Detail Information
Aluminum Foil Metal Detector for Food Packaging Line DD-220 series
Introduction
The DD-220 Aluminum Foil Pack Metal Detector is engineered specifically for products wrapped in aluminum foil or metallized film—where conventional metal detectors fail due to packaging interference. Built for seamless integration into conveyor-based production lines, it provides accurate ferrous metal detection even when products are fully foil-sealed.
Its multi-coil detection technology delivers stable sensitivity while keeping the machine compact, making it easy to fit into existing conveyors. The system supports multiple reject options—such as flap, pusher, or reverse belt—allowing manufacturers to match different product formats and line speeds.
Designed to meet IFS and HACCP requirements, the DD-220 offers reliable performance for final-stage inspection, including post-packaging checks, pre-shipment quality control, and integrated weighing or labeling stations. With a robust stainless-steel conveyor, modular structure, and simple cleaning access, it provides dependable contamination control for food, pharmaceuticals, and other industries dealing with foil-packed goods.

Aluminum Foil Metal Detector for Food Packaging Line Industry Applications
The DD-220 Series is engineered specifically for aluminum-foil packaging, metallized-film bags, retort pouches, and high-product-effect foods. With a dedicated high-frequency detection mode, it solves inspection challenges traditional metal detectors cannot handle.
Ideal for chocolate bars, baked goods, pastries, coated snacks, energy bars, roasted nuts, and mixed seeds packaged in aluminum foil or metallized-film wrappers.
Typical applications include:
Final inspection on horizontal flow-wrappers or pillow-pack machines
Detection of blade fragments or wire breakage after cutting processes
Stability against product effects caused by oil, cocoa, moisture, and sticky textures
This industry relies heavily on foil or metalized packaging, making high-frequency foil detection essential.
Designed for ready meals, microwaveable trays, MAP preserved foods, retort pouches, and aluminum-foil trays commonly used in modern prepared-food operations.
Use cases:
Post-sealing inspection for instant meals and ready-to-heat dishes
Metal contamination monitoring in foil trays or laminated pouches
Production lines handling high-salt or high-moisture products with strong product effect
A critical solution for high-throughput food factories demanding both speed and accuracy.
Suitable for smoked seafood packs, marinated meat pouches, frozen fillets in metalized films, processed meat trays, and vacuum-sealed foil-layer packaging.
Advantages in this industry:
High-frequency penetration through multi-layer barrier films
Compensation for salt, water content, and temperature variations
Reliable detection performance even on cold or frozen products
This makes DD-220 a strong choice for seafood and meat packers where conventional detectors fail.
Applicable to facial masks in aluminum-foil bags, cosmetic sachets (cream, gel, lotion), personal care wipes, and foil-layered sample packages.
Typical benefits:
Stable inspection for viscous, oil-based cosmetic products
Detection through metallic foil pouches without false-triggering
Compact integration with high-speed filling and sealing lines
A reliable solution for contamination control in personal care manufacturing.
