Uniaxial elastic laminate film |
摘要 |
<p>Monoaxially elastic laminate film (A) has (i) a core layer (CL) of thermoplastic elastomer and (ii) at least one skin layer (SL), co-extruded with CL. <??>Monoaxially elastic laminate film (A) has (i) a core layer (CL) of thermoplastic elastomer and (ii) at least one skin layer (SL), co-extruded with CL. SL is made of a thermoplastic polymer that has a brittle molecular attachment, and, under application of an extension force, extends only slightly and when a predetermined tear force is applied, it tears without a transition. The attachment is broken irreversible by a uniaxial stretch in the extension direction, but transversely to this direction it remains intact, so the film is stiffened in the transverse direction. <??>An Independent claim is also included for a method for preparing (A).</p> |
