As the name suggests, a pressure-sensitive paper is unique and reacts when pressure is applied. A layer of pressure-sensitive coating is added to a sheet of regular paper to produce this specialized paper. Different materials like latex, acrylic, and silicone are used in creating the layer.
Primarily utilized in various pressure-sensitive applications such as labels, tape, and decals, this paper undergoes a process where the substrate is coated with an adhesive sensitive to pressure – commonly an acrylic adhesive known for its responsiveness. The availability of different weights, textures, and colors allows for versatility in usage.
When pressure is exerted on the surface of the pressure-sensitive paper, the adhesive becomes activated. It forms a strong bond between the object it adheres to and itself. Its ease of use and reliable bonding capabilities make it highly suitable for diverse applications requiring this property.
One can find Pressure-sensitive papers in many sizes, colors, and weights, along with compatibility with various printing methods like offset printing or digital printing. Different finishes, such as matte or glossy options, and UV coating varieties are also available.
The application process typically involves applying the pressure-sensitive coating on one or both sides using a roll-coating technique followed by drying and precision cutting.
Notably, pressure-sensitive paper is essential in blood pressure measurement within medical settings. It facilitates doctors and nurses in taking accurate readings while also serving as a valuable material for research purposes focused on studying blood-pressure dynamics within the human body.
