Protecting surfaces with antibacterial and antimicrobial technology
Drytac explains how new products imbued with antimicrobial technology can help protect surfaces from bacteria, fungi and mould in between cleaning.
Authored by Shaun Holdom, Global Product Manager, Drytac.
Keeping surfaces clean has never been more important. Doors, keypads, counters, tables – anywhere that people touch – must be cleaned regularly. Now there are some new products available that provide additional protection from within.
These products are imbued with microorganism-fighting technology during the manufacturing process, so it becomes part of the material’s physical structure and will not wash off or wear away. When bacteria contaminate the surface of the film – from human contact, environmental conditions or simply lack of cleaning – this technology helps inhibit bacterial growth. While not a replacement for regular cleaning, the treatment boosts the cleanliness of the surface in between cleanings.
Antibacterial vs Antimicrobial
There are two types of product to choose from: antibacterial and antimicrobial. Antibacterial films will protect only against bacteria, while antimicrobial films are effective against bacteria, plus fungi including mould, algae and mildew. The different effects depend on the chemistry – typically copper, silver or zinc.
Copper, Silver or Zinc Additives
The ions in copper prevent cell respiration and damage the bacterial cell membrane or viral coat to destroy it. Positively charged silver ions target and kill bacteria, fungi and certain viruses through several different means. Zinc-based additives, are broad spectrum antimicrobials, making them effective against many microorganisms including bacteria and fungi. The broader spectrum performance of antimicrobial substances makes them suitable for use in all environments.
Silver based technology can migrate out of the film and may become ineffective over 3-5 years. Zinc based technology is designed to lock into the film and to protect the surface typically up to 15 years.
15 Years of Protection with Drytac Protac AMP Surface Protection Film
PRINTING United 2020 Product of the Year winner, Drytac Protac AMP Film is a 150μ (6 mil) textured polyester film incorporating Microban® technology, that provides antimicrobial surface protection. When microbes meet the Microban reservoirs in the film, the cell wall of the microbes is disrupted – resulting in 24/7 protection for up to 15 years, even if the film is cut. Protac AMP uses an organic zinc technology, providing the wide spectrum of protection most beneficial to sensitive environments. Every batch of Protac AMP is tested for antimicrobial performance providing the utmost confidence and peace of mind for any application. It also achieves up to 15 years’ adhesive durability indoors and 5 years’ outdoors and has so far been used on drinks machines, tray tables on aircraft, and in schools and healthcare facilities.
