1000 Micron SRA4 Greyboard Backing Board

When You Need a Bit More Backbone.

This 1000 micron (1mm) SRA4 greyboard gives you that extra thickness and extra size—because sometimes standard A4 just isn’t enough. Measuring 225mm x 320mm and made from 100% recycled fibre, this board is great for packaging inserts, rigid backing, folders, or anything that needs a little extra heft.

Uncoated for versatility and cut clean to SRA4 size, it’s happy to be glued, stacked, taped or trimmed to fit. Plus, the price includes VAT and UK delivery, so there’s no mental maths needed at checkout.

Frequently Asked Questions

What’s the benefit of SRA4 over A4?

SRA4 gives you a bit of extra room—handy for bleed, trimming, or when A4 is just that tiny bit too small.

Is 1000 micron suitable for packaging?

Yes – it’s strong enough to protect and flexible enough to shape or cut easily.

Can I cut or shape it by hand?

Definitely. A sharp knife or a guillotine will work wonders.

Can I test it before buying in bulk?

Of course. Order a small pack to make sure it fits the job before going big.

Do you offer custom sizes?

Yes! Just get in touch with your measurements and we’ll do our best to sort it for you.
