I Placed A Spill Catching Liner In My Oven And

I placed a spill catching liner in my oven and by accident, because of in a hurry, placed it on the burner. I was cooking pizzas and noticed a burnt smell opened it and noticed the burner was burning the plastic catching liner. I pulled it out immediately let some smoke out but continued to bake the pizzas. Was it ok to eat the pizzas? It was probably in there for 2 mins with the pizza out of a total of 15 mins cooking.
