Plastic is a superior packaging material. It delivers superb cleanlines and posibility to use packaging gas(Nitrogen) in automated lines. Cleanliness is essential for shelf life, and many products have it now unheard compared to 80s paper packaging - only due to package. Amount of food spoilage prevented by plastic packaging is enormous, it is very sad to see this no plastic hysteria. Like seing dark ages returning.
I agree with you. Plastic is one of those weird issues where it gets much more prominence than it deserves. Plastic reduces food waste and items damaged in shipping. If you don't litter and have a good landfill system, there is nothing to worry about.
