One or more implementations of a multi-layer film include a first layer non-continuously bonded to a second pigmented layer. The multi-layer film includes an unexpected appearance differing from the appearance of the pigmented layer. In one or more embodiments, the multi-layer film includes a metallic appearance despite the pigmented layer being devoid of metallic pigment. The multi-layer film also includes areas that are visually distinct from areas of the film with the unexpected appearance. The visually-distinct areas comprise areas in which the first layer non-continuously is in intimate contact with the second pigmented layer. The visually-distinct areas have the appearance of the pigmented layer or another appearance. One or more implementations also include methods of making multi-layer films and bags with an unexpected appearance and visually-distinct areas.

An apparatus for introducing transverse trapezoidal corrugations into a traveling web is provided, and includes a plurality of corrugating rollers for imparting corrugations to the web. In disclosed embodiments four such rollers are provided in a roller train defining respective first, second and third nips therebetween, wherein the teeth of the first and second rollers have rounded distal faces and those of the third and fourth rollers have flattened distal faces. Methods of yielding a trapezoidal corrugated web also are disclosed.

A system and method for producing a board product made from paper products that have embossed medium that features an improved structural profile. The improved structural profile may include a triangular flute pattern wherein each flute may exhibit a first linear leg support and a second linear leg support that each support a center apex structure. The apex may have a substantially flat portion that is configured to engage a facing. As such, the board product may further include one or more facings that are adhesively coupled to the embossed medium. Further, the apex of each triangle may also have a groove or channel for receiving an adhesive in a continuous and uniform manner.

A composite panel includes a sheet having layers. At least two of the layers are kraft paper. The layers re stacked on each other and adhered together with a resin. The sheet is corrugated with alternating peaks and valleys disposed sequentially along an axis of the sheet. Each peak has a plateau and each valley has a base. Each of the plateaus and the bases lies in a plane being substantially parallel to the axis of the one sheet.

Tip bonded formed laminates, and methods for making tip bonded formed laminates, are made from multiple layers of formed substrates made from films which are bonded together at the tips of their formed protrusions. Tip bonded laminates can be designed with greater resistance to bending, improved resilience to compression, and can be patterned for directionally oriented responses to tensile loads. Also, tip bonded formed laminates made from multiple layers of formed substrates can use their layered structure to provide better aesthetics as well as better physical properties such as improved puncture resistance. Tip bonded formed laminates can be configured with thicker portions and designed patterns, which are appealing to consumers. A tip bonded formed laminate can be made from two or more formed substrates and can be used instead of a single, thick, unformed, substrate, so the laminate can use about the same amount of material, while still providing surprising functional benefits. Tip bonded formed laminates can provide these benefits without relying on more expensive polymers and/or high concentrations of additives and offer significant improvements at a reasonable cost, when compared with unformed, single layer substrates.
