Ahlstrom- Munksjö’s TenderGuard, including BioBased and BioFilter fabrics, is designed for civil use and source control for infectious disease. The technology is biodegradable and compostable under controlled conditions according to European Norm EN13432. TenderGuard Natural and Smooth fabrics are designed for medical facemasks. They are protective, hypoallergenic, and environmentally friendly.
TenderGuard BioBased can be used as an inner or outer coverstock layer of a civil facemask. It is highly breathable, biocompatible, and non-irritating, so it’s gentle on the skin and comfortable to wear for long durations. Mainly comprised of polylactic acid, which is a biopolymer made from sustainable and renewable sources, TenderGuard BioBased is an alternative to synthetic spunbond material.
TenderGuard BioFilter is a sustainable filter media that can be used as a single layer or combined as a double layer for higher filtration performance in a barrier face covering. This unique fabric is made up of a special blend of cellulosic and cellulose-based manmade fibers making the filter media 100% bio-based.
The TenderGuard product portfolio consists of protective fabrics applicable for medical use as well. TenderGuard Natural is a wetlaid fabric that can be used as the inner or outer layer of a face mask. It is environmentally friendly, and the hypoallergic inner layer makes it super soft for the wearer. With both layers together, TenderGuard Natural achieves nearly 50% Bacterial Filtration Efficiency, which is remarkable without a filtration layer included.
TenderGuard Smooth consists of bicomponent spunbond fabrics that are made with a proprietary technology that minimizes raised fibers. This creates a smooth surface to help eliminate any skin irritation, which is essential when it comes to a face mask. TenderGuard Smooth is hypoallergenic, so it is gentler on the skin, making it ideal to wear for long durations.
