Frequently Asked Questions

What is SRA3 size?

SRA3 is slightly larger than standard A3—320mm x 450mm. Great for printers who need a trim margin or bleed area.

Is 750 micron strong enough for backing?

Yes – it’s ideal for lightweight packaging, inserts, dividers and general print support where a bit of stiffness helps.

Can I cut this by hand?

Absolutely. A sharp blade and straight edge will give you a clean finish. It’s also guillotine-friendly.

Can I try it before ordering a bulk pack?

Of course. Small pack options are available so you can test it first.

Can I get it in a different size?

Yes – send us your specs and we’ll let you know what we can do.
