In the food industry, product safety is an absolute priority. One of the most frequent causes of batch and supply recalls is accidental contamination with plastic fragments from components, tools, or processing lines.
To avoid these risks, detectable thermoplastic compounds have been developed, designed to be identified by metal detectors and X-ray systems, even when dealing with microscopic particles.
The Problem of Plastic Contamination in the Food Supply Chain
Every year, numerous food companies have to deal with product recalls from the market due to the presence of plastic foreign bodies.
These events not only lead to serious economic losses, but can compromise years of reputation and trust built with consumers.
Traditional plastics, in fact, are not detectable by standard quality control systems based on magnetic metal detectors. Even the smallest chip can go unnoticed and reach the end consumer.
Solution: the use of detectable compounds, designed to generate a magnetic or radiopaque response, allows for the interception of even the smallest contaminating particle during packaging or inspection of the finished product.
LATI MDT Detectable Compound Technology
LATI has developed the MDT (Magnetically Detectable Thermoplastics) range, a family of detectable thermoplastic compounds designed to ensure maximum food safety.
These materials are loaded with ceramic powders and magnetically active additives, capable of locally altering the magnetic field and making every plastic part detectable by metal detectors or X-ray systems.

| Detectability | Compatible with metal detectors and X-rays |
| Composition | Thermoplastic polymers filled with ceramic powders |
| Polymer base | PP, PA, PEEK, PPS, depending on application requirements |
| Food suitability | Compliant with European and international regulations |
| Processability | Injection molding, extrusion, or calendering |
| Mechanical strength | High even under dynamic conditions |
Applications of Detectable Compounds in the Food Industry
MDT compounds are used in a wide range of applications related to food production, processing, and packaging.
Examples of Producible Components
- Crates, containers, and lids for food processing lines;
- Conveyor belts and guides for handling systems;
- Maintenance tools and accessories (paddles, wrenches, pliers, spatulas);
- Fastening and closing elements in packaging machinery;
- Fittings and housings for sensors or valves in contact with food.
Thanks to their thermal and chemical stability, MDT compounds can also be used in process environments at high temperatures or with aggressive cleaning agents.
Performance in Extreme Operating Conditions
LATI offers MDT compounds formulated on different polymer bases to respond to specific operating conditions:
| Base type | Distinctive properties | Typical applications |
