Clamshell Packaging Machine
A turnkey clamshell section: clamshells are denested and registered, product is loaded manually or robotically, and each pack is positively closed before moving to labeling and case packing.
This clamshell packaging machine automates both low- and high-speed production for fresh produce, salads, bakery goods, and similar items. It automatically de-nests clamshells, fills them accurately using manual, volumetric, multi-head weigher, or other custom filling methods, closes the lid with a press-to-lock action, and can add tamper-evident sealing.
An ergonomic conveyor or carrier system carries trays smoothly through the line, supporting manual loading where needed or moving clamshells between stations automatically. This keeps workflow efficient and adapts easily to different products and setups.
Compact but sturdy, the system boosts line output, cuts labor needs, and maintains consistent packaging quality. Its hygienic design suits food-grade environments and allows fast changeovers between clamshell sizes and styles.
From delicate salad greens to denser items like sprouts, this machine offers the flexibility, speed, and consistency food producers need in one automated package.
