How To Choose A Board Grade

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…

There are approximately 80 different board grades in our inventory. The grades chosen in the custom box calculator are our most commonly used grades. Colour may vary, depending on which supplier we purchase from at that time. For anything else; white boxes, B-flute, E-flute, etc. Please send through an enquiry. 

Jetbox board grade guidelines are recommendations only. We will always do our absolute best to provide the highest level of service and quality at all times. Breakages and returns happen, and we’re here to help you keep it to the bare minimum!

Over & Under Runs

Manufacturing processes require machinery to work at quite high speeds. During production, some sheets may be damaged and need to be replaced. In some instances, we cannot replace the sheets at that time and you will be met with a slightly lower Quantity than ordered. This amount will be credited to you.

In most cases though, there will be overruns, as the machinery cannot come to a complete stop in an instant – we require a gradual slow down, which will give us more cartons produced, than what are ordered. These overruns are payable by the client. And taking them also helps save on recycling, which is more sustainable and better for the Environment in the long term.

If you require EXACT Quantities, we may have to make some boxes in a different grade than ordered, to make up your order in the Exact Qty required. These requests will also Incur higher unit costs. This cannot be avoided, as we must consider the recycling processes and costs involved, in helping to reduce our carbon footprint.

We're still here for you!

We’re still open for ONLINE ORDERS – delivered straight to your door! If you need to collect your order from our warehouse, we will contact you to arrange a time.
