For procurement managers, contractors, manufacturers, and project engineers, understanding LDPE sheet 500 micron price is important when planning material costs for agriculture, construction, water management, and industrial applications.

A 500 micron LDPE sheet is equivalent to 0.5 mm or approximately 20 mil. It is a flexible polyethylene sheet that provides moisture resistance, conformability, and a practical barrier solution for a range of applications.

However, there is no single fixed price for 500 micron LDPE sheet. The final quotation depends on material quality, thickness tolerance, additives, roll dimensions, order quantity, customization, packaging, transportation, and application requirements.

This guide explains what affects 500 micron LDPE sheet price, what specifications buyers should compare, and how to request a more accurate quotation from an LDPE sheet supplier.

Note: Prices for polyethylene sheets vary by resin market, specification, quantity, destination, and commercial terms. The figures in the original source are therefore not treated as universal market prices. For a project quotation, buyers should request current supplier pricing based on the exact specification.

What Is a 500 Micron LDPE Sheet?

A 500 micron LDPE sheet is a flexible polyethylene sheet with a nominal thickness of 500 microns, or 0.5 mm.

LDPE, or Low-Density Polyethylene, is known for its flexibility and ability to conform to irregular surfaces. Depending on formulation and manufacturing process, LDPE sheets can be supplied for agricultural, construction, industrial, environmental, and other applications.

Common characteristics include:

• Flexible material structure
• Good moisture resistance
• Low water permeability
• Good conformability
• Lightweight compared with thicker liners
• Available in different colors and dimensions
• Can be customized for specific projects

The actual performance of an LDPE sheet depends on the resin, formulation, thickness, manufacturing process, and testing requirements.

For engineered containment projects, buyers should distinguish between a general-purpose LDPE sheet and a geomembrane manufactured to a specific engineering specification.

500 Micron LDPE Sheet Specifications

Thickness is only one part of the product specification.

When purchasing a 500 micron LDPE sheet, buyers should also evaluate the following properties.

The original source lists a range of tensile, tear, puncture, UV, thermal, and roll-dimension values, but those values should not be treated as universal specifications for every 500 micron LDPE sheet.

The correct approach is to compare the supplier’s current technical data sheet with the project specification.

500 Micron LDPE Sheet Weight

For polyethylene sheet, thickness can be used as a basic reference when estimating material weight, but the actual weight per square meter depends on the material density.

At 500 microns:

Thickness = 0.5 mm

For purchasing calculations, buyers should use the manufacturer’s declared density and actual product tolerance rather than relying on a single theoretical weight.

This becomes particularly important when calculating:

• Total order weight
• Container loading
• Freight cost
• Roll weight
• Handling requirements

What Determines LDPE Sheet 500 Micron Price?

The price of a 500 micron LDPE sheet is influenced by several factors.

1. Raw Material Quality

Polyethylene resin is one of the major cost components.

Suppliers may offer different formulations based on:

• Virgin resin
• Recycled content
• Resin grade
• Additives
• UV stabilizers
• Processing requirements

For demanding engineering applications, buyers should clearly specify whether virgin material is required and whether recycled content is acceptable.

For lower-risk temporary applications, different material specifications may be appropriate.

Therefore, comparing two prices without comparing their material formulations can be misleading.

2. Thickness and Thickness Tolerance

Although this article focuses on 500 micron LDPE sheet, suppliers may also manufacture 300, 500, 750, 1000 micron, and thicker sheets.

As thickness increases, material consumption generally increases, which affects the product cost.

A thicker sheet is not automatically the correct choice.

The required thickness should be determined by:

• Project loading
• Subgrade conditions
• Installation method
• Expected exposure
• Required mechanical properties
• Design specifications

3. Order Quantity

Order quantity can influence the quotation because production setup, packaging, and logistics costs are distributed differently between small and large orders.

When requesting a quotation, specify:

• Total square meters
• Number of rolls
• Roll dimensions
• Delivery destination
• Required delivery date

For larger projects, suppliers may also provide customized roll dimensions to reduce field seams and installation waste.

However, volume discounts vary by supplier and should be confirmed in the actual quotation rather than assumed.

4. Roll Width and Length

Roll dimensions have a direct influence on manufacturing, packaging, container loading, and installation.

A wider roll may reduce the number of field seams in some applications, but it may also affect transportation and handling.

