Method and apparatus for assessment of adhesion of labels

摘要

An apparatus and method for assessing adhesion of labels applied to a bottle. A label adhered to the outer surface of the bottle is split vertically to form a leading end and trailing end of the label. The bottle may be secured to a support structure and the trailing end of the bottle may be secured to a weighted structure. The bottle is suspended in a heated chamber via the support structure until the adhesive fails, causing the weighted clamp to fall within the chamber. An elapsed time to failure is determined for the bottle and compared to a benchmark time and/or metric as an indicator of how the adhesive is likely to perform during shipping and/or storing the bottle.

1. A method for testing adhesion of a label to a bottle, the method comprising:
filling a bottle comprising a label adhered to an outside surface of the bottle with liquid that has a temperature greater than the temperature of the bottle; slitting the label adhered to the outside surface of the bottle to form a leading end and a trailing end of the label at the slit; attaching the bottle to a support structure within a heated chamber; suspending a weight from the trailing edge such that it hangs below the support structure; and determining an elapsed time before the label disengages from the bottle.
