PacStar-HD utilizes the latest Structured Warp forming technology in conjunction with the most advanced Wear Resistant Yarn in the world- EcoLife. This means a very clean running, efficient, stable forming fabric structure that gives maximum life potential while providing optimum drainage capacity and low running void volume. Formation, Test, Cleanliness, and Sheet Solids are the result! Two forming surface variations, plain weave and 3-shed, offer options to make sure the forming process can meet the demands of high performance packaging machines. High headbox flows means a better formed sheet and the highest possible test results.
