Dynarex Dyna-Fix Dressing Retention Sheets manufactured by Dynarex are made of soft, flexible non-woven fabric and low-sensitivity adhesive, able to fix dressings and appliances in a desired position. The Dyna-Fix Retention sheet is made of porous, yet water-resistant fabric, ideal for covering an entire wound dressing in a single application. Linerless dressing can facilitate a rapid application without increasing the workload of removing the lining paper.
