Particle bonding with rigid substrate

Hi
I wan to simulate a system very close to as shown in attached figure.
A discrete plastic web is bonded to a non-deformable but movable substrate. As the web his the wall, web should de-laminate from the substrate depending on the bond strengths.
How can the above problem modeled in LIGGGHTS?
How can we create breakable bonds between particle and non-deformable substrate?

Requesting for help, I am struggling a lot, as I am new to the environment

Thanks
