Shrink Tunnel Machine 4525H

Get the choice, quality & service you want with professionals.

The shrink tunnel 4525H supplies heated air to an enclosed chamber with the purpose of shrinking a polymeric film around a package. This packaging method protects products from moisture, dust, and grazing, all while improving the product's overall appearance for added value and display. It also provides the advantage of nicely compacting a group of bundled articles together to reduce storage and packaging space, as well as to improve the overall packaging quality of a product. This automatic continuous shrink packaging equipment includes an electronically controlled conveyor to adjust until the perfect sealing effect is obtained.
