single wall(three ply) corrugated board-sandwich corrugated cardboard

Intensified sandwich corrugate paper is called “corrugated cardboards of corrugation”. Generally, two, three or five layers of corrugated cardboard are used as outer paper and inner paper (board), between which corrugated cardboard or corrugated paper-tube specially arranged is sandwiched to form wave-type sandwich layer. Reasonable structural design endows the intensified sandwich corrugated board with high strength.

It is measured through testing that the total thickness of the board is 3.2cm (adjustable at will); corrugation density of sandwich layer is 38-40 prism/m; there are five layers of ordinary corrugated cardboard (C prism B prism) as outer layer(ration 780g/m2); three layers of ordinary corrugated cardboard(C Prism) as inner layers (ration 470g/m2); three layers of ordinary corrugated cardboard (B prisma) as sandwich layer(ration 680g/m2 ),with a total ration of 1900-2000g/m2. “Corrugated cardboard of corrugation” is an application of the mechanical principle of multi-azimuth support. It is made of high strength corrugated cardboard, which is deformed and arranged by special technique to form optimal mechanical structure. It can be applied in the manufacture of the packing box of six facades, by forming strong tubular matrix. Its superiority is mainly manifested in its ability to prevent damages to the objects contained in the box, especially for the packaging of large-volume, heavier, fragile and pressure susceptibility items. Moreover, because of its compact structure, seamless, absence of nails, fold ability and forming ability, the overall packaging cost can be reduced by about 30%, and its appearance and integrity are also improved. Therefore, this kind of structure is very applicable for the packaging and transportation of large electrical household appliances and electromechanical equipments.
