Heat-Seal Temperature Sensor
A temperature testing package offered by Sensor Products provides an accurate approach to ensure proper heat-sealing temperatures for blister packaging. A tactile temperature-indicating material known as Thermex®, together with a temperature analysis system called Topaq®, gives packaging professionals a solution for testing and analyzing heat-sealing bar temperatures used in blister-seal packaging production. Suitable for pharmaceutical clients whose products require moisture barriers. Customers warm the seal station of the blister machine with increasing temperatures to 150°C, and then at several temperature intervals, place the Thermex® between the seal tool to reveal the temperature profile of the entire seal area. Thermex® quickly and permanently changes color to indicate temperature distribution, and Topaq allows detailed digitized images to be obtained from the Thermex® sensor paper.
