A strap pressing device for a strap packing apparatus includes a strap presser, an eccentric shaft, and a spring. The eccentric shaft consists of a first shaft and a second shaft eccentrically connected to the first shaft and received in an oval hole of the strap presser. The first shaft is pivotally connected to a side of the base. A spring is fitted around the second shaft in the oval hole, so the strap presser may be pressed down to press a strap closely contact the upper surface of the base, and also moved bias by movement of the second shaft when the first shaft is moved by a lever so that the strap presser may be moved bias to rise up quickly to leave the upper surface of the base so as to prevent a curved bottom surface of the strap presser from frictionally sliding on the strap to give scar on it.
