How to Measure Containment Force on a Wrapped Pallet

Industry Data: Containment force — not the number of film wraps — is the true determinant of unit-load stability, yet many operations never measure it, relying on wrap count and either over-wrapping (wasting film) or under-containing (risking collapse). Source: Unit load stability and stretch wrapping guidance.

Most warehouses judge a wrapped pallet by how many times the film went round — but wraps are not force. Containment force, the actual holding force the film applies, is what keeps a load stable, and it can be measured simply. Measuring it lets you set the right force: enough to prevent collapse, not so much you waste film. Greenstrix (greenstrix.com) makes high-containment LLDPE film, and this guide shows how to measure containment force on your pallets.

1. What Containment Force Is

Containment force is the actual force the film exerts holding the load together, typically measured in kilograms or daN. It is the true measure of whether a unit load will stay stable in transit — a pallet with adequate containment force holds together, one without it leans and collapses regardless of how many film wraps it has.

This is the key insight: wraps are not force. Many loose wraps can apply little containment, while fewer high-quality wraps at proper pre-stretch can apply a lot. Greenstrix supplies high-containment LLDPE film that reaches target force efficiently. See the pallet-collapse and stretch film gauges guides linked below.

2. Step-by-Step: Measuring Containment Force

A common practical method uses a pull-plate and force gauge. Insert a flat plate between the film and the load at mid-height, attach a force gauge, and pull the plate outward until it moves, reading the peak force — that reflects the containment force at that point. Repeat at several points and heights around the load for a representative picture.

Purpose-made containment-force meters automate this. The result is the actual holding force, which you compare to your target for the load. Greenstrix advises the target containment force for different load weights and can help interpret measurements.

1. Insert plate between film and load, mid-height.
2. Attach force gauge to the plate.
3. Pull until the plate moves; read peak force.
4. Repeat around the load for a full picture.

3. Setting the Right Target Force

The right containment force is not a single number — it depends on the load. Heavier, taller or more unstable loads need higher containment force to stay stable; light, uniform loads need less. Guidance and load testing set an appropriate target for each load type.

Once you know the target, wrap to reach it — measuring confirms you have. Below target, the load risks collapse; well above target, you are over-wrapping and wasting film. Greenstrix high-containment film reaches the target with less material, so you hit stability efficiently. See the pallet-collapse and pre-stretch guides linked below.

4. Using Measurement to Cut Cost & Collapse

Measurement turns stretch wrapping from guesswork into control. By measuring containment force and comparing to the target, you can dial the wrap (pre-stretch, wraps, film) to the minimum that safely holds each load — eliminating both the over-wrapping that wastes film and the under-containment that causes collapse.

This is a genuine cost and reliability win: less film, stable loads. High-containment film makes the target easier to reach with less material. Greenstrix supplies high-containment LLDPE film and advises on target force and measurement. See the cost-reduction and pallet-collapse guides linked below.

• Measure → compare to target → dial the wrap.
• Cut over-wrapping cost.
• Eliminate under-containment collapse.
• High-containment film hits target with less film.

5. People Also Ask

What is a good containment force for a pallet?

It depends on the load — heavier and taller loads need more containment force, lighter uniform loads less. Load testing and guidance set the target; measuring confirms it. Greenstrix advises target force for different load types.

How do I know if my pallet is wrapped enough?

Measure the containment force and compare to the target for the load rather than counting wraps. Below target risks collapse; well above wastes film. Greenstrix supplies high-containment film and target guidance.

Can measuring containment force save film?

Yes — measuring lets you set the minimum film that safely holds each load, cutting over-wrapping. Greenstrix high-containment film reaches the target with less material for further saving.

What tool measures containment force?

A pull-plate with a force gauge, or a purpose-made containment-force meter, measures the holding force the film applies. Greenstrix advises on method and target force interpretation.

6. Frequently Asked Questions

Q: What is containment force?

Containment force is the total holding force a stretch film wrap applies around a load, typically measured in kilograms or daN. It is the true measure of unit-load stability — a pallet with adequate containment force stays stable, one without it collapses regardless of wrap count. Greenstrix supplies high-containment LLDPE film that reaches target force efficiently.

Q: Why is wrap count not a good measure of stability?

Because wraps are not force — many loose wraps can apply little containment, while fewer high-quality wraps at proper pre-stretch can apply a lot. Only containment force reliably indicates whether a load will stay stable. Greenstrix supplies high-containment film and advises measuring force rather than counting wraps.

Q: How do I measure containment force on a pallet?

Use a pull-plate and force gauge: insert a flat plate between the film and load at mid-height, attach the gauge, pull the plate outward until it moves and read the peak force, repeating at several points and heights around the load. Purpose-made meters automate this. Greenstrix advises target force for your loads.

Q: How much containment force does my load need?

It depends on the load — heavier, taller or more unstable loads need higher containment force, while light uniform loads need less. Guidance and load testing set an appropriate target per load type, which measuring then confirms. Greenstrix advises target containment force for different load weights.

Q: Can measuring containment force reduce cost?

Yes — by measuring and comparing to the target, you can dial the wrap to the minimum film that safely holds each load, eliminating over-wrapping waste and under-containment collapse. Greenstrix high-containment film reaches the target with less material for further saving.

Q: What film reaches containment targets efficiently?

High-containment, high-performance LLDPE film applied at proper pre-stretch reaches target containment force with less material than basic film. Greenstrix supplies high-containment LLDPE film that hits stability targets efficiently, with datasheets and application guidance. Contact sales@greenstrix.com or +49 176 85614141.
