TopCLOSE: Innovation in packaging

MULTIVAC introduces an innovative solution for sealing trays, specifically designed for packaging berries, showcased at Anuga FoodTec. This new method, TopCLOSE™, employs self-adhesive labels to seal trays in a simple, sustainable, and visually appealing manner, eliminating the need for a packaging machine. At the core of this system is the L 330 conveyor belt labeler, which automatically seals trays with labels specifically designed to withstand direct food contact, thanks to adhesive-free zones within the labels.

This technique is particularly suited for fruits and vegetables that do not require airtight or protective modified atmosphere packaging. The labels prevent products from falling out of the tray and are challenging to remove, contributing to the safety of the contents. Additionally, the labels can be equipped with a tear strip and a resealable feature, making them suitable for both rectangular and round trays. A significant advantage of this process is the ability to print labels with variable data and directly check the print, ensuring flexible and efficient production.

The L 330 conveyor belt labeler demonstrates the strength of the MULTIVAC TopCLOSE™ process by being able to seal up to 250 packages per minute, offering substantial cost savings compared to manual or automatic packaging solutions. The machine minimizes food waste and offers various automation options, such as tray denesters and product feed and discharge units, for a streamlined production line. The labeler is designed for easy operation and quick adjustments to different tray sizes and shapes, requiring no tools.

MULTIVAC's demonstration at Anuga FoodTec also showcases a plastic label with a transparent viewing window that seals berries in cardboard trays, keeping the plastic content below ten percent. Cutouts in the label ensure adequate air circulation, optimizing the shelf life of the berries. This process illustrates MULTIVAC's commitment to sustainability and innovation in the packaging industry, highlighting how technological advancements can contribute to more efficient and environmentally friendly packaging solutions.
