According to the Longman Dictionary of Contemporary English, it seems that this is called "a packet of crisps" (Lognman | crisp), but the same dictionary says that "packet" is British English. (Longman | packet) I would like to know what native speakers of American English would call the picture above.
[Edit] The first time I saw the picture, I thought native AE speakers would call it "a bowl of potato chips", but according to the Longman Dictionary of Contemporary English, a bowl is "round" (Longman | bowl), so I am assuming that "a bowl of potato chips" does not work.
