Reviewer 2 Report
1. The author mentioned "100% power and 4 m/s speed", may use the data with units more clear, such as 15KW. In addition, please confirm the data in abstract, 4 m/s ? 4 m/min?
2. Figure 3 showed the difference before and after plasma treatment, please add statistic analysis of PET surface roughness.
3. Why the samples modified with KAc have better performance? what is the mechanism?
4. Adding some images of contact angle test may increase the visual effect of this manuscript.

Reviewer 3 Report
The present manuscript is focused on exploitation of Atmospheric Plasma Treatment and UV polimerization in order to enhance the hydrofilicity of PET substates so as to gain anti-adhesive surfaces. The optimal experiment parameters for atmospheric plasma were evaluated as well a further modification by UV grafting was carried for the purpose of improving the durability to ageing. Since this approach could be taken as a starting point to confer anti-bacterial properties to materials used in medical fields, I have some minor suggestions and comments to improve the current state of manuscript.
#1 Please write the name of bacteria in italics.
#2 In the Conclusions section the Authors should point out the main findings of the study. Please re-write this Section moving the parts of comparison with the literature in the Introduction part or in Discussion section.
#3 Did the Authors evaluate the PET anti-adhesiveness using a Gram-positive bacteria strains?

Round 2
Reviewer 1 Report
Review of coatings-2264317 entitled Atmospheric Plasma and UV Polymerization for Developing Sustainable Anti-Adhesive Polyethylene Terephthalate (PET) Surfaces
In my opinion, the article should be published after minor revision. The article has been revised and the authors have taken into account the reviewer's suggestions. The manuscript has been significantly improved. However, the paper still contains some minor editing errors that should be corrected.
Below are my comments:
1) Now the reviewer knows from the description of the plasma reactor that a commercial industrial material treatment device was used for the study. Thus, a power of 15 kW is acceptable and understandable.
2) Page 3, lines 137-138: The type of device can be put in brackets, this will make the text easier to understand.
3) Page 4, line 140: Isn't there a missing unit with the angle value?
4) Page 4, line 141: The unit of pressure is misspelled. It should be “Torr” instead of “torr”.
5) Page 6, line 214: What is the purpose of using a p-value of 0.0003? What motivated its selection?
6) Page 10, Table 5: Missing space between parameters SFE Polar and SFE Total parameter names, making them confusing to read.
7) Page 11-12: The caption of Figure 7 is on a different page than the figure itself.
