Perforierten

Perforierten is the inflected form of the German adjective derived from the verb perforieren, meaning having perforations or holes. It is used to describe objects, materials, or tissues that have been perforated, i.e., pierced or punched with holes. The base participle is perforiert; the ending changes with gender, number, and article. For example, feminine singular: eine perforierte Folie; neuter singular: ein perforiertes Loch; masculine singular: ein perforierter Schlauch; plural with a definite article: die perforierten Löcher.

In practice, perforated items are common in engineering, manufacturing, and design. Perforierte Folien, Bleche, oder Filtermedien allow drainage, airflow, filtration, or acoustic modification while reducing material weight. Perforationen are often arranged in regular patterns to achieve specific mechanical or functional properties, such as stiffness, permeability, or visual texture. The term is also used in filtration and acoustics to describe products whose performance relies on controlled hole size and spacing.

In a medical context, perforationen refers to the creation or presence of a hole in a tissue or organ. A perforation of the gastrointestinal tract, for example, denotes a pathological hole and is typically a medical emergency requiring prompt treatment. In pathology reports, the adjective perforiert may describe tissue that has been intentionally perforated for diagnostic purposes or that has developed a perforation due to disease.

Related terms include Perforation (the noun for the act or result of perforating) and durchlöchert, which is a synonym used in colloquial language. Overall, perforierten functions as a descriptive adjective indicating the presence of perforations in a wide range of contexts.
