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 60–160 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

• Fresh Produce: Labeling clear plastic clamshells for strawberries, blueberries, cherry tomatoes, and salad greens.
• Bakery & Confectionery: Packaging for cakes, pastries, croissants, and cookies.
• Egg Trays: Rapid labeling on the top flat or curved surface of clear plastic or molded pulp egg cartons.
• Retail & Hardware: Clamshell blister packs for electronics, batteries, toys, and small tools. 

    FAQ:

1: How does the SKILT ELMD-SF60 handle labeling in cold-chain and damp packaging environments?
Answer: The SKILT ELMD-SF60 is built with a corrosion-resistant stainless steel chassis and heavy-duty components designed for wet sorting rooms. It features a specialized labeling head with high-torque micro-stepping drives that ensure consistent tension and precise label application, preventing label peeling or slipping caused by moisture on cold plastic clamshells.

 2: Can the ELMD-SF60 be integrated into existing fruit sorting and packaging lines in customer factory?
Answer: Yes. The ELMD-SF60 features a flexible, modular design and a highly intuitive PLC touch screen interface (supporting multiple languages). It easily syncs with standard optical sorting conveyors, automated checkweighers, and fruit grading systems commonly used by large agricultural exporters and manufacturers.
