Shrink Wrapping Machine
A shrink wrapping machine is a packaging machine used to wrap products or packages with a plastic film and then shrink the film tightly around the product using heat. This process creates a secure and tamper-evident packaging for various items. Shrink wrapping is commonly used in industries such as food packaging, beverage packaging, cosmetics, pharmaceuticals, and many others.
Features
- Film Roll Loading: The machine typically starts with a roll of shrink film. This film can be made of various materials, including polyethylene, polypropylene, or PVC.
- Product Placement: The products or items to be wrapped are placed on a conveyor belt or tray, and they pass through the machine.
- Film Unwinding: As the product moves forward, the shrink wrap machine pulls the film from the roll and wraps it around the product.
- Cooling and Conveying: After the film has shrunk and conforms to the product’s shape, the product continues through the machine to a cooling section, where the film cools and solidifies.
- Cutting and Discharge: Finally, the wrapped product exits the machine, and any excess film is trimmed or cut away to create a clean, neat finish. The wrapped product is then discharged for further packaging or distribution.
