A tube of plastic material is cut at a bag length interval from a free end to define an open mouth. The free end is sealed to form a bag and a reclosable fastener strip is affixed to the open mouth after the tube is cut. Prior to affixing the reclosable fastener strip, but after the tube section is cut, the bag is moved away from the remainder of the tube. The side edges of the bag adjacent to the open mouth are slit and the slits and reclosable fastener strip are joined after the reclosable fastener strip is positioned in the slits. The bag may be filled after the free end of the tube is sealed but before cutting the bag length interval from the tube.
