Precision Clamshell Tray Sealing Machine

Product Overview

The Clamshell Tray Fill Close Machine is an advanced automated system engineered to streamline the filling and sealing of clamshell trays across food, daily chemical, and pharmaceutical industries. It integrates a high-performance multi-head combined scale dosing system, enabling fast, accurate product handling while supporting flexible size changes via quick-change parts—a critical feature for businesses needing to adapt to diverse packaging requirements. With a focus on efficiency and hygiene, the machine ensures high filling accuracy and a clean filling station, minimizing product waste and cross-contamination risks. Key components like the PLC control system (Siemens, Germany) and servo motor (Siemens, Germany) guarantee consistent performance, while its open-frame design simplifies maintenance—making it a reliable solution for scaling production without compromising quality.

Key Features

Pneumatic Control for Pneumatic Denester

The machine uses pneumatic control for its pneumatic denester, ensuring simple operation and low maintenance. This design eliminates complex mechanical parts, reducing downtime and making routine upkeep accessible for operators.

Servo Control for Precision Positioning

Dual servo control systems deliver unmatched precision in aligning clamshell trays and filling components. This prevents misalignment during sealing, enhancing product quality and reducing packaging defects.

Seamless Filling Design to Prevent Leakage

The seamless filling design creates a tight seal between the dosing system and tray, eliminating product leakage. This maintains a clean workspace and ensures each tray meets exact weight standards, critical for regulatory compliance in food and pharmaceuticals.

Quick-Change Parts for Flexible Sizing

With quick-change parts, the machine adapts to different clamshell tray sizes and package weights (200-1000g) in minutes. This eliminates the need for multiple dedicated machines, cutting equipment costs and optimizing production line space.

Multi-Head Combined Scale for Accurate Dosing

The integrated multi-head combined scale (compatible with linear weighers and volumetric cup fillers) ensures precise dosing of granular products—from mixed nuts to pharmaceutical powders. This feature is essential for consistent product quantity in every tray.

Open-Frame Drive Design for Easy Cleaning

The open-frame drive design allows fast dismantling and air-blow compatible cleaning, meeting strict hygiene standards in food and pharmaceutical packaging. This reduces the risk of cross-contamination and simplifies compliance with GMP (Good Manufacturing Practices).

HMI Touch Panel for Intuitive Operation

Equipped with a HMI touch panel (Siemens, Germany), the machine offers user-friendly control. Operators can adjust settings, monitor production speed (20-25 trays/min), and troubleshoot issues quickly, minimizing training time and human error.

Precision Mold Alignment with Custom Closing Tool

A custom closing tool ensures precise mold alignment during sealing, guaranteeing high sealing success rates. This protects clamshell trays from damage and keeps products secure during transportation and storage.

Applications

Food Industry

The Clamshell Tray Fill Close Machine excels at packaging food items like mixed nuts, dried fruit, candy, cookies, potato chips, coffee beans, pet food, frozen vegetables, cereal, and mixed oatmeal. Its hygiene features and high filling accuracy make it ideal for both ambient and frozen food lines.

Daily Chemicals Sector

For daily chemicals, it efficiently packages laundry detergent pods and granular cleaning products. The seamless filling design prevents chemical leakage, while quick-change parts accommodate different pod sizes and weights.

Pharmaceutical Industry

In pharmaceuticals, the machine handles granular powders with precision, adhering to strict industry standards. The open-frame design and easy cleaning ensure compliance with GMP, reducing contamination risks for sensitive products.
