Shrink Packing Machine with Heat Tunnel | PVC, POF & PE Film Bundling

About Shrink Packing Machine with Heat Tunnel | PVC, POF & PE Film Bundling

A shrink packing machine encloses a product or group of products in shrink film, seals it, then passes it through a heat tunnel so the film contracts tightly around the pack. The result is a stable, dust-proof, tamper-evident multipack with a clean presentation. It supports PVC, POF and PE films and is used in food, beverage, pharmaceutical, electronics and logistics for bundling and palletizing.

How to Choose

  • Film type: POF for food and clarity, PE for heavy-duty pallets, PVC for small items—each needs matched seal/tunnel settings
  • Automation level: manual wrapping, semi-automatic with separate tunnel, or fully automatic inline systems
  • Pack style: single-item wrap, bundle (cans/bottles/boxes), sleeve label, or full pallet shrink
  • Shrink tunnel control: temperature range, airflow direction and conveyor speed for even, wrinkle-free shrinkage
  • Throughput and product size: packs per minute and the maximum width/height the sealer and tunnel accept

FAQ

Q: How does a shrink wrapping machine work?
A: Film is applied around the product, sealed on one or more edges, then the pack travels through a heat tunnel where the film shrinks to conform tightly to its shape.

Q: Which shrink film should I choose?
A: POF is common for food and retail clarity, PE is stronger for heavy pallets and bundling, and PVC suits small items—selection depends on product and appearance.

Q: What is the difference between bundling and pallet shrink wrapping?
A: Bundlers group cans, bottles or boxes into multipacks, while pallet shrink wrappers use thick PE film to secure whole pallets for shipping.

Q: Is shrink wrapping tamper-evident?
A: Yes. The tight, continuous film layer provides dust protection and a tamper-evident outer seal for retail and transit.
