	*PARAM　　HST-H3 Heat Seal Tester: PARAM Heat Seal Tester seals the specimen to determine the seal parameters of basic film, laminated films, coating paper and other heat sealing laminated films according to the requirement of relative standards. The seal parameters include heat seal temperature, dwell time, and the pressure of heat seal. Heat seal materials that have different melting point, heat stability, fluidness, and thickness of could show various heat seal properties, which cause obviously different seal technique. Users can obtain standard heat seal index by HST-H3 Heat Seal Tester.
	*PARAM　　HST-H5 Heat Seal Tester: HST-H5 is applicable in heat seal test of flexible packaging materials under various preset temperature, pressure and time, by which can customers get best parameters to fit the requirements of actual manufacture.
	*PARAM　　RTD-R2 Gradation Heat-Sealing Instrument: PARAM RTD-R2 Gradation heat sealing instrument can determine five groups of seal parameters at one time including heat seal temperature, time 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.
	*PARAM　　HTT- L1 Hot Tack Tester: PARAM Hot tack tester is applicable in hot tack property test for plastic film, laminated film and other packaging film. Meanwhile, it is applicable in peel, shear, tension and other test items for adhesive, adhesive tape, laminated film, plastic film, paper and other flexible materials.
