The use of melt-flowable materials for sealing surfaces or applying design elements

摘要

The invention provides a method for imparting topographical or protective features to a substrate by contacting a sheet material comprising a thermoplastic layer with a substrate and heating the sheet material to an elevated temperature. The invention also provides a sheet material which comprises at least one layer consisting essentially of one or more thermoplastic, melt-flowable polymers that are semi-crystalline at room temperature.
