Of course "pack" can be a noun. I didn't say otherwise (presuming that your reference to nouns versus verbs was in reference to one of my posts on that point). However, just as you've used it, a "pack" is a collection or holder of things. Hence, it doesn't work in this context because the type in question holds a single integer type of some number of bits/octets.
