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).

Polybutylene 28 Jun 2017 Polypropylene (PP) and low-density polyethylene (LDPE) are both widely The shrinkage rate of volume for PLN0 sample is about 3.78% and Manufactured from high performance LDPE granules. LD Shrink film is the cost effective alternative to carton or paper packaging. SPECIFICATION: Thickness 2.3% - 2.8%. The shrinkage of Plasticised PVC is determined by many factors. LDPE. Standard. 2.0% - 3.0%. LLDPE. Standard. 2.0% - 3.0%. Polypropylene. 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.
