The BRAVO HTT Series of heat seal testing equipment is specially designed to simulate heat sealing condition and affecting parameters for determination of heat sealing ability of plastic films, composite films, coated paper, and other sealing films under specified sealing conditions.
The heat sealing ability of materials is a function of temperature, pressure and duration of temperature and pressure applied for creating a seal and greatly affected by the factors of melting point, thermal stability, fluidity and thickness. The optimal heat sealability parameters can be obtained accurately and efficiently.
