Features

Using the same advanced technology as our standard models, this machine features automatic product learning and digital phase control to reliably detect tiny foil fragments and gilded particles.
Typical sensitivity is Fe ≥1.5 mm (in empty tunnel) with belt speeds up to 30 m/min. Like all GRAND machines, it meets food-safety standards: 304 SS frame, FDA PU belt, and IP65 washdown rating.
The system supports conveyor height/aperture customization and optional rejectors (e.g. air blast or flap). Common uses include inspecting packaged foods, pharmaceuticals, cosmetics, and textiles where metallic foil is present.

FAQS

1Why is a dedicated aluminum foil metal detector required for foil packaging?

Aluminum foil is inherently metallic and highly conductive. Standard metal detectors will interpret foil packaging as metal contamination, resulting in constant false alarms. An aluminum foil metal detection machine is specially designed to compensate for the conductive signal generated by foil or metallized film.

2What types of metal contaminants can an aluminum foil metal detector detect?

An aluminum foil metal detector is primarily optimized to detect ferrous metal (iron) contaminants. Non-ferrous metals and stainless steel are considered part of the “accepted background signal” due to the presence of aluminum foil packaging.

3In which industries are aluminum foil metal detectors commonly used?

Aluminum foil metal detectors are widely used in food, pharmaceutical, nutraceutical, cosmetics, and chemical industries. Typical applications include sachets, pillow bags, pouches, blister-related secondary packaging, and metallized film wrapping. They are especially critical in pharmaceutical and health supplement production, where foil packaging is standard and regulatory compliance requires reliable foreign-body inspection without false rejection.

4Can aluminum foil metal detectors be customized for different production lines?

Yes. Aluminum foil metal detection machines can be fully customized to match specific production requirements. Customization options include tunnel size, conveyor height, belt width, detection sensitivity, reject method (alarm stop, air blast, pusher), and control interface.
