    Abstract: A refining member comprising a refining body with a refining surface comprising first and second refiner bars separated by first and second refiner grooves, respectively. The first refiner bars extend from a radially inward position to a first radially outward position. The second refiner bars extend to a second radially outward position that is nearer to an outermost part of the refining body than the first radially outward position. The second refiner bars have a longitudinal length from about 0.6 cm to about 10 cm. The first and second refiner bars have a respective first and second maximum height extending upward from a floor of a respective, adjacent first or second refiner groove. The second maximum height is at least 0.35 mm less than the first maximum height. The first refiner bars are adapted to refine wood fibers and the second refiner bars are adapted to break up fiber bundles.

    Abstract: A container is provided comprising: first and second side panels, a front panel, a back panel, first and second minor flaps, and first and second major flaps. The first minor flap may be coupled to the first side panel along a lateral edge of the first side panel, and the second minor flap may be coupled to the second side panel along a lateral edge of the second side panel. The first major flap may be coupled to the front panel along a lateral edge of the front panel, and the second major flap coupled to the back panel along a lateral edge of the back panel. The first major flap may comprise a first locking tab capable of engaging with the second major flap when the container is erected and the second major flap may comprise a second locking tab capable of engaging with the first major flap when the container is erected. The first and second minor flaps and the first and second major flaps may be folded inwardly along corresponding fold lines such that the first and second minor flaps are located inwardly from the first and second major flaps.

    Abstract: A leak proof container and a method of forming the container from a blank. The blank includes a bottom panel, first and second side panels connected to the bottom panel at opposing lateral edges, and first and second end portions located at opposing longitudinal ends of the blank. Each end portion includes an inner end panel connected to the bottom panel, an outer end panel connected to the inner end panel, and first and second corner panels forming gussets connected to a respective one of the first and second side panels and connected to the inner end panel. An adhesive area is located on one side of the blank and comprises at least a portion on each of the outer end panel and the inner end panel. The adhesive area adheres the gussets to the inner end panel and to the outer end panel.

    Abstract: Treated pulp sheets comprising cellulose pulp fibers treated with a densifying agent and having a relatively low moisture content. In certain embodiments, the treated pulp sheets are used to produce fiberized pulp having low knot content, while maintaining density and softness properties usually associated with similarly treated pulp that is fiberized at higher moisture content. Methods of making fiberized pulp from the treated pulp sheets, as well as products comprising the treated pulp sheets or fiberized pulp from the treated pulp sheets, are also provided.
