Thermofoil heaters are thin, flexible heating elements consisting of an etched foil resistive element laminated between layers of flexible insulation. Since their introduction by Minco over 45 years ago, Flexible Thermofoil heaters have demonstrated significant advantages over conventional electric heaters.
Precise Heating :
Thermofoil heaters put heat where you need it. You simply apply them to the surface of the part to be heated. Their thin and Flexible profile gives close thermal coupling between the heater and heat sink. You can even specify profiled heat patterns with higher watt densities in areas where heat loss is greater.

Alper S.R.L is a leading Company in the development and production of flexible electrical resistors called PTF (Polymer Thick Film).
Thanks to the use of special conductive inks or pastes printed on polyester sheet, ALPER is in a position to produce resistors in many shapes and very reduced thicknesses (generally 0.2 mm) to suit the specifications of the end product.
The inks, that have been developed by our Company, in some particular conditions may show PTC features (Positive Temperature Coefficient); this means that they are able to limit the heat produced, with no need to apply a thermostat and with no risk of overheating.
This type of resistor offers many advantages when compared with the more traditional electrical resistors now on the market.
The particular features of PTF heaters make them so versatile that they can be employed in a wide range of applications in both the domestic and industrial sector.
