Are all Chipboard Acid Free?

[goosedwn]

I bought a pack of chipboard that are made by Paperage. The pack did not say acid free. Can I assume all chipboard are acid free since there are many chipboard from Michaels also did not say acid free. The 12 x 12 paper pack that made by Paperage did indicate that they are acid free.
Thanks for your advices .

It's my understanding that no chip board is acid free.
