Abstract
A preferably plastic film flower sleeve has side edge heat sealed front and back panels tapering inwardly in downward extension providing upper and lower open ends. Each panel has a centralized nonperforated area which increases progressively in transverse width during its downward progression bordered by transversely opposite perforated groups decreasing correspondingly in transverse width during downward progression, the perforated groups also being defined by nonperforated upper and lower end portions. A flower sleeve may be rearwardly rack suspended and forwardly hand suspended during insertion of a flower bunch downwardly therein, the flower bunch stems being maintained forwardly aligned with the progressively increasing nonperforated areas to avoid snagging and the stems ultimately projecting from the sleeve lower end while the increased size flowers of the bunch automatically transversely expand the sleeve perforated groups.
