JWELL Functional Packaging Coating Production Line
JWELL's functional packaging coating production line coats high-barrier films for retort pouches, ambient barrier food packaging, ready-to-eat snack packaging, anti-static electronic packaging and other oxygen-, light- and moisture-barrier structures that can replace traditional aluminum foil, on substrates 800–2700 mm wide at working speeds of up to 400 m/min depending on material and process.
Key Selling Points
- Barrier-Oriented Coating Set: Reverse gravure, anilox direct coating and multi-roll precision metering units cover about 90% of high-barrier film process routes.
- Micron Coating Uniformity: Wet coating thickness at micron level, with coating uniformity typically within 5% depending on the process.
- Energy-Efficient Drying: Drying tunnel engineered for high efficiency and energy saving.
- Closed-Loop Tension: Fully closed-loop tension control for stable material handling.
- High-Speed Capability: Working speed of up to 400 m/min depending on material and process.

Application Scenario
Typical applications include high-temperature retort pouch food packaging, ambient-temperature barrier food packaging, ready-to-eat puffed and oily food packaging, anti-static barrier packaging for electronics, and other structures that require oxygen, light and moisture barrier performance as alternatives to aluminum foil.
Product Description
This line targets converters of high-barrier packaging films. Coating units are chosen to match barrier coating chemistries and film structures, with double-station unwinding and dual-station rewinding for continuous high-speed runs.
Working speed of up to 400 m/min depends on the material and process. Contact JWELL with your substrate, barrier coating, width and target application for a configured proposal.
