Hygiene products benefit from adhesives for non woven materials
Hygiene products market is the biggest, and fastest growing, user of non-woven materials. The materials are used in products like baby diapers, adult incontinence products, children’s swim and training pants as well as feminine hygiene pads and shields. All these products also require adhesives for non woven materials to bond the different layers together.
Diapers, feminine hygiene products and incontinence products are all mass produced low cost products. The high production and reduced costs are made possible by using adhesives. Even though only a small amount of adhesive is used per product (4%, 1 to 1.5 g in an average baby diaper), the adhesives really make a difference. They not only bond components together but also guarantee fit, retention, breathability, absorption and comfortable feel.
Adhesives for hygiene product reliability
The adhesives for non woven materials in hygiene products must be fast and easy to apply as well as fast curing due to the required efficiency of the production. For example an average diaper manufacturer makes between 800 and 1000 baby diapers per minute. Next to fast production, the adhesives for non woven materials must contribute to the product quality and reliability.
The choice of adhesive for non woven materials in hygiene products is primarily based on two factors: the required bond strength between layers and effectiveness of elastic bonding. The latter is measured by elastic creep tests and the former by peel strength tests. The poor choice of adhesive can lead to for instance leakages and skin irritation.
Hot melt adhesives make up the most reliable and comfortable hygiene products
Currently the best adhesive for non woven materials in diapers, incontinence products and feminine hygiene pads and shields are thermoplastic hot melt systems. These are plastic like 100% solid adhesives which take a liquid form when heated, hence the name hot melt. Hot melt adhesives for non woven materials allow for high production efficiency, low costs and extreme product reliability.
Advantages of using adhesives for non-woven materials in diapers and other products
The carefully chosen adhesives have a great impact on the quality and reliability of the finished products. They make sure the non woven material remains elastic, seams are flexible and absorption properties are not disturbed. Additionally, ever-improving adhesives allow for thinner products with increased comfort. All in all, thanks to adhesives diapers, pads and incontinence products:
- Stay in place
- Are easy to remove
- Allow for movement
- Are discreet and do not show
- Feel soft and are comfortable to wear
- Result in less waste
Meeting the needs of more sustainable consumers
Regardless all the advantages and quality factors, the hygiene products that use non woven materials are disposable and therefore, not always considered the most sustainable. Fortunately, the recent developments in the area of hot melt adhesives, diapers, pads and other disposable hygiene products are becoming more and more sustainable. One of the greatest innovations is biodegradability of hot melt adhesives. These are already used in the packaging industry, and about to make an entry in the sector of hygiene products.
