A shrink tunnel is an industrial machine that uses heat or steam via a conveyor system to tighten plastic film snugly around packaged goods. Key components include a motorized conveyor, heating chamber, and adjustable temperature controls.
How It Works
- Products are loosely wrapped in a plastic film, such as PVC, POF (polyolefin), or PET.
- Items move along a conveyor belt directly into the heated tunnel chamber.
- Controlled hot air or steam shrinks the film tightly against the product shape, creating a secure, tamper-evident seal.
