Which clamshell machine should I automate first?

Start with the stage that limits output or requires the most repetitive labor. Closing, denesting and labeling are common first projects because they can be added to an existing line.

Can the machines handle more than one clamshell size?

Most systems can handle multiple formats with adjustable guides, recipe settings and format-specific tooling. We review your actual containers before confirming the changeover method.

Can new equipment connect to an existing packaging line?

Yes. Conveyors, controls and line speeds can be designed around existing fillers, weighers, inspection systems and downstream equipment.

Machines

Every Stage of the Clamshell Line.

Buy one machine to remove a bottleneck, or build a complete automated line. Every machine is designed to work with the others.

01 — Denest

Clamshell Denester

The first station of any automated clamshell line. A denester takes a stack of nested, empty clamshells and places them one by one onto the conveyor — open, square and correctly spaced for filling.

■Handles hinged PET, rPET and PLA clamshells
■Magazine holds several hundred containers for long unattended runs
■Servo or pneumatic pick with vacuum cups
■Tool-less guide adjustment for size changes

02 — Fill

Clamshell Filling Systems

Filling is where product meets package. We integrate multihead weighers, volumetric fillers and pick-and-place systems so every clamshell carries the right weight with minimal giveaway.

■Multihead weighers for berries, tomatoes, salads and snacks
■Timing hoppers synchronised to container indexing
■Gentle drop heights to protect delicate fruit
■Check-weigh and reject integration

03 — Close

Clamshell Closing Machine

Our flagship closing machine is a compact, stand-alone unit that accepts hinged lid containers with open lids, closes and locks them, and releases the package to downstream equipment — up to 80 containers per minute.

■Designed for tamper-evident hinged lid containers from 8 oz to 64 oz
■Accelerates and simplifies the closing process — up to 80 containers per minute
■Aluminum and steel construction with an electronic control system
■Compact footprint — easy to use, clean and maintain

04 — Label

Clamshell Labeler

Once closed, each clamshell needs branding, pricing and traceability. Our labeling stations apply top, bottom or wrap-around labels with accurate placement at line speed.

■Top, bottom and top-and-bottom label application
■Wrap-around and C-wrap options
■Thermal-transfer print-and-apply for dates, lots and PLU codes
■Label presence and barcode verification

05 — End-of-Line

End-of-Line Systems

The last feet of the line decide how efficiently product leaves the building. We supply case erectors, robotic case packers, case sealers, check-weighers and palletizers built around clamshell packs.

■Robotic pick-and-place case packing
■Automatic case erecting and taping
■Check-weighing and metal detection integration
■Case labeling and coding
