Shrink film is a versatile polymer material used for packaging finished goods. It's amazing how something so simple can be so effective.

The molecules of a shrink film sheet or tube are randomly intertwined, meaning they're coiled and twisted with no particular alignment. This is what makes shrink film so flexible and adaptable.

Heat is applied to the film, which catalyzes it to shrink tightly around the item placed within. This process can be achieved using a conveyor heat tunnel or an electric or gas heat gun.

The molecular structure of shrink film is what allows it to change shape in response to heat. The molecules reorient from their initial random pattern to fit the mold of their contents.

When cooled properly, the film's molecular characteristics are set, so it remains in this stretched state until sufficient heat energy is applied for the molecule chains to shrink back to their original form.

Shrink film and stretch film may look similar, but they serve very different purposes. Shrink film is designed to shrink when heat is applied, creating a tight seal around items.

Shrink film typically stretches to around 50-75% before breakage occurs, whereas stretch film can stretch up to 300%. This makes stretch film ideal for palletizing multiple items.

The elastic memory of shrink film allows it to cling to itself and keep a tight layer of protection around items. This is a key difference between shrink and stretch film.
