▋ Production Video

▋ Production Line

  • 4 production lines for polypropylene corrugated sheet,
  • 2 sets of three-color printing presses,
  • 3 ultrasonic welding machines,
  • 3 sets of pallet sealing side machine,
  • Multiple cutting equipment.

▋ Application

PACKAGING:

Polypropylene hollow fluted plastic boards can easily be die-cut, folded and glued (Corona treatment requested). Ultrasound or hot welding allow for making highly sophisticated boxes.

BUILDING:

  • Beam formwork
  • Fencing, construction panel
  • Floor, wall and window protection

PROTECTION:

  • Pallet upper/bottom protection sheets
  • Steel roll packing board
  • Roller packing board

SIGNS & DISPLAYS:

Polypropylene hollow sheets accentuate the photo rendering of your print with its mat silk touch and make your prints stand out from the rest.
