Choosing the correct stretch film thickness is one of the most important decisions when selecting pallet packaging materials. If the film is too thin, it may tear during transport. If it is too thick, you may be paying for more material than your application actually requires.
In this complete stretch film thickness guide, we will explain what stretch film gauge means, the common thickness ranges used in packaging, and how to choose the right pallet wrap thickness for your specific loads.
What Does Stretch Film Thickness Mean?
Stretch film thickness refers to how thick the plastic film is. It is usually measured in microns (µm) or gauge.
- Micron (µm) – The most common measurement globally.
- Gauge – Often used in the U.S. packaging market.
To help understand the conversion:
| Gauge | Microns | Typical Application |
|---|---|---|
| 50 gauge | 12 microns | Light loads |
| 60 gauge | 15 microns | Light to medium loads |
| 70 gauge | 18 microns | Standard pallets |
| 80 gauge | 20 микрон | Medium loads |
| 90 gauge | 23 microns | Heavy pallets |
| 100–120 gauge | 25–30 microns | Very heavy or irregular loads |
Many buyers search for a stretch film gauge chart because it helps them quickly determine which film thickness is suitable for their packaging requirements.
Common Stretch Film Thickness Ranges
Most stretch films used in logistics and warehousing fall within 12–35 microns.
1. Light-Duty Stretch Film (12–15 Microns)
This thin film is ideal for lightweight packaging.
Common uses include:
- Small cartons
- Light retail products
- Bundling small items
- Short-distance shipping
Преимущества:
- Lower cost per roll
- Easy to apply manually
- Suitable for light pallet stabilization
However, it may tear if used on heavier or irregular loads.
2. Medium-Duty Stretch Film (17–23 Microns)
This is the most commonly used stretch film thickness in warehouses and distribution centers.
Typical applications:
- Standard pallet loads
- Consumer goods
- Food packaging pallets
- Electronics shipments
Benefits include:
- Good balance of strength and flexibility
- Reliable load stability
- Compatible with both manual and machine wrapping
Many businesses consider this thickness the standard pallet wrap thickness for everyday logistics.
3. Heavy-Duty Stretch Film (25–35 Microns)
Heavy stretch film is designed for demanding applications.
Best suited for:
- Industrial equipment
- Construction materials
- Heavy machinery parts
- Irregular or sharp-edged pallets
Преимущества:
- Maximum puncture resistance
- Strong load containment
- Better protection during long-distance transport
Although thicker films cost more per roll, they often reduce product damage and load failure.
How to Choose the Right Stretch Film Thickness
Selecting the correct film depends on three main factors.
1. Pallet Weight
The weight of the pallet is the most important factor.
General guideline:
| Pallet Weight | Recommended Thickness |
|---|---|
| Under 400 kg | 12–15 microns |
| 400–800 kg | 17–20 microns |
| 800–1200 kg | 20–23 microns |
| Over 1200 kg | 23–35 microns |
If your loads are heavier, you should always use thicker film for better stability.
2. Load Shape and Stability
Not all pallets are perfectly shaped. Irregular loads often require stronger film.
Examples of challenging loads include:
- Sharp corners
- Uneven cartons
- Loose stacked products
In these cases, thicker stretch film improves puncture resistance and prevents tearing.
3. Transportation Distance
The longer the shipping distance, the stronger your pallet wrap should be.
For example:
- Local deliveries may only require 15–17 microns.
- Domestic transport often uses 20–23 microns.
- International shipping may require 23–30 microns for added security.
Cost vs Durability: Finding the Right Balance
Many companies assume thicker stretch film is always better. However, that is not always true.
Using film that is too thick can lead to:
- Higher packaging costs
- Excess plastic usage
- Reduced operational efficiency
Modern high-performance films allow companies to downgauge—using thinner film while maintaining strength.
Benefits of downgauging include:
- Lower material cost
- Reduced plastic waste
- Improved sustainability
For example, a high-quality 20 micron film can sometimes replace a 23 micron standard film if it has higher stretch capacity.
Stretch Film Thickness Chart
Here is a quick stretch film thickness guide to help you choose the right option:
| Thickness (Microns) | Gauge | Recommended Use |
|---|---|---|
| 12 µm | 50 gauge | Light cartons |
| 15 µm | 60 gauge | Light pallets |
| 18 µm | 70 gauge | Standard loads |
| 20 µm | 80 gauge | Medium pallets |
| 23 µm | 90 gauge | Heavy pallets |
| 25–30 µm | 100–120 gauge | Industrial loads |
| 35 µm | 140 gauge | Extremely heavy products |
This stretch film gauge chart is widely used by packaging buyers when selecting pallet wrapping materials.
Manual vs Machine Stretch Film Thickness
Another factor to consider is whether the film will be applied manually or by machine.
Typical thickness:
- 15–23 microns
Преимущества:
- Easy to handle
- Suitable for small warehouses
- Lower equipment investment
Typical thickness:
- 20–35 microns
Benefits:
- Higher stretch ratios
- Faster pallet wrapping
- Consistent film tension
Large logistics centers usually prefer machine stretch film for efficiency.
Final Thoughts
Choosing the correct stretch film thickness can significantly improve pallet stability, reduce packaging costs, and prevent product damage during transportation.
To summarize:
- 12–15 microns – Best for light loads
- 17–23 microns – Ideal for standard pallets
- 25–35 microns – Suitable for heavy industrial loads
Before purchasing stretch film, always consider pallet weight, load shape, and transport distance. Using the right thickness ensures both cost efficiency and reliable product protection.
Businesses that follow a proper стретч-пленка thickness guide can optimize their packaging operations while improving supply chain performance.
FAQs Stretch Film
What is the standard stretch film thickness?
The most common stretch film thickness used for pallet wrapping is 17–23 microns (70–90 gauge), which provides a good balance of strength and flexibility.
Is thicker stretch film always better?
Not necessarily. While thicker film provides more strength, modern high-performance films allow companies to use thinner film with similar durability, reducing packaging costs.
What thickness stretch film is best for heavy pallets?
Heavy pallets usually require 23–35 microns stretch film to ensure strong load containment and puncture resistance.
What is the difference between microns and gauge?
Microns measure the film thickness directly, while gauge is a unit commonly used in the U.S. packaging industry. For example, 80 gauge equals approximately 20 microns.
