FERMAT BAG CLOSURE

The Future of Industrial Food Sealing

In packaging, success is not only about speed; it is also about the quality and security with which products are protected. That is why using a system that combines hermetic sealing, simplicity and reliability is key to achieving a professional result in every bag.

The patented hermetic bag closure system is an innovative solution that effectively addresses common packaging challenges, including loss of freshness, contamination and unreliable sealing.

This Spanish innovation combines airtight sealing, ease of use and durability, and is designed to protect food and products in all types of environments. It includes two complementary options tailored to different needs:
🔹 A reusable mechanical Fermat closure, ideal for households and small retailers, allowing bags to be securely sealed without tools.
🔹 An automatic insertion machine, engineered to integrate the same Fermat closure into industrial packaging processes with speed and consistency.

Both versions share the same goal: to enable a safe, reusable and effective sealing method that improves product preservation and optimizes operations in both domestic and industrial contexts.

The Manual Fermat Closure: The Reusable Solution Made Simple

At the core of this innovation is a mechanical Fermat closure designed in the form of a spiral. This configuration allows any flexible bag to be sealed quickly and easily, without adhesives or heat.

Its operation is intuitive:

• The section of the bag to be closed is inserted into the interior space of the Fermat closure.
• The closure’s curved geometry applies uniform pressure, compressing the bag and creating a hermetic seal.
• Two integrated hooks keep the Fermat closure firmly locked.
• To open the bag, simply release the hooks and remove the closure. It can then be reused as many times as needed.

Why This Closure Is Different

The patented hermetic bag closure system stands out for a combination of features that make it a practical, versatile and sustainable solution. Its main advantages include:

✅ Reliable hermetic sealing:
The Fermat closure’s spiral design applies even pressure along the bag’s surface, preventing air, moisture and contaminants from entering. This sealing capability keeps contents fresh and protected for longer.

✅ Unlimited reuse:
Unlike disposable systems, the Fermat closure is manufactured from elastic, resilient materials that regain their shape after each use. It can be opened and reapplied repeatedly without losing effectiveness.

✅ Ease of use:
No tools, heat or adhesives are required. Simply insert the bag into the Fermat closure and press until the hooks engage. To release, unhook and remove. This makes the system accessible to any user, even in non-specialized settings.

✅ Versatility:
The Fermat closure adapts to different bag sizes and thicknesses, whether plastic, paper or compostable materials. It is suitable for domestic preservation or small-scale commercial packaging.

✅ Sustainability:
Being reusable, it reduces the consumption of adhesive tapes, twist ties and other disposable closures, supporting more responsible and environmentally friendly practices.

✅ Professional appearance:
Although designed for ease of use, the resulting seal is neat and uniform, conveying a quality image that enhances product presentation in retail environments.

The Machine That Takes Industrial Sealing to the Next Level

For industrial environments and high-volume packaging lines, a dedicated machine has been developed to automate the insertion and sealing process of the Fermat closure.

This system is designed to integrate seamlessly into any production process. Its operation is fully automated:

• Automatic feeding: An external hopper continuously supplies Fermat closures.
• Bag preparation: A mechanism collects and compresses the bag’s open end.
• Insertion and sealing: The Fermat closure is positioned around the bag and hermetically locked with a pressure-activated mechanism.
• Release and continuation: Once sealed, the bag is released to continue along the production line.

Thanks to this solution, companies can maintain production speed and consistency without sacrificing sealing performance or reusability.

The Future of Industrial Sealing: Benefits Without Limits

Combining the reusable Fermat closure with automated insertion delivers tangible benefits that improve efficiency, quality and profitability across production lines. Key advantages include:

✅ Speed and efficiency:
The system is designed for continuous operation, with fast cycles synchronized with conveyor movement. This enables high throughput without interrupting workflow.

✅ Uniform and reliable sealing:
Each bag is sealed with consistent pressure and precision, ensuring airtight protection and reducing the risk of quality deviations or spoilage.

✅ Reduced operating costs:
Automation minimizes manual intervention, reduces human error, and cuts material waste. It also optimizes cycle times and allows staff to focus on higher-value tasks.

✅ Flexibility and adaptability:
The machine can be easily configured to handle different bag formats, materials and closure positions according to product requirements.

✅ Compatibility with existing processes:
Its modular design simplifies integration into existing packaging lines, leveraging current infrastructure without major investments.

✅ High-quality presentation:
Sealed bags have a clean, professional finish that enhances perceived product value and brand image.

✅ Reliability and low maintenance:
The robust mechanical design ensures stable performance over long production runs with minimal maintenance requirements.

✅ Sustainability and resource efficiency:
Using reusable Fermat closures decreases the volume of disposable consumables and helps reduce the environmental footprint of packaging operations.

The patented hermetic bag closure system is a versatile solution adaptable to diverse environments and requirements. Whether used manually or in an automated process, it provides benefits across a broad range of sectors:

🏠 Home and Small Retail:

• Food preservation (bread, biscuits, cereals, legumes, snacks) with extended freshness.
• Organized storage: neatly reseal opened bags to avoid spills and cross-contamination.
• Bulk goods packaging in specialty stores and health shops, enabling consumers to easily reseal at home.
• Professional presentation for artisanal products like pastries, confectionery and dried fruits.

🏢 Professional and Retail Use:

• Packaging of prepared foods requiring reliable sealing until consumption.
• Sale of fresh and frozen products in supermarkets and specialty retailers, with closures that withstand temperature fluctuations.
• Preparation of customized orders with reusable Fermat closures that customers can open and reapply conveniently.

🏭 Food Industry:
The automatic insertion machine is particularly suited for:

• Bakery and pastry production lines, where airtight sealing extends shelf life.
• Packaging of snacks, nuts, cereals and other dry foods needing moisture protection.
• Frozen product packaging in flexible bags with consistent, contamination-free sealing.
• Ready meal packaging in individual and family-size formats.

📦 Logistics and Distribution:

• Order preparation in warehouses and distribution centers requiring secure sealed bags until final delivery.
• Packaging of non-food products (small parts, textiles, industrial supplies) transported in flexible packaging.

🌿 Sustainability and Circular Economy:
Beyond its practical use, the system contributes to:

• Reducing single-use plastic waste.
• Supporting responsible consumption by extending packaging lifespan and minimizing waste.
• Providing a sustainable alternative to traditional tapes, twist ties and disposable closures.
