Sealing consists in hermetically applying a film to a tray using a heating element. Performance is based on the machine + footprint + consumables (film and tray).
Remember: a sealed tray limits leaks and odors, ensures safe transport and enhances the value of your products – both in-store and on delivery.

Why choose sealing?
Health & Safety
- Total protection: tamper-proof tray after sealing.
- Zero leakage, zero odor: cleaner transport and storage.
- Ideal for delivery: secure multiple handling.
Economy & productivity
- Cost-optimized: film vs. lids.
- Space-saving: simplified storage.
- Fast: sealing in seconds.
Machine types: simple markers
| Type | How it works | For whom? |
|---|---|---|
| Manual | Operator pressure | Small volumes, controlled budget. |
| Mechanical assistance | Constant pressure via mechanical system | Better regularity, reduced fatigue. |
| Electric assistance | Motorized pressure + timer | Comfort, virtually no effort. |
| Automatic / semi-auto | Automated cycle (drawer/button) | High speeds, professional finishing. |
Useful options
- Die-cutting: contour-cut film for a clean finish.
- Vacuum and gas (MAP): to increase shelf life and preserve presentation.
- Customized imprints: adapt to your trays.
Consumables: the point that makes the difference
Successful sealing is highly dependent on film / tray / cavity compatibility (material, hot/cold use, barrier, oven, long shelf life, etc.).
💡 Good reflex
Before industrializing, test 2 to 3 references of trays and films under real conditions (cold, transport, lead times) to validate tightness and repeatability.
FAQ (SEO optimized)
Is sealing suitable for takeaway sales?
Yes, it limits leaks and odors, makes handling safer and improves the customer experience.
Do I need a specific footprint?
Often yes. The cavity must match the tray to ensure uniform pressure and a tight seal.
