This is a cohesive interaction.

The interaction between wax paper and water is adhesive. Adhesive forces are when two different substances stick together, whereas cohesive forces are when the same substance sticks together. In this case, the water molecules are attracted to the wax paper, causing them to adhere to each other.
Capillary action is the process where water is absorbed and travels through a paper towel due to the interaction of the liquid with the towel's fibers. This phenomenon is driven by the combination of adhesive and cohesive forces.
Adhesive is the ability of a substance to stick to other surfaces, like glue sticking to paper. Cohesive is the ability of a substance to stick to itself, like water droplets sticking to each other. Remember "A" for adhesive (sticks to other surfaces) and "C" for cohesive (sticks to itself).
Water moving up into a paper towel is attributable to capillary action, which is the ability of a liquid to flow in narrow spaces without the assistance of, or even in opposition to, external forces like gravity. This phenomenon occurs due to the adhesive and cohesive forces between water and the paper towel fibers.
Self-adhesive paper with a protective waxed backing is typically known as "self-adhesive sticker paper" or "label paper." The brown waxed paper strip protects the adhesive coating until it is ready to be applied.
Water is absorbed into paper towels due to capillary action, which is the ability of a liquid to flow in narrow spaces without the assistance of, or even in opposition to, external forces like gravity. The porous structure of paper towels allows water to be drawn into the tiny spaces between the fibers, where it is held by adhesive and cohesive forces.
