Flexible Material Division
FilmA film is usually characterized as a thin synthetic resin layer. There are many types of films and their use depends on their physical and chemical properties, which make them especially suitable for a given application. The most commonly used plastic films are low density polyethylene (LDPE), Polypropylene (PP), bioriented polypropylene (BOPP), and polyester (PET). Printed film is used for packaging, display materials, stickers, seals, and a wide range of other graphic applications. Films are generally characterized by their basis weight, expressed in g/m²; and thickness, expressed in microns. For some films it is also useful to know their density, expressed in g/cm3. The increasing awareness of environmental issues is intensifying research into film substrates derived from renewable sources that are compostable. |

Aluminium foilAluminum is produced from bauxite, an ore abundant in nature. From the rolling mill, aluminum foils emerge with a natural shiny finish, almost as bright as a mirror, but also can be produced with an as-rolled, satin-like finish called matte. Aluminum foil has all of the unique functional characteristics of the aluminum alloy from which it is made. |

LaminatesA laminate is a material that can be constructed by bringing two or more layers of material together. This can include different material combinations from a wide spectrum of flexible substrates including thin aluminum foil, film, and paper. These materials have different physical properties and varying thicknesses that combine to provide the required barrier performance. Converted single- or multi-layer webs are used in a number of industries, from the packaging of food and non food products to industrial applications including the photovoltaic industry. |
