Heating system for sustainable moulded pulp packaging
In the packaging industry, producing sustainable and recyclable solutions remains a challenge. Traditional plastics are not environmentally friendly, and alternative materials often lack the required barrier properties and consistency in thickness.
Ensuring uniform thickness and optimal material adhesion
The cera2heat technology by Wattron enables precise digital heating for the lamination of thin plastic films (80 – 150 µm) onto fiber-based moulded pulp packaging. This technology ensures a consistent film thickness throughout the packaging, providing an effective barrier against gases, liquids, and fats. Additionally, the convenience of separating components for recycling enhances sustainability. The cera2heat system offers rapid heating rates of up to 100 K/s, a temperature range reaching 200°C, and a power density of up to 50 W/cm². With practically unlimited heating surfaces due to its modular design, it is compatible with tight-tolerance materials like polypropylene and recycled plastics. Integrated temperature sensors ensure precise process control, making it a reliable and efficient solution for industrial use.
Benefits
