Peel Testing for Construction Adhesives in Disposable Hygiene
Adhesives play many important roles in disposable hygiene products.
These range from enabling construction using a variety of substrates and elastic strands to indicating wetness.
When focusing specifically on construction adhesives—those that bond multiple substrates in place—the adhesive’s ability to resist peel is very important.
Peel adhesion is the force required to separate two substrates bonded together by adhesive.
Sufficient peel strength is required to ensure that there is a good bond between substrates in a disposable article.
In the worst cases, without sufficient peel, a hygiene product’s ends or edges can open.
This may allow the core to come out of the product, or features such as ears may come off in use.
Peel testing measures the amount of force required to separate a laminate bonded by adhesive at a specified **crosshead speed**.
This is completed using a “T” peel configuration.
In addition to determining the force required, peel testing also identifies the failure mode.
For example, peel testing can help determine if the failure is:
Adhesive (the adhesive remains on one of the substrates)
Cohesive (the adhesive separates with part remaining on each of the substrates)
