Ultrathin underpads: these are, as a rule, 6-layer underpads, in the manufacture of which an additional reinforced rolling and embossing of the canvas in hot shafts is used, which makes them very dense and compact, but the absorbent properties of the underpad do not decrease. The amount of pulp in these models is usually reduced, as it begins to play a secondary role: a distributing and binding layer for powerful super absorbing polymers that take on the main work of liquid absorption.
Scheme of ultrathin products:
1. Coating layer – nonwoven material
2. Covering layer of sanitary tissue paper
3. Layer of small crystals of super absorbing polymer (SAP)
4. Distribution layer: fluff pulp (optional)
5. Supporting layer: sanitary tissue paper
6. Protective layer: PE film
Scheme of ultrathin products with baking soda or any other component:
1. Coating layer – nonwoven material

4. Distribution layer: fluff pulp (optional)
5. Layer of small crystals of baking soda or any other add
