Atlanta Drive France is launching new impulse heat sealing solutions on the French market from German manufacturer Ropex in order to respond to the issue of packaging durability. This franchise offers new opportunities in the process of closing plastic bags and especially in complex thermal insulation applications. The Resistron and Cirus pulse technologies from manufacturer Ropex benefit from standard and customized developments that can be integrated into machines for the food, medical, pharmaceutical, cosmetic, etc. industries.
Impulse closure, a very interesting alternative
Modern packaging must meet ever higher demands: high-performance machinery, special packaging applications, special requirements of packaged products, increasing production cost pressure, increasingly thin film types and therefore sensitive reasons, shortest possible closing time, minimum thermal stress for packaged products. , reduction of downtime for maintenance, replacement of worn parts or rework, … The sealing system and process repeatability must meet formidable challenges to be guaranteed.
Ropex gained worldwide recognition as a developer of sensorless temperature controllers for the sealing of thermoplastics by the pulse method – Resistron and then Cirus. An innovation that has also inspired many other types of temperature controllers offering many features and extensive connectivity. The impulse sealing process is a very interesting alternative to conventional sealing means (continuous heating); offers many advantages, especially in complex thermal insulation applications.
Ropex’s impulse sealing tools offer high temperature resolution in the active zone, minimal thermal impact – on both film and product – and high seal quality even with the smallest seal contours. Ropex works with partners on solutions that optimally combine the benefits of coated materials with the ability of impulse sealing – towards a total solution for packaging companies.
“Pulse heat sealing is a more precise and efficient technology than continuous heat sealing or ultrasonic sealing. It offers features that continuous closure does not,” explains Ropex.
Product designers, film producers and technology companies like Ropex work in R&D to provide innovative solutions to address the issue of packaging sustainability. This includes efforts to reduce the width of the film area to be sealed in order to save packaging material in the top, side and bottom sealing area. For tight welds, the sealing technology used must meet the highest sealing requirements, such as tensile strength and gas tightness, while providing an attractive visual quality. Ropex’s impulse sealing tools offer high temperature resolution in the active zone, minimal thermal impact – on both film and product – and high seal quality even with the smallest seal contours.
Meet the new standards
Ropex works with partners on solutions that optimally combine the benefits of coated materials with the ability of impulse sealing – towards a total solution for packaging companies. With the new European and international standards for the recycling of plastic waste and the production of recycled plastic, the production of plastic films will evolve towards more recycled materials. The European Packaging and Packaging Waste Directive, for example, recommends recycling 55% of plastic packaging by 2030.
This trend will also affect the composition of plastic films used in the packaging industry, and therefore affect the sealing characteristics of the films. To seal thermoplastic films, a certain temperature is needed to determine the processing window of the material. Ropex pulse sealing technology responds to these new constraints with precise temperature and time control.
Ropex Impulse sealing technology ensures that heat is generated only at the moment of contact of the film with the sealing medium and the actual demand for heat. Outside of pulse time, the insulation system remains cool: on-demand heat production optimized in terms of energy and CO2 footprint.
