Even in traditional disposable hygiene cores, not all diaper manufacturers use a core wrap. When they do, the core wrap’s main job is to keep the fluff and superabsorbent polymer (SAP) matrix contained at the centre of the core. It is also important to note that adhesives can be used in several ways. They include sealing the core, bonding adjacent materials, and preventing core shifting. Keeping the core in place creates a more comfortable fit for the wearer and allows for best performance during use.
There are two types of core wraps manufacturers typically use today:
- Nonwoven wraps have faster absorption but do not reduce the risk of core crack leakage.
- Tissue wraps have slower absorption but are known for helping active users stay drier. They reduce rewet and hold up better against core cracking.
Whenever you look to modify the core, adhesive selection is critical for comfort and performance. Don’t forget to seek advice from our disposable hygiene adhesive experts at Bostik early in the process.
