WHAT ISTHE CORRUGATED? Corrugated fiberboard or "combined board" has two main components: the liner (面纸）and the medium (芯纸). Both are made of a special kind of heavy paper called containerboard (箱板纸). Linerboard (瓦楞纸箱外层的高强箱板纸) is the flat facing that adheres to the medium. The medium is the wavy, fluted paper (楞纸) in between the liners. COMMON BOARD STYLES 常用纸板的种类 Single Face: One medium is glued to one flat sheet of linerboard. 单面纸板：一层芯纸粘接在一层平面箱板纸上。 Single Wall: The medium is between two sheets of linerboard. Also known as Double Face. 单瓦楞纸板：芯纸粘在二层箱板纸之间，也被称为双层纸板。 Dou ble Wall: Threesheets of linerboard with two mediums in between. 双瓦楞纸板：二层芯纸夹在三层面纸之间。 （在中国又被称为五层瓦楞纸板） Triple Wall: Four sheets of linerboard with three mediums in between. 三瓦楞纸板：三层芯纸夹在四层面纸之间。 （在中国又被称为 7 层瓦楞纸板） Flu tes 楞形 Architects have known for thousands of years that an arch （拱） with the proper curve （曲线） is the strongest way to span a given space （跨越一个给定的空间）. The inventors of corrugated fiberboard applied this same principle to paper when they put arches in the corrugated medium（瓦楞芯纸）. 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 combined 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（垫子） to protect the container's contents. The flutes also serve as an insulator ( 绝缘体, 绝热器,保温层）, providing some product pro...
