Glossary

Polyethylene, abbreviated PE. Extruded durable stretch film with limited resistance to high temperatures, but good barrier properties to moisture.

Polyimide is a durable film that can withstand deformation and destruction at temperatures above 260 degrees Celsius for many hours. It is a stable base for polyimide labels.

Polymer is a complex and relatively large molecule obtained as a result of the reaction of a simpler component with itself.

Polymerization is a chemical reaction involving a catalyst, heat, light, or electron irradiation in which relatively small molecules are linked in chains to form a macromolecule.

Polyolefin is a soft plastic film that is easily deformed by pressure and has good conformability. Examples are polyethylene and polypropylene.
