In some embodiments, a label holder for retaining an electronic product label and detachably coupling to a product container includes rear panel, a top panel and a bottom panel each movably attached to the rear panel and extending in a forward direction relative to the rear panel, and at least one container-gripping panel attached to the rear panel and extending from the rear panel. The rear panel, the top panel, and the bottom panel together define a channel therebetween configured to slidably receive and retain an electronic product label. The container-gripping panel includes a plurality of projections extending therefrom and configured to grip at least one wall of the product container to detachably couple the label holder to the product container. Methods of detachably attaching the label holder to the product container and methods of uncoupling the label holder from the product container are also described.
