A vacuum packaging apparatus for packaging a product between a plastic film and a backing card comprises a base having a stationary heating hood. A reciprocal table is mounted on the base beneath the hood. Two packaging wells are mounted side by side on the table, each well being dimensioned for holding a backing board on which the product is placed for packaging. The reciprocal table moves laterally on the base so that when one packaging well is in a packaging position under the hood, the other packaging well is not and extends out from beneath the hood. A sealing frame is mounted on the base beneath the hood for holding a sheet of wrapping material and moves vertically between a raised position and a lowered position. In the raised position, the sealing frame is adjacent the heating hood to heat the sheet. In the lowered position the sealing frame is adjacent the packaging well which is in packaging position to place the heated sheet over the board. Vacuum motors are mounted in the base beneath the hood, under the reciprocal table. When the sealing frame is lowered to place the heated sheet over the board in packaging position, a vacuum is drawn against the backing board to seal the heated sheet over the product onto the backing board. A method for packaging using the apparatus is also included.
