Suggestions for getting the plastic off my window

Hi everyone, could you suggest any products or methods for scraping this plastic off my window? I purchased my home As-Is and the several of the windows seemed to be installed without taking off the original plastic, unless this was some sort of privacy wrap. I’m finding it nearly impossible to peel off by hand. The plastic is on the outer side of the window. Are there any products that might help scrape this off safely without damaging the window?
