Abstract
A multiple compartment banding sleeve is proposed in the form of a cylindrical band of heat shrinkable material, e.g., PVC, which is divided into two or more envelopes by longitudinal seams. The sleeve may be used to wrap, protect and display a grouping of similar or dissimilar items.
Claims5
A packaging sleeve comprising
- (a) a pair of opposed walls of non-elastic, heat shrinkable thermoplastic sheet material hinged at opposite ends to form a flattened tube having a predetermined center line;
- (b) a vertical welded seam parallel to and spaced from said center line joining said walls intermediate said ends;
- (c) said vertical seam dividing said sleeve into two separate envelopes of unequal size;
- and
- (d) said separate envelopes being adapted to be independently shrunk about two adjacent dissimilar objects with said seam disposed as an axis of interfacing to retain said objects in a predetermined generally abutting relationship.
