I have made several food packaging boxes before, but I found someone to design them and then printed them myself. I didn't find a big company, and the quotations from big companies were too scary. Later, I found the design of Chengdu Panda on the Internet, and the design was OK, and the charge was cheaper among the several I asked. The quality is not bad. Their company can make it in package, but in order to save costs, and since I am not from Chengdu, I will find someone else to make it, but the price is similar. If you are from Chengdu, you can try it. It's on the tower of Noah's Square in jinniu district.

Personally, I think this company is relatively reliable, and I'm too lazy to haggle over the rest.
