Abstract: Embodiments of the present disclosure provide a modular sealing apparatus for a vacuum packaging machine. The modular sealing apparatus includes a cap module including a central portion. The central portion locates thereupon a heating wire. The heating wire is configured to heat up when supplied with electrical power through an electrical power unit. The modular sealing apparatus further includes an actuation box, the cap module detachably coupled to the actuation box. The actuation box is located under the cap module. Furthermore, the actuation box includes an electrical drive unit configured to cause the cap module to move upwards and against a counterpart, by activating an actuation member. The modular sealing apparatus also includes an interface module coupled to the actuation box. The interface module is configured to detachably fasten the actuation box to the vacuum packaging machine, and enable supply of the electrical power to the actuation box.
