Abstract
The invention provides a process for the preparation of a seed support that comprises a biodegradable polymer film having a plurality of seeds at least partially embedded therein, the process comprising the steps of
- (a) providing a hydrophobic release liner (18);(b) applying a coating of an aqueous dispersion or solution comprising a biodegradable polymer on the hydrophobic release liner (18), wherein the dispersion or solution has a viscosity of from 2000 to 16000 mPa·s and a water content of from 58% to 90% by weight of the coating;(c) depositing a plurality of seeds onto the coating so that the seeds become at least partially embedded in the coating;(d) drying the coating to give a final water content of 1.5% to 15% by weight and thereby form the biodegradable polymer film; and(e) detaching the hydrophobic release liner from the biodegradable polymer film to give the seed support.
