Air-Laid Paper and SAP Sanitary Napkins OEM: Core Material Selection Guide

Air-laid paper and SAP are important materials in many sanitary napkin core designs. Buyers should understand how they work together before comparing samples or requesting a private label quote.

For OEM and private label buyers, product specification is the language that connects brand positioning, sample approval, factory production and shipment inspection. A clear specification reduces misunderstandings and makes repeat orders easier to control.

Role of SAP in the core

SAP helps lock liquid inside the absorbent core and reduce rewet when used correctly. The right amount depends on length, thickness and target absorbency.

• Liquid locking and dryness support.
• Better performance for night or heavy-flow SKUs.
• Requires good distribution to avoid hard spots.
• Should match topsheet and acquisition layer speed.

Role of air-laid paper

Air-laid paper supports structure, softness and liquid distribution. It can improve core feel when combined with suitable pulp, tissue and SAP design.

How buyers compare material choices

Ask for the full specification and test data, not only material names. Compare absorption speed, total capacity, rewet, thickness and cost by SKU.
