  • the links 2 and 3 are fixed on the seeds 1, especially by gluing, and the packaging product according to the invention is in the form of a sheet 40.
  • the links are not necessarily distributed in two layers. So the popcorn seeds can be attached to a single layer of wire at least partially intertwined. However, the distribution of links in two layers provides a more resistant packaging product.
  • the angle that form between them the threads of the two layers is not necessarily equal to 90 °. It is enough that this angle is not bad.
  • the links can be made of assembled or woven fibers.
  • the links of two adjacent layers can also be partially fixed together.

  • the bonding of the seeds on these strips is then obtained by moistening these strips on the glued side, before putting them in contact with the corn seeds, then dry them after this contacting.
  • This moistening strips of kraft paper can be achieved by depositing a drop of water with a piezoelectric process of the type already used in inkjet printers. This process has the advantage of not spreading glue outside the kraft paper strip, and do not wet it too much which avoids weakening it.
  • links can also be formed entirely by adhesive material, preferably biodegradable, thermoplastic and / or thermoformable or again by a thread of natural or synthetic material, coated with an adhesive material, preferably biodegradable thermoplastic, and / or thermoformable.
  • Mention may in particular be made of fibers synthetic or natural coated with hot-melts, such as EVA, polypropylene or polyamide, which have a melting point of about 110 ° C.
  • thermoplastic adhesive links With thermoplastic adhesive links, the fixation between these links and the seeds of maize is obtained by heating the links and applying the corn seeds on them, or by contact the links and seeds and then heating them and finally, by exerting pressure on the whole.
  • the links can still be formed by a wire of natural or synthetic material which is coated, discontinuously, with glue, for example thermoplastic.
