Plastics : Reducing Film usage in warehouses and reducing costs

If a warehouse is spending heavily on stretch film, a 20–40% cost reduction is often achievable without reducing load security (how pallets are kept stable and safe during handling and transport). 

Most of the savings come from using less film, improving wrapping methods, and reducing waste.

1. Use the correct stretch film grade:

Many warehouses use film that is thicker than necessary:

• Review the weight and shape of your loads.
• Switch from standard film to high-performance or pre-stretched film where appropriate.
• A thinner, stronger film can provide the same holding force with less material.

2. Optimize Stretch Percentage:

Stretch film is designed to stretch before it is applied:

• Many operators apply film with little stretch
• It results in wasting material.

Good practices for saving film:

• Use film that can stretch 200–300%.
• Train operators to maximize safe stretch levels.
• Adjust machine settings regularly.

It results in:

• Less film used per pallet.
• Better load containment.

3. Reduce Excess Wraps:

Many pallets receive more wraps than necessary.

The below information should be monitored:

• Number of bottom wraps
• Number of top wraps
• Revolutions around the pallet

Example:

Before:

• 5 bottom wraps
• 5 top wraps
• 12 revolutions

After testing:

• 3 bottom wraps
• 3 top wraps
• 8 revolutions

This alone can reduce film consumption by 15–25%.

4. Upgrade Wrapping Machines:

Older machines often have poor tension control.

• Modern stretch wrappers:
• Apply consistent tension
• Use less film
• Reduce operator error

Although there is an initial investment, many warehouses recover costs within a year through film savings.

5. Standardize wrapping procedures:

Different operators often wrap pallets differently.

Create a standard operating procedure (SOP):

• Which film to use
• Number of wraps required
• Machine settings
• Load-specific requirements

Consistency prevents unnecessary film usage.

6. Improve pallet stability:

Unstable loads require extra wrapping.

The below elements need to be improved:

• Pallet quality
• Carton stacking patterns
• Corner boards:  packaging components used in palletizing to protect the edges and corners of products or cartons.
• Slip sheets: are sheets of cardboard, plastic, or fiber placed under or between products on a pallet to help stabilize and protect the load.

A stable load needs less film to stay secure.

7. Monitor Film Usage:

Track the below key metrics:

• Film used per pallet
• Film cost per shipment
• Film consumption per month
• What gets measured gets improved.

8. Reduce Film Waste:

Common sources of waste:

• Damaged rolls
• Film tails left hanging
• Incorrect machine settings
• Operator mistakes

Simple housekeeping and training can reduce waste by 5–10%.

9. Conclusion:

To use stretch film optimally in warehouses, the below elements need to be taken into consideration:

• Film optimization
• Proper machine settings
• Operator training
• Standardized wrapping procedures

The combined results of these methods often deliver the target 20–40% reduction in stretch film costs.
