If you are looking for a way to package products quickly and tightly, then you need shrink film. It can be used for primary or secondary packaging of finished goods.
As its name suggests, shrink film is heated, which causes it to shrink and wrap tightly around the product. Heating can be done in a heat tunnel or with an electric or gas heat gun.
Shrink film provides strong and durable packaging for every product.
Types of Shrink Film
Shrink film is mainly divided into three types: PVC, polyolefin and polyethylene shrink film.
These materials can be transformed into multilayer film with different additives in order to achieve better protective properties and a longer shelf life for the product.
Shrink film is most often supplied on rolls, but it can also be available in the form of bags, sheets or other formats.
PVC Shrink Film
PVC shrink film is a relatively sensitive product because at high or low temperatures it becomes brittle and loses its protective properties.
In addition, PVC shrink film may be harmful to human health, both during its production and during use.
In recent years, PVC shrink film has been replaced more and more often by polyolefin and polyethylene shrink film.
Polyolefin Shrink Film
Polyolefin shrink film is a premium packaging material that is highly durable and suitable for universal use.
It is most often supplied on rolls, but it is also available as a sleeve or semi-sleeve.
Polyolefin shrink film is gentle on the machines that heat it, as it does not build up on their components. This ensures easier and more cost-effective maintenance.
Polyethylene Shrink Film
Polyethylene shrink film is the strongest and most durable of the three types, which is why it is used for heavy goods.
It can be printed, which automatically helps reduce labelling costs.
One disadvantage of polyethylene shrink film is that it requires longer heating in order to shrink fully. This creates a risk of melting or damaging products that are sensitive to heat.
Since this film has a very low shrink rate of only around 15%, it is important to be as precise as possible when choosing the correct roll size.
