Abstract
The present invention includes a thermoplastic receptor for radio signals having a frequency of about 1 to 100 MHz, the receptor having a dissipation factor of about 0.1 or greater. Also disclosed are heat meltable adhesives, film compositions, and composites comprising a thermoplastic and a thermoplastic receptor. The present invention also includes a method of applying a thermoplastic composition by applying radio signals having a frequency of about 1 to 100 MHz to a composition comprising a thermoplastic composition and a receptor.
