Cork Sheet in Bangladesh: Complete Guide by SA EPS Insulation & Packaging
Introduction
In Bangladesh, the term “cork sheet” is widely used in industries such as packaging, insulation, and manufacturing. However, in most local applications, what is referred to as a cork sheet is actually an EPS (Expanded Polystyrene) sheet. At SA EPS Insulation & Packaging, we manufacture high-quality EPS sheets that are commonly known in the market as cork sheets and are extensively used for both protective packaging and insulation purposes.
This blog provides a complete, practical understanding of cork sheets (EPS sheets), including their properties, applications, advantages, and why they are the preferred solution across industries in Bangladesh.
What is a Cork Sheet (EPS Sheet)?
A cork sheet (locally known) is actually an EPS sheet, made from expanded polystyrene beads that are moulded into lightweight, rigid panels. These sheets are engineered to provide:
- Shock absorption
- Thermal insulation
- Lightweight handling
- Cost-effective protection
While natural cork exists in Bangladesh’s industrial and commercial sectors, EPS sheets dominate the market due to affordability, availability, and versatility.
How EPS Cork Sheets Are Manufactured
At SA EPS Insulation & Packaging, we follow a controlled manufacturing process to ensure consistent quality:
1. Pre-Expansion
Polystyrene beads are expanded using steam, increasing their volume and creating a closed-cell structure.
2. Ageing & Stabilisation
The expanded beads are stored to stabilise pressure and improve strength.
3. Moulding
The beads are moulded into block shapes or specific sheet sizes using heat and pressure.
4. Cutting & Shaping
Blocks are cut into required thicknesses and customised shapes depending on packaging or insulation needs.
This process ensures uniform density, durability, and performance.
Key Features of EPS Cork Sheets
Lightweight Structure
EPS sheets are extremely light, making them easy to transport and handle.
Excellent Shock Absorption
The closed-cell foam structure absorbs impact, protecting fragile items during transportation.
Thermal Insulation
EPS provides effective insulation against heat and cold, making it suitable for temperature-sensitive products.
Moisture Resistance
EPS sheets resist water absorption, maintaining performance in humid environments.
Customizable Design
Sheets can be cut, moulded, or shaped into various forms depending on packaging requirements.
Cost-Effective
Compared to alternative materials, EPS cork sheets offer superior performance at a lower cost.
Common Applications of Cork Sheet (EPS) in Bangladesh

1. Industrial Packaging
EPS cork sheets are widely used for packaging:
- Electronics (TV, appliances, equipment)
- Glass and ceramic products
- Machinery parts
- Battery and electrical components
They provide protection against shocks, vibrations, and damage during transit.
2. Food & Agricultural Packaging
EPS sheets are used for packaging:
- Honey jars
- Jam and pickle containers
- Dairy products
- Fish and meat transportation
- Fruits and vegetables
Their insulation properties help maintain freshness and product quality.
3. Construction & Insulation
EPS cork sheets are used in:
- Wall insulation
- Roof insulation
- Cold storage systems
- Sandwich panel cores
They help reduce energy consumption and improve temperature control.
4. Cold Storage & Refrigeration
EPS sheets play a critical role in:
- Cold rooms
- Portable cold storage units
- Ice boxes
They help maintain temperature stability, which is essential for food and pharmaceutical storage.
5. Custom Protective Packaging
At SA EPS Insulation & Packaging, we manufacture custom EPS cork sheet designs for:
- Ceiling fan packaging
- Rice cooker packaging
- Iron and appliance packaging
- Mug and jar holders
- Battery protection boxes
These are designed according to product dimensions to ensure maximum safety.
Technical Specifications of EPS Cork Sheets
While specifications can vary based on requirements, typical ranges include:
- Density: 10–35 kg/m³
- Thickness: 10mm to 200mm
- Size: Customizable
- Thermal Conductivity: Low (excellent insulation)
- Compressive Strength: High for lightweight material
We customise density and thickness depending on whether the application is packaging or insulation.
Advantages of Using EPS Cork Sheets
1. Superior Protection
EPS absorbs shocks better than many traditional materials, reducing damage risk.
2. Energy Efficiency
Used in insulation, it significantly reduces cooling and heating costs.
3. Lightweight & Easy Handling
Reduces transportation costs and simplifies installation.
4. Versatility
Applicable across industries—packaging, construction, agriculture, and logistics.
5. Cost Savings
Lower production and transportation costs make it ideal for bulk use.
6. Custom Manufacturing
Products can be tailored exactly to your needs.
Cork Sheet vs Natural Cork: What’s the Difference?
| Feature | EPS Cork Sheet (Used Locally) | Natural Cork |
|---|---|---|
| Material | Expanded Polystyrene | Tree bark |
| Cost | Low | High |
| Availability | High in Bangladesh | Limited |
| Usage | Packaging, insulation | Specialty uses |
| Weight | Lightweight | Medium |
| Customization | Highly customizable | Limited |
For most industrial and commercial uses in Bangladesh, EPS cork sheet is the practical and preferred choice.
