Correct Load Containment: The Key to Effective Pallet Wrapping
If your pallet needs to be wrapped, it needs to be wrapped properly. Applying the correct load containment force consistently is the key to pallet wrapping. The purpose of wrapping your pallets is to contain and protect your goods during transit and storage in the most efficient and cost effective method.
What is Load Containment Force?
Film Layers x Wrapping Tightness = Containment Force
Containment force is the squeezing pressure that the film exerts on the load that it holds. Applying the correct load containment force is the key to effective pallet wrapping. More film revolutions doesn’t mean your load will be more secure. Thicker stretch wrap also doesn’t mean your pallet load is more secure. These are common misconceptions about pallet wrapping.
Why is correct load containment so important?
Over 50% of damage is due to ineffective pallet wrapping. Your pallet loads may seem secure when they leave your warehouse but in what condition do they arrive at their destination?
Inconsistent load containment force or poor load-to-pallet bond are the most common reasons for pallet load failure. These preventable damages to pallet loads cost businesses millions per year. During transit, the load undergoes a lot of stress, such as abrupt starting and stopping, vehicle vibration, sharp turns, etc. If the load on the pallet is not correctly contained, there is a high risk of it being damaged.
How to ensure correct pallet load containment?
Testing the containment force of your pallet load is the key to ensuring effective pallet wrapping that will survive transit and rough handling. These tests give you the accurate containment force of your wrapped pallet load.
Like a chain, the containment force of a load is only as strong as its weakest point. Loads are most likely to fail when the containment force is below the minimum required level. That’s why it is important to test your containment force in three vertical positions of the pallet:
Top: 50 mm from top, 560 mm from right side of pallet
Bottom: Half the height of pallet from top, 560 mm from right side of pallet
Middle: 230 mm above lowest film cable, 560 mm from right side of pallet
Reinforced stretch wrap increases containment force by 60%
The reinforcements of PerformX Stretch Wrap act like ropes around the pallet, holding the load secure. As a result, the load security of the pallet is 60% more than a conventional stretch film. As well as improving load containment, these reinforcements mean less rotations are required to wrap the pallet, reducing stretch film usage and wrapping time. The Omni PerformX unbreakable reinforced stretch film is the world’s most innovative, effective and sustainable pallet wrapping solution.
Load Containment Force Recommendations
Different types of loads require different amounts of containment force. To ensure that you have a stable and secure pallet load, it is important that suitable containment force is applied to the pallet. The examples below highlight this point:
- Very light loads (0–200 kg): CFR = 0.9 to 2.3 kg
- Stable mid-weight loads (200–500 kg): CFR = 2.3 to 3.2 kg
- Heavy unstable loads (500–700 kg): CFR 3.2 to 5.5 kg
- Very unstable loads (750–1000 kg): CFR 5.5 to 9.1 kg
