 Advantages of Structured Paper How This Patented Technology Works Revolutionary Papermaking Advantages of Structured Paper This revolutionary change in the papermaking process yields an array of product properties that further extend P&G's tissue and towel product superiority. The absorbent capacity, strength, flexibility, softness, and thickness of structured tissues, and towels make usage more convenient, faster, and comfortable. In research, consumers rate P&G products significantly above those of competitors. Through its use of proprietary technology, P&G's development of structured tissues and towels has become the benchmark for the entire industry. How This Patented Technology Works A woven screen of fabric forms a belt (shown) with a patterned surface that becomes the template for continuous sheet molding when mounted on a paper machine. Through the molding and drying process, structured tissues and towels become more absorbent per gram of fiber and have increased sheet flexibility. 
Revolutionary Papermaking
In 1985, P&G was awarded patents for another revolutionary papermaking process that non-P&G scientists had earlier not deemed impossible. The development of a process to form even more highly structured tissues and towels further extended the three-dimensional nature of paper sheets. The new method delivered higher-quality, cost-effective products that used even fewer raw materials. The process involves casting and selective ultraviolet curing of a liquid photopolymer film onto a woven screen of fabric. The screen of fabric forms a loop or belt with a patterned surface that is used as the template for continuous sheet molding when mounted on a paper machine. A typical belt is several yards wide, more than 100 feet long, and must withstand damaging chemical and physical forces. With this process, the flexibility to provide patterned surfaces is essentially limitless. Not only does the process produce a better product, it represents a dramatic advancement in the science of photopolymer chemistry. P&G's production facility for these belts has the world's largest and most precise continuous photopolymer casting line. |
