How to use Shrink Wrapping Machine - Sleevelabeler

Using a shrink wrapping machine involves several steps, below is a general guide to using a shrink wrapping machine safely and efficiently:

1. Prepare the Machine

Read the Manual: Always refer to the manufacturer's instructions for your specific machine.

Inspect the Machine: Ensure the machine is clean and free of obstructions.

Set Up the Film Roll:

Load the shrink wrap film (typically made of polyolefin or PVC) onto the designated film holder.

Thread the film through the machine’s rollers or guides as per the manual.

2. Power On and Adjust Settings

Turn on the Machine: Plug it in and switch it on. Allow any heating elements to reach the desired temperature.

Set the Heat: Adjust the temperature settings for the shrink tunnel or heat gun based on the film type and product size.

Adjust Speed: If the machine has a conveyor, set the speed appropriate for your workflow.

3. Prepare the Product

Arrange the Product: Ensure the item to be wrapped is clean and dry.

Position the Product: Place it between the layers of shrink wrap film. For manual machines, this may involve manually folding the film around the product.

4. Sealing the Film

Use the Sealing Bar: For manual and semi-automatic machines, lower the sealing bar to cut and seal the film around the product.

Make sure the seal is complete and consistent to avoid gaps.

Automatic Machines: The machine will cut and seal the film automatically as the product moves through the system.

5. Shrink the Film 

Heat Application:

In a manual setup, use a heat gun and evenly apply heat over the film 

In semi-automatic and automatic machines, the product will pass through a shrink tunnel, where the heat shrinks the film.

Avoid Overheating: Keep the heat source moving to prevent burning or melting the film.

6. Inspect and Adjust

Check the Wrap: Ensure the film is tightly and uniformly shrunk without holes or wrinkles.

Make Adjustments: If necessary, tweak the heat or sealing settings for optimal results.

7. Cool Down and Shut Down

Cool the Machine: After completing your wrapping session, allow the machine to cool down before turning it off.

Clean Up: Remove any leftover film scraps and clean the machine.

Store Safely: Store the machine in a dry, safe location.

Safety Tips

Wear protective gloves when handling the machine.

Keep loose clothing and hair away from moving parts and heating elements.

Ensure adequate ventilation if using PVC shrink film, as it can release fumes.

By following these steps and adhering to the specific instructions for your shrink wrapping machine, you’ll ensure efficient and safe operation.
