Market trends are moving toward thinner disposable hygiene products that also have better performance. The question is, how can we do more with less? The answer lies with adhesives.
In thinner cores, adhesives take on a bigger role and add more value. We like to call them smart adhesives, and they:
- Help prevent core shifting
- Hold the acquisition distribution layer (ADL) in place
- Stabilize the fluff/SAP (or SAP only) core matrix
- Seal the core wrap (if one is used)
- Bond materials to prevent shifting
Not all adhesives are created equal. It’s important to know your options. Among the things to consider include:
A nonwoven wrap offers faster absorption but does not reduce the risk of core crack leakage.
A tissue wrap has slower absorption, but active users stay drier.
Top core adhesive can slow down liquid absorption in to the core.
Bottom core adhesive can improve durability and speed up absorption.
When using the spray method, there is no difference between 2 gsm and 4 gsm of adhesive add-on that is applied.
Increasing adhesive add-on from 2 gsm to 4 gsm when using the multi-slot method strengthens core integrity and enhances performance.
While every material in a disposable hygiene product plays an important role, knowing how and where to use adhesive can truly impact overall core integrity and performance.
