A shrink-sleeve tunnel offers 360-degree product coverage for all sorts of vessels like cans, bottles of all shapes and sizes, even items that require a tamper-evident seal. Shrink-sleeve tunnels maintain stable temperatures while shrinking packaging and labels as they are conveyed at variable rates of speed through the steam during the process.
At Electro-Steam, we have decades of experience crafting powerful steam generators for shrink tunnels. Our products can power your steam tunnel for an even and accurate label application.
How Shrink Tunnels Work
Shrink tunnels use a conveyor and heat to adhere packaging material to various products. The conveyor belt moves items through the shrink tunnel, where recirculating steam evenly heats the packaging. The conveyor speed can be adjusted to accommodate products and materials that require varied heat and moisture exposure.
The finished products feature securely fitting packaging with precise labeling and graphics.
How Steam Generators Provide Heat for Shrink Tunnels
Steam tunnels operate at a lower temperature than tunnels with infrared or recirculating heat. Steam-powered generators have high-pressure chambers filled with water that are heated to make steam. The steam moves through insulated steam lines where it is dispersed evenly into the stainless steel tunnel system, surrounding the product as it moves through.
Electro-Steam’s generators can power full-sleeve applications, using steam for shrink tunnels to uniformly heat packaging materials. This is ideal for producing high-quality, distortion-free graphics. Our generators are ASME, UL and cUL compliant to ensure safe and reliable performance.
Why Use Steam Generators in Shrink Sleeve Steam Tunnels
Steam generators offer many performance advantages that complement shrink-sleeve packaging processes:
- More Energy-Efficient: Steam tunnels for shrink sleeves require less energy than traditional heat tunnels and work faster.
- Even Heat Distribution: Evenly applied heat ensures all areas of the label shrink at the same rate, for more secure application.
- Superior Label Appearance: Steam shrink tunnels can achieve crisp, easily legible text and graphics with no deformities.
