A placental tissue assembly for treating wounds or surfaces of a patient has one or more layers of placental tissue and a backing material. The one or more layers of placental tissue have a first side and a second side. The backing material is adhered to and covers one of either the first or second sides of the one or more layers of placental tissue to create the assembly. The assembly when applied onto a surface to be treated on the side of the tissue opposite the backing material adheres to the surface with an attachment force greater than an attachment force of the backing material adhered to the first or second side. This allows the backing material to be released leaving the placental tissue affixed to the surface to be treated.
