Punctual glueing process for support containing plant seeds

摘要

The procedure consists of applying an adhesive (4) to one layer (3) of biodegradable or water-degradable paper, film or substrate in small spots (4) less than 1 mm in diameter. The spots are spaced as far apart as possible commensurate with the quality of the layer material so that the two layers are held firmly together but with little statistical chance of any seed having its germination point covered with adhesive.
