A Buyer's Guide to 80 Gauge Stretch Wrap and Film Thickness

Key Takeaways

• An 80 gauge stretch wrap measures 0.80 mil or 20.32 microns, but some commercial charts round this to 20 microns.

• Gauge converts to microns by multiplying by 0.254, and microns convert back to gauge by dividing by 0.254.

• A gauge figure describes film thickness only and does not set a safe weight limit for a pallet.

• Load shape, sharp edges, containment force and pre-stretch level shape wrapping performance alongside film thickness.

• Comparing cost per securely wrapped pallet gives a clearer picture than roll price when choosing machine pallet wrap.

80 gauge stretch wrap measures 20.32 microns, or 0.80 mil (0.0008 inch), and some commercial charts round it to 20 microns. Supplier listings commonly rate 80 gauge film for pallet loads of roughly 2,200 to 2,500 lb. A damaged pallet is often blamed on film thickness. In reality, the wrong wrapping pattern, insufficient containment force or incorrect pre-stretch settings cause many load failures even when 80 gauge stretch wrap is used. Understanding what the gauge number actually means is the first step toward choosing the right film and reducing wrapping costs.

When a pallet arrives with a crushed corner or a shifted top tier, many teams add wraps or switch to a heavier roll. A higher gauge only adds thickness, though. Resin formulation, load shape and your wrapper's pre-stretch setting decide how well the film holds the pallet.

What stretch wrap gauge measures

Stretch wrap gauge is a thickness measurement. One hundred gauge equals 1 mil, and 1 mil is one thousandth of an inch, which converts to exactly 25.4 microns. That puts 80 gauge at 0.80 mil.

Gauge is common on North American roll labels, while microns are the metric unit used on many international datasheets, including ours.

Thickness indicates how much polymer is in each meter of film. Performance on the load is a separate question. Two films at the same gauge can stretch, cling and resist puncture differently, since resin formulation, the manufacturing process and the pre-stretch level all shape how the film behaves.

Rolls sold as an "equivalent" to a heavier gauge may measure thinner than the label suggests. Check the true micron thickness on the datasheet before comparing prices.

Stretch wrap gauge chart and micron conversion

Use this stretch wrap gauge chart to convert between the three units. It shows film thickness only and does not indicate the weight a pallet can safely carry.

For most warehouse operations, 70 to 90 gauge films represent the range commonly used for machine pallet wrapping. While 80 gauge stretch wrap remains a widely specified standard, the final choice depends on containment force requirements and machine performance.

Both conversions rely on the same factor of 0.254:

• Gauge to microns: Multiply the gauge figure by 0.254. An 80 gauge works out to 80 × 0.254 = 20.32 microns of film.

• Microns to gauge: Divide the micron figure by 0.254. A 23-micron film from a metric datasheet comes to roughly 90.6 gauge.

Some commercial charts round 80 gauge to 20 microns. When you compare stretch wrap thickness across suppliers, ask for the nominal micron value and its tolerance, and write both into your purchase specification. ASTM D4649, the standard guide for stretch film use, is intended to help buyers and sellers set those specifications.

Is 80 gauge stretch wrap strong enough for a heavy pallet?

It can be, provided the decision rests on more than pallet weight. Supplier listings commonly rate 80 gauge film for loads of roughly 2,200 to 2,500 lb (about 1,000 to 1,130 kg). Treat that range as seller guidance and a starting point for trials, since it assumes a stable, evenly stacked load and a sound wrapping pattern.

Load shape changes the picture quickly. Uniform, square cartons spread film tension across flat faces, while an equally heavy pallet of drums or parts with protruding edges concentrates it on corners where puncture and tearing begin. Containment force is the force stretched film exerts to hold a load together. 

A 2018 Virginia Tech study found that raising it improved unit load deflection (how much the loaded pallet bends) by as much as 81%, with the strongest effect on small packages and more flexible pallets. 

Film is also one part of load securing, alongside pallet condition, stacking pattern and the blocking, bracing or tiedowns required by US cargo securement rules.

Consider trialing a thicker or higher-performance film when you see these patterns:

• Irregular or sharp-edged loads: Corners, strapping buckles and protruding parts can puncture lighter film. A tougher grade or corner boards may reduce tears.

