Top 10 Blown Film Machine Manufacturers in the World (2026 Guide)
Blown film machines are essential equipment in the flexible packaging industry. In this guide, we review the top 10 blown film machine manufacturers in the world and explain how film blowing technology supports the production of plastic films used in packaging, agriculture, and industrial applications.
Blown film extrusion is one of the most widely used processes for producing plastic films such as PE film, PP film, and multilayer packaging films. These films are later printed, laminated, and converted into packaging materials.
Many packaging production lines start with film production and continue with printing and converting equipment such as flexographic printing machines , laminating machines, and slitting machines .

How Blown Film Machines Work
A blown film machine produces plastic film by melting polymer resin and extruding it through a circular die. The molten plastic forms a tube that is inflated with air to create a thin film bubble, which is then cooled and flattened into rolls.
A key parameter in blown film extrusion is the Blow-Up Ratio , which refers to the ratio between the bubble diameter and the die diameter. This parameter significantly affects film thickness distribution, mechanical properties, and production stability.
Main Applications of Blown Film Machines
- Flexible packaging films
- Food packaging materials
- Agricultural films
- Shopping bags and plastic bags
- Industrial protective films
- Shrink films
After film production, the plastic rolls are typically processed through printing, lamination, and slitting operations before being converted into finished packaging products.
Types of Blown Film Machines
Modern blown film extrusion technology includes several machine configurations depending on the packaging requirements.
| Machine Type | Main Feature | Typical Application |
|---|---|---|
| Single Layer Blown Film Machine | Simple film structures | Shopping bags, basic packaging |
| ABA Blown Film Machine | Cost-efficient multilayer film | General packaging films |
| 3-Layer / 5-Layer Blown Film Line | Advanced barrier properties | Food packaging |
Why Blown Film Technology is Important in Packaging
Blown film extrusion allows manufacturers to produce lightweight yet strong plastic films with excellent barrier properties. These films are widely used in modern flexible packaging applications.
With the continued growth of e-commerce and global food packaging demand, advanced multilayer blown film lines are becoming increasingly important in packaging production.
