I tip for takeout depending on the service and what is entailed in packaging up the food. I think a good takeout tip is 10%. I get sushi from a place a few blocks from my house and it is always packaged very carefully, they know my order when I call, and they occasionally throw in a new item they think I might like for free. I feel like they earn a 10% tip.

Same with Chinese food. If it is carefully packaged they have earned some form of tip. They could have put it on a plate and brought it to the table or carefully packaged it and brought it to the front of the restaurant. The effort involved is slightly different and the tip should reflect that, but shouldn't be eliminated entirely.

On the rare occasion I order pizza the delivery guy gets a tip.

It's simple. A tip is based on service. If one was performed, a tip is warranted. How much is an entirely personal and subjective decision.
