METALLISED FILM Meaning and
Definition
-
Metallised film refers to a type of packaging material that is coated with a thin layer of metal, typically aluminum. This process involves depositing a thin layer of metallic material onto a film substrate through a specialized vacuum deposition technique. The resulting product is a flexible film with a metallic appearance that offers various advantageous properties.
Metallised film is widely used in the packaging industry due to its excellent barrier properties against oxygen, moisture, and light. The thin metallic layer acts as a protective barrier, preventing the entry of external elements and keeping the contents of the package fresh and secure. This makes it particularly suitable for preserving and extending the shelf life of a wide range of products, including food items, cosmetics, pharmaceuticals, and electronic components.
Furthermore, metallised film offers enhanced aesthetics, providing a shiny, reflective surface that enhances the visual appeal of the packaged product. It is often used for packaging materials that aim to capture consumers' attention on store shelves.
In addition to its barrier and visual properties, metallised film also offers superior heat resistance and can be easily printed upon or laminated with other materials for increased functionality. It is a versatile packaging material that can be easily converted into various formats such as pouches, bags, and labels, making it suitable for a variety of applications.
Overall, metallised film is a technologically advanced packaging material that combines protective and aesthetic properties, making it a popular choice in the packaging industry.
Etymology of METALLISED FILM
The word "metallised film" originates from the combination of the root words "metal" and "film".
The term "metal" comes from the Latin word "metallum", which refers to mines and minerals. It further developed in Old French as "metal" and entered Middle English as "metal" around the 14th century. "Metal" denotes elements or alloys characterized by their high electrical and thermal conductivity, as well as their shiny appearance.
On the other hand, "film" derives from the Latin word "pellicula", meaning a small, thin piece of skin or membrane. In the context of photography and cinematography, "film" refers to a flexible, transparent, and photographic material used for recording images.
Therefore, the term "metallised film" is a combination of these two words, referring to a thin, flexible film that has been coated or laminated with a layer of metal.
