Corrugated Cardboard Packaging
We offer one of the most comprehensive portfolios of corrugated packaging solutions in UNITED ARAB EMIRATES and Middle East Countries. Our corrugated fiberboard, are used in a wide variety of industrial packaging applications.
Corrugated fiberboard or cardboard (as it's sometimes referred) is a paper-based material that consists of a fluted corrugated sheet and one or two flat linerboards. The smooth, flat paper that sandwiches the interior fluting is the linerboard. The fluted paper (or medium as it is sometimes referred) is joined to the flat linerboard with an adhesive to form the corrugated fiberboard.
Two design factors impact the weight, strength, qualities and characteristics of corrugated fiberboard: fluting and wall construction.
Wall construction is the most straightforward design factor. Corrugated cardboard walls are manufactured in single, double, and even triple-wall thicknesses. The more layers in the cardboard wall, the greater the strength.
The inventors of corrugated board applied similar science to paper as ancient architects did to buildings. When trying to uphold heavy loads, strength is unsurpassed when using an arch. Generally the larger flute profiles give greater vertical strength and cushioning. The smaller flutes help enhance graphic capabilities while providing greater structural integrity. By experimenting with flute profiles, designers can vary compression strength, cushioning strength and thickness.
Corrugated comes in different wall construction
Single-wall corrugated boxes have a wide range of material strength, which is measured in terms of the Edge Crush Test (ECT). The ECT test identifies the strength of the corrugated cardboard per square inch when crushed. The ability of the assembled box to withstand weight before bursting is measured with the Mullen Bursting Test. Single-wall corrugated boxes start at 23 ECT and range up to 55 ECT. Most single-wall corrugated boxes come in 200# to 275# bursting test strength. Very lightweight single-wall boxes will have a maximum box weight of 9 KG., a bursting test weight of 57 KG., and an ECT of 10.43 KG per square inch.
Double-wall cardboard is automatically stronger and more resistant to crushing than single-wall cardboard. Heavier and less flexible than single-wall corrugated material, double-wall corrugated cardboard is designed to accommodate heavier contents for shipping and storage. Double-wall corrugated cardboard strengths range from 42 ECT to 82 ECT. Double-wall corrugated boxes have minimum bursting test weights starting at 91 KG and going up to 272 KG
Triple-wall corrugated boxes contain three corrugated mediums and four linerboard facings. This 7-ply construction is used where large container sizes are involved, such as pallet packs. Triple-wall corrugated boxes can hold significantly more weight, ranging from 109 to 136 KG, with 67 to 112 ECT. Triple-wall corrugated boxes are the heaviest type, and can hold significantly more weight, ranging from 109 to 136 KG, with 67 to 112 ECT.
Fluting is the element of corrugated cardboard that contributes to material strength for stacking, resistance to crushing, or suitability for other uses, such as graphic reproduction. The types of fluting vary depending upon how many flutes are included per foot, and how thick the fluting is.
