  • the common disadvantage of the products made from the above materials is that they are essentially homogeneous substances that do not contain a layer that would make them suitable for permanent storage.
  • HU T-61.925 describes a starch matrix-containing laminated film with low permeability and the process for its production is known.
  • the film consists of two layers, the base layer of which contains starch and synthetic polymer, on which a hydrophobic second layer is applied.

  • the basis of the idea of the invention is the recognition that if the seedling is placed in a biodegrading container and the container is used for a double function, the disintegration of the container leads to the step-by-step fertilization with artificial fertilizer, so that the nutrients forming the artificial fertilizer only get the necessary amount Quantity, but certainly to the individual seedlings and thus you can achieve a cheaper solution than before.

  • the packaging material according to the invention has numerous advantages. It can be used for growing seedlings. It does not crumble to dust, it resists the earth and moisture from the outside. It is dimensionally stable and firm. The mechanical strength can be increased by means of grain straw. The disintegration time of the packaging material can be adjusted according to the requirements during production. The production process is simple and cheap. Baking in a microwave oven shortens the duration of production and reduces energy consumption by 20-50%.
