**Same GSM ≠ Same Cup Performance.**
A buyer may ask for:
“230gsm cupstock.”
But for a paper cup manufacturer, that is only the beginning.
The real performance of **cupstock paper** also depends on:
✅ Bulk & stiffness
✅ Base paper quality
✅ PE coating weight
✅ Single PE or double PE
✅ MD / CD direction
✅ Corona treatment
✅ Reel width, core, OD & winding
✅ Final application
Because even two papers with the same GSM can perform differently during **printing, forming and sealing**.
A hot cup, cold cup, paper bowl and ice-cream cup may all need different material structures.
So instead of asking only:
**“What GSM do you need?”**
A better question is:
**“What are you producing, and what does your production line require?”**
That is how we select the right ** PE-coated cupstock paper** for better forming, better consistency and more stable production.
**DON’T JUST BUY GSM.
CHOOSE THE PAPER THAT FITS YOUR PROCESS.**
Need help checking a cupstock specification?
Share your **application + GSM + PE coating + reel size**, and we can review the structure together.
