VCI Shrink film is a PE heat-shrink film made using LDPE as the base material. It has good toughness and flexibility and can be wrapped around the surface of metal products to form a protective layer.


When heated to a certain temperature, it naturally shrinks and tightly adheres to the metal surface, forming a tight protective layer that can effectively prevent air, moisture, and other corrosive substances from corroding and oxidizing the metal surface. At the same time, the addition of a new type of VCI vapor-phase rust inhibitor makes the heat-shrink film have excellent rust prevention performance, and it can be stored outdoors for 6-18 months after packaging.


It is mainly used in industries such as metal products, automotive parts, military equipment, large machinery, wind power, energy, and power equipment, especially for metal products and components that require long-term storage or transportation.



The fields in which VCI shrink film is suitable include:


1. Manufacturing

VCI shrink film is widely used in manufacturing industries such as automotive parts, machinery, tools, and metal products, and can effectively prevent oxidation and corrosion of metal products.

2. Military equipment

VCI Shrink film can effectively protect various military equipment and weapons from corrosion and damage in harsh battlefield environments.

3. Energy and power equipment

In the energy and power industry, VCI shrink film is often used to protect various power equipment and pipelines, such as transmission towers, transformers, oil pipelines, wind turbine hubs, etc., to enhance their service life.

4. Chemical industry

VCI shrink film is used as a packaging material in the chemical industry. As an efficient packaging material, it can alleviate defects and corrosion during the storage and transportation of chemicals.

5. Mining

VCI shrink film is used in the mining industry to protect various mining equipment, corridors, bridges, etc., and prevent rust and corrosion from damaging these equipment and facilities.


The advantages of rust-resistant heat-shrink film include:


1.High puncture resistance and tear strength.

2. Dust-proof, moisture-proof, damage-resistant, and high shrinkage rate.

3. Addition of a new type of VCI rust inhibitor, providing excellent rust-prevention performance.

4. Excellent adhesion, firm bonding at the packaging joints, ensuring overall stability, and reducing damage, collapse, and spillage during transportation.

5. Clean and tidy.

6. Environmentally friendly and safe during heat sealing.

7. Strong shrink memory function, tight retraction and fastening.

8. Reduces packaging costs and is easy to operate.



Here's an application case study for VCI shrink film:


With the increasing global demand for energy and growing environmental awareness, the application of renewable energy has been widely promoted. As a new type of environmentally friendly energy, wind energy plays an important role in this trend. Wind turbine assemblies serve as carriers for wind power generation, and their special working environment and high-density component requirements have doubled the demand for hubs. As one of the most important and complex components in wind turbine assemblies, the protection of hubs during the transportation process is crucial.


Customer requirement: Transport multiple sets of wind turbine hubs overseas, requiring 5 lifting operations. The packaging should facilitate convenient lifting, disassembly, and reassembly, while providing maintenance access and ensuring aesthetic and practical overall packaging.


To ensure that the wind turbine hubs are not damaged during transportation, they must be carefully and meticulously packaged. Rust-preventive heat shrink film serves as an ideal protective material, effectively preventing water vapor intrusion and providing protection against UV radiation, thereby extending the service life of wind turbine hubs.


We provided the customer with the highest quality packaging solution. This solution not only ensures lifting points, maintenance access, and product aesthetics but also offers convenience, resulting in a more perfect overall packaging of the hubs. The customer was highly satisfied.


Now, the shipping of wind turbine hubs has become safer.
