Why Understanding Your Load Profile Matters

When businesses experience load stability issues, the first question is often:

"Do we need a different stretch film?"

In reality, that's rarely the best place to start.

Before selecting a film, adjusting machine settings or changing wrapping patterns, it's important to understand the load itself. Every pallet presents its own challenges, and identifying the load profile is often the first step in developing an effective wrapping solution.

Not All Loads Behave the Same

At Load Integrity, we often categorise loads into three broad profile types.

Figure 1: Examples of common load profiles. While load type alone does not determine the correct wrapping solution, understanding the profile provides an important starting point when assessing load stability requirements.

Type A - Uniform Loads

These are the easiest loads to stabilise.

Products are generally stacked evenly, with flat sides and consistent dimensions throughout the pallet. The load has a predictable shape and provides a good surface for the film to contain.

Type B - Irregular Loads

These loads contain variations in shape, height or product positioning.

While still manageable, they require greater consideration when selecting film and determining the correct wrapping programme. Areas of the load may respond differently to containment forces, increasing the risk of movement during handling and transportation.

Type C - Complex Loads

These are often the most challenging applications.

Products may vary significantly in size, shape and weight distribution. The load can contain protrusions, voids or unstable stacking patterns that make it difficult to achieve consistent containment force across the pallet.

In these situations, simply applying more film is rarely the solution.

The Load Profile Is Only the Starting Point

While identifying the load type provides valuable information, it does not tell the whole story.

Other factors also influence load stability, including:

• Product characteristics

• Pallet configuration

• Stretch film specification

• Wrapping machine capability

• Distribution environment

• Handling methods

  
  

This is why a successful load stability assessment requires a complete understanding of the application rather than focusing on a single factor in isolation.

Prescribing the Right Solution

A useful comparison is the medical profession.

A doctor would not prescribe treatment before understanding the symptoms, carrying out an assessment and identifying the root cause of the problem.

Load stability should be approached in exactly the same way.

Selecting a stretch film without understanding the application can lead to unnecessary costs, poor performance and ongoing stability issues. The most effective solution comes from understanding the complete picture before making recommendations.

A Fact-Based Approach to Load Stability

At Load Integrity, we begin by understanding the load profile before assessing the wider packaging and wrapping process. This allows us to make informed recommendations based on evidence, application requirements and performance objectives rather than assumptions.

If you're experiencing load movement, product damage or uncertainty around film selection, contact us to discuss your application and arrange an initial assessment.
