Edge Lift - What is edge lift?
This term refers to the lifting up of one or more of the outer edges of a label from the surface onto which it has been applied. While it can occur on any type of surface, it is most frequently seen when labels are applied onto curved surfaces (for example, when labelling cylindrical containers such as bottles and jars).
Edge lift (or edge curl) occurs when the bond created between an adhesive and a substrate is weaker than the other forces acting on a label. While edge lift can be caused by an issue with the surface of the substrate or the adhesive itself, it is more likely to be the result of the adhesive bond being weaker than the memory of the face material or the result of using an inflexible face material that doesn’t fully conform to the contours of the substrate in the first place.
