A stampable thermoplastic composite having at least one thermoplastic layer and at least one shielding layer. The shielding layer comprises a material having an elongation to break of at least 8 percent, and the composite having an EMI/RFI shielding effectiveness of at least 30 db.

Stampable polymeric composite containing an EMI/RFI shielding layer

A magnetic theft detection system marker is adapted to generate magnetic fields at frequencies that (1) are harmonically related to an incident magnetic field applied within an interrogation zone and (2) have selected tones that provide the marker with signal identity. The marker is an elongated, ductile strip of amorphous ferromagnetic material having a composition defined by the formula M.sub.a N.sub.b O.sub.c X.sub.d Y.sub.e Z.sub.f, where M is at least one of iron and cobalt, N is nickel, O is at least one of chromium and molybdenum, X is at least one of boron and phosphorous, Y is silicon, Z is carbon, 'a'-'f' are in atom percent, 'a' ranges from about 35-85, 'b' ranges from about 0-45, 'c' ranges from about 0-7, 'd' ranges from about 5-22, 'e' ranges from about 0-15 and 'f' ranges from about 0-2, and the sum of d+e+f ranges from about 15-25.

Amorphous antipilferage marker

An improved polymer sheet. The improvement is at least one surface polymer film layer and at least one fabric veil. A veil is laminated between each surface polymer film layer and the polymer sheet. There is a method of heating a polymer sheet containing the improvement of the present invention.

Thermoplastic laminate having masked surface fabric veil layer

A magnetic theft detection system marker is adapted to generate magnetic fields at frequencies that (1) are harmonically related to an incident magnetic field applied within an interrogation zone and (2) have selected tones that provide the marker with signal identity. The marker is an elongated, ductile strip of amorphous ferromagnetic material that retains its signal identity after being flexed or bent.
