Stretch Film Packaging: Why Cost Per Pallet Wins

The roll price is the number most stretch film packaging decisions are made on, and it is the number that hides the answer. A cheaper roll that uses more film per pallet is more expensive than a dearer roll that uses less. The only figure that tells you what you are actually spending is cost per pallet — and that figure is the product of four variables that push against each other.

This page breaks that calculation apart, shows where the saving really comes from, and marks the point where saving film starts costing more in damage than it saves in material. Where that trade turns against you — loads failing at the corner before they fail anywhere else — is taken up in detail on our pallet stretch film page.

Key takeaways

– Cost per pallet, not cost per roll, is the only number that supports a switching decision.

– Four variables drive it — gauge, pre-stretch level, wrap count and load shape — and they offset each other. Thinner film plus more wraps is not a saving.

– Hand film versus machine film is a throughput question, not a quality question.

– Pre-stretch is where most of the real saving sits, and it has a ceiling: past the film’s yield point, containment force collapses.

– The cheapest pallet is rarely the one with the least film on it. Damage cost lands on a different budget line, but on the same business.

Cost Per Pallet, Not Cost Per Roll

Here is why roll price misleads. Two rolls at the same price are not the same amount of film: gauge, roll length and roll weight all move independently, so a cheap roll can contain fewer metres of usable film than a dearer one, and a film that stretches further before application covers more pallets per metre. Roll price tells you what you paid. It does not tell you what you used.

The conversion is simple and it is the only one worth doing:

• Film used per pallet — measured, not estimated from the machine’s wrap programme.
• Price per metre of applied film, not per metre off the roll, if your machine pre-stretches.
• Multiply the two. That is cost per pallet, and it is the number to compare across suppliers.

Once you have it, a dearer film that applies thinner and holds better often wins outright. A cheaper film that needs extra wraps loses. And the calculation also exposes the two questions roll pricing hides entirely: whether your wrap pattern is doing unnecessary work, and whether your pre-stretch is set to the film’s intended range. Both are free to fix.

The Variables Behind Cost Per Pallet

Four variables, and the reason cost-per-roll pricing is misleading is that they trade against each other.

Where the four differ is in what each one cancels out. A lighter gauge plus two extra wraps is not a saving — it is the same cost per pallet with less puncture resistance. Gauge, pre-stretch, wrap count and load shape each offset part of the others, and the table below shows what each one does to cost, to containment, and to the other three.

Variable	What it does to cost	What it does to containment	How it gets cancelled out
Gauge (film thickness)	Thicker costs more per metre	More puncture resistance, more holding force	A thinner film that needs extra wraps to reach the same containment gives back the saving
Pre-stretch level	Stretching film before application means less film per pallet	Up to a point, higher pre-stretch raises containment force	Past the film’s stable range, force falls and the load loosens
Wrap count	Linear: more wraps, more film	More wraps, more containment	More wraps on a thinner film is the classic false saving
Load shape	Irregular loads need more film to hold the same weight	Uniform, square loads hold with less	A poorly stacked pallet consumes film that no film change can recover

Read the table as a system, not a checklist. The commonest false economy in stretch film packaging is this sequence: switch to a lighter gauge, find that loads are loose, add two wraps to compensate, and end up paying the same per pallet as before — with less puncture resistance and a load that still shifts, because the extra wraps were never addressing the real problem, which was either the pre-stretch or the stacking.

The reverse also happens. A warehouse manager in Port Klang moved to a heavier gauge after a damage complaint, without changing wrap count or pre-stretch. Cost per pallet went up, and the damage continued — because the failure was at the corners, where film had been tensioned over a sharp edge rather than distributed. The material was never the variable.

Hand Film vs Machine Film

In stretch film packaging, this is presented everywhere as a quality comparison. It is not. It is a volume comparison, and the crossover point is throughput.

Hand film is applied by an operator walking around the pallet. It is the right answer when:

• Pallet count is low, or irregular enough that a machine would sit idle much of the day.
• Loads vary a lot in shape and height, so a fixed wrap programme does not fit.
• Capital is better spent elsewhere, and the operator is the flexible asset.

Its weakness is consistency. Hand-applied film varies with the operator, the pace, and the shift. Two people wrapping the same pallet will not use the same amount of film or achieve the same containment, and that variance is invisible in the roll price.

Machine film runs on a turntable, rotary arm or ring wrapper with a programmed pattern. It is the right answer when:

• Volume is high and consistent enough to keep the machine busy.
• You want the same wrap pattern on every pallet, which is what makes cost per pallet a controllable number rather than an average.
• You want pre-stretch to be a set value rather than something that depends on who is wrapping.

