Tailored Solutions Across the Dairy Spectrum

IMA’s technological portfolio is meticulously segmented to address the unique packaging requirements of different dairy product categories. The following sections provide an in-depth analysis of these solutions.

1. Butter and Margarine: Precision Dosing and Elegant Wrapping

Butter, a staple in households and the foodservice industry worldwide, presents specific packaging challenges. It requires machines that can handle a product with varying consistencies (from hard to spreadable), provide precise weight control, and create a tight, hygienic, and visually appealing wrap that protects it from oxidation and contamination. IMA’s solutions for this sector, primarily driven by IMA Benhil, are engineered for excellence.

Brick and Stick Wrapping Machines: IMA offers a comprehensive range of machines dedicated to dosing and wrapping butter and margarine into classic bricks and sticks. These machines cater to a vast spectrum of production needs, from artisanal producers to large-scale industrial dairies. The portfolio includes:

• Portion Flexibility: Machines are capable of handling single-serve portions (typically 5g to 20g) commonly found in restaurants and hotels, all the way up to family-sized blocks of 250g, 500g, and beyond. This flexibility allows producers to serve multiple market segments with the same underlying technology.
• Speed and Efficiency: Production outputs range from low-speed machines, suitable for niche or premium products, to ultra-high-speed wrappers capable of producing hundreds of portions per minute, ensuring efficiency for high-volume brands.
• The Perfect Fold: A hallmark of IMA’s butter wrapping technology is the ability to achieve a top-quality, precise fold. This is not merely an aesthetic consideration; a perfectly folded package ensures product integrity, prevents “butter fatting out” (the leakage of milk fat), and maintains a consistent brand image on the shelf. The machines achieve this through sophisticated mechanical engineering and precise control systems.
• Material Versatility: IMA wrappers are designed to work with a wide array of wrapping materials. This includes standard aluminium foil, which provides excellent barrier properties, and various paper-based solutions, including parchment paper and laminates, catering to the growing consumer demand for more sustainable and paper-like packaging. The machines can handle these different materials with minimal changeover time and consistent reliability.

Filling and Sealing Machines for Pasty Products: Beyond wrapped bricks, the butter and spreads category includes products like whipped butter, dairy spreads, and margarine that are filled into preformed containers. IMA’s FS (Fill and Seal) machines are designed for this purpose. They handle preformed cups or tubs in different sizes and shapes, filling pasty products with high accuracy. A critical feature for this product category is the adherence to high hygiene standards. These machines are constructed with easy-clean designs, often utilizing stainless steel and CIP (Clean-in-Place) capabilities to prevent bacterial growth and ensure product safety.

Form-Fill-Seal (FFS) for Portion Cups: For products like individual portions of whipped butter, spreadable cheese, or dairy-based dips, IMA’s FFS technology is ideal. These machines start from a reel of plastic film, form it into cups, fill the product, and hermetically seal it with a lidding material—all in one continuous, automated process. The benefits are numerous:

• Design Variety: They can produce a huge variety of cup designs, from simple round cups to sophisticated oval or rectangular shapes, enhancing brand differentiation.
• Material Options: Compatible with materials such as Polystyrene (PS), Polyethylene Terephthalate (PET), and Polypropylene (PP), allowing producers to choose based on clarity, rigidity, barrier properties, or recyclability considerations.
• Gentle Product Handling: The filling systems are designed to be gentle, preventing shear and maintaining the product’s desired consistency and air content, which is crucial for whipped products.
• Precise Cut-Off: The sealing and cutting mechanisms ensure a clean, precise cut-off between portions, resulting in a neat, leak-proof package that is easy for consumers to open.

2. Cheese: Comprehensive Solutions for an Immense Variety

The cheese category is arguably one of the most diverse in the dairy aisle, encompassing everything from soft spreadable cheeses to hard, grated varieties. Each type demands a specific packaging approach, and IMA’s range is correspondingly extensive.

Processed and Spreadable Cheese Lines: For products like cheese triangles, spreadable wedges, and rectangular portions, IMA Corazza provides complete, integrated lines. These lines handle dosing and wrapping with remarkable precision.

• Shape and Weight Flexibility: The technology accommodates a wide array of portion shapes—triangular, rectangular, square—and different weights, including mini-portions for snacking or catering. This allows for incredible product diversification from a single line.
• Preservation of Product Properties: The packaging process is designed to preserve the delicate properties of the cheese. State-of-the-art technology ensures that the cheese’s texture, flavor, and moisture content are maintained from the point of packaging to the point of consumption. The integrity of the package—typically a foil or laminate wrap—is paramount to prevent drying out or microbial contamination.
• Hot Fill and Cold Fill Systems: IMA’s portfolio includes solutions for both hot-fill and cold-fill applications. Hot-fill systems are used for many processed cheeses, where the product is filled molten and then cools within the package, creating a vacuum that extends shelf life. Cold-fill systems are for fresh, spreadable cheeses where heat would damage the product. This comprehensive range ensures the right technology for every cheese type.
• Secondary Packaging Integration: These primary packaging lines are often seamlessly integrated with dedicated secondary packaging equipment, which automatically collates the individual portions into cartons, trays, or flow-wrapped multi-packs, ready for distribution.

