ABSTRACT:
A high impact strength protective seal for packaging reels of magnetic tape, cinematographic film or the like and for storing them in a suspension type storage cabinet has been developed. The seal is of a single piece design, i.e., a molded unitary locking mechanism and annular band, as opposed to the more conventional two piece design of sealing rings for tape reels of the prior art. The protective seal is prepared by injection molding the seal flat from a thermoplastic material. The design of the seal and its locking mechanism allows for the seal to be adjustable in order to accommodate variations in the take up on a particular reel or in variations from reel to reel.
