Stretch Film Gauge Chart: Gauge to Mil and Micron, Load Weights and Stocked Rolls

Updated August 22, 202614 gauges, mil and micron68 stocked rolls

100 gauge is 1 mil and each gauge is 0.254 micron, so the 80 gauge hand film most warehouses buy is 0.8 mil or 20 microns. The chart converts every common gauge, gives the load weight each is planned for, lists every stocked gauge, width and length with case pricing, and works out how much film one pallet uses at hand and machine stretch rates.

Gauge to mil and micron

Gauge is the North American unit for stretch film thickness: 100 gauge equals 1 mil, so 80 gauge is 0.8 mil, and each gauge is 0.254 micron. Most of the rest of the world quotes film in microns, which is why a spec sheet for imported film reads 20 or 23 microns where a US catalog says 80 or 90 gauge. The chart converts each common gauge and pairs it with the load weight suppliers plan around. Load figures assume a square, uniform pallet of cartons; sharp corners, protruding parts and mixed-size loads move a load up one or two gauges.

1 gauge = 0.01 mil = 0.254 micron. Load figures are the planning guidance used by film suppliers for a stable, uniform load; they are not test values.

Equivalent film is the exception to the gauge rule. A resin-engineered 63 gauge 'equivalent to 80' film performs like 80 gauge at lower thickness because it holds more stretch, and pre-stretched 37 and 40 gauge films are applied with almost no further stretch. Compare equivalents on holding force and puncture, not thickness; the mil to micron chart covers the arithmetic for every film type.

Stocked stretch film by gauge, width and length

Every combination in stock, cheapest product per combination. Hand film is 12, 15 and 18 inch; machine film is 20 inch on a 3 inch core. Cast film is clear and quiet with high cling on one side; blown film is tougher and holds better on loads with sharp edges but is louder to apply and less clear. The hand vs machine film page covers the crossover point.

68 stocked gauge, width and length combinations. Hand film is priced per case of 4 rolls; machine film per roll.

How much film a pallet uses

Film cost per pallet depends more on stretch than on gauge. A hand wrapper who stretches the film 50 percent uses roughly twice the length of a powered pre-stretch carriage at 200 percent, so the higher-gauge film often costs less per pallet on a machine than a lighter film does by hand. The table runs the arithmetic for a standard 48 x 40 pallet wrapped with 3 passes at the base, 2 at the top and a 50 percent overlap up the load.

18 inch film rising 9 inches per pass at 50 percent overlap. Film = passes x perimeter / 12, divided by (1 + stretch). Hand wrapping reaches 50 to 100 percent stretch in practice; powered pre-stretch carriages reach 200 to 250 percent.
Pallet (48 x 40, load height) Perimeter Wraps (3 bottom, 2 top, 50% overlap) Film used at 0% stretch At 150% stretch At 250% stretch
48 in 176 in 9 passes 132 ft 53 ft 38 ft
60 in 176 in 10 passes 147 ft 59 ft 42 ft
72 in 176 in 11 passes 161 ft 65 ft 46 ft

For a 1,500 ft hand roll, the 60 inch load at 100 percent stretch uses about 74 ft, or 20 pallets per roll. The same roll on a machine at 250 percent wraps about 35 pallets. Roll counts per pallet are the number to check when comparing a 60 gauge quote against an 80 gauge one: the heavier film costs more per roll and less per pallet when the wrapper is working hard.

Choosing a gauge

  • Uniform cartons, under 1,500 lb, hand wrapped: 60 or 63 gauge. Most ecommerce outbound pallets sit here.
  • Mixed cartons or anything over 1,500 lb: 70 to 80 gauge. 80 is the default gauge that most hand wrap is sold in for a reason: it tolerates the inconsistent stretch of hand application.
  • Sharp corners, drums, pails, metal parts, wire: 90 to 120 gauge blown film, or a lighter film with edge protectors under it.
  • Machine wrap: 63 to 80 gauge for most loads at 200 to 250 percent pre-stretch; 100 to 150 gauge only for loads over 3,000 lb or where the receiver specifies it.
  • Cold storage and outdoor: step up one gauge; film loses stretch and cling below about 40 F and UV breaks it down over weeks. The pallet cover guide covers weather protection on top of the wrap.

For stacking the load before it is wrapped, the pallet count table gives layers and heights for 60 box sizes.

Frequently asked questions

How many microns is 80 gauge stretch film?

20.3 microns. Gauge x 0.254 = microns, so 60 gauge is 15.2, 70 gauge is 17.8, 90 gauge is 22.9 and 120 gauge is 30.5 microns.

What does gauge mean in stretch film?

Thickness. 100 gauge equals 1 mil (one thousandth of an inch), so 80 gauge film is 0.8 mil thick. Higher gauge is thicker film with more puncture resistance and holding force.

What gauge stretch film should I use?

60 to 63 gauge for uniform cartons under 1,500 lb by hand, 80 gauge for mixed or heavier loads, 90 to 120 gauge blown film for sharp or irregular loads. Machine wrappers usually run 63 to 80 gauge at 200 to 250 percent pre-stretch.

Is 80 gauge thicker than 60 gauge?

Yes. 80 gauge is 0.8 mil (20.3 microns) and 60 gauge is 0.6 mil (15.2 microns), a third thicker. 80 gauge holds roughly 2,400 lb loads against 1,500 lb for 60 gauge on a uniform pallet.

How much stretch film does one pallet use?

A 48 x 40 pallet loaded 60 inches high takes about 147 ft of 18 inch film at no stretch, 59 ft at 150 percent and 42 ft at 250 percent, assuming 3 bottom wraps, 2 top wraps and 50 percent overlap.
