Metal Detectable Acetal is an acetal copolymer grade formulated with a metal detectable additive for food processing and packaging applications. This material allows plastic components or fragments to be identified by conventional metal detection systems used for quality inspection. Detection results can vary based on the sensitivity of the equipment.
As one of the engineered plastics available from Emco Industrial Plastics, Metal Detectable Acetal combines useful mechanical performance with a food-contact compliant composition. It provides a practical material option for manufacturers that need functional plastic components that can also be identified during production.
Metal Detectable Acetal is an acetal copolymer containing a specialized metal detectable additive. This allows the material to be identified by standard metal detection equipment commonly used to check food products for contamination.
For food processors, this provides another way to identify foreign material if a plastic component breaks or a fragment enters the product stream. Unlike conventional plastics that may require visual identification, this metal detectable plastic can be picked up by compatible detection systems.
Detection performance depends on the sensitivity and settings of the equipment being used, so the material should be evaluated with the specific inspection system used in your facility.
Metal Detectable Acetal provides the mechanical characteristics needed for functional components used in processing and packaging equipment. Its acetal copolymer base offers a combination of strength and stiffness, while its impact strength supports components exposed to routine handling and operating forces.
Key characteristics include:
These characteristics make Metal Detectable Acetal a practical choice among engineered plastics when both component performance and foreign-material detection are important considerations.
Food processing operations need reliable ways to identify potential contaminants during production. Previously, manufacturers often relied on highly visible colored plastics to make plastic components easier to locate if they entered a product stream.
Metal Detectable Acetal offers another option. This metal detectable plastic can be identified using standard metal detection equipment used for quality inspection. This can help reduce the risk of product containment issues and limit the potential financial impact associated with contaminated products.
Emco Industrial Plastics can help you select a suitable material based on your application and detection requirements.
Metal Detectable Acetal is intended for applications in the food processing and packaging industries where plastic components may be exposed to products or production processes. It can be considered for functional and machined components where mechanical performance and detectability are important.
Applications may include food processing equipment, packaging equipment, and other production components that need a detectable plastic material.
Before selecting a grade, consider the component's operating conditions, required mechanical properties, and the capabilities of your existing detection equipment.
