Yes, sandwich bags do help keep food fresh by protecting them from air, bacteria, and contaminants. They are not as effective as some other storage methods like vacuum sealing, but they do provide a basic level of preservation. This information is found on the website of the National Institute of Health (https://www.ncbi.nlm.nih.gov/pmc/arti...) in the section about "Food Storage and Quality" and on the website of the University of Nebraska-Lincoln (https://food.unl.edu/free-resources/n...) under the subheading "Plastic Bags and Wraps".
