Types of Corrugated Materials

Singleface

Single Faced fibreboard is constructed by gluing a flat sheet of linerboard to a sheet of corrugated material which has been passed through a single facer, thus forming it into a series of arches. This ensures that the corrugations will be firm and will not stretch or flatten.




Singlewall, Doublewall, & Triplewall

Singlewall corrugated fibreboard consists of two flat facings and one corrugated member combined in the sequence that follows: a facing, a corrugated member, and another facing.


Doublewall corrugated fibreboard consists of three flat facings and two corrugated members combined in the sequence that follows: a facing, a corrugated member, a centered facing, a corrugated member, and a facing.


Triplewall corrugated fibreboard consists of seven sheets of paperboard combined in the following sequence: a facing, a corrugated member, an inner facing, a corrugated member, an inner facing, a corrugated member, and a facing.
