conducted in an independent, internationally recognised laboratory.


Can silver ion technology safeguard against Coronavirus?

We have data showing that PaperGard (>95% inactivation within 15 minutes) is highly effective against SARS Cov-2, the virus responsible for Covid-19, on the paper surface.

PaperGard anti-microbial technology is effective 24/7 for the lifetime of the treated article. PaperGard can therefore complement current hygiene guidance offering additional product protection.

What is the Science behind it?

The Science behind Papergard and its unique technology

Infogram about papergard

Unlike antibiotics, micro-organisms are unable to build up a resistance to the way in which silver ions disrupt their growth.

  1. Silver ions bind to the cell wall of the micro-organism; preventing growth

  2. Silver ions interrupt enzyme production; stopping the micro-organism producing energy

  3. Silver ions interrupt the cell’s DNA; preventing DNA replication and new cell formation

What can silver treatment protect against?

Independent laboratory tests have proven the technology to inhibit the growth of bacteria and viruses including:

  • Staphylococcus aureus (MRSA)

  • Salmonella

  • Legionella

  • Campylobacter

  • E.coli

  • Vancomycin-resistant Enterococcus (VRE)

  • Norovirus

  • Feline Coronavirus

  • SARS Cov-2



How long is the treatment effective for?

The silver ion treatment in PaperGard is effective for the life of the product, it is built into the paper during manufacture and it cannot be removed with any amount of wear and tear. It becomes an integral part of the material.


Does the treatment affect a product in any way?

No. You can’t see, smell or even taste it!


How do I know my product has protection?

You can rest assured that when you stipulate PaperGard treatment on your product, there is a chain of custody in production to verify the legitimacy of our material.

If required, certification can be organised via an independent laboratory.
