The third layer is a mix of imported super absorbent polymer from Japan and imported high quality fluff pulp from the United States, which forms the super absorbent core that can lock dog urine and prevent reverse osmosit effectively.

The fourth layer is also made of tissue.

The back layer is made of leak-proof PE film ( with/without adhesive strip ).
