7/9/11 Barrier Blown Film Extrusion Line

With its multi-layer barrier capabilities, the JBF Series is widely used for:
Fresh & Processed Meat Packaging – Vacuum or modified atmosphere packaging requiring high oxygen barrier to extend shelf life.
Cheese & Dairy Products – Prevents moisture loss and aroma escape while blocking external contaminants.
Medical & Pharmaceutical Films – Sterile barrier properties for surgical drapes, IV bags, and instrument packaging.
Industrial & Agricultural Laminates – Chemical resistance and mechanical strength for heavy-duty applications.
Snacks & Confectionery – Maintains crispness and flavor through excellent aroma barrier.
*Real-world case: After switching from a 5-layer to a JBF-1800 9-layer line, a European meat processor extended product shelf life from 21 to 35 days and reduced food waste by 18%.*

1. True Multi-Layer Flexibility (7/9/11 layers)
The modular die design allows you to run 7, 9, or even 11 layers on the same line. This means you can incorporate EVOH, PA, tie resins, and post-consumer recyclates exactly where needed – something not possible with fewer layers.

2. Wide Thickness & Width Range
Thickness: 0.03–0.2 mm – covering everything from high-speed laminating films to heavier stand-up pouch films.
Width: Max flat width 2100 mm – reduces downstream slitting waste and increases hourly output per line.

3. High Output with Moderate Power Consumption
The JBF-2300 achieves 400–500 kg/h with just 250–300 kW installed power – industry-leading specific energy consumption (approx. 0.6–0.75 kWh/kg).
This directly translates into lower electricity bills and a smaller carbon footprint.

4. Superior Barrier Performance
By distributing EVOH and PA in the inner layers, oxygen transmission rate can be as low as <1 cc/(m²·day) and water vapor transmission rate <2 g/(m²·day) at 0.05 mm thickness – ideal for long-term frozen or refrigerated storage.

5. Easy Layer Structure Changeover
The compact die and IBC (internal bubble cooling) allow fast purging and material switching. A typical 7layer → 9layer conversion takes less than 90 minutes.

We implement strict quality control procedures at every stage from raw materials to final winding.
In-Process Monitoring
Ultrasonic thickness gauge (online transverse scanning) – ensures thickness uniformity within ±5%.
Layer structure verification – uses a spectrometer to confirm each layer’s thickness and material composition.
IBC air temperature and frost line height – automatically adjusted by PLC to stabilize bubble geometry.
Laboratory Tests (per ASTM / ISO standards)

Finished Roll Inspection
Automatic optical inspection – detects gels, black specks, and fish eyes down to 0.1 mm.
Roll hardness and winding tension – checked to prevent telescoping or crushing.
*Case: A JBF-1600 line producing 9 – layer cheese film passed 48 hours of continuous OTR testing at 23°C/50% RH with readings consistently below 0.9 cc/(m²·day) – exceeding customer specifications by 30%.*

Q1: Can I run 7, 9, and 11 layers on the same die?
A: Yes. The JBF Series uses a modular stacked die. You can start with a 7 – layer configuration and later upgrade to 9 or 11 layers by adding additional distribution blocks and extruders. We offer retrofit kits.

Q2: What materials can be processed?
A: Typical materials include LDPE, LLDPE, HDPE, mLLDPE, EVA, EVOH (barrier layer up to 11 layers), PA6, tie resins (anhydride – modified), and up to 30% post – industrial recyclate in non – barrier layers.

Q3: How do you prevent thickness variation across 2100 mm width?
A: Our automatic profile control system uses 72 temperature zones on the die lip plus a rotating haul – off. The JBF – 2300 achieves thickness variation <±4% even at 2100 mm flat width.

Q4: What is the typical payback period?
A: At 300 kg/h output, running 16 hours/day, 300 days/year, producing barrier film with a €0.30/kg premium over commodity film – payback period is 12–18 months. Energy savings alone account for about 15% of the ROI.

Q5: How often should the screw or die be replaced?
A: With proper maintenance (regular purging, screw inspection every 2,000 hours), bimetallic screws last over 25,000 hours, and die rings (tungsten carbide coated) last over 15,000 hours. We keep spare parts in stock for fast replacement.

Q6: Do you provide training and commissioning services?
A: Yes. We include 14 days of on – site commissioning and operator training. Remote troubleshooting via VPN and 24/7 WhatsApp support are also available.

Q7: Can this line produce shrink film or stretch sleeve film?
A: Absolutely. By adjusting the blow – up ratio from 1.5:1 to 4:1 and modifying the cooling profile, the same line can produce:
Shrink film (BUR 2.5–3.5, fast quenching)
Stretch sleeve film (BUR 1.8–2.2, high MD tear strength)
Stand – up pouch film (with appropriate sealant layer)
