ACTEGA introduces sustainable silver coatings that deliver sterling results
A
CTEGA, manufacturer of specialty coatings, inks, adhesives and sealing compounds for the print and packaging industry, today reveals the latest coatings to be incorporated into the extensive ACTEGA portfolio. Five WESSCO POLAR UV silver coatings, comprising four WESSCO POLAR UV flexo silver coatings and one UV offset silver coating for use from the ink duct, deliver, in combination with highly transparent overprint varnishes, highly reflective properties and brilliantly glossy effects. Additional benefits include outstanding flexibility, efficiency, overprint ability with UV offset inks, and a strong sustainability offering.
Addressing the growing importance of sustainable printing, the solvent- free WESSCO POLAR coatings provide businesses with a high-quality alternative to traditional hot or cold foil stamping and metallized board. In addition, the use of these new coatings eliminates plastic

waste and streamlines the recycling process, providing a performance and efficiency boost to users as they remove the additional foil application step from the printing process.
Product manager metallics, Andreas Käfferlein comments: “With demand for premium, high-value print products still on the rise, our UV silver coatings capture the attention of the consumer due to their luxurious quality. This makes them highly
The WESSCO POLAR UV Silver coatings are well-suited to a range of paper-based print and packaging applications including food and other sensitive packaging types, thanks to properties such as low migration and compliance with Swiss Ordinance and Nestlé requirements.
Customers will also benefit from reduced lead times and improved cost efficiency due to the avoidance of time-consuming material ordering and extended delivery periods. The high costs associated with metallised or TransMet boards are also eliminated.

Paper manufacturer launches new antimicrobial surface treatment
A
rjowiggins has launched an antimicrobial surface treatment for paper products that inhibits the ability of bacteria and viruses to survive on the surface. In independent testing to ISO 21702, a reduction in human Coronavirus was seen in as little as just one hour. Developed in response to the global pandemic, the new antimicrobial solution from Arjowiggins incorporates Biomaster, a silver-based antimicrobial technology, to proactively inhibit the growth of harmful microbes for the intended lifetime of the product, or up to 10 years.
The solution is added to paper products during manufacture to ensure particles are more concentrated at the surface of the paper. It then works to interrupt cell growth or deactivate microbes that come into contact with the surface of the product. Testing carried out by the paper manufacturer showed its new antimicrobial
technology inhibited bacterial growth, including MRSA and
E.coli, by up to 99% over a 24 hour period, and a greater than 93% reduction in human Coronavirus, in just one hour.
The surface treatment is particularly beneficial where papers are handled by multiple people or where there is a risk of microbial propagation, in hygiene critical environments such as in hospitals, classrooms and hospitality venues. It also offers added value for numerous applications, including packaging, delivery notes, medical prescriptions, restaurant menus, business cards and security papers for passports, ballot papers or cheques. Arjowiggins central research and development manager, Gael Depres explains: “The idea to develop an antimicrobial surface treatment for paper products came about at the start of the pandemic when, as a business, we wanted to play our part
during the crisis and beyond. We spoke to Addmaster, the UK’s leading additive specialist, about incorporating Biomaster into our products and, once we realised this was feasible, testing was carried out to ensure the efficacy of the solution.
“In addition to inhibiting the growth of microbes, the surface treatment does not take away from the attributes of our papers, which print with the same precision and quality, without affecting colour, appearance, recyclability or shelf life.” Arjowiggins’ new antimicrobial solution is already available across its Security Papers range and is now available on demand across its full range of uncoated Creative Papers, including HP indigo and dry toner products for digital printing. It is also compatible with all print techniques, including hot foil stamping.
