masterbatches are intended to deal with this problem. It does not identify the active ingredient but says d2p is effective against gram positive and negative bacteria, mould, mildew, algae, fungi and viruses. It has obtained FDA approval for d2

antibacterial food-packaging, which applies to all types of polyolefins, and polyester film for wrap- ping bread. Health Canada has also approved d2

for bread packaging. Commercial use has com- menced, the company says, and successful customer-led trials have recently been completed on plastic water pipes and tanks. Swiss company Sukano says it has developed a
range of antiviral masterbatches to prevent plastic parts from becoming a possible transmitter for viruses. Initially developed for personal protective equipment (PPE) used to protect against SARS CoV-2, they are now formulated and suitable for extended applications and polymers. The company says there is an increasing custom- er demand to provide virus transmission protection in areas beyond PPE, such as industrial applications or durable goods that are frequently touched but not necessarily as frequently cleaned. It cites panels and buttons in lifts, which are touched by different people many times during a day. Sukano has run tests in a certified external
laboratory specialised in microbiological testing. Results confirmed the effectiveness of the master- batches on various viruses with a reduction of up to 99.9% on an item’s surface within the first 30 minutes. “We developed the masterbatch further into other carrier systems such as ABS, PC, PA, PET and PLA”, says Onno Treur, Business Development Manager at the company. “This enables a broader field of applications for anti-viral surface protection such as in the E&E market.” Polygiene company Addmaster, an additives

and masterbatch company well-known for its antimicrobial products, says extensive testing has shown that its Biomaster antimicrobial is active against SARS-CoV-2. Tests carried out according to ISO 21702 for non-porous surfaces (including plastics) showed a 68% reduction of SARS-CoV-2 in 15 minutes and over 99% in four hours (Figure 2). Many (but not all) Biomaster products are based on silver ion technology. Addmaster sells them in the form of powders, liquids and masterbatches. One compounder using Biomaster is Germany- headquartered Mocom, which is using it in its Alcom HM compounds. Available in a range of base resins, these are aimed at inhibiting microbial growth in technical hygienic applications. The compounder says the HM products “combine a durable antimicro- bial product protection of the plastic material with individual customer requests regarding specific colours and material properties such as stabilisation, impact strength or reinforcement.”
Mocom says the Biomaster technology it uses is based on silver ion technology and is compliant with the EU Biocide Regulation EU 528/2012 and Article 95 therein. “The Alcom HM compounds are classified as treated articles and are in line with the requirements of Article 58,” the company says. According to Mocom, the silver ions on the plastics surface have been tested against more than 50 different types of bacteria, such as
E.coli, Campylobacter, Legionella, MRSA and Salmonella. It says the antimicrobial effect of silver ions is apparent after 15 minutes, with a typical reduction of up to 99.9% after 24 hours.
