1. Automatic Feeding Device (De-nester / Dispenser): operator loads a stack of clamshells/Egg tray box into the 4 feeding hopper and places them individually onto the conveyor belt using vacuum suction or mechanical grippers. With 2 / 4 /6 Channel feeding device optional depends on client labeling speed .
2. Conveyor System: High-precision transport belt equipped with guiding rails to keep the clamshells perfectly aligned during high-speed movement.
3. Labeling Head (Applicator): Powered by high-speed servo motors to dispense and apply labels precisely onto the moving containers.
4. Pressing/Smoothing Mechanism: Sponge rollers or brush systems that press the label firmly onto the clamshell surfaces to eliminate air bubbles and wrinkles. 
5. Automatic Collection Device (Stacker / Re-nester): Collects the labeled clamshells and automatically restacks them efficiently for bulk packing.

1. High Efficiency: Eliminates manual labor for feeding, labeling, and stacking, reaching speeds up to 60–150 containers per minute (depending on container size).
2. High Precision: Servo motor controls ensure labeling accuracy within ±1mm, even at maximum operational speeds.
3. Damage Prevention: Specially designed separation mechanisms handle thin plastic or paper pulp clamshells gently without cracking or deforming them.
4. Versatility: Adjustable guides allow the machine to handle various clamshell sizes and shapes 
5. Smart Integration: Often equipped with "No object, no labeling" and "Label missing alert" sensors to minimize waste. It can also integrate thermal inkjet printers for real-time printing of expiration dates and barcodes. 

    Common Labeling Configurations for Clamshells

      Depending on customer’s branding and security needs, high-speed machines are engineered for three main application styles :

1. Top Plane Labeling: A high-speed overhead dispensing head fires a label flat onto the top surface of the clamshell tray.
2. Top & Bottom Labeling: There with dual labeling heads on the machine conveyor , apply two stickers on clamshell top and bottom together.
3. C-Wrap / Tamper-Evident Labeling(This is specially suit for filled clamshell): A single long label is applied across the top lid, extends down the front opening, and wraps underneath the bottom base. This seals the clamshell shut, acting as a security and tamper-evident seal for fresh food retail. Learn More
