摘要： A resealable flap device in the form of a sheet, for applying to or incorporating in packaging, comprises: a base layer (30) of flexible material, and an upper layer (40) of stiff material. The sheet is cut (15) through both layers to outline a flap portion (14), the cut leaving an edge in a hinge region (18), the upper layer being removed behind the line of the hinge region (18). In this way the flexible base layer forms a hinge (18) that is easy to handle and does not spring back, while the stiff upper layer maintains the shape of the flap.

摘要： A resealable flap device in the form of a sheet, for applying to or incorporating in packaging, comprises: a lower layer of flexible material, and an upper layer of stiff material. The sheet is cut through both layers to outline a flap portion, the cut leaving an edge in a hinge region, the upper layer being removed behind the line of the hinge region. In this way the flexible lower layer forms a hinge that is easy to handle and does not spring back, while the stiff upper layer maintains the shape of the flap.
