The shrinkage of molded plastic parts can be as much as 20% by volume, when measured at the processing temperature and the ambient temperature. This volume contraction of polymers often leads to wrapped parts and dimension differences between manufactured parts and the mold (the die if we consider extrusion as the processing technique).

Drawbacks of Polyolefin Shrink Film - Cost and machine compatibility are the two significant Polyethylene shrink film has a low shrink rate of 15% or less.

They shrink due to the normal thermal expansion/contraction caused by heat, of course. But they also have a second shrinkage stage, one that’s particularly pronounced in some semi-crystalline materials (and to a less extent in amorphous polymers). Semi-crystalline polymers shrink at a rate that can be six times higher than amorphous polymers.
