A flexible base material (35) or substrate has a stiffening treatment (40) such as an aqueous coating, ink coating, other coating, spot lamination or varnish applied to it by spraying, laying as film or printing. The stiffening treatment may, for example, provide a stiffer composite material. The hinge (30) is formed by not applying the treatment, by applying a lesser (e.g. thinner) treatment or by applying a different treatment to a region of the base material. That region then forms a strip or band of untreated, less treated or differently-treated base material that is more flexible than the treated, more treated or differently-treated base material in other regions. The more flexible region is therefore apt to be used as a hinge about which the article may be folded. |
