Applications
Greyboard for tubes and cones
paperboard stiff tubes / cores for reels
the tube (or the cone) is made of paper stripes spiral wrapped round a metallic mandrel and glued. The number and characteristics of the stripes depend on the thickness of the core required.
main physical properties for the final use:
- grammage: from 120 to 500 g/m2
- thickness
- colour
- paper moisture between 5 and 7%, on demand
- bulk (inverse of density)
- Smoothness (calender)
- Porosity
- Ashes
main mechanical properties for the final use:
- delamination : an instrument called Scott Tester is used to measure the strength of inter fiber bonds of the paper subject to a force attempting to divide it into two layers.
- burst strength: strength of a paper sheet when is subjected to a force perpendicular to the surface.
- Taber Stiffness: resistance to bending
- sizing (Cobb): absorbance level
1. stripes or reels width between 5 and 230 cm
2. internal core and external diameter to be agreed before purchase
3. stretch film , pallets, neutral adhesive tape to be requested before purchase
Extra / Projects
- 1. coloured tubes and cones
