There are some basic components for corrugation.
These basics include:
- The central fluted component of corrugate is called medium .
- Mediums, like liners are identified by basis weight. Common medium basis weights are 26, 30, 33, 36, and 40.
- The flutes in medium form arched structures, when fixed to the liners give the board it’s thickness or caliper.
- A starch and water based adhesive is used to bond liners to the medium.
- Additives can control characteristics, regulate viscosity and lend varying amounts of water resistance to the bond.
- Flutes in a vertical mode form columns which give corrugate it’s great strength to weight advantage.
