Tray Sealing Machines for Vacuum and MAP Packaging
SIGITASPAK supplies tray sealing machines for hermetic sealing, vacuum and MAP (modified atmosphere packaging) of food in ready-made plastic trays and containers. Tray sealers are used for ready meals, meat, poultry, fish and seafood, cheese, salads, dates and sandwiches — wherever shelf life and pack appearance matter.
Fast selection logic for a tray sealer:
- Mode: sealing only, vacuum, or MAP with inert gas.
- Tray: size, depth and material; one or several formats on one machine.
- Output: manual loading up to 7 cycles/min or automatic sealing up to 16 cycles/min with up to 4 rows.
- Line scope: product dosing, coding, labeling, checkweighing, case packing.

FAQ
What is a MAP packaging machine?
A machine that replaces the air in the pack with a protective gas mixture before sealing. Our tray sealers and thermoformers work in MAP mode with an inert gas injection system.
Can one tray sealer work with different tray sizes?
Yes. Tray formats are changed with format tooling; the semi-automatic model has an optional format changeover set.
Do you supply tray sealers to Saudi Arabia, Oman and other GCC countries?
Yes. We supply equipment to the UAE, GCC countries, the Middle East and Africa from our Dubai office.
Do you provide installation and service?
Yes. Our service engineers in Dubai carry out installation, commissioning, maintenance and repair, and we keep spare parts for supplied equipment.
