Not every pallet needs the same wrapping settings.
A pallet stacked with lightweight cartons needs a different approach from one carrying heavy bottles, bags or boxes of different sizes. Yet many warehouses use the same wrapping cycle for every load.
This might save time when setting up the machine, but it can lead to problems. Film may tear, cartons can get crushed, or products may shift during transport.
Adjusting your pallet wrapper settings to suit the load can help reduce film waste, improve load stability and keep products secure during handling and delivery.
The key is knowing which settings to change and when.
Light, Uniform Loads
Pallets stacked with cartons of the same size are generally easier to wrap.
The boxes sit evenly, the edges line up, and the weight is distributed across the pallet. Because the load is already stable, you usually don’t need excessive film tension or additional wrapping layers.
Recommended Settings
Film tension: Keep the tension at a moderate level. Too much pressure can crush lightweight cartons, especially those containing retail products.
Pre-stretch: Around 200% is a useful starting point for many light, uniform loads, provided the film and machine support it.
Bottom wraps: Start with three to four rotations around the base to help secure the load to the pallet.
Middle wraps: Apply two to three overlapping layers as the film moves up the pallet.
Top wraps: Finish with two to three rotations to help hold the upper cartons in place.
The goal is to keep the load secure without using more film than necessary.
If you notice crushed corners or damaged packaging after wrapping, check the film tension before adding or removing layers.
2. Heavy, Dense Loads
Heavy pallets need a different wrapping approach.
Products such as canned goods, bottled liquids, paint and raw materials place more weight on the pallet. Although these loads often have a lower centre of gravity, they can still shift during forklift handling or sudden braking.
The main concern is keeping the products together and preventing the lower layers from moving.
Recommended Settings
Film tension: Use higher tension than you would for lightweight cartons, but avoid stretching the film beyond its limits.
Film thickness: A thicker film, around 23 to 25 microns, can be a useful starting point for heavy loads.
Pre-stretch: Around 200% may work well, depending on the film’s specifications and the machine’s capabilities.
Bottom wraps: Apply five to six rotations around the base, making sure the film helps secure the load to the pallet.
Middle wraps: Use two to three overlapping layers through the main body of the load.
Top wraps: Finish with three to four rotations.
For heavy pallets, bottom reinforcement is particularly important.
If the lower cartons or products move during transport, the entire load can become unstable.
Some pallet wrapping machines also have a roping function. This gathers the film into a narrower band to provide additional holding strength around selected areas.
Avoid compensating for weak or unsuitable film by simply increasing the tension. This can cause more film breaks and interrupt production.
3. Mixed or Irregular Loads
Mixed pallets are often more difficult to wrap because the products don’t form a smooth, even surface.
You might have large cartons beside smaller boxes, bags stacked against rigid products or items with corners that stick out.
These uneven surfaces create gaps and pressure points where stretch film can tear.
Recommended Settings
Film tension: Use lower tension than you would for a uniform load. Excessive tension can pull the film tightly against protruding corners and cause punctures.
Film thickness: A film thickness of around 20 to 23 microns may provide additional protection against tearing.
Pre-stretch: Around 150% can be a starting point for irregular loads, depending on the film and machine.
Bottom wraps: Apply four to five rotations to secure the base.
Middle wraps: Use three to four overlapping layers, adding extra reinforcement where the load is less stable.
Top wraps: Finish with three to four rotations.
Add Extra Wraps Where They’re Needed
Not every section of a mixed pallet needs the same amount of film.
For example, if smaller cartons create an unstable area halfway up the load, you may need additional wraps around that section.
Many programmable pallet wrappers allow operators to add extra rotations at specific heights.
This helps reinforce weaker areas without applying unnecessary film to the entire pallet.
Corner protection can also help.
If products have sharp or rough edges, cardboard corner boards can provide a smoother surface for the film.
They also help distribute wrapping pressure more evenly and reduce the risk of punctures.
