The right greenhouse plastic thickness depends on the greenhouse structure, local climate, wind conditions, expected service life and the performance of the film itself.

For many commercial greenhouse projects, common film thicknesses include:

120 micron, 150 micron, 180 micron and 200 micron.

In general:

• 120–150 micron is often used for standard or moderate greenhouse applications.

• 150–180 micron is common for commercial greenhouse projects.

• 180–200 micron is often considered for more demanding conditions, larger structures or projects requiring greater mechanical strength.

However, thicker film is not automatically better.

A high-quality 150 micron greenhouse film with proper UV stabilization and multi-layer construction may perform better than a poorly formulated 200 micron film.

The correct choice should therefore consider:

Thickness + UV Stabilization + Film Structure + Climate + Greenhouse Design + Required Lifetime

Quick Greenhouse Film Thickness Guide

These are general guidelines only.

The final thickness should be selected according to the actual greenhouse project.

What Does Greenhouse Film Thickness Mean?

Greenhouse plastic thickness is usually measured in microns, also written as:

μm

For example:

• 100 micron = 0.10 mm

• 120 micron = 0.12 mm

• 150 micron = 0.15 mm

• 180 micron = 0.18 mm

• 200 micron = 0.20 mm

The thicker the film, the more material is used per square meter.

This usually affects:

• Film weight

• Mechanical strength

• Cost

• Roll weight

• Installation

• Transportation cost

But thickness alone does not determine greenhouse film quality.

Is Thicker Greenhouse Plastic Better?

Not always.

A thicker film may provide:

• More material

• Greater puncture resistance

• Higher mechanical strength

• Better tolerance of handling and wind stress

But greenhouse film performance also depends on:

• Resin quality

• Layer structure

• Tensile strength

• Tear resistance

• UV stabilization

• Film formulation

• Installation quality

This means:

A thicker film can be stronger, but a thicker film is not automatically a better greenhouse film.

A professional buyer should compare the complete technical specification.

What Thickness Is Best for a Commercial Greenhouse?

For many commercial greenhouse projects, 150–200 micron is a common range.

However, the right choice depends on the project.

150 Micron

Often suitable for:

• Standard commercial greenhouses

• Moderate climates

• Well-protected structures

• Projects balancing cost and durability

180 Micron

Often suitable for:

• Larger greenhouse structures

• More demanding wind conditions

• Buyers wanting additional mechanical strength

• Multi-year greenhouse applications

200 Micron

Often considered for:

• Heavy-duty commercial projects

• Strong wind exposure

• Large multi-span greenhouses

• Higher-value greenhouse installations

• Buyers prioritizing mechanical robustness

The greenhouse frame and fixing system are just as important as film thickness.

120 Micron Greenhouse Film

A 120 micron film may be appropriate for lighter greenhouse applications.

Typical advantages include:

• Lower weight

• Lower material cost

• Easier handling

• Good flexibility

However, it may not be the best option for very demanding conditions.

Consider 120 micron when:

• Wind exposure is moderate

• The greenhouse structure is protected

• Long-term heavy-duty use is not required

• The project is cost-sensitive

150 Micron Greenhouse Film

150 micron is one of the most common thicknesses for commercial greenhouse film.

It offers a good balance between:

• Cost

• Weight

• Mechanical performance

• Ease of installation

• Commercial greenhouse suitability

It can be produced with functions such as:

• UV stabilization

• Anti-fog

• Anti-drip

• IR

• EVA

• Light diffusion

For many greenhouse projects, 150 micron can provide excellent cost-performance.

180 Micron Greenhouse Film

180 micron film sits between 150 and 200 micron.

It may be a useful choice when the buyer wants:

• More material than 150 micron

• Less weight than 200 micron

• Higher mechanical strength

• A balance between cost and durability

This makes 180 micron a practical option for commercial projects that do not necessarily require the full weight of 200 micron film.

200 Micron Greenhouse Film

200 micron film is commonly considered for demanding commercial greenhouse projects.

Compared with 150 micron film, 200 micron contains approximately:

33% more material per square meter

assuming similar density and formulation.

This can provide:

• Higher film weight

• Greater mechanical strength

• More resistance to stress

• A more heavy-duty specification

However, 200 micron film also means:

• Higher material cost

• Heavier rolls

• More transportation weight

• More difficult handling in some installations

So buyers should consider total project requirements rather than simply choosing the thickest film.

Which Thickness Is Best for Strong Wind?

In windy regions, thicker film may provide additional mechanical strength.

For example, 180 or 200 micron may be worth considering.

But wind resistance depends heavily on:

• Greenhouse frame strength

• Film fastening system

• Installation tension

• Greenhouse height

• Span size

• Wind direction

• Film tear strength

A poorly installed 200 micron film may still fail.

A properly installed 150 micron film on a strong greenhouse structure may perform very well.

So thickness should never be treated as the only wind-resistance factor.

Which Thickness Is Best for Hot Climates?

In hot climates, thickness is not usually the first priority.

More important factors can include:

• UV stabilization

• Light transmission

• Light diffusion

• Heat management

• Ventilation

• Film optical properties

For example, a 150 micron high-diffusion PO film may perform better for crop light management than a clear 200 micron film in a strong-sunlight region.

For hot climates, buyers should focus on:

UV + Diffusion + Film Structure + Thickness

together.

Which Thickness Is Best for Cold Climates?

In cold climates, film thickness can contribute to durability, but thermal properties are also critical.

Important functions may include:

• IR

• EVA

• Anti-fog

• Anti-drip

• Good light transmission

A 200 micron film without thermal functionality is not automatically better than a 150 micron film with proper IR and EVA design.

For cold regions, consider:

Thickness + IR + EVA + AF

rather than thickness alone.

