sanitary napkin raw material list

1. Non-woven fabric for sanitary napkins

Non-woven fabrics are materials made out of polypropylene. They are made from long and staple fibers that employ chemical or mechanical bonds.

There are different types of non-woven fabrics according to their nature of use, but for sanitary napkins, spun-bond non-woven absorbent fabrics are used.

Non-woven fabrics for sanitary napkins are very cost-effective than woven fabrics. Woven fabrics are made by knitting the cotton together, which involves the yarn process, but non-woven fabrics, 

which are 100% polypropylene, are made by eliminating the yarn knitting process. This way, they are not only cost-effective but are quick to make.

Spun-bond Non-woven fabric for sanitary napkins is very soft and provides a gentle feel to the wearer. Furthermore, the fact that it is made from PP makes it anti-bacterial. 

Spun-bond sanitary napkins are also water-resistant, which is the primary requirement to isolate and absorb the menstrual fluid. 

The top layer of spun-bond sanitary pads is hydrophilic, which tends to absorb fluids. In contrast, the back layer of sanitary napkins is hydrophilic to avoid leakage of menstrual fluids.

Sanitary napkins are non-biodegradable. It takes 500 to 800 years to degrade the material polypropylene. 

This is a considerable threat to the global environment. But the good news is that it can be recycled to some extent to prolong its uses.

The non-woven fabric for sanitary napkins is breathable enough to deliver a gentle feeling to the women. 

The fibers for non-woven fabrics are robust and long; this makes the sanitary napkins absorb menstrual fluid with ease at a longer duration.

The breathable films have a significant market; it was estimated that its market would reach around USD 2.6 billion in 2002, and it is forecasted to reach USD 3.9 billion in2025 at a CAGR rate of 8.2%.

Breathable pe films are formed by extrusion technology. They are made from polyethylene material. 


Breathable poly-ethene films are medical barriers for hygiene products; they are widely used on the bottom line of sanitary napkins, baby diapers, and adult diapers.


Breathable polyethylene films are permeable and non-permeable. They are permeable for gases and water vapors but do not let out or in blood, water, or other liquid.


This property is significant for sanitary napkins. Breathable pe films are placed on the bottom of sanitary pads. 


They prevent menstrual blood and fluids from escaping the napkins and at the same time help the escaping of different gases and water vapors.


Furthermore, as their name indicates, these films are breathable, which means they deliver sufficient breathability to the skin to prevent the growth of bacteria. They are soft and gentle and prevent the skin from developing rashes.

3. Silicon release paper for sanitary napkins

5. SAP for sanitary napkins

SAP is known as a superabsorbent polymer. It is known to absorb many liquids relative to its mass. That’s why it’s a must component in sanitary napkins and diapers.


The superabsorbent polymer for sanitary napkins is made from sodium polyacrylate, a water-blocking material. 


SAP is available primarily in granular forms like sugar or salt granules. These multiple millions of sodium polyacrylate granules combine to form a three-dimensional structure in a crosslinking method.


When in the dry state, the polymer chains are coiled together, and when they come in contact with the liquid, the polymer structure deforms or uncoils to absorb the coming liquid. 


Moreover, these liquid molecules are not just stored in their flowing state, but the superabsorbent polymer traps them in the form of gels.


SAP has numerous functions; it is designed to make the sanitary napkin much thinner to improve its performance. Furthermore, Superabsorban polymer in the sanitary napkins helps the shin to remain dry. 


The brilliant absorption capacity of SAP enables it to absorb menstrual fluid easily without any leakages that would lead to peculiar smells and hesitation.


Super absorbent raw materials required for making sanitary pads material for sanitary napkins also counters skin irritation. Without SAP, the menstrual fluid will not get absorbed, and it will flow from the hydrophilic to the hydrophobic layer of the non-woven fabric of the sanitary napkin. 


The hydrophilic layer of the sanitary napkin does stop fluid from passing through it. Still, the weight of the liquid can easily find gaps leading to leakages, which will allow the bacteria to host and cause multiple skin problems. And it will be pretty uncomfortable for the wearer to walk in this situation.


Using SAP in sanitary napkins significantly improves the quality and dignity of the wearer’s hygiene health.
