Tray Sealer for Halva Packaging

Tray sealer for halva packaging is a specialized packaging machine designed to seal halva (sesame-based confection) in trays using heat-seal film or foil lids to ensure freshness, hygiene, and extended shelf life. It is widely used by confectionery manufacturers producing block halva, sliced halva, or portioned halva desserts for retail distribution.

What It Does

This machine automates the final packaging step:

• Holds filled trays of halva

• Applies sealing film or foil lid

• Uses heat and pressure to create an airtight, tamper-evident seal

• Discharges ready-to-sell packs

⚙️ How It Works

1. Tray Loading

• Halva is manually or automatically placed into plastic or paper trays (PP, PET, or laminated paperboard).

2. Tray Positioning

• Trays are indexed into the sealing chamber or conveyor system.

3. Film/Lid Placement

• Roll film or pre-cut foil lids are positioned over the tray.

4. Heat Sealing

• Controlled temperature, pressure, and dwell time bond the film to the tray rim.

5. Cooling & Discharge

• Sealed trays exit the machine for labeling and cartoning.

Machine Types

1. Automatic Tray Sealer

• Conveyor-based continuous operation

• Can integrate with fillers and denesters

• Output: ~1,000–4,000 trays/hour

2. Vacuum / MAP Tray Sealer

• Removes air or injects gas (N₂/CO₂)

• Extends shelf life and preserves texture

• Ideal for export or premium packaging

✅ Key Features

• Strong, leak-proof sealing for oily halva products

• Adjustable sealing parameters for different films

• Food-grade stainless steel construction

• Quick mold change for multiple tray sizes

• Optional MAP/vacuum system

• No tray / no seal safety logic

Applications

• Sesame halva blocks

• Sliced halva portions

• Flavored halva (pistachio, chocolate, vanilla)

• Halva dessert trays with nuts or toppings

Important Tips for Halva Packaging

• Use oil-resistant sealing film due to sesame oil content

• Ensure clean tray rims for strong sealing

• Consider MAP packaging to prevent oxidation and extend shelf life

• Control product temperature to avoid oil migration during sealing
