Abstract
The present invention relates to a process for printing specific adhesives onto articles, such as absorbent articles or release paper, using a specific transfer tool and/or a specific adhesive, having a specific peel force, viscosity, elastic loss modulus, elastic modulus, surface energy and loss tangent modulus; the invention also relates to articles comprising the specific adhesives and to specific printing rolls.
Claims7
An absorbent article, comprising a sticky material which has a peel force of at least 0.1 N/cm at an average basis weight of 20 g/cm2 and
- a viscosity η of less than 2500 mPa·s at a temperature of between 80 degrees C. to 250 degrees C.;
- and
- an elastic loss modulus G′, which increases from 10 to 10,000 Pa in less than 60° C. temperature range as measured by the method ASTM D4440-95, using flat plates oscillating at 1 Hz, wherein the sticky material is disposed on a garment facing surface of the absorbent article.
An absorbent article comprising a sticky material which has a peel force of at least 0.1 N/cm at an average basis weight of 2 g/cm2 and a surface energy σ at 20° C. of less than 25 mJ/m2.
