A sanitary pad can look well made while its opening sequence still frustrates the user. The first practical question is simple: can the protective layers be removed cleanly, in the intended order?
The sanitary pad release liner protects the positioning adhesive before use. Its relationship with the adhesive, wrapper and folded product deserves a separate review during OEM development. Approving the pad's length and absorbent construction does not automatically approve the opening experience.
EDANA's menstrual-pad component guidance distinguishes the adhesive system, protective release paper and outer packaging. These components have different roles, even when a particular design combines parts of the opening sequence.
Start with the actual opening route
Ask the supplier to demonstrate the intended sequence using a finished, individually wrapped sample. Identify which part opens first, how the pad unfolds and when the adhesive becomes exposed. For a winged design, include the wing protection rather than stopping after the main liner is removed.
Different constructions may use different arrangements. Describe the sample in front of you instead of assuming that every pad should follow the same sequence. A feature that works in one wrapper design may need a different instruction or material combination in another.
| Action | Observe | Keep distinct |
|---|---|---|
| Open the individual wrapper | Opening access, unintended tearing and product exposure | Wrapper behavior versus release-liner behavior |
| Unfold the pad | Whether folded areas separate as intended | A normal fold versus damage during opening |
| Remove the main liner | Removal path, liner tearing and visible residue | Liner removal versus attachment to fabric |
| Expose the wings | Access, handling order and accidental adhesive contact | Wing handling versus whole-pad positioning |
This is a proposed review record, not an industry pass standard. Agree the actual method and acceptance criteria for the selected design. Photographs should identify the sample and the stage of opening so that a supplier can understand where an issue occurred.
Easy release and reliable attachment are different jobs
Before placement
The protective liner should be removable through the intended action without unacceptable damage or unintended adhesive exposure.
After placement
The positioning system needs its own evaluation on the agreed fabric and under the conditions relevant to the product brief.
Do not use a liner-peeling demonstration as proof that the pad will remain correctly positioned during use. Conversely, a strong attachment result does not establish that the liner is convenient to remove. Record the two questions separately.
When a laboratory measures removal behavior, ask it to specify the preparation, direction, rate and conditioning relevant to the method. Values from different setups should not be treated as directly comparable simply because both reports use the word “peel.”
Describe the defect before assigning the cause
If paper remains on the product, record where it remains and which layer appears to have separated. If adhesive is visible on a removed component, preserve that component and the matching pad. If the wrapper tears, identify whether the tear follows the intended opening feature.
These observations help define an investigation; they do not establish a cause by themselves. Avoid immediately requesting “stronger glue” or “thicker paper” before the supplier has examined the complete combination. A change intended to solve one handling problem may affect another part of the sequence.
Compare identifiable samples under consistent handling conditions. Keep unopened examples from the same sample group for follow-up. A damaged sample can document what happened, while an untouched sample allows the next reviewer to observe the opening from the beginning.
Write an actionable comment: “The wing liner tore during the intended removal action on this sample; the remaining section is shown in the photograph.” That gives the development team more to work with than “the packaging feels cheap.”
Approve the complete consumer pack
The final review should use the intended pad, wrapper and retail presentation. Record the construction revision and any relevant evaluation conditions. If later production changes a liner, adhesive or wrapper, determine which parts of the opening review need to be repeated.
Check that the instructions match the approved sequence. A technically workable design can still confuse the user if illustrations suggest the wrong starting point. Review translated instructions against the actual sample, not only against the source-language artwork.
Is release paper the same as the individual wrapper?
Not necessarily. They serve different functions, although some constructions connect elements of the wrapper and adhesive-protection system. Confirm the selected design.
Does a thicker liner automatically perform better?
No. Evaluate the complete liner-and-adhesive combination and the intended opening action. Thickness alone is not an approval criterion.
