Question
What is the process that films go through after film is made that makes the film into shrink film?
Expert Solution

Step 1
Nowadays shrink wrap is a very common polymer used for the packing of finished goods and many other objects also.
The molecular structure of the shrink film is randomly intertwined means they are coiled and twisted with no particular alignment.
Most of the shrink films are made of high-pressure low-density polyethylene or simply known as LDPE. Autoclave resin with melt indices is used to increase the shrink properties of the film.
