Frequently Asked Questions

What is SRA4?

SRA4 is slightly larger than standard A4—great when you need a trim margin or print bleed space. It measures 225mm x 320mm.

Is 750 micron strong enough for packaging?

Yes – it’s sturdy enough for lightweight packaging, envelopes, or as a stiffener for prints and inserts.

Can I cut it easily?

Yes – a craft knife and ruler will do the trick. It’s thick enough to hold its shape, but thin enough to cut cleanly.

Can I test it first?

Definitely. Order a small quantity before committing to a full pack. Try before you buy!

Do you offer custom cuts?

We do. Contact us with your measurements and we’ll let you know what’s possible.
