Films and bags with visually distinct regions and methods of making the same
One or more implementations of a multi-layer film include a first substantially un-pigmented 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 substantially un-pigmented layer non-continuously bonded is in intimate contact with the second pigmented layer. The visually-distinct areas have the appearance of the pigmented layer. One or more implementations also include methods of making multi-layer films and bags with an unexpected appearance and visually-distinct areas.
