Microtextured films with improved tactile impression and/or reduced noise perception

A film layer having a micro-textured surface is provided. The film layer has a continuous phase with one or more thermoplastic polymers, wherein at least one of the thermoplastic polymers is a low-modulus polymer having a 2% secant modulus of less than or equal to 140 MPa, and the film has from 10 w...

Beschreibung
Zusammenfassung:	A film layer having a micro-textured surface is provided. The film layer has a continuous phase with one or more thermoplastic polymers, wherein at least one of the thermoplastic polymers is a low-modulus polymer having a 2% secant modulus of less than or equal to 140 MPa, and the film has from 10 wt% to 100 wt% of the low modulus thermoplastic polymer. The film layer also has a discrete phase with from 5 wt% to 45 wt% of a thermoplastic starch. 本发明提供具有微纹理化表面的膜层。所述膜层具有含种或多种热塑性聚合物的连续相，其中所述热塑性聚合物中的至少种为具有小于或等于140MPa的2％割线模量的低模量聚合物，并且所述膜具有10重量％至100重量％的低模量热塑性聚合物。所述膜层还具有含5重量％至45重量％的热塑性淀粉的离散相。
