How Do You Shrink PVC Film?

Feb. 10, 2023

PVC (polyvinyl chloride) film is a popular material used in various industries, including packaging, electrical insulation, and printing. PVC shrink film is known for its flexibility, durability, and water resistance, making it a versatile material for a variety of applications. However, PVC shrink film is often supplied in rolls, which can be difficult to handle and store. Shrink wrapping is a common way to reduce the size of PVC shrink film rolls, making them easier to handle, store, and transport. In this article, we will discuss how to shrink PVC film using a heat gun.


Choose the Right Heat Gun

A heat gun is an essential tool for shrinking PVC film. Heat guns are available in different sizes and wattages. For shrinking PVC film, you need a heat gun with a wattage of at least 1500W. This will provide enough heat to shrink the PVC shrink film quickly and effectively.


Prepare the Work Area

Before you start shrinking the PVC shrink film, you need to prepare the work area. Make sure you have a flat and clean surface to work on. It is also essential to ensure that the area is well-ventilated to prevent the buildup of fumes from the PVC shrink film.

Unroll the PVC shrink Film

Once you have prepared the work area, unroll the PVC shrink film to the desired length. It is essential to make sure that the PVC shrink film is free from any wrinkles or creases before you begin to shrink it.


Hold the Heat Gun at the Right Angle

Hold the heat gun at a 45-degree angle to the PVC shrink film, and keep it moving in a back-and-forth motion. This will ensure that the heat is evenly distributed across the PVC shrink film. Do not hold the heat gun too close to the PVC shrink film, as this can cause the film to melt or burn.


Apply Heat to the PVC Film

Start at one end of the PVC shrink film and apply heat to the surface using the heat gun. Move the heat gun back and forth across the PVC shrink film, making sure to cover the entire surface evenly. As the PVC shrink film heats up, it will start to shrink.

Use a Squeegee to Smooth the Surface

As the PVC film shrinks, use a squeegee to smooth the surface. This will ensure that the film remains flat and does not form any wrinkles or creases. Start at one end of the PVC shrink film and work your way to the other end, using the squeegee to smooth out any bumps or bubbles.


Repeat the Process as Needed

If the PVC shrink film has not shrunk to the desired size, repeat the process until it has shrunk to the desired size. However, be careful not to overheat the PVC shrink film, as this can cause it to shrink too much or even melt.


Cut the PVC Film to Size

Once the PVC shrink film has shrunk to the desired size, cut it to the desired length using a sharp knife or scissors. Make sure to cut the PVC shrink film evenly to ensure that it is the right size for your needs.

Store the PVC Film

After you have shrunk and cut the PVC shrink film, it is ready for storage. Store the PVC shrink film in a cool, dry place away from direct sunlight and moisture. This will help to preserve the quality of the film and prevent it from becoming brittle over time.


In conclusion, shrinking PVC shrink film using a heat gun is a straightforward process that can help you to reduce the size of your PVC shrink film rolls. However, it is essential to take the necessary precautions to ensure that you do not overheat or damage the PVC shrink film. By following these steps, you can shrink PVC film quickly and effectively, making it easier to handle, store, and transport.
