US – Microban International has launched LapisShield, a novel, non-heavy-metal technology designed to seamlessly integrate antimicrobial functionality into any water-based coating formulation.

The technology inhibits bacterial growth by up to 99.99%, preventing the formation of mold and mildew, protecting treated surfaces from microbial degradation.

Michael Ruby, President at Microban International, says: “We are excited to introduce LapisShield as the latest example of Microban’s commitment to developing sustainable, non-heavy-metal antimicrobial technologies for its partners worldwide.

Our coatings experts have worked to deliver a more environmentally friendly technology that offers the best quality and compatibility for water-based coating systems.”

As well as keeping product surfaces in good condition for longer periods of time, the coating is said to resist stains and odors.

It is supposedly compatible with thin coating systems and reportedly offers enhanced UV stability, meaning it can be applied to transparent glass or plastic.

LapisShield coating batches can also be stored for future use to make the best use of resources and prevent unnecessary waste.

“The stability and clarity of LapisShield allow it to be easily integrated with a wide variety of coatings systems, including anti-fingerprint and anti-smudge formulations and applications requiring optically clear performance,” added Ruby.

Following the COVID-19 pandemic, hygiene has come to the forefront of packaging design. Antimicrobial packaging provides customers with an increased level of product protection against potentially harmful microbes.

Earlier this year, Schur Flexibles developed an antibacterial varnish for applications such as food packaging, apparently reducing the amount of bacteria present on packaging by 95%.

The antibacterial varnish has been tested and reportedly confirmed safe for food packaging, including meat, dairy, and fish, as well as for cosmetic packaging and other applications.

For instance, Duda, a producer of meats and sausages, has been using the coating in Poland to reassure consumers during the pandemic.

In addition, Schur Flexibles said that manufacturers do not need to make changes to their production line to incorporate the varnish.

Films coated with the varnish apparently run as smoothly as uncoated films on all machines and integrate well into the printing process, helping to ensure that the print quality remains the same.

Joanna Herbst, Commercial Product Manager Conversion at Schur Flexibles, comments: “Food and consumer safety begin with intelligent packaging solutions. We are the first packaging manufacturer to offer this type of coating to our customers.

“With this solution, we are supporting manufacturers and retailers in their efforts to optimise hygiene and provide enhanced food safety.”
