Coles Cup Cake Liners 100 Pack

First time using these cupcake liners from Coles. The red dye from the liners seeped out onto the pan during the baking process, subsequently staining my baking tray orange. It appears to be just the red dye that has an issue, as that's the only section of the liner that's turned white. It's unclear if higher temps could cause the same issues with the other colours. I've been baking my whole life and never had this issue before. The muffins were only baked on the middle rack at 180°C; I'd expect a baking item designed to go into an oven to be able to withstand up to 220ºC with no issues.

My understanding is the dye is likely food-safe, but I wouldn't recommend buying these.
