Technology explained
Impulse heat sealing is a precise and controlled process where seal quality depends on the interaction between temperature, time, pressure, cooling and material behaviour.
Under Technology explained, we explain the core principles behind impulse sealing and how modern sealing systems operate in practice.
The focus is on understanding the process rather than individual products.
You will find technical explanations covering sealing parameters, material influence, sealing bands, tools and system design.
The section also explains how RESISTRON® and CIRUS® technologies are applied to achieve stable, repeatable and energy-efficient sealing processes.
This knowledge supports correct system selection, process optimisation and reliable production performance.
Parameters for Heat-Sealing
Mutual dependence between parameters and material Heat sealing is not defined by a single setting, but by the mutual dependence between temperature,sealing force, time, cooling and material
Impulse Heat Sealing
Impulse Heat Sealing Impulse heat sealing is a process in which the heating cycle is synchronised with the machine rhythm. Each sealing cycle consists of
Constant Heat-Sealing
Constant Heat Sealing Constant heat sealing is a sealing method where the sealing bars are kept hot all the time. When the machine is running,
Sealing Principle with Different Bands
Selecting the correct heat sealing band is essential for achieving stable, efficient and repeatable impulse sealing.The sealing band defines how heat is stored, transferred and
The Best Way to Define Correct Sealing Parameters
To achieve a stable, repeatable, and high-quality impulse sealing process, both technical calculation and practical validation are required. This is why the combination of a
Heat seal testing
Heat seal testing Heat seal testing is carried out to verify and optimise sealing processes under production-relevant and controlled conditions. Materials are evaluated using controlled
