I am looking at the Merriam Webster definition of "film"
In its point 3. it says "b (1) : a thin flexible transparent sheet (as of plastic) used especially as a wrapping"
How common is this usage? I am a bit reluctant to use this word, and instead prefer using "wrapping"
EDIT: I am using the word to meaning packing small objects such as candies on a series of packages of several materials (can be plastic, or paper, etc)
