MULTIVAC and Watttron turn to "Smart Heating" for producing sustainable packs

MULTIVAC at IFFA 2025 (Hall 12.1, Stand A 41): MULTIVAC pix-elHEAT forming system and MULTIVAC pixelSEAL sealing system

23.04.2025

Wolfertschwenden, 23 April 2025 – Efficient, reliable and sustainable: With its new matrix heating systems, MULTIVAC is perfecting the forming and sealing processes on its thermoforming packaging machines, and in doing so it is meeting the growing demand for sustainable packaging solutions. At this year's IFFA the company will be presenting the new MULTIVAC pixelHEAT und MULTIVAC pixelSEAL heating systems, which are supplied in cooperation with Watttron GmbH. They can be integrated into thermoforming packaging machines of all output categories.

MULTIVAC pixelHEAT system: More precision, less film consumption

The pixelHEAT matrix heating system enables high-quality thermoformed packs to be produced with up to 50 percent less material. Precise temperature control ensures that stable packs are produced with thinner films, as well as saving resources and energy. Heating pixels, which can be controlled individually, make it possible to achieve targeted material distribution during the forming process in the thermoforming packaging machine. The thinner plastic films are still able to achieve the desired pack stability. Thanks to the rapid and precise pixel heating of the film, up to 30 percent of the energy can be saved. Heating-up times of less than one minute accelerate the start of production and the conversion time between different formats. The heating system is particularly suitable for running recyclable films, such as mono materials – and in this way it supports the use of sustainable packaging concepts.

MULTIVAC pixelSEAL system: For a consistently high level of seal seam quality

The main feature of the pixelSEAL contour sealing system, which can be controlled digitally, is very precise temperature control for optimum sealing of thermoformed packs. High-quality seal seams ensure that hermetically sealed packs are produced. Sealing pixels, which can be controlled individually, provide an even and precise temperature distribution. The energy consumption during sealing can be reduced by up to 50 percent with the new heating system, and the heating-up time is particularly short. The sealing system also ensures that recyclable films are sealed perfectly.


Visitors to IFFA can convince themselves of the new technology and its potential for reducing film consumption: The new MULTIVAC pixelHEAT system will be shown at the trade fair using demo equipment and pack samples. Customers and other interested parties can also make an appointment at the MULTIVAC Innovation Center in Wolfertschwenden, so that they can receive individual advice, as well as a demonstration and sample production.
