Low SIT temperature heat-sealing matt compound is suitable for the preparation of high-quality low-temperature heat-sealed BOPP matting film. The low SIT temperature matt compound has good affinity with the core layer of PP, which will form a uniform rough surface with appropriate roughness on the surface of the film with Haze higher than 75%, and has a relatively low heat-sealing temperature, which can reach as low as 95℃. This kind of matt compound is usually used in: matte paper-plastic composite film, matte tape substrate film, matte packaging film and various high-grade composite packaging.
