A film packaging applicator adjustable includes a first tube and a second tube that join with each other. A guidance groove is formed axially on the first tube. Further, at least one side of the guidance groove, several equidistant hemispheric orientation slots that are formed in a radial direction are formed. A neck is formed at the orientation slot near the guidance groove. The second tube opposite to the guidance groove of first tube is formed with a hemispheric positioning block slipping from the guidance groove and then wedging into one orientation slot of the first tube. Thus, the applicator may be adjusted for a required length following the width of a film reel.
