These shrink characteristics are built into the film during its manufacture by stretching it under controlled temperatures to produce orientation of the molecules (Chapter 5). Upon cooling, the film retains its stretched condition, but reverts towards its original dimensions when it is heated around the package.
Heat-shrinkable film is a type of material that can be fabricated from similar substances as shrinkable tubing, produced through extrusion and irradiation, and used widely in food wrap, packaging, and manufacturing processes. You might find these chapters and articles relevant to this topic. T.J. Cowell, in Metallocene Catalyzed Polymers, 1998
A very popularly used product is shrink wrap forming for packaging all kinds of products. The strains developed in a plastic film are released by raising the temperature of the film, thus causing it to shrink over the package where the packaged product acts as a mold.
As in industrial shrink film, heat causes the polymer molecules to relax, causing the film to return to its original unoriented size and shrink tightly around the packaged goods. Since the polymer molecules in oriented shrink film are much more highly oriented, greater shrinkage may be obtained.
The latter is the focus of this paper. The conventional blown shrink film market is dominated by high pressure low density polyethylene, LDPE. The most typical LDPEs used in this application are autoclave resins with melt indices around 0.4-0.7 g/10 min and tubular resins with melt indices around 0.2-0.3 g/10 min.
Small holes may be poked in the film before wrapping to allow air to escape while the film is shrinking. As in industrial shrink film, heat causes the polymer molecules to relax, causing the film to return to its original unoriented size and shrink tightly around the packaged goods.

Products Description . After the battery pack assembled, it needs to be film-wrapped and a layer of plastic film is pasted on the surface of the battery pack. Use a heat shrink film shrinking machine to stick the heat shrink film on the battery pack. The heat is generated by heating, and the plastic film will shrink after the heat and tightly wrap around the outside of the battery pack.
