CONSTRUCTION OF CELLOPHANE SEALING MACHINE

ABSTRACT: The construction of the cellophane sealing machine was carried out.  The project started with an encompassing review of the various methods of heat sealing film packages.  The machine can be used in sealing both low, medium and high-density cellophane.  The product has a heating element, which converts electrical energy to heat energy, which converts electrical energy to heat energy, which is utilized in the sealing of the cellophane.  It has an efficiency of about 90% with a reasonable degree of accuracy. The major components of the machine included 24 – 30 volts transformer, heating element, electrical cables, plywood, tape (paper, Teflon, black) lever machine, seconds time, micro – switch and on/off indication bulb. The machine was relatively cheap and compares favourably with imported types of the same capacity. The total cost of production amounted to the sum of fifty thousand, one hundred naira only (N50,100.00).
