Straight corrugation
Diagonal corrugated board
Grid corrugation
Straight corrugation, also known as vertical corrugation, refers to a corrugated board structure where the ridge lines of the corrugations run parallel to the long edge of the board, and the crease lines align with the direction of the corrugations.
> Corrugation direction: The corrugations extend vertically (along the long side of the carton) to form upright supports.
> Crease direction: Folding creases follow the same direction as the corrugations to prevent rupture of the corrugated ridges.
> Flute options: Flutes A, C, B and E are commonly available; Flutes A and C are preferred for straight corrugation thanks to their higher flute height and superior cushioning performance.
> High compressive resistance: The vertical supporting structure delivers high edge crush strength and better load-bearing capacity than cross corrugation.
> Excellent rigidity: It resists bending along the corrugation direction and maintains stable performance under vertical load.
> Easy folding: Creases aligned with the corrugations enable neat folding without ridge breakage, making it ideal for automatic carton gluing.
> Anisotropic property: High strength along the corrugation direction yet weaker strength perpendicular to it; the load-bearing direction must be considered during structural design.
Diagonal corrugation refers to a special corrugated board structure in which the ridge lines of corrugations form an included angle of 15°–75° (commonly 30°–45°) with the long edge or side edge of the board, instead of being parallel or perpendicular. Its core advantage lies in balanced multi-directional stress bearing and high deformation resistance.
> Corrugation direction: Corrugations extend diagonally, with the included angle of 30°–45° relative to the side edge being the most widely adopted.
> Multi-layer combination: It is often laminated alternately with straight or transverse corrugation (e.g., X-shaped cross lamination) for more uniform strength in all directions.
> Flute types: Flutes A/C are selected for cushioning purposes, while B/E flutes are used for rigidity, catering to diverse load-bearing requirements.
> Isotropic property: Its strength along and perpendicular to the corrugation direction is nearly equal, eliminating the drawback of "high strength along the flute but low strength crosswise" found in straight corrugation.
> Outstanding bending resistance: The diagonal supporting structure disperses stress, resisting warping and cracking during handling and stacking.
> Stable cushioning effect: Diagonal corrugations absorb energy evenly and deliver better shock absorption than straight corrugation, providing reliable protection for fragile goods.
> Balanced rigidity: It balances flat compression resistance and edge crush strength, suitable for application scenarios with complex stress conditions.
Grid corrugation, also known as cross corrugation, is a special type of corrugated board manufactured by laminating two layers of corrugated medium oriented lengthwise and crosswise at a 90° orthogonal angle. The flute lines intersect perpendicularly to form a grid/cross-shaped stress-bearing network, featuring balanced strength in all directions plus exceptional flat compression and bending resistance.
> Medium structure: Two single-wall single-faced corrugated layers are bonded in a lengthwise-crosswise orthogonal layout (90°). An intermediate liner paper can be inserted to form a 4-layer or 5-layer composite structure. The orthogonally arranged flutes build up a grid support network.
> Flute combinations: Flutes A/C are commonly used for cushioning and load bearing, while B/E flutes deliver rigidity and excellent printability. Mixed flute combinations (e.g., flute A lengthwise and flute B crosswise) are also available.
> Visual features: Crossed vertical and horizontal flutes create a distinct grid texture on the surface; the board is thick, stiff and firm overall.
> Isotropic performance: Near identical strength in both lengthwise and crosswise directions, completely eliminating the defect of uneven strength (strong along flutes, weak across flutes) in straight corrugation and the angle limitation of diagonal corrugation.
> Superior flat compression resistance: The grid support structure distributes pressure evenly, achieving flat crush strength 2 to 3 times that of conventional double-wall corrugated board, with outstanding dent resistance and stacking durability.
> Exceptional bending resistance: The intersecting dual-direction flutes form a lattice truss structure, delivering powerful resistance to bending and flexing, and effectively preventing warping and cracking.
> Reliable cushioning performance: The double orthogonal flute layers absorb impact energy uniformly, offering better shock absorption than straight or transverse corrugation, making it ideal for protecting precision instruments and fragile goods.
