Quality that you deserve
The demand for sanitary napkins and other menstrual products has been growing with increased awareness about menstrual health in the local as well as indian markets.
It is a great time to be become an entrepreneur in the sanitary napkin business. Our founders Rachna Kuntal, Yogendra Singh, and Bhupendra Singh Kuntal (Manager) came together on a mission to create fully eco-friendly, compostable sanitary Pads, napkins, Diapers from the state of Uttar Pradesh.
On starting business we tied up with famous & registered manufactured to take premium quality raw products. after that Gravitas hygiene helthcare marketing & packaging with own brands and distribute securly to his customers.
We were inspired by the idea of improving women’s access to sanitary pads in India. We passionate about making a product that is sustainable using natural materials and impacts women. We have previously commercialized and launched sustainable natural-dye crayons made by local artisans in Uttar Pradesh, India.
How our products made ?
There are multiple layers in a sanitary pad. If the layers are not properly sealed it can cause leakage. Leakage and staining can make the pad buyer never buy your pad again. So, let’s understand how we can eliminate sealing issues.
Types of sealing that are typically used in pads.
- Adhesive sealing
- Ultrasonic technology
- Combination of Heat sealing + boundary sealing + Adhesive hot melt sealing.
Adhesive sealing
In this type of sealing, the adhesive is used as a sealing agent to bond the overall raw material of the pad. Even in this, there are two types of adhesives (a) cold melt adhesive and (b) hot melt adhesive.
Cold melt adhesive is used mainly in small scale, manually operated machines. It is generally not recommended due to poor sealing strength. Also, since the application is done manually, the amount applied can vary from pad to pad making it inconsistent and unhygienic to use.
In Hot melt adhesive, the adhesive is heated at a certain temperature and then applied via machines and thus making sure the amount of adhesive used in the pads is consistent. Hence, pads in this type of sealing have less chances of leakage. Additionally, good quality hot melt glues sourced from reputed suppliers have a much better bonding strength than cold melt adhesives.
Ultrasonic technology
In ultrasound sealing, the sealing process uses an acoustic vibration to generate heat and causes the thermoplastic fibers to bond together sealing the pad. While eliminating glue sealing is good, but one has to be aware of the drawbacks of ultrasonic sealing:
- Ultrasonic technology only works on sealing similar types of raw materials (for eg. the bonding strength of non-woven to non-woven material will be good, but non-woven to PE film may not be strong, leading to leakages.
- Ultrasonic horns and generators have to be handled carefully, else it can have high maintenance cost and wear and tear
Requires skilled operators. - Improper setting or embossing design can lead to creation of pin holes on the pad which causes leakage.
Heat sealing + boundary sealing + adhesive hot melt sealing
In this sealing, the pad’s top sheet, back sheet, and absorbent core are bonded by adhesive hot melt sealing between all the layers. Then the pad is again sealed by heat sealing to make the sanitary napkin leakage proof and lastly, boundary sealing is done on the pads (i.e – the pad is sealed from edges) making the pad secured for side leakage as well. It is a robust way of sealing and is used in our Swachh machines to make sure the quality of the sanitary napkins is up to the approved BIS standards!
High Absorption Core
Core – A combination of SAP+ Airlaid paper or wood pulp fluff is used as an absorbent in pads to absorb and lock the blood.
While this is the most important part of a sanitary pad, it is also the most expensive. It is important to optimize design to ensure maximum absorption and minimum core wastage.
In several low cost ultrasonic sanitary pad making machines the absorbent is continuous end to end to reduce the number of processes in the machine to make the machine low cost. But this compromises on the quality of the pad because the edges of pads are not sealed equally around the entire periphery/boundary, making it susceptible to opening of pad from the front or back, and causing leakage
Barrier backsheet
To avoid leakage and protect the absorbed blood from staying inside the pad, the quality of the backsheet is important. Make sure to choose the appropriate GSM of the backsheet depending on the raw material type (PE backsheet or compostable backsheet) to have appropriate thickness to endure heat sealing and tear resistance.
Release Paper and Disposal of pads
Positioning glue is applied on the backsheet of the sanitary pad which helps the pad stick to the undergarment. In order to keep this glue intact before usage, a release paper is used. In Swachh machines, by design we have added a few delight features in the release paper. The release paper can have branding or usage messages printed on them. The release paper can also double as disposal wrapper -basically, it works as a covering paper for the pad after use.
In most of the low cost sanitary napkins that are available, the release paper is typically small and doesn’t cover the whole pad. If the release paper is small it creates an issue while throwing the pad. As the whole pad is not properly covered it becomes difficult to dispose of. Some high priced pads provide additional plastic wrapping for disposal, which creates more plastic waste and increases the cost of the pad as well. So, choose the design of even the release paper wisely.
Perfumes and colours
There have been a few news articles lately pointing out the side affects of some chemicals used in sanitary pads. Perfumes and colours are not important for sanitary pad performance and, thus, can be avoided. It will also help reduce the cost of the sanitary pad and avoid risks of allergies and rashes for people with sensitive skin. As an innovator if you plan to add any new or different ingredients in a sanitary pad, make sure to send your pads for BIS standards and toxicity testing.
