Abstract

A tamper-evident shrink sleeve (9) is described to be shrunk around at least a mouth portion of a container and a closure member closing the mouth portion so as to provide a seal. The shrink sleeve (9) comprises breaking means (17) and a tab (15) arranged adjacent the breaking means (17) for tearing the shrink sleeve (9) as defined by the breaking means (17). The shrink sleeve (9) is formed from heat-shrinkable sheet material having a first end portion (25) and a second end portion (29) overlying the first end portion (25) and being bonded or adhered to the first end portion (25) at a bonding section (27) to define an annularly closed sleeve portion (11) of the shrink sleeve (9). The tab (15) is formed by at least one of the end portions (25, 29) projecting outwardly from the sleeve portion (11). The tab (15) further comprises at least one layer (31 ) of a non-heat-shrinkable or essentially non-heat-shrinkable sheet material overlying at least a partial section of the at least one end portion (29) and prevents shrinking of the end portion.

Abstract

A stretch film sleeve label applicator for separating a stretchable sleeve label from a web of such labels and applying the label to an item, such as a container, is disclosed. The applicator is particularly useful for applying high stretch labels to highly contoured containers. The applicator is configured to receive a series of labels in an elongated, continuous web of flat, 2-ply sleeve labels, open the continuous sleeve of labels, separate an individual label from a next successive label, stretch the label to permit its application to an item to be labeled, such as a container, and apply the label in an accurate and precise location on the container. The applicator comprises three primary components: a label feeding assembly, a label separating assembly and a label stretching assembly. Various embodiments of the label feeding assembly, label separating assembly and label stretching assembly are disclosed.
