Does any one know if Orijen is vaccum packed?

ive just started feeding this alongside raw food,the bags seem to have the air sucked out,but not sure if this is vacuum packed,I cant find anything obvious on the bag.Sorry,imnot much help!

I used to order 4 bags at a time and there is no consistency.  Some of them seemed to be vacuum packed and others weren't although there didn't appear to be any tears in the bags as there was air in them.

No it's not.
I think the difference in packs is something to with where in the packaging line the bag comes from. Some get squished up, some not so much.
