Rotary tray lidding machines are a type of fully automatic tray lidding machines. They are designed to handle a large volume of trays at high speeds.
The machine has a rotary table that moves the trays through the filling, sealing, and lidding process. The rotary table can have multiple stations for filling, sealing, and lidding, allowing for high production rates. These machines are suitable for large-scale production and are often used in the food and beverage industry.
Inline Tray Lidding Machines:

Thermoforming tray lidding machines are specifically designed to seal the lids onto thermoformed trays. Thermoformed trays are plastic trays that are made by heating and molding a plastic sheet to create a specific shape.
The machine first applies the lid onto the tray and then uses heat and pressure to create a tight seal between the lid and the tray. These machines are typically fully automatic and can process a high volume of trays per hour.
5.What Is the Working Principle Of Tray Lidding Machines?
- Tray Loading:
The machine's conveyor belt accepts the pre-formed trays and transports them down the packing process.
- Lid Dispensing:
Each tray's top is covered with a lid that is dispensed from a roll or stack.
The lid is then heated and compressed while being moved beneath a hot sealing plate or roller, which joins the tray and lid together.
Trimming off the extra material around the tray's and lid's edges creates a neat, polished seal.
The machine ejects the sealed trays and moves on to the following step in the packaging procedure.
Depending on the type of machine, the materials being used, and the unique packaging requirements, the exact operating principle of tray lidding machines can change. However, regardless of the type of tray lidding machine used, the fundamental idea of sealing pre-formed trays with lids is the same.
6.What Are the Components of Tray Lidding Machines?
Tray lidding machines are intricate pieces of machinery that use a number of different parts to seal pre-formed trays with lids. Some of the key elements of tray lidding machines are listed below:

8.What Is The Operation Procedure Of Tray Lidding Machine?
Here is a general overview of the operation procedure for a tray lidding machine:
Preparation:Ensure that the machine is clean and in good working condition. Check that the required materials, such as trays and lids, are available and properly loaded.
Set-up:Adjust the machine settings according to the tray and lid sizes. This typically involves adjusting the positioning of various components, such as the conveyors, sealing mechanisms, and sensors.
Loading:Place the empty trays onto the conveyor system of the machine. The trays move along the conveyor belt to the sealing station.
Lid Placement: The machine automatically picks up a lid from the lid magazine or stack and positions it correctly above each tray as it reaches the sealing station. This can be done using suction cups, mechanical arms, or other mechanisms.
Sealing: Once the tray and lid are properly aligned, the sealing process begins. Depending on the machine, the sealing can be done through heat sealing, pressure sealing, or other sealing methods. The sealing mechanism applies the necessary heat, pressure, or both to create a secure seal between the tray and the lid.
Inspection:After sealing, the machine may include an inspection system to ensure the quality of the seal. This can involve checking for proper adhesion, lid placement, or any defects in the trays or lids. If any issues are detected, the machine may reject the tray for manual inspection or adjustment.
Discharge: The sealed trays are then discharged from the machine, either onto another conveyor or into a collection area. The trays can be further processed or packaged as needed.
Maintenance and Cleaning:Regular maintenance and cleaning of the machine are essential to keep it in good working condition. Follow the manufacturer's guidelines for maintenance procedures, including lubrication, replacing worn parts, and cleaning the machine after use.
