Abstract

Methods of covering an animal feed product involve depositing in an open end of a container an animal feed. Placing a cover on an exposed surface of the feed at the open end of the container, where the cover includes a flowable coating arranged on one side of a flexible film and a rigid or semi-rigid layer bound to an opposite side of the film. The exposed surface of the feed comprises irregular surface structures due to feed components positioned at the exposed surface. A central portion of the flexible film of the placed cover conforms to the irregular surface structures at the exposed surface of the feed upon the flowable coating reaching a temperature of at least about 125° F.
