What is collective nouns bale used for?

It seems you're asking about collective nouns, but the word bale isn't a collective noun. A collective noun is a word that refers to a group of things or people. Examples include:

* flock of birds

* herd of cattle

* pack of wolves

The word bale refers to a large, rectangular bundle of something, usually hay, straw, or cotton. While a bale is often made up of many individual items, it's not considered a collective noun because it's not a group of living things.
