The 3 parameters are equaly important for a perfect heat-sealing
Perfection depends upon absolute control over every factor that affects the process. In addition to using a reliable and consistent source of polymeric materials, the sealing or cutting process must be designed to assure absolute repetition of the temperatures, forces, and timing employed. This is easily accomplished if the proper system components and design are employed. It has been well established that the most dependable and precise system of production is the most cost effective.
ROPEX Resistron RES Impulse Heatseal Controllers provide a reliable and consistent heat sealing of polymeric materials for sustainable packaging. Perfect Seals… Every Time.
Temperature
The ideal temperature for sealing and subsequent cooling of a seal depends upon the formulation of the material. Some polymeric materials have a relatively wide window of opportunity for successful sealing or cutting. Other materials may have very narrow seal temperature window. Never the less, every material combination has an optimum Time/Temperature/Force combination that will produce the highest production rate with quality assurance. The challenge, therefore, is to determine the optimum combination of these elements. Skilled system designers at Ropex GmbH. and Jørgen Bork Electronic ApS do this every day.
Sealing Force
Sealing force is one of the key elements in achieving the perfect seal. This too, varies with the
nature of the material to be sealed and the optimum balance between time, temperature and force.
