Umschlags

Umschlags is a German term that refers to a cover, wrapper, or outer layer that surrounds another object. The concept is used in several everyday and technical contexts and encompasses different materials and designs depending on purpose.

In postal use, a Umschlag denotes an envelope or mail wrapper. Such Umschläge are typically made from paper and sized to standard formats like DIN A4 or A5. They may be plain or printed with logos and sender/recipient information, and often include a flap for sealing. Security features or tamper-evident elements can be added for additional protection of contents.

In publishing, the Umschlag describes the dust jacket or wraparound cover of a book. This protective sleeve covers the front and back boards and may extend to the spine. It serves both protective and marketing functions, including the presentation of bibliographic data, summaries, and artwork. In some usages, the term can refer to the book’s outer cover in general, particularly the dust jacket.

Beyond mail and books, Umschläge are used as protective sleeves for documents, photographs, or archival materials. These sleeves can be made from paper, plastic, or archival-safe materials and come in various sizes. Features may include acid-free composition, moisture resistance, or resealable closures to protect fragile items.

Etymologically, Umschlag combines um- “around” with Schlag, conveying the sense of something that wraps or covers around an object. The term is used across contexts to describe a protective or enclosing layer that can be removed or replaced.
