tbh, if it needs heat to press, that's a sign of lower quality if anything. High grade trichomes will press at room temperature or with the heat of your hands.
Selling tactic for making low grade hash sound better then it is. Could just be kief that has been heat pressed through a pollen press. I'd imagine that's what this is.
I think the 6x means it's supposedly sieved 6 times.
All the hash I've done in the US was very strong, even if made from Mexican commercial. However in Europe it's common to cut hash(heresy!), often to the point where it's as weak as low-grade weed. It's called soapbar hash.
