Frequently Asked Questions (FAQ)

The HFFS (Horizontal Form Fill Seal) machine is an automated packaging system that forms, fills and seals packages in a horizontal line – all happening from a roll of film that becomes the final packaging for the product. HFFS technologies are widely used in industries with high production volumes, such as food, pharmaceuticals and cosmetics. 

The types of HFFS machines are:

1. Single Line HFFS – One production line – one package is created in one cycle.

• Optimal for medium to large packaging.

Suitable for batch production with high quality.

1. Multilane HFFS – Machines that produce 2, 3 or more packages in one cycle.

• Perfect for small dose sachets, pharmaceutical and cosmetic products.

Work process:

• Foil unwinding: The machine feeds flexible packaging material (foil) from a roll.
• Forming: The foil is transformed into a package using a forming module – it can be flat (sachet), doypack (stand-up package) or non-standard shape.
• Filling: The product is dosed into the package with high precision – liquid, powder, granules, pastes.
• Sealing: Thermal or ultrasonic sealing. If necessary, hanging holes are added, as well as slits for easy and correct opening by the user.

Technical specifications:

• Production speed: Single Line – from 40-60 packages per minute; Multi line – 300+ packages.
• Filling volume: from 10 ml to 2L
• Product types: liquids, powders, granules, pastes.
• Supported materials: PET, PE, aluminium composites, barrier films.

Packaging types:

• Sachets – Small sachets with a 3 or 4-sided seal suitable for single doses of liquids, gels, powders or granules. Commonly used in cosmetics, pharmaceuticals, and food.
• Doypacks (stand-up pouch) – Freestanding pouches with a bottom. Ideal for products such as juices, spices, baby food, shampoo, and detergents.
• Zipper pouches – Reusable packages for more convenient consumption and storage. Perfect for coffee, dried fruit, nuts, supplements, and household products.
• Custom Shapes – Bottle-shaped, round, or shaped packages featuring an innovative look and strong marketing value. 
• With inserts and accessories – Options to add straws, dispensers, euro hanging slots, and clear windows.

Advantages of HFFS machine:

• Fully automated processes.
• High performance and speed.
• Material saving – roll film is cheaper than ready-made envelopes.
• Flexibility in packaging design and shape.
• Hygienic reliability – important for food and pharmaceuticals.
• Integration with quality inspection systems – marking, rejection of defective packages, serial numbers.

Each project starts with a technical consultation, followed by concept development, visualization (if needed), and production implementation. Contact our team for an individual quotation.

Quality, reliability, and sustainability are at the heart of every machine that comes out of our company. We use certified materials such as stainless steel, aluminium alloys, and technical polymers selected according to the specific industry – food, pharmaceutical, and cosmetic. Each component undergoes rigorous incoming inspection to ensure compliance with durability and safety standards.

The design and dimensioning of the structural components are carried out using specialised CAD/CAE software, allowing simulations and analysis of mechanical and thermal loads. This ensures stability, trouble-free operation, and extended service life of critical assemblies and parts.

Automation is a key element in our solutions: machines are equipped with PLC systems, servo motors, HMI panels, and intelligent sensors that control processes with high precision. This eliminates dependence on the human factor in operation and significantly reduces the risk of errors, especially in repetitive operations and high production volumes.

Operator safety and regulatory compliance are ensured through CE certification and built-in safety systems – emergency stop buttons, opening guards, access control and interlocks in case of incorrect operation.

Before delivery, each machine undergoes an in-house test and validation program, including simulations of real production cycles, verification of dosing accuracy, and visual inspection of the final result. In this way, the customer receives proven, robust, and verified equipment ready for integration.

To ensure safe transportation, the machines are packed in individual, reinforced transport packages tailored to the size, weight, and sensitive components of each device. We use wooden crates, protective padding, and vibration isolation where necessary. Packaging is designed to provide stability, moisture, and impact protection, and easy loading and unloading. Each shipment is marked and documented according to international safety and logistics standards.

Inventtech Ltd’s commitment does not end with the delivery – on the contrary, it starts there. We provide comprehensive support before, during, and after installation so that every machine is implemented correctly and operated with confidence by staff.

Installation and assembly are carried out by our qualified technicians who ensure the machine is correctly positioned, connected, and started up in a real production environment. After installation, we organize staff training that covers not only daily operation but also basic maintenance and safety procedures.

In addition, we offer periodic refresher courses for the employees who operate the machine, especially after the implementation of new functions, software updates, or when changing operators. This ensures a consistently high level of competence in operating the equipment.

Technical support is available by phone, email, or online, with the option of remote diagnostics and timely assistance if setup, optimization, or operating help is needed. If required, we can arrange an on-site visit to provide more in-depth consultation, set-up, or technical assistance.

We ensure a constant availability of spare parts and consumables so that a quick replacement can be carried out, with the possibility of express delivery. Each machine unit is designed to make maintenance easy, intuitive, and without interrupting the production process.

Every manufacturing investment has different objectives and dimensions – that’s why we don’t offer one-size-fits-all return formulas. Instead, we focus on delivering solutions that optimize processes, reduce costs, increase repeatability, and make staff’s working tasks easier.

Our machines are designed to be not just part of the production line, but an active partner in improving efficiency and quality. If you would like to discuss cost-effectiveness and applicability to your specific parameters, we are available for a one-on-one consultation where we will analyze your production needs, volumes, and goals.

Our machines are designed to integrate seamlessly into existing production lines, regardless of the platforms, controllers, or software systems used. This is achieved by using standardised communication protocols and architectures that allow easy connection to SCADA, ERP, and MES systems.

We incorporate familiar industry interfaces such as OPC UA, Modbus TCP/IP, Ethernet/IP and Profinet to ensure reliable communication between the machine and the central control system. This allows real-time data exchange, performance monitoring, statistics collection, and synchronization with other machines in the line.

Our solutions are fully compatible with the Industry 4.0 concept, supporting intelligent connectivity, remote diagnostics, predictive maintenance, and performance analysis (OEE). Machines can be part of a digital factory where each unit communicates with the others and with the central system, providing structured data on status, performance, and alarms.

Additionally, we cover the PackML (Packaging Machine Language) standard, which defines a unified model of states, commands and tags for packaging machines. This ensures operational consistency, easy integration between machines from different manufacturers, and faster implementation into existing lines. PackML is a recognized standard by OMAC and ISA, and is widely used in modern manufacturing environments focused on automation and digitalization.

Thanks to this architecture, our machines can be deployed as part of new or existing lines without the need for complex adaptations or additional software. This saves time, resources and ensures long-term compatibility with future technology upgrades.
