Corrugated fiberboard
paper-based material consisting of a fluted corrugated sheet and one or two flat linerboards
Corrugated fiberboard, corrugated cardboard, or corrugate is a type of paper packaging material consisting of a fluted corrugated sheet and one or two flat linerboards. It is used for making corrugated boxes. Corrugated (also called pleated) paper was patented in England in 1856, but corrugated boxboard for use in shipping material was not patented until 1871. Several properties and characteristics can be measured for corrugated board, including moisture content and burst strength. Corrugated board is manufactured on large high-precision machinery lines called corrugators. Packaging engineers design corrugated boxes to meet the particular needs of the product being shipped. Old corrugated containers (OCC) are an excellent source of fiber for recycling.

This brief starts where responsible research should: with the source description of “Corrugated fiberboard” as paper-based material consisting of a fluted corrugated sheet and one or two flat linerboards. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as paper-based material consisting of a fluted corrugated sheet and one or two flat linerboards. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Aug 28, 2026. The linked authority identifier is Q7463524. The Library of Congress control number is sh85033055. None of the 1 selected statements returned an explicit reference. The first chronological checks are 1856 and 1871.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
