TUN-4525H Shrink Tunnel: Advanced Packaging Excellence by PACKMACHINE, Bangalore for Seamless Wrapping and Sealing

Shrink Tunnel

The shrink tunnel TUN-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.
