RTD-R2 Gradation Heat-Sealing Instrument Gradation heat sealing instrument can determine five groups of seal parameters at one time including heat seal temperature, speed and pressure of plastic films, laminated films for flexible package, coating paper, and so on.

Different melting point, heat stability, fluidness, and thickness of heat seal materials bring various heat seal properties and different seal technique parameters as well.

With this instrument users can get the best heat seal parameters accurately and efficiently.
