Methods involve packaging butter sticks by adding unformed butter to an extruder, where the extruder shapes the butter into defined dimensions, cutting the extruded butter at a desired length to form butter sticks, cooling the butter sticks, and flow-wrapping the cooled butter sticks within an adhesive film. Systems for packaging butter sticks involve an extruder, a cutting device, a cooling device and a flow-wrapping device, where the extruder shapes unformed butter into defined dimensions, the cutting device slices the extruded butter into butter sticks, the cooling device increases a firmness level of the butter sticks, and the flow-wrapping device packages the butter sticks within a sealed, adhesive film. The extruder, the cutting device, the cooling device and the flow-wrapping device may be connected.

Animal feed tub cover

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&#xb0; F.

Animal feed covers and systems and methods for their production and use

Animal feed tub and cover

Covers for sealing and/or bonding with an exposed surface of an animal feed within a container include a flexible film that conforms to the animal feed and a rigid or semi-rigid layer that allows the cover to be handled by an operator during placement of the cover over the animal feed composition while the composition is at elevated temperatures. The polymer film may include a heat-activated coating that establishes a bond with the animal feed when the feed is at elevated temperatures or when an external heat source is applied to the cover. The heat-activated coating may be flowable at a temperature of at least about 125&#xb0; F. Upon placement of the cover over the animal feed, the film conforms to the exposed surface of the feed and the cover forms a seal with the animal feed as flowable coating reaches a flowable temperature.
