Shellac: From Isolation to Modification and Its Untapped Potential in the Packaging Application

Round 1

Reviewer 1 Report

The authors presented an original review on shellac. The article is well written, contains a sufficient number of sources, necessary comparative tables and bibliographic analysis.

However, there are a number of minor remarks:

1. The title of the article, one of the functions of packaging is isolation. In this regard, I sit to reconsider the name.

2. Conclusion: the first paragraph is of a general nature, the second paragraph contains a description of the unique features of the material, the third contains generalizing material about the use of shellac in packaging. The structure of the conclusion needs to be made more consistent.

3. The annotation needs similar processing.

After these minor changes, the article can be published.
