Medical Grade Cast Film Extrusion Line

These production lines produce medical- grade film with thicknesses from 0.1 to 0.5 mm, in widths suitable for surgical drapes, instrument packaging, and hygiene product components.
Real-world case – Surgical drape lining film
A Malaysian medical consumables manufacturer uses the JCF-600MD to produce 400 mm wide PE film (0.25 mm thick) for disposable surgical drapes. The line runs at 8 m/min with an output of 14 kg/h – well within its maximum capacity of 15 kg/h.
Other common applications
Sterile barrier packaging for syringes and catheters (JCF-400MD, 200 mm width)
Breathable base film for medical protective clothing (JCF-800MD, 600 mm width)
Wound dressing release film – low adhesion, uniform thickness film
Narrow widths (200–600 mm) are ideal for in-house medical bag-making lines, reducing scrap and logistics costs.

Precise thickness control
Through die gap and chill roll precision, the line maintains a tolerance of ±0.01 mm across the full width – critical for medical barrier performance.

Low speed, high stability extrusion
Maximum line speed = 10 m/min. Unlike ordinary lines chasing 50+ m/min, the lower speed allows longer cooling time, better crystallinity, and fewer pinholes – essential for sterilegrade film.

Compact footprint and fast product changeover
The die- to- nip distance is optimised for quick cleaning. One European customer switches between 0.15 mm and 0.4 mm film in under 40 minutes, including die cleaning.

Medical- grade material compatibility
Supports PE, PP, TPU and EVA – all with available medical certification compliance. No toxic additive leaching into the film.

High output per unit energy
Maximum capacities:

18–22% more energy efficient than many older model lines.

We integrate in-line and off-line testing to meet ISO 13485 and FDA requirements.

In-line (real-time)
Thickness gauge scanning – records full-width thickness profile every 100 ms.
Pinhole detector – detects defects >0.05 mm using highvoltage spark testing.
Edge trim control – ensures final width accuracy within ±1 mm.

Off-line (laboratory, per batch)
Tensile strength (ASTM D882) – MD/TD ratio kept below 1.2 for balanced tear strength.
Elmendorf tear – minimum 2.5 N for 0.2 mm film.
Water vapour transmission rate (WVTR) – essential for breathable films; certificate supplied with each roll.
Microbial barrier test – using Bacillus subtilis spores. Film produced by JCF-800MD achieves >99.97% pass rate.

Real-world example
A Thai customer produced 500 kg of 0.3 mm PP film on a JCF-600MD. Off-line testing showed zero pinholes in a 10,000 cm² sample and thickness variation <0.008 mm – passing its EU surgical drape specification on the first trial.

Q1: Can you stably produce 0.1 mm film at 10 m/min?
A: Yes, but the chill roll temperature must be precisely set. For 0.1 mm, we recommend starting at 8 m/min, confirming roll uniformity before increasing speed. Many customers produce 0.12 mm at full speed without issues.

Q2: How often does a medical film line need die cleaning?
A: For unpigmented medical film, every 40–60 running hours. If slip agents are used, reduce to 30 hours. The quick-release die clamp on JCF-MD models reduces cleaning time to 15 minutes.

Q3: What if the film width I need is not 200/400/600 mm?
A: Each model’s die width is 400, 600 or 800 mm respectively – but final slitting allows any width below the maximum. For example, the JCF-800MD can produce 450 mm or 550 mm by adjusting the slitter knives. We can also customise the die lip for an exact width.

Q4: Does the line support in-line slitting?
A: Yes, with an optional driven slitting station. For medical applications, we recommend off-line slitting in a cleanroom to avoid particle generation during winding.

Q5: How stable is thickness when changing materials (PE to TPU)?
A: Screw and die temperatures need adjustment. PE to TPU requires about 50 kg of purging compound. After that, thickness returns to specification within 5 minutes. We provide a material change checklist with every line.

Q6: What is the typical output loss at start-up?
A: For a JCF-600MD producing 0.2 mm film: start-up loss is about 3.5 kg (approx. 20 minutes of output). After optimisation, our users report total waste (including edge trim) below 5%.
