A. Schulman expands range of Polybatch antibacterial and antimicrobial masterbatches

A. Schulman is expanding the range of its speciality antibacterial and antimicrobial masterbatch solutions to meet a wider variety of application needs in the packaging, consumer products and medical markets.

The company's Polybatch ABACT antibacterial masterbatches inhibit the growth of microorganisms that can cause odours, discolouration, the formation of mildew, or deterioration in the physical properties of plastics. Its Polybatch AMIC antimicrobial masterbatches protect against bacteria and fungus. The company utilises silver ion technologies in its antibacterial and antimicrobial masterbatches.

A. Schulman provides global support for these products in the Americas, Europe and Asia-Pacific regions, where it works with processors and product manufacturers on application development; product selection, testing and validation; manufacturability; and regulatory support. Because of its expanded range of products and abilities in custom compounding, the company is able to serve a wide variety of markets, including food and flexible packaging, household appliances and other durable goods, pharmaceuticals, medical equipment, and building materials.

Among the company's range of solutions are:

Four grades of standard antibacterial products, some of which have been found to reduce bacteria by more than 99.99 %
New grades of high-performance antibacterials for spunbond nonwoven fabrics and thin layer applications (e. g., biaxially oriented or BOPP film)
Antimicrobials that have been tested to have a bacteria and fungus survival rate of 0.8 - 0.1 % in polyethylene film
