A manufacturing process for PVC related disposable gloves, wherein the process comprises the following steps: mixing PVC resin or its mixture and a plasticizer to form a glove formula mixture; making the glove formula mixture into a mixture film; placing two layers of mixture films in parallel to form a glove material film; placing an insulation layer on one side of the glove material film, and applying a beam of electromagnetic waves distributed along a path of a preset contour onto the surface of the glove material film, to make the beam of electromagnetic waves penetrating the glove material film and thus the glove material film is effectively sealed along the path of the preset contour; or heating the glove material film along a path of the preset contour, the heating temperature being equal to or higher than the critical point of heat sealing temperature of the glove material film, and thus the glove material film is effectively heat sealed along the path of the preset contour; applying a pressure on the path of the preset contour so that the two layers of said mixture films of the glove material film are pressed and fused integrally along the path of the preset contour; forming a blade-shaped cut along outer edge of the path of the preset contour, and separating integrally fused part including fused path from the glove material film, and forming an opening at wrist position of the path of the preset contour, so as to form a PVC related disposable glove; the step of heating the glove material film along the path of the preset contour comprising: heating the glove material film on the path of the preset contour to a temperature equal to or higher than the critical point of heat sealing temperature of the glove material film within 2 seconds, keeping the temperature for a period of time between 0.05 seconds and 5.0 seconds before stopping the heating. mixing PVC resin or its mixture and a plasticizer to form a glove formula mixture; making the glove formula mixture into a mixture film; placing two layers of mixture films in parallel to form a glove material film; placing an insulation layer on one side of the glove material film, and applying a beam of electromagnetic waves distributed along a path of a preset contour onto the surface of the glove material film, to make the beam of electromagnetic waves penetrating the glove material film and thus the glove material film is effectively sealed along the path of the preset contour; or heating the glove material film along a path of the preset contour, the heating temperature being equal to or higher than the critical point of heat sealing temperature of the glove material film, and thus the glove material film is effectively heat sealed along the path of the preset contour; applying a pressure on the path of the preset contour so that the two layers of said mixture films of the glove material film are pressed and fused integrally along the path of the preset contour; forming a blade-shaped cut along outer edge of the path of the preset contour, and separating integrally fused part including fused path from the glove material film, and forming an opening at wrist position of the path of the preset contour, so as to form a PVC related disposable glove; the step of heating the glove material film along the path of the preset contour comprising: heating the glove material film on the path of the preset contour to a temperature equal to or higher than the critical point of heat sealing temperature of the glove material film within 2 seconds, keeping the temperature for a period of time between 0.05 seconds and 5.0 seconds before stopping the heating.