For example, Tinhy’s current LLDPE geomembrane products are available in thicknesses from 0.5 mm to 3.0 mm, with roll widths of approximately 5.8–8 m and roll lengths of 50–150 m, depending on the product.

The best roll size should therefore be selected according to both manufacturing capability and site installation requirements.

5. Additives and Special Formulations

Standard LDPE and specialized LDPE sheets can have different formulations.

Depending on the application, buyers may require:

• UV stabilizers
• Color masterbatch
• Anti-block additives
• Slip additives
• Special weathering resistance
• Specific chemical resistance
• Custom formulation

Additional formulation requirements can affect the final quotation.

Outdoor agricultural or containment applications should be evaluated differently from temporary indoor packaging applications.

6. Fabrication and Seaming

The base material price is not always the same as the final project cost.

If the LDPE sheet needs fabrication, cutting, welding, or prefabrication, additional costs may apply.

Potential cost components include:

Sheet material + fabrication + packaging + transportation + installation

For containment projects, the seaming method should be confirmed before purchasing the material.

The supplier should also confirm whether the selected LDPE formulation is compatible with the intended welding equipment and process.

7. Transportation and Logistics

For international B2B orders, logistics can represent an important part of total landed cost.

The quotation may depend on:

• Factory location
• Port of loading
• Destination
• Incoterms
• Container type
• Roll dimensions
• Total shipment weight
• Freight market conditions

A supplier offering a lower ex-factory price may not necessarily have the lower delivered cost.

For this reason, buyers should compare quotations using the same commercial terms.

500 Micron LDPE Sheet Applications

500 micron LDPE sheets can be used in different industries depending on the product formulation and technical requirements.

Agriculture

LDPE sheets may be used for:

• Agricultural liners
• Moisture barriers
• Irrigation-related applications
• Temporary covers
• Soil and crop protection systems
• Greenhouse-related applications

For long-term outdoor use, UV resistance and environmental exposure should be considered.

Construction

Potential construction uses include:

• Moisture barriers
• Temporary protective sheets
• Foundation protection
• Construction covers
• Containment applications
• Selected vapor-control applications

The product should be selected according to the applicable building or project specification.

Water Management

LDPE and LLDPE geomembranes can be used for selected:

• Ponds
• Irrigation systems
• Water storage
• Canals
• Agricultural reservoirs
• Containment systems

For engineered water-containment projects, geomembranes manufactured to an appropriate specification may be preferable to general-purpose LDPE film.

Environmental and Industrial Applications

Depending on the formulation and project specification, polyethylene liners can also be considered for:

• Secondary containment
• Industrial protection
• Waste-related applications
• Mining-related containment
• Environmental protection systems

The chemical compatibility of the membrane should always be evaluated before use.

LDPE Sheet vs HDPE Geomembrane

Buyers sometimes use “LDPE sheet” and “geomembrane” interchangeably, but they are not always the same product category.

LLDPE is another polyethylene option that generally provides greater flexibility and elongation than HDPE.

Tinhy’s current LLDPE geomembrane range is specified from 0.5–3.0 mm and is offered in smooth and textured configurations.

For a demanding engineering project, the decision should therefore be based on the required material properties rather than the lowest price.

Does 500 Micron Mean 0.5 mm?

Yes.

The conversion is:

500 microns = 0.5 mm = approximately 20 mil

This terminology is useful when comparing quotations from suppliers in different markets.

When requesting a quotation, it is better to state both units:

Thickness: 500 micron / 0.5 mm

This reduces the possibility of misunderstanding.

How to Choose a 500 Micron LDPE Sheet Supplier

A reliable supplier should be able to provide more than a unit price.

Ask for:

1. Technical Data Sheet

Confirm thickness, dimensions, material type, mechanical properties, and testing methods.

2. Material Information

Ask whether the product uses virgin resin, recycled material, or a specific blend.

3. Quality Control

Check how thickness, appearance, dimensions, and mechanical properties are controlled during production.

4. Sample

For a new supplier, requesting a sample can help verify:

• Flexibility
• Thickness
• Surface quality
• Color
• Welding behavior
• General material consistency

5. Testing Documents

For engineering projects, request factory test reports or third-party test reports where required.

6. Production Capability

Confirm:

• Available thickness
• Maximum roll width
• Roll length
• Monthly capacity
• Lead time
• Packaging method

7. Export Experience

For international projects, also check:

• Container loading
• Export packaging
• Documentation
• Incoterms
• Destination port
• Previous export experience
