The reason of influencing the compounding speed of packaging bag custom printing manufacturers

The closing speed is determined by the rotation speed (extrusion speed) of the extruder, which directly determines the hum degree and viscosity fastness of extrusion or coating. The faster the compounding speed is, the thinner the extrusion or coating layer is, and the lower the viscosity is, and vice versa. Generally speaking, the composite speed is generally controlled at 150 m/min to F, and the mud degree of U coating is about 50/in. Sometimes, in order to improve the composite speed without reducing the composite fastness, it is often used to add tackifier, substrate coating adhesive or AC to increase the composite fastness; (force method, perform rapid extrusion compounding or extrusion coating.
