The term 'fly-swatter material' can be summarized as a MESH, which is a four-letter word. MESH is a type of fabric or material that is made up of connected strands of metal, plastic, or other materials. It is often used to make screens, filters, and other items that require a strong yet flexible material. Fly-swatters are typically made from MESH because it allows air to pass through while still being able to catch and trap insects.
