Cold laminating film and thermal laminating film are both used to protect printed materials, documents, photos, and other surfaces. Although they may look similar, they are two different types of laminating materials with different adhesive systems and application methods.
The main difference is:
Cold laminating film uses pressure-sensitive adhesive and does not require heat, while thermal laminating film uses heat-activated EVA adhesive and requires a laminating machine.
Cold laminating film is mainly suitable for DIY projects, advertising graphics, heat-sensitive materials, and temporary protection.
Thermal laminating film provides stronger bonding, edge sealing, waterproof protection, and long-term durability, making it suitable for documents, photos, frequently used materials, and professional applications.
Choosing the right laminating film depends on:
Protection requirements
Material type
Usage frequency
Available equipment
Application environment

Suitable applications
This guide explains the differences between cold laminating film and thermal laminating film to help you select the right product.
What Is Thermal Laminating Film?
Thermal laminating film is a protective film that uses a heat-activated adhesive system.
During the lamination process, the film passes through a thermal laminating machine. The heat activates the adhesive layer, allowing the film to bond with paper, printed materials, or other substrates.
The most common structure of thermal laminating film is:
PET Base Film + EVA Hot Melt Adhesive Layer
How Does Thermal Laminating Film Work?
The lamination process is based on heat activation:
The laminating machine heats the film.
The EVA adhesive layer melts.
The adhesive bonds with the material surface.
After cooling, the film forms a strong protective layer.
Because the adhesive requires heat to activate, thermal laminating film must be used with a laminating machine.
Thermal Laminating Film Material Structure
Huizhou YIDU Stationery Supplies Co., Ltd. has been developing laminating film technology for many years.
In 2009, YIDU developed a three-layer high adhesion laminating film structure: PET + PE + EVA
This structure combines different material advantages to improve the adhesion performance.
What Is Cold Laminating Film?
Cold laminating film is a self-adhesive protective film that does not require heat during application.
Unlike thermal laminating film, cold laminating film uses a pressure-sensitive adhesive (PSA) system.
The typical structure is:
Base Film + Pressure-Sensitive Adhesive + Release Paper or Release Film
The base film of cold laminating film including PVC, CPP or PET.
How Does Cold Laminating Film Work?
Cold laminating film bonds through pressure instead of heat.
The application process is simple:
Remove the release paper or release film.
Place the adhesive surface onto the material.
Apply pressure using hands or a scraper.
The cold film adheres to the surface.
Because no heating process is required, cold laminating film can be applied without a thermal laminating machine.
But the cold laminating roll film can be used with a lamintor with the 0 temperature setting.

Important Things to Know Before Laminating
Whether you choose cold laminating film or thermal laminating film, there are several important points to consider before lamination.
1. Lamination Is Usually an Irreversible Process
Lamination is designed to create a permanent bond between the film and the protected material.
Once the film has been applied:
The film is difficult to remove.
The original material may be damaged if separation is attempted.
Therefore, important original documents should be carefully considered before lamination.
Examples include:
Diplomas
Birth certificates
Original certificates
Legal documents
For valuable documents, users should confirm whether lamination is appropriate before processing.
2. Pay Attention When Punching Holes After Lamination
Some laminated products need to be hung or displayed.
When punching holes, it is recommended to place the hole within the sealed film edge area whenever possible.
Avoid damaging the paper area because this may:
Break the protective structure
Allow moisture to enter
Reduce outdoor durability
This is especially important for materials used in humid or outdoor environments.
3. Special Handling for Thermal Paper
Thermal paper is widely used in:
Supermarket receipts
Concert tickets
Movie tickets
Fax paper
Some transaction receipts
Thermal paper contains a heat-sensitive coating.
When exposed to heat:
The surface may turn dark.
Printed information may fade or disappear.
Therefore:
Thermal paper should not be laminated with thermal laminating film.
How to Protect Thermal Paper Correctly?
A common method is:
Apply cold laminating film to the surface.
Store the protected item in a card holder or protective sleeve.
This method can help slow down fading, but it cannot completely stop the natural aging process of thermal paper.
