Meta description: Learn how to calculate stretch film cost per pallet step by step, including film weight, roll core deductions, pre-stretch ratios and hidden labour and damage costs, so importers and packers can compare quotes accurately.
Stretch film cost per pallet is the total film spend divided by the number of pallets successfully wrapped — not the price of a roll. A cheap roll with a short usable length, a heavy paper core and inconsistent gauge can cost more per pallet than a higher-priced roll of consistent machine film run at high pre-stretch. This guide sets out the calculation and lists the cost drivers that never appear on a quotation sheet.

Why the Roll Price Misleads Buyers
Stretch film is sold by roll but consumed by metre. Everything that sits between those two units is where purchasing decisions go wrong.
- Roll weight versus film weight. A nominal roll weight usually includes the paper core, so the PE stretch film you pay for can be 8–15% lighter than the label suggests.
- Usable length versus claimed length. Length is often stated at nominal thickness, so where the gauge runs thin the length may still be present but the protection is not.
- Thickness tolerance. A film specified at 20 micron with a wide negative tolerance delivers less material at the same price per roll.
- Pre-stretch capability. Machine film that runs at 250% pre-stretch uses far less film per pallet than hand film applied near its natural length.
Film should therefore be compared on cost per pallet — equivalently, on cost per kilogram of film actually consumed. Requirements may vary by application, market and applicable standard, and your wrap pattern affects the result as much as the specification does.
Cost per Pallet: The Formula Step by Step
- Measure the film applied per pallet. Count the revolutions in your wrap pattern, multiply by the pallet perimeter, and add film for the top sheet, base wraps and hand finishing. Record it in metres.
- Convert applied metres into film taken off the roll. If the film is pre-stretched on the machine, divide applied length by the pre-stretch ratio. Mass is conserved, so this gives the length consumed.
- Convert length into weight. For polyethylene film, kilograms = length in metres × width in metres × thickness in microns × 0.00092, the factor that expresses PE density so the units cancel.
- Apply your price per kilogram. Ask suppliers to quote per kilogram of net film weight rather than per roll, which removes core weight and gauge tolerance from the comparison.
- Add waste and changeover. Include film lost at start-up, on breaks, at pattern changes and on partial rolls left at shift end — a few percent on a good line.
- Divide total film cost by good pallets produced. Count dispatched pallets, not pallets started, so re-wraps are captured.
The result is one dollar figure you can compare between suppliers, gauges and wrap patterns.
A Worked Example
Take a 1200 × 1000 mm pallet with a perimeter of about 4.4 metres, wrapped with 20 revolutions plus roughly 3 metres for the top sheet and attachments. Applied film length is about 20 × 4.4 + 3 = 91 metres.
Hand film, 20 micron × 500 mm, applied at natural length. Film consumed from the roll is the full 91 metres. Weight = 91 × 0.5 × 20 × 0.00092 ≈ 0.84 kg. At an illustrative USD 1.60 per kg, film cost is about USD 1.34 per pallet.
Machine film, 20 micron × 500 mm, run at 250% pre-stretch. Film consumed from the roll is 91 ÷ 2.5 ≈ 36 metres. Weight ≈ 0.33 kg — roughly USD 0.54 per pallet at the same illustrative price.
The numbers are illustrative and use an assumed price; substitute your own quoted price and wrap pattern. The structure is what matters: a film that pre-stretches well can cut film cost per pallet by more than half before any negotiation, because you are buying metres of load containment rather than metres of film.
How Pre-Stretch Changes Cost per Pallet
Pre-stretch ratio is the length applied divided by the length taken off the roll. Hand wrapping applies film near its natural length, so the effective ratio is close to 1:1 and operator strength limits how thin the film becomes. A machine-grade PE stretch film is pulled through rollers running at different speeds, so ratios of roughly 150% to 300% are common on turntable and rotary arm wrappers.
Three consequences follow for buyers.
- Down-gauging becomes viable. Because pre-stretched film is thinner in the applied state, a thinner machine film can deliver the same containment force as a thicker hand film.
- Film grade matters more than price. A film that breaks at high pre-stretch forces operators to reduce the ratio and the saving disappears. Consistent gauge and good puncture resistance sustain high ratios.
- Machine settings are part of the calculation. Pre-stretch ratio, film force and revolutions determine consumption, so review them against real load performance instead of running one recipe for every product.
Pre-stretched film also narrows as it is drawn, so confirm the wrap pattern on a real load and re-check it after any gauge change.
