Absorbency Sample Test Record for Sanitary Pads and Menstrual Pants Buyers

Absorbency is an important sourcing topic for sanitary pads and disposable menstrual pants, but a single headline value rarely gives buyers enough information for approval. A stronger OEM review records the exact sample, test method, liquid input, timing, surface observation and core condition. The purpose is to compare sample directions consistently, not to turn a small internal check into a universal performance promise.

Identify the Exact Sample

Start with a sample code, production or receipt date, product type, size or length, material version and packaging version. Photograph the unopened item and the unfolded product. If two samples look similar but use different topsheets, SAP ratios, fluff pulp structures or backsheets, give them separate codes.

Define the Review Method

Record the liquid type used for the internal comparison, the amount added in each step, the interval between additions and the position where liquid is applied. Also record room conditions when they may affect the observation. Buyers should ask the supplier to explain whether a result comes from a development test, a finished-product inspection method or an informal demonstration.

Observe Intake and Distribution

Note how the liquid enters and spreads through the absorbent area. Review whether distribution remains concentrated or moves along the core, and whether the sample shape changes. These observations help buyers compare constructions, but they should be connected to the intended use scenario and repeated across several samples.

Check the Surface After a Defined Interval

Use the same waiting time and contact method for each comparison. Record the surface condition in neutral language such as visibly damp, slightly damp or comparatively dry under the selected method. Keep wording tied to observed test conditions and avoid absolute performance promises. A laboratory or buyer-approved protocol is needed when a formal numeric specification is required.

Review Core Stability

After the test, inspect bunching, cracking, uneven swelling and movement of absorbent material. For menstrual pants, also review how the core sits relative to the waistband, leg openings and front-to-back coverage. For sanitary pads, check the relationship between the core, wings and release-paper area.

Include Pressure and Handling Observations

If the review includes pressure, define the weight, contact area and duration. Record any visible return moisture or edge movement without converting the result into an absolute consumer claim. Handle all compared samples in the same way so the record remains useful for revision decisions.

Compare Multiple Samples

One item cannot represent an entire production order. Review several units and note variation. If a material or process adjustment is requested, issue a new sample code and repeat the relevant checks. Keep the approved reference sample, photos and written observations together.

Turn the Result Into an RFQ Specification

The RFQ can state the product type, length or size, intended channel, core direction, preferred thickness, packaging quantity and requested sample-review method. Separate required specifications from options still under discussion. Final performance wording should follow the accepted sample and documented test basis.

Buyer FAQ

Is one absorbency demonstration enough for approval? No. Buyers should use repeatable methods and multiple samples.

Should test wording appear on packaging? Only after the method, evidence and destination-market requirements have been reviewed.

What should be kept for repeat orders? The approved sample code, test record, photos, specification and packaging version.
