Kraft paper tape, with its unique material and performance, stands out among many tape products, especially in the fields of packaging, fixing, protection, etc. It plays an irreplaceable role. Among them, high viscosity is one of the important characteristics of kraft paper tape, and the realization of this characteristic is inseparable from its unique manufacturing materials and processes.
The high viscosity of kraft paper tape mainly comes from its carefully selected adhesive and special coating process. Adhesive is the key to the viscosity of kraft paper tape, which determines the adhesion and durability of the tape. In the manufacturing process of kraft paper tape, high-performance acrylic glue or natural rubber is usually selected as adhesive. These adhesives have excellent adhesion and stability, and can maintain stable viscosity in various environments.
In addition to the selection of adhesives, the coating process is also an important factor in achieving high viscosity of kraft paper tape. During the manufacturing process, the adhesive is evenly coated on the kraft paper substrate. This step requires precise control of the coating amount and uniformity of the adhesive to ensure that the tape can fully contact the surface of the adherend when pasting to form a strong adhesion. In order to achieve high viscosity, the coating process usually uses precision coating equipment and advanced control technology to ensure uniform coating and precise control of the adhesive.
In addition, the choice of substrate for kraft paper tape also has a certain impact on its high viscosity characteristics. High-quality kraft paper substrate has excellent strength and toughness, and can withstand large tensile and shear forces, thereby maintaining the overall stability and adhesion of the tape. At the same time, the surface treatment of the kraft paper substrate will also affect its bonding effect with the adhesive, which in turn affects the viscosity of the tape.
It is worth noting that the high viscosity of kraft paper tape is not constant. During use, the viscosity of the tape may change due to factors such as environmental humidity and temperature. Therefore, when using kraft paper tape, it is necessary to pay attention to the temperature and humidity control of the storage environment to ensure that the tape can maintain stable viscosity.
In summary, the high viscosity of kraft paper tape is the result of the combined effect of multiple factors such as careful selection of adhesives, special coating processes, and high-quality substrate selection. These factors are interrelated and influence each other, and together determine the adhesion and durability of kraft paper tape during the pasting process.
