How Much Stretch Wrap Do You Need Per Pallet?

"How much stretch wrap do I need per pallet" is really a cost question. Film is bought by the roll but consumed by the pallet, so the number that matters is metres of film per load — and that changes with load height, film thickness, how many revolutions your operator or machine applies, and how much the film is stretched before it touches the load.

1. The five variables that decide film use

  • Load height. Taller loads need more wrap bands. A 1.2 m load and a 1.8 m load are not the same job.
  • Film width. Wider film covers more height per revolution, so fewer passes are needed.
  • Revolutions and overlap. Most warehouse wrap patterns use 50% overlap with reinforcement at the base and top. More overlap means more film.
  • Film thickness (micron / gauge). Heavier film weighs more per metre, so cost per pallet rises even if metres stay flat.
  • Pre-stretch. Film stretched before application covers more load per metre. This is where most savings live.

2. A worked example

Load: 48 x 40 in pallet, 1.5 m load height, uniform cartons, manual wrapping with 500 mm (20 in) hand film.

Pattern: two reinforcing bands at the base, spiral up with 50% overlap, two bands at the top.

Rough film need: perimeter of the load ≈ 4.5 m. With roughly 8-10 effective revolutions, that is about 36-45 m of applied film per pallet, before pre-stretch is taken into account. A 1,500 ft (≈457 m) roll therefore covers in the region of 10-12 pallets at that pattern.

Treat that as a starting estimate, not a specification. The reliable way to get your own number is to count rolls consumed against pallets shipped over one or two weeks — it captures your actual wrap pattern and operator habits, which no table can.

4. Where film gets wasted

  • Over-wrapping light loads — extra revolutions on stable cartons add cost and no containment.
  • Under-stretching by hand — pulling film off the roll without tension uses far more film for the same hold. Coreless pre-stretch film removes much of this variability.
  • Wrong grade on a machine — hand film on an automated wrapper breaks, and every break is wasted film plus downtime. Machine lines need machine grade film.
  • No base bands — loads that shift at the pallet edge get re-wrapped, which doubles film use on that load.

If you want this checked against your own operation, send us your pallet dimensions, load weight, wrap pattern and current roll spec — we supply hand, machine, industrial, colour and coreless film across Toronto and the GTA and will tell you where the film is going.

5. Questions we get asked

How many rolls of stretch wrap per pallet?

As a working figure, a standard 48x40 pallet wrapped in 18-20 micron hand film uses roughly one roll per pallet at typical overlap and revolutions, but the real number depends on load height, wrap revolutions and how much pre-stretch you get. Track rolls consumed per 100 pallets for a fortnight to get your own accurate figure.

Does thicker stretch wrap always mean fewer rolls?

No. Thicker film adds puncture resistance for sharp or dense loads, but on light uniform cartons a thinner film with good pre-stretch often gives the same containment for less material. Specify thickness against load profile, not habit.

What is pre-stretch and why does it matter to cost?

Pre-stretch is film elongated before it reaches the load. A pre-stretched or machine-applied film covers more pallet per metre of film, which lowers cost per pallet even when the roll price looks similar.
