Label assembly and method of manufacturing

Abstract

A label assembly comprising a releasable portion which may be used as an in-store coupon constructed of a base stock having a first and second film layer having a controlled interfacial bond therebetween which will retain the film layers in integral relationship during handling or the like, but will also allow the easy separation between the film layers when desired. The controlled interfacial bond may be termed as 'controlled adhesion' which is obtained by co-extruding two dissimilar polymer layers having a controlled affinity therebetween. A pressure sensitive adhesive layer is laminated to the second film layer and is provided with a release liner for the easy handling thereof. A face stock comprising a top sheet forming an in-store coupon, for example, is then adhered to the first film layer of the base stock structure to complete the label assembly. The releasable portion may be removed from the label assembly by breaking the controlled interfacial bond between the two film layers leaving no tacky or sticky surfaces behind, and allowing a clear, unobstructed view of the primary label graphics and coupon or other information on the releasable portion. The label assembly may be manufactured in an easy and cost effective manner and is suitable for various uses such as providing a controlled surface for reclosing a product container or as a tamper evident container closure assembly.
