Modular sealing machine

A modular sealing system for sealing plastic wrap around an item, the system comprising:

• a base unit;
• electrical components in the base unit for controlling and powering the system:
• a first electrically powered modular hot sealing frame for sealing a first layer of plastic wrap and a second layer of plastic together, the first hot sealing frame including a first elongated heated portion extending in a first direction and a second elongated heated portion extending in a second direction different from the first direction wherein the first and second elongated heated portions contact only the first layer of plastic wrap so that the first layer of plastic wrap melts to the second layer of plastic wrap, the hot sealing frame being detachably mountable to the base unit and detachably electrically connectable to the electrical components, wherein the first electrically powered modular hot sealing frame is interchangeable with a second electrically powered modular hot sealing frame including two elongated heated portions each extending in a direction different from the other for sealing plastic wrap together, the second electrically powered modular hot sealing frame being detachably mountable to the base unit and detachably electrically connectable to the electrical components, the second electrically powered modular hot sealing frame having a different configuration or functioning in a different manner from the first electrically powered modular hot sealing frame.
