Heavy Flow Sanitary Pads OEM: Absorbency, Length and Leak-Guard Specification

Heavy flow sanitary pads must deliver confidence under higher liquid volume and longer wearing time. For OEM buyers, heavy-flow positioning should be supported by measurable absorbency, coverage and leak protection.

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.

Specification points for heavy flow

Define length, core capacity, SAP distribution, topsheet dryness, wing fixation, side-leak channels and back coverage. These details matter more than broad claims.

• Longer core and wider protection area.
• Higher absorption capacity with low rewet.
• Leak guards or channels for side protection.
• Packaging wording matched to destination rules.

How to test heavy-flow samples

Use absorption speed, total capacity, rewet and leakage simulation. Test the sample after compression to reflect storage and real-use conditions.

Retail positioning

Heavy-flow pads can be sold as overnight, extra-long or premium protection depending on market preference. Packaging should explain the use case clearly.
