GUARANTY
*Kit test back: the board is treated with grease resistance on the reverse. The grease resistance is measured by means of the standard kit test (observation of the grease on the surface of the reverse). The fatty product packed will not stain the reverse and the fat will not penetrate the board.
- All our grades can be glued with water based emulsion or Hotmelt glues but we recommend that trials are carried out.
- The material is not guaranteed for blister packaging, lamination and reverse printing.
- The board is guaranteed for 12 months in terms of its published specification.
- The mill specification is based upon 95% of the measured values being in tolerance.
