Introduction to Flowpack Machines
2026-01-20
A Flowpack Machine, also known as a horizontal flow wrapper, is an automated packaging system widely used in the food, daily necessities, pharmaceutical, and industrial sectors. Known for its high speed, efficiency, strong sealing performance, and aesthetically pleasing package appearance, it has become a core component of modern packaging production lines.
I. What Is a Flowpack Machine?
A Flowpack Machine packages products by automatically feeding film, forming the film around the product, sealing, and cutting. The finished package typically has a pillow-shaped appearance, which is why it is often called a pillow-type packaging machine.
The machine uses a horizontal film-feeding design and continuous-motion wrapping, making it ideal for individual or multiple items with regular shapes.
II. Working Principle
*Automatic feeding: Products are continuously transported into the machine via a conveyor belt.
*Film forming: The film roll is unwound and shaped into a tube that wraps around the product through a forming device.
*Longitudinal sealing: The film is sealed along the length of the product using heat-seal or cold-seal technology.
*End sealing & cutting: A rotary or reciprocating sealing unit seals both ends of the package and cuts it into individual units.
*Finished product output: Completed packages are discharged neatly from the outlet.
III. Key Features of Flowpack Machines
1. Attractive Packaging
The sealing is firm, the bag shape is neat, and the overall appearance enhances product presentation.
2. Strong Versatility
Suitable for a wide range of products, such as:
*Food: biscuits, bread, candy, frozen foods
*Personal care: wipes, soaps, toothbrushes
*Industrial parts: hardware, plastic components, stationery
*Medical products: masks, blister packs, sterile items
3. Compatible With Various Film Materials
Including BOPP, CPP, PE, laminates, and more.
4. Highly Integrable With Automation Systems
Such as:
*Automatic feeding or counting systems
*Date coding/printing devices
*Metal detectors
*Automatic sorting or alignment units
IV. Types of Flowpack Machines
1. Standard Flow Wrappers
Designed for general-purpose, high-speed packaging.
2. Servo-Driven Flowpack Machines
Use servo motors for higher precision and stability.
3. Flow Wrappers for Boxed/Trayed Products
Ideal for items that require orderly packaging.
4. MAP (Modified Atmosphere Packaging) Flowpack Machines
Inject protective gases to extend the shelf life of fresh foods.
V. Conclusion
Flowpack machines offer unmatched speed, reliable sealing, strong adaptability, and ease of operation, making them essential in modern manufacturing. Whether used for food, healthcare products, daily necessities, or industrial components, they significantly improve packaging efficiency, product quality, and cost-effectiveness.
