Abstract:
1. A method for reducing strain-induced curl in a multi-layer web, the method comprising: providing a coated web, the coated web including a coating applied to a web of indeterminate length, the coating being characterized by at least partially shrinking when cured; curing the coating to form a multi-layer web, the multi-layer web including a strain induced by curing the coating during a coating stress development period; and stretching the web during the coating stress development period, wherein stretching the web substantially cancels the strain induced by curing such that the resulting multi-layer web is substantially flat, wherein stretching the web increases a dimension of the web during the stretching step; wherein curing at least includes applying radiation to the coating subsequent to stretching the web in a cross-machine direction.
