Automatic Shrink Wrapping with Tunnel Machine
The Automatic Shrink Wrapping Machine with Tunnel is a high-performance packaging solution engineered for bundling and wrapping bottles, cans, jars, cartons, or other containers in a tight, protective plastic film. After wrapping, the product bundle passes through a shrink tunnel, where heat causes the film to shrink tightly around the package, forming a secure, tamper-evident, and transport-friendly unit.

This system is widely used in beverages, pharmaceuticals, cosmetics, household products, food and dairy, and chemical industries, especially for secondary packaging of multiple units.

PET bottles, cans, and jars

Working Principle

Product Infeed: Bottles or containers move on a conveyor to the collation zone.
Grouping: The machine automatically arranges the products into the desired matrix (e.g., 6, 12, or 24 packs).
Film Wrapping: The film is pulled from a roll and wrapped around the group.
Sealing & Cutting: A hot knife sealing system seals the film and separates each wrapped pack.
Heat Shrinking: Wrapped packs move through a shrink tunnel where hot air shrinks the film tightly.
Cooling & Discharge: Packs cool down and exit the machine, ready for secondary packaging or dispatch.
