What is flow wrapping?

Flow wrapping, also known as horizontal form-fill-seal (HFFS), is a high-speed packaging technique where products are wrapped in a continuous film, which is then sealed and cut into individual packages. This method is widely used across various industries for its ability to efficiently package products while ensuring maximum protection and hygiene.

Flow wrapping offers numerous advantages, making it a preferred choice for many manufacturers:

  • Efficiency: high-speed operations significantly reduce packaging time.
  • Product protection: seal integrity preserves product integrity and freshness.
  • Versatility: suitable for a wide array of products and industries.


Flow wrapping machines consist of several critical components:

  • Infeed conveyor: Transfers products into the wrapping area.
  • Film unwind unit: dispenses the wrapping film.
  • Sealing jaws: creates a reliable seal around the product.
  • Cutting unit: creates individual or dual packs.


Applications of flow wrapping

In the pharmaceutical industry, flow wrapping is essential for maintaining product integrity It is used to package items like blister packs and medical devices, ensuring they remain sterile and protected.

Pet food

For pet food, flow wrapping ensures products like treats stay fresh and free from contamination. The robust seals provided by our flow wrappers are crucial for maintaining product quality over time.

Food products

Flow wrapping is widely used in the food industry to package a variety of items such as meat, poultry, convenience foods, snacks and bakery products. The method provides a visually appealing and protective packaging solution that preserves the freshness and integrity of food products.

Flow wrapping process:

  • Feeding: products are placed onto the infeed conveyor.
  • Sealing: the wrapping film is sealed around the product by the centre seal and end seal jaws.
  • Cutting: the cutting unit slices the sealed film into individual packages.


Automation and technology

Modern flow wrapping machines are equipped with advanced technologies that enhance efficiency and precision. Features such as programmable logic controllers (PLCs) and touch-screen interfaces streamline operations. These machines can also be integrated with weighing and inspection systems to ensure consistent product quality and accurate packaging.

Materials used in flow wrapping:

Flow wrapping uses various film materials, each selected based on the specific requirements of the product being packaged. The primary materials used include:

Heat sealing film

Heat sealing films, typically made from polyethylene (PE), are used to create seals by applying heat and pressure. This method is cost-effective and widely used for many types of food products.

Cold sealing film

Cold sealing films are used for heat-sensitive items like chocolates and candy bars. These films use adhesive to create seals without the need for heat, making them suitable for products that can be damaged by high temperatures.

Composite film

Composite films consist of multiple layers of different materials, offering enhanced properties such as improved strength, barrier protection and visual appeal. These films are ideal for products requiring superior protection.

Mono film

Mono films are made from a single type of material, making them easily recyclable. They are often used when environmental considerations are a priority.

Paper-based wrap

Paper-based wraps are coated with a layer of plastic, providing a combination of the protective properties of plastic and the environmental benefits of paper. These wraps are commonly used for items like bread.

When selecting a flow wrapper, consider the following factors:

  • Product type and volume: choose a machine that can handle your specific product type and production volume.
  • Speed and efficiency: evaluate the machine’s speed to match your production needs.
  • Flexibility and adaptability: opt for a machine that can accommodate various product sizes and shapes.


Future of flow wrapping:

Sustainable packaging

The future of flow wrapping lies in sustainable practices. Eco-friendly materials, such as biodegradable films, are becoming increasingly popular, reducing the environmental impact of packaging.

Technological innovations

Emerging trends in flow wrapping include smart packaging, enhanced automation, and better integration with other systems. These innovations will continue to drive efficiency and adaptability in the packaging industry.

A modern essential

Businesses looking to optimise their packaging operations should consider the benefits of flow wrapping. It is a critical packaging solution that offers efficiency, product protection, and versatility. Its applications span across pharmaceuticals, pet food, and the food industry, making it an essential part of modern packaging operations.
