Heat Seal Tester

We are offering heat seal tester.
Hot tack measures the strength of heat seals formed between thermoplastic surfaces of flexible webs, immediately after the seal has been made and before it cools to room temperature. This heat seal property is important since this situation occurs on vertical form-fill-seal packaging.
htt-l1 hot tack tester for plastic pouches is applicable in hot tack and heat seal performance tests 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.
features of htt-l1 hot tack tester:
1. Digital p.i.d. Temperature control system
2. 4 force testing ranges and 6 testing speeds
3. 4 testing functions including hot tack, heat seal, peeling and tensile resistance are available in this instrument
4. Automatic zeroing, error alert, overload protection and stoke protection guarantee the safety operation
