e medium (芯紙). Both are made of a special kind of heavy paper called containerboard (箱板紙). Linerboard (瓦楞紙箱外層的高強(qiáng)箱板紙) is the flat facing that adheres to the medium. The medium is the wavy, fluted paper (楞紙) in between the liners. COMMON BOARD STYLES 常用紙板的種類 A、Single Face: One medium is glued to one flat sheet of linerboard. 單面紙板:一層芯紙粘接在一層平面箱板紙上。 C、Double Wall: Threesheets of linerboard with two mediums in between. 雙瓦楞紙板:二層芯紙夾在三層面紙之間。(在中國(guó)又被稱為7層瓦楞紙板) Flutes 楞形 Architects have known for thousands of years that an arch (拱) with the proper curve (曲線) is the strongest way to span a given space (跨越一個(gè)給定的空間). The inventors of corrugated fiberboard applied this same principle to paper when they put arches in the corrugated medium(瓦楞芯紙). These arches are known as flutes (楞)and when anchored to the linerboard with adhesive, they resist bending and pressure from all directions. When a piece of bined board is placed on its end, the arches form rigid columns, capable of supporting a great deal of weight. When pressure is applied to the side of the board, the space in between the flutes acts as a cushion(墊子) to protect the containe
