Abstract
Shellac, a natural resin with centuries of historical use in coatings, adhesives, and varnishes, is emerging as a promising material for addressing key challenges in modern flexible and printed electronics. As the field seeks environmentally friendly, biocompatible, and processable alternatives to petroleum-based polymers, shellac offers a unique combination of favorable properties, including film-forming ability, dielectric behavior, gas barrier performance, and biodegradability. This review traces the path from traditional applications to the current renaissance of shellac in electronic technologies. We examine the chemical composition and structure–property relationships, fabrication methods compatible with printed electronics, and the use of shellac as a substrate, a dielectric layer, a binder in functional printing inks, and a gas barrier coating. With responsible sourcing and a commitment to sustainability throughout the life cycle, shellac has great potential as a foundational component of the next generation of printed, flexible, and environmentally conscious electronics.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
