1. Ievads hot tack Testing Equipment
Hot Tack Testing Equipment measures the strength of heat seals formed between thermoplastic surfaces immediately after the seal has been made and before it cools to room temperature. Hot Tack Testing Equipment also has functions of karstuma zīmogs, tensile and peeling force test.
2. Tehniskās īpašības
1) Able to perform hot tack, heat seal, peeling and tensile test in one.
2) Precious and stable P.I.D. temperature controller
3) 7-inch HMI touching screen for easy operation
4) PLC controlled
5) Aluminum encapsulated sealing jaws
6) Testing speed adjustable
7) Auto zeroing, overload and over travel protection
8) RS 232 port and professional software(optional)

6. Advantages of hot tack testing:
It quantifies the impact of dump loading a bag on the hot seal integrity on a vertical form fill and seal machine.
Higher hot tack and seal strength at lower temperatures is advantageous.
Adding 30% LLDPE compound to LDPE films significantly enhances hot-tack seal strength.