Which Thickness Is Best for Tropical Climates?

In tropical and humid regions, common priorities include:

• UV stabilization

• Anti-fog

• Anti-drip

• Light transmission

• Humidity management

Both 150 and 200 micron can be suitable.

The final choice should depend on:

• Wind

• Greenhouse structure

• Expected lifetime

• Local solar radiation

• Budget

Greenhouse Film Thickness by Climate

Again, these are general guidelines, not universal rules.

Greenhouse Film Thickness by Greenhouse Type

Small Tunnel Greenhouse

Possible range:

100–150 micron

depending on structure and lifetime.

Commercial Single-Span Greenhouse

Possible range:

120–180 micron

depending on climate and frame strength.

Multi-Span Commercial Greenhouse

Possible range:

150–200 micron

especially where long-term performance and mechanical durability are important.

Large Professional Greenhouse

Often:

180–200 micron

may be worth evaluating.

However, advanced film formulation is still more important than thickness alone.

Does Film Thickness Affect Service Life?

Yes, but only partially.

A thicker film contains more material and may resist mechanical damage better.

However, service life is strongly affected by UV degradation.

The actual lifespan depends on:

• UV stabilization

• Local solar radiation

• Temperature

• Chemicals

• Film formulation

• Installation

• Film contact with greenhouse structure

So:

200 micron does not automatically mean 5-year life.

A 150 micron film can also be designed for multi-year use if the correct UV stabilization system is used.

Does Film Thickness Affect Light Transmission?

Thickness can influence optical performance, but many other factors matter too.

These include:

• Resin

• Layer structure

• Diffusion additives

• Film clarity

• EVA

• Aging

• Dust

• Surface treatment

Therefore, buyers should request actual data for:

• Light transmission

• Diffusion

• Haze

• IR performance

instead of guessing based on thickness.

Does Film Thickness Affect Price?

Yes.

A thicker film requires more raw material per square meter.

For example:

200 micron compared with 150 micron uses approximately:

200 ÷ 150 = 1.33

or around 33% more material per square meter.

This generally increases:

• Film cost

• Roll weight

• Transport weight

However, buyers should calculate cost per square meter and total greenhouse coverage, not only price per kilogram.

Greenhouse Film Thickness and Container Loading

Film thickness also affects how much greenhouse area can be covered per ton.

Thinner film generally covers more square meters per kilogram.

Thicker film covers fewer square meters per kilogram.

For distributors, this affects:

• Container capacity

• Inventory

• Freight cost

• Cost per square meter

• Resale pricing

This is why thickness is both a technical and commercial decision.

Does Crop Type Determine Film Thickness?

Not directly.

Crop type has a bigger effect on optical and climate requirements.

For example:

Tomato

May require:

• Good light transmission

• Suitable diffusion

• Anti-fog

• IR depending on climate

Cucumber

May benefit from:

• Diffusion

• Anti-fog

• Humidity management

Pepper

May require:

• UV stability

• Light diffusion in strong sunlight

Flowers

May require more precise control of:

• Light

• Diffusion

• Temperature

• Condensation

The crop helps determine the film functions, while structure and climate help determine thickness.

150 Micron vs 200 Micron: Which Should I Choose?

Choose 150 micron if:

• You want a balance between cost and durability

• The greenhouse structure is well protected

• Wind conditions are moderate

• Lower roll weight is preferred

Choose 200 micron if:

• The greenhouse is larger

• Wind exposure is more demanding

• Greater mechanical robustness is preferred

• The project is heavy-duty

• Higher material cost is acceptable

Neither is automatically better.

The right choice depends on the entire project.

Common Mistakes When Choosing Greenhouse Film Thickness

Mistake 1: Choosing the Thickest Film Automatically

Thicker film is not always the best value.

Mistake 2: Choosing Only by Price

Very thin low-cost film may increase replacement frequency.

Mistake 3: Ignoring UV Stabilization

Thickness cannot replace UV protection.

Mistake 4: Ignoring Greenhouse Structure

A weak frame can damage even a thick film.

Mistake 5: Ignoring Film Functions

IR, AF, EVA and diffusion may matter more than an extra 20–50 microns.

How to Choose the Right Thickness in 6 Steps

Step 1 — Check Local Climate

Consider:

• Wind

• UV

• Temperature

• Humidity

Step 2 — Check Greenhouse Structure

Consider:

• Tunnel

• Single-span

• Multi-span

• Large commercial structure

Step 3 — Decide Expected Lifetime

Determine whether the film is intended for:

• Seasonal use

• 1–2 years

• 3 years

• Longer-term use

Step 4 — Select a Thickness Range

For example:

120 / 150 / 180 / 200 micron

Step 5 — Select Required Functions

Choose:

UV / IR / AF / EVA / Diffusion / Anti-Drip

Step 6 — Confirm With the Manufacturer

Provide the full project information before placing an order.

Example 1: Standard Commercial Greenhouse

Crop: Tomato
Climate: Moderate
Structure: Commercial greenhouse
Wind: Moderate
Lifetime: 2–3 years

A 150 micron greenhouse film may provide a suitable balance of cost and performance.

Example 2: High-Wind Commercial Greenhouse

Crop: Vegetable
Structure: Large greenhouse
Wind: Strong
Lifetime: Multi-year

A 180 or 200 micron film may be worth considering together with proper fastening and UV stabilization.

Example 3: Hot Desert Greenhouse

Climate: High UV and strong sunlight
Crop: Pepper
Main concern: Solar radiation

Instead of only choosing thicker film, the buyer should also consider:

High UV stabilization + Light Diffusion + Suitable Thickness

A 150 or 200 micron PO film could both be suitable depending on the greenhouse design.
