Shrink Tunnels

Shrink Tunnels: Equipment Overview

Technogen Enterprise manufactures and supplies Shrink Tunnels for suitable film-wrapping and shrink-sleeve packaging operations. The range includes Automatic Electric Heat Shrink Tunnel Machines and Automatic Steam Heat Shrink Tunnel Machines. Both use controlled heating to contract appropriate packaging films, but the heat-transfer method and utility requirements differ substantially.

Electric tunnels typically use heated air within an enclosed chamber, whereas steam tunnels apply a controlled steam environment suited to particular sleeve materials and pack shapes. Film shrink response depends on material formulation, sleeve or film dimensions, conveyor speed and product heat tolerance. The available tunnel opening must accommodate the pack with appropriate clearance, and process trials help identify acceptable finish conditions.

As a manufacturer, supplier and exporter in Ahmedabad, Technogen Enterprise requests product dimensions, film type, desired shrink appearance, line speed and electrical or steam utility information. We can then evaluate the relevant tunnel type for the intended packaging stage.
