No. What you have there is called steak paper or deli paper. The coating prevents leakage. Here is a piece of steak paper on top of butcher paper, butcher paper is dull on both sides.
And here is a butcher paper pouch... you can see the paper does soak up some oils, but once it is saturated the leakage in minimal.
