Flow Wrap Optimisation – The Definitive Guide for UK Manufacturers

In the modern UK manufacturing landscape, the term ‘flow wrap’ has become synonymous with production efficiency. Whether you are a craft bakery in the Cotswolds or a high-volume medical supplier in Manchester, Horizontal Form Fill Seal (HFFS) technology is the engine behind cost-effective, high-speed packaging.

At Record Packaging Systems Ltd, we have spent over 50 years refining these systems to meet the rigorous demands of British retail and industrial standards. This guide explores the technical pillars of flow wrapping and how to optimise your line for maximum margin.

1. Understanding the Core: The Flow Wrap Process

Flow wrapping involves a continuous roll of film being shaped into a tube around a product, which is then sealed longitudinally (the fin seal) and transversely (the end seals).

As Robert Murphy, Sales Director at Record Packaging, explains:

“Selecting the right flow wrapper isn’t just about the machine’s specs; it’s about understanding the intricate needs of the product, the desired presentation, the production environment, and long-term operational goals. At Record, our role is to ensure we are providing customers with outstanding service and support to navigate these choices.”

2. Sealing Integrity: Rotary vs. Box Motion

The choice of sealing jaw is the most critical technical decision in your flow wrap setup.

• Rotary Motion: Ideal for uniform, high-speed products like cereal bars or biscuits. Our Record Superb rotary machines are designed for the ultimate throughput.
  
• Box Motion: For products requiring a hermetic, gas-tight seal or for taller items, box motion is essential. The “rectangular” path of the jaws allows for a longer dwell time, ensuring the film is bonded perfectly—a necessity for Modified Atmosphere Packaging (MAP).
  

3. Sustainability and the UK Plastic Tax

With the UK Plastic Packaging Tax and shifting consumer sentiment, transitioning to recyclable materials is a priority.

Andrew Murphy, Operations Director, who has been dismantling and perfecting flow wrappers since his teenage years at our Manchester headquarters, notes:

“One of the easiest ways to reduce packaging waste is to utilise recyclable mono-materials. However, these films often have a narrower ‘sealing window’ than traditional laminates. We work closely with our clients to adjust machinery—reducing seal widths or crimps—to ensure they protect the planet without sacrificing production speed.”

4. Real-World Application: Record Packaging Case Studies

Our expertise is best demonstrated through the bespoke solutions we’ve delivered across the UK:

• The ZIP® Fires Breakthrough: ZIP® required an environmentally friendly solution for firelighters. We love a challenge, and our team developed a system that accommodated sustainably sourced packaging materials while maintaining the high-speed throughput required for their global distribution.
  
• Fresh Produce & Shelf Life: For our clients in the fresh food sector, we utilise MAP (Modified Atmosphere Packaging). By injecting $CO_2$ or Nitrogen to displace oxygen, our flow wrappers significantly extend the shelf life of produce, reducing waste and increasing retail windows.
  
• Medical & Industrial: In high-precision environments, our “No Product, No Bag” sensors and print registration systems ensure that every pack is perfect, reducing material waste and ensuring compliance with stringent UK safety standards.

5. Optimising for Success: Maintenance and Support

A flow wrapper is a precision instrument. To keep your line running at peak efficiency, we recommend:

• Tension Control: Ensuring the film unwind system is calibrated to the specific gauge of your material to prevent “snaking” or film breakage.
• Preventative Maintenance: Regular jaw cleaning and blade replacement are vital.

Record Packaging provides full UK-based technical support, from initial consultancy to installation and ongoing servicing. We don’t just supply hardware; we provide turnkey systems designed to reduce your labour costs and maximise your margins.
