Do you know the development trend of paper materials?

　　Carton materials used from one layer to seven layers, but the use of multilayer material has a tendency to increase, mainly because used field of the cartons is constantly expanding,requiring more and more high performance requirements.

　　The carton layer can be roughly divided into three class：Single-layer material, 2-3 layers material and multilayers (4-7) material（paper as the basis).

　　Single-layer material:the commonly used cigarette box, cosmetics boxes, and some food boxes,etc.

　　2-3 layers material: the mostly used used wine boxes or alcoholic drink boxes and food boxes.

　　Multilayers material:more and more widely used in drink boxes because of the highly demanded barrier property,such as: Tetra Classic(5-7 layers),Combibloc(7 layers), roof-shaped packing(4 layers).