FS and FFS for Cheese Spreads and Dips: Similar to the butter category, cheese spreads and dips are also packaged in cups and tubs. IMA offers both FS machines for pre-formed containers and FFS machines for in-line cup formation. This provides producers with a choice: FS machines can offer more container design flexibility (e.g., using intricate, branded pre-made tubs), while FFS machines are often more efficient and reduce material storage space by using reels of film.

Packaging for Portioned, Block, and Shredded Cheese: This segment is where brands like IMA Gasti and IMA Ilapak shine with their horizontal and vertical packaging solutions.

• Horizontal FFS (Flow Wrapping): These machines are the workhorses for packaging portioned cheese (e.g., single-serve slices or sticks), entire cheese blocks, and pre-wrapped sliced cheese. The product is placed on a flat film, which is then formed around it, sealed along the top and back, and end-crimped. This creates a tight, pillow-style package that offers excellent protection and a large surface area for branding. Modern horizontal wrappers feature advanced controls for precise seal integrity and can handle a variety of films, including recyclable mono-material options.
• Vertical FFS (Bagging) and Weighing Solutions: For shredded, grated, and diced cheese, vertical form-fill-seal machines are the standard. These machines form a bag from a reel of film, fill it with the product (which is often dispensed from a multi-head weigher for extreme accuracy), and then seal it. Key advantages include:
  • High-Speed Operation: Capable of producing dozens of bags per minute.
  • Excellent Weight Accuracy: Integrated checkweighers ensure every bag meets the declared weight, complying with trade regulations.
  • Gas Flushing: Many of these systems can incorporate gas flushing (Modified Atmosphere Packaging – MAP), where the air inside the bag is replaced with a mixture of gases (like nitrogen and carbon dioxide). This dramatically extends the shelf life of shredded cheese by inhibiting the growth of aerobic bacteria and mold, and preventing clumping.

3. Liquid and Semi-Liquid Dairy: Creme Fraîche, Yoghurt, Desserts, UHT Milk, and Coffee Creamer

This category encompasses products with high hygiene requirements and, often, sensitive microbiological profiles. The packaging solutions here must prioritize accuracy, hygiene, and shelf-life extension. IMA Erca, IMA Fillshape, and IMA Hassia are the primary drivers of innovation in this area.

Outstanding Filling Accuracy: Whether using an FS machine for pre-formed pots or an FFS machine, a defining feature of IMA’s technology for this sector is its exceptional filling accuracy. For high-value products like yoghurt and desserts, even a small overfill represents significant product giveaway and cost over time, while an underfill risks regulatory non-compliance and consumer dissatisfaction. IMA’s fillers utilize precision piston, volumetric, or net-weight filling systems to ensure that every container has exactly the right amount of product.

Unmatched Design and Customization: The market for yoghurts, desserts, and creams is highly competitive, where packaging design is a key differentiator. IMA’s platforms offer countless customized and tailor-made possibilities for cups. This includes:

• Multi-Layer Desserts: Machines capable of depositing multiple layers of different products (e.g., fruit compote and yoghurt, crumble and custard) in a single cycle.
• Topping Inclusion: Systems for accurately placing solid toppings like cookies, chocolate flakes, or granola onto a product surface before sealing.
• Unique Shapes and Sizes: The ability to work with a vast array of cup sizes, from tiny 30g sample cups to large 1kg family tubs, and in various shapes to create a distinctive shelf presence.

Maximum Hygiene: SIP/CIP and Aseptic Technology: Hygiene is non-negotiable. IMA’s fillers for this category benefit from automatic, fully controlled Sterilize-in-Place (SIP) and Clean-in-Place (CIP) systems. These systems use hot water, steam, or chemical sterilants to automatically clean and sterilize all product-contact surfaces without the need for extensive manual disassembly, ensuring the highest levels of food safety and operational efficiency. Furthermore, IMA offers ultra-clean and fully aseptic solutions. Aseptic packaging machines sterilize the packaging material and the product separately in a sterile environment before filling and sealing. This allows products like UHT milk, coffee creamer, and probiotic drinks to be packaged without preservatives and have a shelf life of several months without refrigeration.

Filling Systems for Flexible Stand-Up Pouches: Reflecting a major packaging trend, IMA’s portfolio extends to filling systems for flexible stand-up pouches. These are popular for products like drinkable yoghurt, UHT milk, and creamers due to their lightweight, resealability, and efficient storage. IMA provides solutions for both standard pouches and those with spouts for easy pouring. These systems can be configured for ambient, ultra-clean, or aseptic filling, guaranteeing top hygiene design and product safety.

4. Turnkey Solutions and The Future of Dairy Packaging

IMA’s value proposition extends far beyond supplying individual machines. The true power of the IMA Group lies in its ability to leverage synergies and integrations to supply complete, turnkey packaging solutions.

Integrated Lines from Primary to End-of-Line: A “turnkey solution” means IMA can take responsibility for an entire packaging line, from the initial dosing of the product to its final placement in a shipping case. This includes:

• Primary Packaging: The core machines that first envelop the product (wrappers, fillers, FFS machines).
• Secondary Packaging: Equipment that groups primary packages, such as cartoners that load cups into paperboard cartons, or display box formers that create ready-for-retail displays.
• End-of-Line Equipment: Palletizers, case packers, and wrapping systems that prepare the finished goods for warehouse storage and transport.
