I've used contractor paper before and find it difficult to handle, not only does it add weight but it's too stiff. I buy unprinted newspaper from a box & shipping supply store. They sell it in a bundle already precut into sheets so it saves time too. I supplement that with Xmas wrap which I buy on clearance when it goes 70-90% off. I have never had an issue with Justin Beiber on my Xmas wrap packing paper If I get desperate, I will take large paper grocery or shopping bags and pull off the handle/cut off the bottom so that it's flat.
