Shrink Tunnel Machine: Selection, Performance Factors, and Maintenance Best Practices
The quality of a shrink wrapped product is determined at the final stage of the packaging process — inside the tunnel. A shrink tunnel machine applies the controlled heat that activates the film's thermal memory, contracting it tightly around the product to produce the finished package. Getting this stage right requires the correct equipment for the application, correctly set up for the film and product being run, and properly maintained to sustain consistent performance across the machine's working life.
