SEALS for THE FOOD INDUSTRY

Custom Die-Cut Seals for the Food Industry – High Quality and Safety

The food industry requires not only precision, but above all the use of materials that meet the highest safety standards. In this context, seals die-cut on knife plotters from certified materials such as FDA silicone, FDA metal-detectable silicone, FDA EPDM, MVQ FDA and EPDM FDA foams, as well as WRAS-certified materials, have become a key solution.
In this article, we present the advantages of these materials, their applications, and additional products we can offer, such as ready-made gaskets, O-ring cords, O-rings, and full sheets.

FDA Certification – A Guarantee of Safety in Contact with Food

The FDA certificate (U.S. Food and Drug Administration) is a global standard that defines requirements for materials intended for contact with food. To obtain this certification, a material must be non-toxic, resistant to the migration of harmful substances, and chemically stable when in contact with food products.
As a result, FDA-compliant materials are safe for consumer health, making them indispensable in the food industry.

WRAS Certification – What Is It and Why Is It Important?

The WRAS certificate (Water Regulations Advisory Scheme) is an international confirmation that a given material, product, or component complies with regulations concerning the safety of water intended for human consumption. This certification is particularly required in industries where materials come into contact with service water, including drinking water.

What Does WRAS Certification Mean?

WRAS certification confirms that a material:

• Does not negatively affect water quality: it does not alter taste or odor, nor introduce harmful substances
• Is safe for health: it does not release toxic substances or contaminants
• Meets hygiene and safety standards: complies with drinking water regulations

Materials that have obtained WRAS certification have been tested and approved for their chemical, microbiological, and physical neutrality toward drinking water.

Where Is WRAS Certification Applied?

WRAS certification is essential in many sectors, including:

• Food industry – water supply installations for production processes, food machinery, and cleaning systems
• Water supply industry – pipes, valves, and seals used in drinking water transmission
• Construction – installation equipment and materials such as pumps, taps, and boilers in contact with service water
• Cooling systems – applications requiring high water quality, e.g. in food and beverage production

Which Materials Can Obtain WRAS Certification?

Materials commonly certified according to WRAS include:

• Rubber materials such as EPDM, silicone, and NBR
• Plastics used in piping systems and fittings

Why Is WRAS Important for the Food Industry?

For the food industry, WRAS certification guarantees that applied components do not negatively affect the quality of water used in production processes. This helps prevent water contamination and ensures compliance with sanitary regulations and safety standards.

Combined with FDA certification, WRAS provides comprehensive assurance that a material is suitable for both food contact and contact with water used in food preparation.

Metal Detectability – Additional Production Safety

FDA metal-detectable silicone is a material enhanced with special additives that allow it to be detected by metal detectors used on production lines. This minimizes the risk of finished product contamination with fragments of sealing elements, which is crucial for maintaining the highest food safety standards.
In the event of damage or failure of a sealing component, detection systems allow quick identification of the issue, eliminating potential hazards.

Sealing Materials for the Food Industry

We offer die-cut seals made from various materials that meet the specific requirements of the food industry:

1. FDA Silicone

• Resistant to high and low temperatures (from –60°C to +230°C)
• Resistant to fats, oils, and many chemicals
• Ideal for applications requiring direct food contact on production lines
• Detectable by metal detection systems
• Particularly useful in mass production where contamination risk must be minimized
• Resistant to steam, hot water, and chemicals
• Excellent for use in humid environments, such as cleaning equipment
• Cellular foams with high elasticity and resistance to deformation
• Used for sealing oven doors, cold rooms, and packaging machines

2. FDA Metal-Detectable Silicone

3. FDA EPDM

4. MVQ FDA and EPDM FDA Foams with WRAS Certification

5. Food-Grade Rubber

What Is Food-Grade Rubber?

Food-grade rubber is a category of rubber materials designed for contact with food. It is characterized by:

• Chemical resistance – does not react with food products
• Elasticity – excellent resilience over a wide temperature range
• Safety – meets FDA requirements, ensuring neutrality to consumer health
• Seals in food processing machinery
• Insulation mats on production lines
• Vibration dampers in processing equipment

Applications of Food-Grade Rubber

6. O-Ring Cords and O-Rings

In addition to die-cut seals, we also offer:

• O-ring cords – for individual on-site customization, including metal-detectable versions
• O-rings – ideal for precise applications in valves and pumps
• FDA and WRAS silicone and EPDM sheets – for further processing, including custom cutting

Applications of Seals in the Food Industry

Our die-cut seals made from the above materials are used in:

• Packaging machines – ensuring tightness in vacuum and thermal processes
• Production lines – isolating mechanical components and preventing contamination
• Ovens and cold rooms – resistance to extreme temperatures enables long-term operation
• Cleaning systems – high chemical resistance valued in CIP and SIP installations

Thanks to our range of die-cut seals manufactured on knife plotters from certified materials, the food industry gains not only reliability but also compliance with the highest safety standards. Metal detectability, cutting from FDA silicone or EPDM sheets, as well as the supply of O-rings and O-ring cords, enable comprehensive solutions for production lines.
