Abstract: Foldable apparatus can comprise a first portion comprising a first edge surface defined between a first surface area and a second surface area opposite the first surface area. Foldable apparatus can comprise a second portion comprising a second edge surface defined between a third surface area and a fourth surface area opposite the third surface area. A polymer-based portion can be positioned between the first blunted edge surface and the second blunted edge surface. In some embodiments, the polymer-based portion can comprise a polymer thickness of about 50 micrometers or less measured from the second surface area and/or the first surface area. In some embodiments, the first edge surface and/or the second edge surface can comprise a blunted edge surface. In some embodiments, a coating can be disposed over the first portion, the second portion and the polymer-based portion.
