Dishes that are fast and easy to prepare are very popular with consumers. Food being purchased based on the situation rather than to stock up continues to increase in prominence. As a result, the demand for convenience products is growing faster than average – whether quick snacks or complete meals that can be prepared with minimal effort. At the same time, consumer standards are rising in regard to the quality, freshness and taste of these products.
MULTIVAC offers a wide range of solutions for convenience products of all kinds: from typical ready-to-serve meals to menu components, snacks, vegetables, and fresh-cut products.
MULTIVAC solutions are available in all performance classes and automation levels. The portfolio includes machines with manual loading and operation as well as fully automated packaging lines. We integrate our tray packaging solutions into new or existing production environments with an understanding of the overall process.
In the case of packs with modified atmosphere, the atmosphere in the pack is replaced with a gas mixture that is matched to the product in order to maintain its form, colour and freshness. This modified atmosphere usually consists of carbon dioxide, nitrogen and oxygen.
The technically simplest solution is sealing of the trays without modified atmosphere. These packs protect the product from contact and mechanical influences but do not have any properties which extend shelf life.
For the production of EMAP packs, upper web films with microperforation whose permeability is adapted to the respiratory rate of the product are used. This enables an equilibrium atmosphere to be established, which extends the shelf life of delicate, respiring products such as fruit, vegetables, salads and herbs.

Packaging under vacuum extends the shelf life of products, since the biochemical degradation of the product is slowed down by the removal of the atmosphere. For the production of MultiFresh™ skin packaging, MULTIVAC also offers trays and MultiFresh™ skin films, which were developed jointly with leading film manufacturers and which ensure optimal packaging results.
As flat products can be slightly compressed during packaging, skin packs without product protrusion are particularly suitable for pressure-insensitive foods. For pressure-sensitive products as well as packs with product protrusion, we offer an attractive solution with MultiFreshTM Pro. The upper web encloses the product tightly and free of tension without affecting the shape of the product and without altering its decorations.
Peel corners can be used as opening aids for both inside- and outside-cut applications. The unsealed tab may be located within the tray contour or extended beyond the tray for a better grip.
All conventional trays made of plastic or other materials can be processed on MULTIVAC traysealers in a wide variety of shapes. When sealing, the upper web is optimally utilised with only minimal film trim lattice remaining.
Our powerful and reliable thermal transfer printers are used for inline printing of films on traysealers. The print contents typically consist of serial printing (texts and graphical
elements such as logos, barcodes, etc.) or of variable data:
Our systems for quality inspection are suitable for a broad scope of tasks, such as detection of foreign bodies, weight inspection and final pack inspection. They guarantee reliability and quality.
MULTIVAC offers IFS compatible, space-saving and highly efficient solutions for detecting contaminants of magnetic and non-magnetic metals.
X-ray inspection systems detect metallic and non-metallic foreign bodies, such as stones, glass, or bones. They can also be used for checking the completeness of the pack content. Packs which contain metallic components, such as clips, etc., can also be inspected using the X-ray inspection system.
Visual inspection systems for label, marking and pack inspection are integrated into MULTIVAC labelling and marking systems, or they are designed as stand-alone inspection solutions with a separate transport conveyor. Packs outside the tolerance range can be ejected. Camera-based systems are capable of doing even more: for example, they can check whether a product is positioned correctly in the pack, or whether a pack is completely filled.