Machine film is formulated differently from hand film — it is designed to be stretched by the machine’s pre-stretch carriage at a controlled ratio, and it is not simply hand film in a bigger box. Using hand film on a pre-stretch machine underperforms, because the film is not being used the way it was engineered to be used.

The honest way to frame the decision: below a certain pallet count, hand wrapping costs less all-in; above it, the machine wins on both consistency and film consumption. That crossover is a throughput number, and it is worth calculating before buying either.

Hand and machine film are the two grades you will be quoted on, but they are not the whole of what a warehouse buys in roll form. Our packing roll manufacturing options cover the wider roll range for anyone consolidating supply across more than one film type.

Pre-Stretch: Where the Saving Actually Comes From

Within stretch film packaging, pre-stretch is the single largest lever on cost per pallet, and the least understood.

The principle: the film is stretched by the machine before it touches the load, so one metre of film from the roll becomes more than one metre applied to the pallet. You buy less film for the same coverage. That is the saving, and it is real.

What limits it:

• Every film has a stable stretch range. Inside that range, stretching stores force that holds the load — which is why a pre-stretched film can hold better than unstretched film of the same gauge. Beyond it, the film yields, force drops, and the load is loose regardless of how many wraps you add.
• The correct level is a film property, not a machine setting. Ask what pre-stretch range the film is engineered for and set the carriage to match. A generic carriage setting applied to a different film is the most common cause of “the machine film is worse than the hand film” complaints.
• Force matters more than coverage. A pallet wrapped with film at low tension looks fine and fails in transit. Containment force is what holds the load, and it comes from stretch within the film’s working range.

So the sequence for a genuine saving is: set pre-stretch correctly for the film, then reduce gauge if containment is still above what the load needs, then optimise the wrap pattern. Doing it in the opposite order — thin the film first, then hope the machine compensates — is how the false economy above happens.

Load Containment vs Film Use

There is a point where saving film costs more than it saves, and it is worth being explicit about where it is.

Under-wrapped pallets fail in three ways, and none of them appear on the packaging budget:

• Load shift in transit. Cartons move, stacks lean, and the pallet arrives as a leaning tower that the receiver may refuse.
• Product damage. Crushed cartons, scuffed cases, split sacks — written off at the far end, usually attributed to handling rather than to the wrap.
• Re-wrap and re-handling labour. A pallet that has to be rewrapped before it can be shipped costs operator time that no one tracks.

The judgement is not “use less film”. It is match containment to the journey. A pallet that travels from a factory to a distribution centre across town on a flatbed needs a different containment force from one going into a container for export, or one stacked three-high in a warehouse for a month. Load retention requirements are part of transit performance generally, and ISTA publishes transit test procedures for packaged products — worth referencing if you are arguing about whether a load is adequately contained.

The practical test: take your worst-case journey, not your average one, and validate the wrap pattern against it. If the average journey is what you wrap for, the tail of your distribution is where the damage comes from.

What to Measure Before You Switch Film

Switching on roll price is a coin toss. Switching on these three measurements is not, and they are the measurements that make any stretch film packaging quote comparable:

1. Film used per pallet. Weigh or measure it — pallets wrapped over a fixed period against film consumed, not an estimate from the wrap programme. This converts every future quote into cost per pallet.
2. Current containment force, or a proxy for it. If you cannot measure force, measure outcomes: damage rate, load-shift complaints, rewraps. A baseline is what tells you whether a change helped.
3. Load profile. How many pallets per week, what shapes, what stacking quality, and what journey. Irregular loads and poor stacking dominate film consumption more than film choice does.

Then trial any candidate film on your own loads, over enough pallets to see variance, and re-measure all three. A film that looks cheaper on paper and uses more per pallet is not cheaper. A film that uses less and produces two damage claims a month is not cheaper either.

Films behave differently by application, and the variables above shift again outside pallet wrapping — our agricultural film roll page shows how much a spec moves with use case.

Bring your pallet count and your current film spec, and we will work the cost-per-pallet comparison against your own numbers rather than a generic saving claim. Lead time and unit price depend on specification, print method and order quantity — confirm both with our sales team before ordering.

Six Weeks Later, on the Same Dock

Picture the same warehouse, two months after the switch. The roll price is on the invoice either way. What differs is the pallet standing at the far end of the dock.

One version leans. The stack has walked a couple of centimetres off the pallet edge, the corners have rubbed through, and someone is rewrapping it before the truck leaves — using the same film that was supposed to save money. Nobody books that time to the packaging budget. It turns up as labour, or as a claim.

The other arrives square. Same product, same journey, less film on it. The difference was not which roll got bought. It was the order the decisions were made in: pre-stretch set to the film first, then gauge, then wrap pattern — and that pattern validated against the worst journey rather than the average one.

That is the whole of cost per pallet. It is a sequence, not a purchase, and the three measurements in the section above are where the sequence starts.
