Abstract [en]

Greaseproof papers with different air permeances were coated with chitosan, both on a bench scale and on a pilot scale to study the conditions necessary to obtain a packaging material with good oxygen barrier and high grease resistance. The results showed that an oxygen transmission rate in the same range as that of poly(ethylene terephatalate) was obtained at coat weights exceeding 5 g/m². High grease resistance values were also obtained at this coat weight while water resistance was slightly deteriorated due to the hygroscopic character of chitosan. However, that coat weight could only be achieved on papers coated on a bench scale. On a pilot scale, the maximum coat weight was 0.2 g/m² because the solids content of the coating solution used was limited to 1.0 wt%. The coating on a pilot scale was performed using the metered size press technique. To increase the coat weight, the solids content of the solution must be increased considerably. A coating technique which yields higher coat weights might also be necessary.
