Paperboard carton has the properties of foldability and rigidity. GH Pack uses only folding-box grade paperboard in manufacturing our cartons to ensure the box is creased and folded without fracture. High quality paperboard also reduces deformation. The substrates we have include art paper with C1S and C2S, grey board with one side and both side in white, etc. The gauges range from 210gsm (i.e. 10pt) to 450gsm (i.e. 26pt). This covers most of the packaging demand. If you are looking for higher or lower gauge, just feel free to talk to us.
