Packaging options

I’ve been looking for strong but lightweight packaging options in particular for larger prints, my largest prints are currently 60 x 80cm. Over the past few years I’ve used many different options, including bubble wrap bags, and all of the cardboard and bubble wrap that has come into our home, I strongly advise recycling packaging as often as you can if you have the storage space to do so.


Greyboard seems like an excellent solution as a substrate to strap on either side of a print, I’m going to give it a go. I am going to try 2mm, 1,260 gsm and see how that feels as a protective option, I’ll probably wrap that in something, or just tape it up the edges… I’ll come back to this to update next time I send something out, note that my prints are in cello packs to give them a waterproof protection prior to packaging.

I found this extremely useful chart from on conversion from grammage to mm.

There is a formula to calculate the thickness of the greyboard simply as below.

Thickness (mm) = Grammage (gsm) * 1.55 / 1000

For example, if the grammage is 1290gsm, then

Thickness (mm) = 1290 * 1.55 / 1000 = 2 mm

Below is a conversion table for the common greyboard thickness and grammage that are used for the cardboard gift boxes, rigid boxes and set up boxes.

615gsm 1mm

775gsm 1.2mm

970gsm 1.5mm

1160gsm 1.8mm

1290gsm 2mm

1420gsm 2.2mm

1581gsm 2.4mm

1645gsm 2.5mm

1805gsm 2.8gsm

1845gsm 3mm

2150gsm 3.5mm

2460gsm 4mm
