Name: Shrink Tunnels
Brand: Continental Paper and Plastics

Question 1

What chamber size options are available for shrink tunnels?

Accepted Answer

Shrink tunnels are available with chamber widths ranging from 16 inches to 30 inches or more, heights from 8 inches to 19 inches, and lengths from 28 inches to 60 inches or longer, depending on the model. These size variations allow for compatibility with a wide range of product dimensions.

Question 2

How does the heat output vary between different shrink tunnel models?

Accepted Answer

The heat output for shrink tunnels ranges from 2,900 watts to over 8,800 watts, depending on the model. Higher heat output models are typically suited for larger products or thicker shrink films requiring more energy for proper application.

Question 3

What are the advantages of using a shrink tunnel compared to a heat gun?

Accepted Answer

Shrink tunnels provide consistent and controlled heat distribution through ducting to the top, bottom, and sides, ensuring uniform shrinkage. In contrast, heat guns require manual operation and are less efficient for high-volume packaging needs.

Question 4

What power requirements should be considered when selecting a shrink tunnel?

Accepted Answer

Shrink tunnels operate on power configurations ranging from 110V single-phase to 230V three-phase, depending on the size and model. It is important to ensure that the facility’s electrical system matches the power requirements of the selected model.

Question 5

How does conveyor speed affect shrink tunnel performance?

Accepted Answer

Shrink tunnels feature variable conveyor speeds ranging from 0-30 feet per minute to 0-120 feet per minute. Adjusting the speed allows for precise control over the exposure time, ensuring optimal shrinkage for different film types and product sizes.
