When choosing your board grade, keep in mind that the cardboard shouldn’t be your only form of protection. We can always make inserts, sleeves, pads, etc. Out of extra cardboard so that your product is shipped in fully sustainable packaging. But if your items are fragile, check out our packaging supplies range for added protection through shipping.
3CS (4mm thick) AKA: 430KC or C85
3CS Board is approx. 450GSM in weight. We’ve chosen this corrugated cardboard as our “go to” grade. It is a lightweight grade of board, which is sturdier and stronger than the standard 3C grade other suppliers use. Best for self supporting items, plastic items, light metal objects with smooth edges, and general packaging. Best styles are RSC, CCF and 5PF.
1CS (4mm thick) AKA: C35 or 600KC
Jet’s Favourite board grade!
1CS is approx. 650GSM and strong enough to be mistaken with Twin Cushion cardboard. Uses: Almost any item that’s self supporting, but needs high strength or stackabilty. Food items; Chicken, meats, dried foods, freezer transported goods and even great for goods in refrigerated transport.
3BC (7mm thick) AKA: 790KBC or BC49
Our lightest TWIN CUSHION option. – Better than almost any import boards.
Twin cushion is 2 layers of fluted board (like a wave) sandwiched between 3 flat layers. Some call it 5 ply. The added cushioning makes it great for Pallet Sized Boxes and larger sizes. It’s also great for fragile items.
(upgrade to 1BC if required, just email or call us)
1EB (5mm thick) AKA: 825KBE or BE59
Don’t be fooled by the 5mm thickness. This board is made of 2 special flutes; E-flute and B-flute. It is so dense and strong, that some clients call it “brick board”. Our top offering in the custom box calculator – and for good reason. Don’t want your products sent back due to breakage? Pick this board grade…
