TZ1600-100 Food Grade High-Speed Coating Line
Coating line features:
TZ1600-100 is a food-grade high-speed coating line with full sealing dust-free workshop. The products of this coating line apply to can ends & tabs. The pretreament process is different with other coating lines to meet the requirement of food-grade product. Expanding shaft loading system and waste gas treatment system is always recommended.
Application: For coating food grade aluminium and tinplate coils using for beverage can ends & tabs, Food can front ends & tabs, Food can bottom ends, PP caps, Closures, Aerosol can ends & components, Capacitors, etc.
Advantage:Food grade, high speed coating line, continuous production with loopers