Comparing Film Options on Cost per Pallet
| Film Option | Typical Thickness | Applied How | Main Cost Driver |
|---|---|---|---|
| Hand stretch film | 17–23 micron | Manual, near natural length | Operator technique and film length per roll |
| Machine film, standard | 17–23 micron | Turntable or rotary arm, moderate pre-stretch | Pre-stretch ratio and revolutions |
| Machine film, high performance | 12–20 micron | High pre-stretch, tight cast or multilayer blown structure | Gauge consistency and puncture resistance at high draw |
| Pre-stretched film | Down-gauged after drawing | Hand or machine, little further stretch | Usable length per kilogram |
Choose hand film when volumes are low, pallets vary in size or no wrapping machine is installed. Move to standard machine film once throughput is steady, and to thin high-performance machine film when film spend per pallet is large enough to justify validating a new specification.
Hidden Costs That Never Appear on the Quote
- Labour. Manual wrapping ties up an operator, and labour per pallet often exceeds film cost, so a film that lets the same operator wrap faster has real value.
- Film breaks and downtime. Every break stops the line, wastes the film already applied and adds a re-wrap. Cheap film with inconsistent gauge and low puncture resistance is a frequent cause.
- Load damage and claims. One damaged pallet can cost more than the film for hundreds of pallets, especially where pallet load stability depends on containment force.
- Roll changes and storage. Short rolls mean more stoppages and more partial rolls at shift end, while thinner film with more usable length per roll improves container and warehouse utilization.
- Recycling and disposal. Where markets levy fees or require recycled-content documentation, film spend is no longer only a purchase price question.
Common Purchasing Mistakes
- Buying on roll price without calculating cost per pallet.
- Comparing films that were never tested at the same pre-stretch ratio, on the same pallet, with the same wrap pattern.
- Accepting a length claim without checking roll weight, core weight and thickness tolerance.
- Choosing thickness by habit rather than by load weight, edge sharpness and stacking height.
- Specifying one film for every product, or ignoring machine settings and then blaming the film when consumption runs high.
What Information Should Be Included in an RFQ?
- Film type — hand or machine grade, blown or cast, and number of layers if relevant.
- Film structure and resin type, if the application specifies it.
- Dimensions — width, thickness, and either roll length or net roll weight.
- Core size and core material.
- Color, transparency and any printing requirement.
- Performance targets — pre-stretch capability, elongation, tack level (one-sided or two-sided) and puncture resistance.
- Test method, if your market or customer specifies one.
- Packaging — rolls per carton, pallet height and OEM branding.
- Order quantity in rolls, cartons, pallets or containers, plus trial order intention.
- Destination port, shipping terms, your machine model, normal pre-stretch setting and load description — pallet dimensions, load weight, carton type and stacking height, with a photo if possible.
How to Choose a Reliable Stretch Film Supplier
- Resin consistency. Ask which resins and tackifier systems are used and whether they change between orders. Resin substitution is the main cause of batch-to-batch variation in cling and puncture resistance.
- Production capability, thickness control and roll weight. Blown or cast extrusion, coextrusion layers, inline gauging, slitting and rewinding determine achievable tolerances. Request the tolerance on gauge and width, and confirm whether net film weight or gross roll weight is quoted, with core weight stated separately.
- Test reports and samples. Establish what batch testing covers and confirm the report refers to your gauge and batch; tensile and puncture behavior is commonly assessed against methods such as ASTM D882 and ASTM D5748. Test samples on your own machine at your pre-stretch setting.
- Customization and export support. Width, thickness, roll weight, core size, color and packaging are the fields most often customized. Confirm minimum quantities, container loading plans, labeling and documentation support.
- Complaint handling. Agree how short length, thickness deviation or film breakage complaints are investigated and resolved.
Be cautious with quotes far below the market cost of comparable resin and gauge, and with data sheets showing no tolerances or test conditions.
Frequently Asked Questions
How do I calculate cost per pallet if I do not know the film length used? Wrap one pallet and weigh the roll before and after — the difference captures slack, overlap and top sheet. Then ask suppliers for net film weight, core weight and thickness tolerance together.
Is thinner film always cheaper per pallet? No. A thinner film that breaks, or that requires more revolutions, can cost more. Compare on cost per pallet at equal containment performance.
Does pre-stretch really reduce film consumption? Yes. Applied film is drawn thinner, so a roll covers more pallets, provided the film holds high pre-stretch without breaking.
How many revolutions should a pallet get? Enough to hold the load without shifting or crushing, which depends on load weight, stability and stacking height. Validate the pattern on a real load.
How should stretch film be stored, and can it be customized? Keep rolls dry, shaded and away from heat, and rotate stock first-in, first-out. Width, thickness, roll weight, core size, color, printed branding and packaging are commonly customizable.
