What is a butterfly pouch? How is it different than a regular pouch?
Butterfly pouches are formed by folding a piece of film in half. While there is a fold, there are no sealed edges, resulting in a border-free document. This type of pouch is intended for laser-ready plastic (teslins) and other non-paper inserts. Regular pouches are different because they are two sheets of film held together by 1/8″ seal on the leading edge. This seal makes it easy to align the insert. Regular pouches are always larger than the items being laminated to ensure there are sealed edges on all four sides. This creates a moisture-proof border.
