Food-grade materials and certifications for the food Industry

Food-grade materials and certifications for the food industry: Fluorten’s approach to compliance and safety

In the food and beverage industry, the selection of plastic materials and manufacturing processes is not merely a matter of technical performance; it is a fundamental requirement for safety, regulatory compliance, and long-term reliability. Plastic components and seals that come into contact with food must prevent contamination, maintain stable chemical and physical properties, and fully comply with international regulations.

For many years, Fluorten has served as a technology partner to designers, OEMs, and food-processing machine manufacturers, developing high-performance engineering polymer components and implementing manufacturing processes that comply with GMP requirements for food-contact surfaces. This integrated approach enables customers to confidently address audits, process validations, and applications within highly regulated production environments.

Industry context and requirements

The food industry is one of the most demanding sectors in terms of regulation and quality control. Components that come into direct or indirect contact with food products must comply with stringent standards, ensuring traceability, consistency, and safety throughout their entire lifecycle.

Regulations such as EN Regulation 1935/2004 in Europe, FDA regulations in the United States, and GB standards in China establish clear criteria for materials intended for food contact. However, selecting a “food-grade” material alone is not sufficient. The entire manufacturing process must be designed to prevent contamination, residue buildup, and quality deviations.

For engineers, designers, and technical buyers, this translates into a growing demand for suppliers capable of demonstrating documented compliance, application expertise, and a comprehensive understanding of materials, manufacturing processes, and quality controls.

Fluorten’s expertise and quality system

Fluorten addresses these requirements through a structured approach based on three key pillars: GMP-compliant processes, certified food-grade materials, and application expertise.

GMP compliance for food-contact surfaces

Fluorten complies with the applicable requirements of the GMP Protocol – Equipment with Food Contact Surfaces, implementing manufacturing procedures designed to minimize contamination risks throughout every stage of production.

This includes production flow management, machine cleaning procedures, machined-surface controls, and full batch traceability. GMP compliance is not simply a formal requirement; it is an integral part of Fluorten’s quality system, particularly for plastic components used in continuous and highly automated food-processing lines.

Certified food-grade materials for the food industry

Alongside its manufacturing processes, Fluorten carefully selects and utilizes certified food-grade materials that comply with major international regulations, including:

European Regulation (EC) No. 1935/2004;
FDA 21 CFR requirements for the U.S. market;
GB standards for the Chinese market.

The food-grade materials used by Fluorten are also BPA-free and do not contain intentionally added substances introduced during the manufacturing cycle.

Particular attention is given to the presence of NIAS (Non-Intentionally Added Substances), unwanted chemical compounds that may originate from raw-material impurities, chemical reactions, or degradation processes occurring during production. Monitoring and controlling these factors contributes to ensuring a high level of safety and compliance for food-contact applications.

An up-to-date list of certified food-grade materials is available in the “Food Grades Materials” document, providing designers and quality managers with a valuable reference during the design and validation phases.

Application expertise and technical support

Beyond regulatory compliance, Fluorten offers extensive expertise in designing PTFE and engineering polymer components for food applications. Solutions are developed with careful consideration of critical factors such as:

ease of cleaning and sanitization;
high-precision machined surfaces with low porosity;
dimensional and chemical stability throughout production cycles.

This approach helps reduce operational risks while simplifying maintenance and quality-control activities.

Applications: valves for food filling machines

A practical example of Fluorten’s approach to the food industry is its production of valves for food filling machines, an application where compliance, precision, and reliability are essential.

For more than 20 years, Fluorten has manufactured components for filling valves in both cylindrical and conical configurations, designed for processing a wide range of food products, including sauces, syrups, fruit juices, tomato concentrates, meat pâtés, jams, condensed milk, baby food, pet food, and chocolate creams.

These components are engineered for use in monoblock filling machines, including systems dedicated to edible-oil processing. All product-contact parts are manufactured from stainless steel or FDA-compliant non-toxic materials, while the entire production process follows GMP principles.

Key application benefits include:

low-porosity, chemically resistant materials suitable for food contact;
high-precision machining and smooth surface finishes that prevent residue accumulation;
gap-free interfaces between plastic and metal components to facilitate cleaning operations;
long-term reliability, even in intensive production environments.

In the food industry, compliance cannot be considered an optional requirement; it is an essential characteristic of both the product and the manufacturing process.

Fluorten addresses these challenges through an integrated system combining certifications, compliant materials, and controlled manufacturing processes, providing designers and OEMs with a reliable partner even in the most highly regulated environments.

Drawing on extensive experience in the food and beverage sector and a system-oriented quality approach, Fluorten continues to develop solutions that combine safety, performance, and reliability, helping manufacturers build compliant, efficient, and durable processing equipment.
