The disposable hygiene core is one of the hot topics in the industry today. From baby diapers to the products created for adult incontinence and feminine hygiene, many of the issues overlap. Make it thinner. Make it more absorbent. Give it channels. Keep it from cracking, because leaks are bad for business. 

At the same time, the list of consumer expectations continues to grow. It is easy to see why manufacturers are researching and experimenting with new core designs to stay competitive. Understanding the key functions of the core system is the first step in meeting user needs and exceeding expectations.

Today, a top performing core should:

  • Attract and absorb fluid away from skin
  • Disperse fluid quickly throughout the product
  • Prevent the feeling of a wet sensation after fluid is released
  • Promote skin wellness by avoiding rewet
  • Hold up to the stresses of daily life without cracking and leaking
  • Ensure comfort by not shifting, bunching, or sagging during use
  • Offer protection against noticeable odours
  • Provide even the most self-conscious adult users with the discretion they desire

The most common cores today are the traditional blend of fluff and superabsorbent polymer (SAP), the channel core, and the compound/pre-compound core. The different materials used in these cores are essential for achieving performance goals. A quality topsheet, which makes direct contact with the skin, assists fluid acquisition after insult while helping to prevent rewet. The Acquisition Distribution Layer (ADL) enables rapid fluid movement to the core. The core then distributes, soaks up, and traps the fluid. 

Supporting the function of each of these core system components, and many others, is the adhesive. But every adhesive isn’t created equal. No adhesive works in every core design or every application within the core. Choosing the right adhesive can enable optimal performance and core integrity. As trends continue to shift towards products with a thinner core, you need the right adhesives to do more with less.

Is your company looking to enhance and advance the core system in the products you produce? It is important to know your options for core adhesives and select a partner who can help you achieve your performance goals.
