PRINTING TECHNOLOGY COMPATIBILITY AND GERMINATION VIABILITY OF SEED PAPER AS A SUSTAINABLE PACKAGING INSERT MATERIAL

The article investigates the feasibility of replacing traditional packaging inserts made from PVC foam and corrugated cardboard with biodegradable seed paper, transforming inert packaging waste into a viable biosystem. The study presents experimental data on print quality obtained with a spectrodensitometer and surface microstructure analysis conducted by optical microscopy, justifying the selection of screen printing as the optimal technology for seed paper substrates. A structured analysis of admissible and inadmissible printing and finishing technologies for seed paper is provided, supported by seed germination testing conducted under standardised laboratory conditions.
