An opening cutter assembly forms an opening perforation line in a plastic packaging film by rolling the plastic packaging film between the opening cutter assembly and an anvil roll of a rolling mechanism for having an opening perforation line on a plastic packaging film when the plastic packaging film is fed through the rolling mechanism. The opening cutter assembly includes an opening cutter shaft, at least one opening cutter seat, and at least one opening cutter blade. The opening cutter shaft has at least one containing compartment formed. The opening cutter seat is installed in and engaged to the containing compartment of the opening cutter shaft by a cutter seat mounting mechanism. The opening cutter blade is mounted to each opening cutter seat. When the opening cutter blade gets worn out due to long term operation and must be replaced, simply dismounting the cutter seat mounting mechanism allows the opening cutter seat and the opening cutter blade to be removed out of the containing compartment of the opening cutter shaft.