4. Tall or Top-Heavy Loads
Tall pallets require extra care because their height makes them more vulnerable to movement.
This is especially important when heavier products are stacked near the top.
During forklift handling, braking or cornering, the upper layers may shift if the load isn’t properly secured.
Recommended Settings
Film tension: Keep the upper section firmly wrapped without applying enough pressure to damage the products.
Film thickness: Around 20 to 23 microns can be a starting point, depending on the load weight and stability.
Pre-stretch: Around 180% may be suitable, provided the film and machine support it.
Bottom wraps: Apply four to five rotations to secure the base.
Middle wraps: Use two to three overlapping layers.
Top wraps: Apply four to five rotations to provide additional support to the upper layers.
Adjust the Turntable Speed
Tall loads can become unstable if the turntable rotates too quickly. Slowing the rotation gives the wrapping process more control, particularly when the upper cartons are not tightly stacked.
For pallets above approximately 1.6 metres, reducing turntable speed by 20% to 30% may be a useful starting adjustment. However, the appropriate speed depends on the load’s stability and the machine.
Consider Top Protection
If wrapped pallets are stored outdoors or transported where they’re exposed to dust and moisture, a top sheet may provide additional protection.
Some wrapping machines can apply a sheet of film across the top of the pallet.
This helps protect the upper cartons from dust, debris and light moisture exposure.
However, a top sheet alone doesn’t make a pallet fully waterproof.
Quick Reference: Pallet Wrapper Settings
The table below provides starting settings for different pallet loads.
| Load Type | Film Thickness | Pre-Stretch | Bottom Wraps | Middle Wraps | Top Wraps |
| Light, uniform | 17–20 microns | ~200% | 3–4 | 2–3 layers | 2–3 |
| Heavy, dense | 23–25 microns | ~200% | 5–6 | 2–3 layers | 3–4 |
| Mixed, irregular | 20–23 microns | ~150% | 4–5 | 3–4 layers, with extra wraps at weak points | 3–4 |
| Tall or top-heavy | 20–23 microns | ~180% | 4–5 | 2–3 layers | 4–5 |
Important: These settings are starting points, not fixed requirements.
The correct settings depend on the weight, shape and stability of your load, along with the film specifications and your machine’s capabilities.
Test the finished pallet before applying the same settings across an entire production run.
Three Things to Check Before Every Shift
Even when your wrapping settings are correct, equipment problems can affect the finished result.
A few quick checks before starting production can help prevent film breaks and inconsistent wrapping.
1. Check the Film Roll
Inspect the roll before loading it onto the machine.
Look for damaged edges, tears or uneven winding. These can cause the film to break or feed incorrectly during wrapping.
Also, make sure the film passes smoothly through the pre-stretch carriage.
A damaged roll can cause problems throughout the shift, even when the machine settings are correct.
2. Check the Turntable
Make sure the turntable is level and operating smoothly.
An uneven turntable can affect how the pallet rotates, leading to inconsistent film application.
If you notice the load leaning or moving during rotation, stop and check the pallet placement and machine condition before continuing.
3. Inspect the Pre-Stretch Rollers
Pre-stretch rollers help control how much the film stretches before it reaches the pallet.
Over time, these rollers can wear down or lose their grip.
When this happens, the film may not stretch as expected, even if the machine displays the correct setting.
Check the rollers for wear, damage or a glazed surface, and follow the manufacturer’s maintenance recommendations.
Final Thoughts
Getting the right pallet wrapping settings starts with understanding the load you’re working with.
Lightweight cartons may only need moderate tension and a few wrapping layers, while heavy, irregular or tall pallets often require additional reinforcement.
Instead of using the same settings for every pallet, adjust the film tension, pre-stretch, wrap pattern and turntable speed based on the products being wrapped.
It’s also worth checking the film and machine condition regularly. Small issues with the rollers, turntable or film roll can affect wrapping quality, even when the settings are correct.
The goal is to use enough film to keep the load secure without wasting material or slowing down production.
