What Is a 1300 PE Double Winding Blown Film Machine?
Introduction
You run a plastic film factory. You need to produce high‑quality PE film for packaging, industrial use, or consumer goods. But you also need to maximize output and minimize downtime.
A standard film blowing machine uses a single winding shaft. When one roll finishes, the entire line stops while you unload and reload. That lost time adds up across a production shift.
The 1300 PE double winding blown film machine solves this problem. It uses two winding shafts that work alternately, allowing continuous production with no pauses for roll changes. One shaft winds while the operator unloads the finished roll from the other shaft.
In this guide, I explain what this machine is, how it works, what materials it handles. You will understand why the double winding design is a smart choice for high‑volume film production.
1.What Is a 1300 PE Double Winding Blown Film Machine?
A 1300 PE double winding blown film machine is a plastic film extrusion system that melts polyethylene (PE) resin pellets, blows them into a tubular bubble, and flattens the bubble into film. The “double winding” feature means the machine has two independent winding shafts. While one shaft winds a finished roll, the operator can remove the full roll from the other shaft and set up a new core—all without stopping the extrusion line.
2.How It Differs from a Single‑Winding Machine
| Feature | Single‑Winding Machine | Double‑Winding Machine |
| Roll change process | Line stops for each roll change | Continuous production, no line stop |
| Operator labor | Higher‑one operator required for roll change | Lower‑operator changes rolls while line runs |
| Output per shift | Lower (due to stoppages) | Higher (eliminates changeover downtime) |
| Equipment cost | Lower upfront | Higher upfront, faster payback through output |
3.Key Components of the 1300 PE Double Winding Blown Film Machine
3.1 Extruder Unit
The extruder is the heart of the machine. It melts the plastic resin pellets and pushes the molten material through the die head.
3.2 Die Head with Air Ring
The die head shapes the molten plastic into a tubular “bubble.” The air ring blows cooling air around the bubble to solidify the film at a controlled rate.
3.3 Collapsing Frame and Pinch Rollers
As the bubble rises, the collapsing frame flattens it into a double‑layer film. Pinch rollers then pull the flattened film downward at a controlled speed.
3.4 Double Winding Unit
This is the defining feature of the machine. The double winding unit consists of two independent winding shafts positioned one above the other.
3.5 Control System
Modern machines feature PLC‑based touchscreen controls for easy operation.
3.6 Embossing Roller (Optional)
Some applications require a textured film surface. An embossing roller creates a matte or patterned finish.

5.How Does the 1300 PE Double Winding Blown Film Machine Work?
The machine follows a continuous process from raw material to finished rolls.
Step 1: Material Feeding
The operator loads PE resin pellets (LDPE, LLDPE, or HDPE) into a hopper. Additives such as slip agents, antiblock, color masterbatch, or UV stabilizers can be blended at this stage.
Step 2: Melting and Extrusion
Pellets feed into the screw and barrel. Heaters along the barrel melt the resin at temperatures between 150°C and 220°C. The rotating screw pushes the molten material toward the die head.
Step 3: Bubble Formation
Melted plastic exits the die head as a tube. The internal air pressure expands the tube into a bubble. The air ring blows cooling air to solidify the film surface immediately.
Step 4: Bubble Collapsing
The bubble rises through the collapsing frame, which gradually flattens it into a double‑layer web of film. The film now travels downward through the tower.
Step 5: Winding
Flattened film passes through pinch rollers and guides to the double winding unit. The active winding shaft winds the film into a roll. When the preset roll diameter is reached, the machine automatically transfers the film to the second shaft. The operator then removes the finished roll from the first shaft and places a new core.
Step 6: Finished Roll Removal
The operator unloads the finished roll without stopping the extrusion line. The process repeats continuously.
6.What Materials Can the 1300 PE Double Winding Blown Film Machine Handle?
This machine is designed for polyolefin resins, with broad compatibility for various material blends.
| Material | Properties | Common Applications |
| LDPE | Soft, transparent, excellent flexibility | Shrink film, light‑duty bags, food packaging |
| LLDPE | High tensile strength, puncture resistance | Stretch film, heavy‑duty sacks, industrial liners |
| HDPE | Stiff, opaque, high strength | T‑shirt bags, garbage bags, grocery sacks |
| Recycled Material | Mixed‑grade, variable properties | Shopping bags, non‑critical packaging |
| Masterbatch Blends | Color, UV, slip, antiblock additives | Branded packaging, agricultural film |
7.Core Advantages of the 1300 PE Double Winding Design
- Continuous production : No line stoppage for roll changes. One shaft winds while you unload the other.
- Higher daily output : Eliminates downtime caused by roll changeovers, typically saving 30–60 minutes per shift.
- Reduced labor requirement : One operator can manage roll changes without stopping production.
- Consistent film quality : Extruder runs at steady state, avoiding start‑up and shut‑down variations.
- Faster return on investment : Increased output and reduced labor cost pay back the higher initial investment.
