Can anyone explain what the author means by "bond" in this context? Is it a specific mathematical term, or did they mean to write "bound"?

[goodside]

The author is confusing bond with bound. The introduction contains this sentence: "Second, all pages are bond from the top and cannot be torn off."

Bond is fine writing paper.

Ah, silly me, I should have read the article and not just the comments. Bond does indeed describe the paper but as someone else pointed out it isn't what the article is talking about.
