    摘要: A self-adhesive product having a laser slit release liner and method provide improved performance and lower materials cost in self-adhesive products such as roofing and underlayment products, through-wall flashing, below-grade waterproofing and other rolled or flat roofing or other such self-adhesive weatherproofing products. A single piece release liner is applied to a roll or liner of material over a self-adhesive layer of the material. The release liner is cut into two or more segments using a laser beam. The laser beam oxidizes the adhesive region of the self-adhesive material in the area under the laser beam used to slit the release liner, thereby eliminating or minimizing unwanted adhesion caused by the migration of adhesive material when the product is rolled, stacked or stored. The laser beam may be used to create two or more segments in the release liner in a linear or curvilinear fashion.