• Repeated film breaks: Breaks on the wrapper or during handling can point to a mismatch between film strength, pre-stretch setting and load profile.

• Poor retention after storage or transit: Loads that loosen or lean after days in the warehouse or a long export leg. Consider choosing something with a higher containment force.

Matching gauge to a machine wrapping setup

A gauge figure alone won't confirm that a machine film suits your wrapper, largely because of pre-stretch. This is how far the wrapper elongates the film before it reaches the load. At 200% pre-stretch, 1 meter of film from the roll covers 3 meters on the pallet, and the film on the load ends up much thinner than the gauge on the roll label.

Check these points together when matching film to equipment:

• Wrapper pre-stretch capability: Confirm whether your wrapper has a powered pre-stretch unit, as some higher grades are specified only for machines with pre-stretch capability.

• Recommended stretch range: Running beyond the datasheet range raises the risk of breaks, while running well below it uses more film per pallet.

• Load profile: Height, weight, surface texture and edge sharpness affect how much containment force the load needs and where film is likely to fail.

A thinner film made from a stronger, higher-performing resin can be comparable to a thicker one, as long as it suits your wrapper and the type of load. Compare cost per wrapped pallet rather than roll price, looking at film weight per pallet, break frequency, line stoppages and load condition on arrival.

Confirm the actual stretch wrap thickness and grade on each datasheet, then trial the film on loads that reflect your real product mix.

Machine-grade stretch film from MMP Corporation

MMP Corporation was established in Thailand in 1988. Our M Stretch machine roll film is made with metallocene polymer technology for durability and stretch. The range covers four grades with different thickness and pre-stretch profiles.

For buyers who specify in gauge, the 20-micron General Purpose film sits closest to 80 gauge, and the 23-micron option comes in just above 90 gauge. Our production facilities use MEASUREX film thickness gauge control to maintain consistent quality standards. Every machine film version is made to order, and we accept OEM orders to your specifications.

Match your film to your loads and wrapper

An 80 gauge film measures 20.32 microns, but that number describes thickness only. The right choice comes from matching film grade, pre-stretch level and load shape to your wrapper, then confirming it with the datasheet and a trial on your own pallets.

MMP Corporation produces M Stretch® machine roll film in four performance grades, with gauge-controlled production and made-to-order specifications for warehousing and export operations. It is manufactured using the latest metallocene polymer technology to provide extra durability and stretchability while being compatible with all types of pallet-wrapping machines.

Frequently Asked Questions About 80 Gauge Stretch Wrap (FAQs)

Q: What does gauge mean on stretch wrap?

A: Gauge is a unit of film thickness, where 100 gauge equals 1 mil (one thousandth of an inch) or 25.4 microns. A higher gauge number means thicker film, but it does not on its own indicate how much weight a wrapped pallet can hold.

Q: Is 80 gauge stretch wrap strong enough for a heavy pallet?

A: It can be, depending on the load. Supplier listings commonly rate 80 gauge for loads of roughly 2,200 to 2,500 lb, but irregular shapes, sharp edges, wrapper settings and transport conditions all affect whether it holds. Trial it on your own pallets before relying on it.

Q: How do I convert stretch film gauge to microns?

A: Multiply the gauge by 0.254 to get microns, and divide microns by 0.254 to get gauge. For example, 80 gauge equals 20.32 microns, and 23 microns equals about 90.6 gauge.

Q: What is the difference between 80 gauge and 90 gauge stretch wrap?

A: A 90 gauge film is 22.86 microns thick, about 2.5 microns more than an 80 gauge film at 20.32 microns. The extra thickness adds material per pallet, and whether it improves holding depends on the resin, pre-stretch level and load profile.

Q: Is thicker stretch wrap always better for pallets?

A: No. At the same wrap pattern, thicker film uses more material per pallet, and it does not automatically hold loads better. A well-matched higher-performance grade at a lower thickness can perform well on the right wrapper, and the best way to compare options is cost per securely wrapped pallet on trial loads.

Q: What stretch wrap thickness does MMP Corporation offer for machine wrapping?

A: MMP Corporation's M Stretch machine roll film runs from 12 to 30 microns depending on grade, across General Purpose, High Performance, Premium Performance and High Toughness options. The 20-micron General Purpose film is the closest match to 80 gauge, and all versions are made to order.
