Decorative Glass Film A film which, due to its surface structure, attains the impression of etched or sand blasted glass. Often even a different feel to the film is obtained through different embossing on the surface of the film.
Densitometer The optical density of colors is determined by the densitometer. With the help of a photodiode or photo cell, a ray of light is passed through materials and it is measured whether the ray of light is reflected or if it passes right through. The optical density is calculated from the relationship between the irradiated light beam and the measured light beam. Densitometers are standardized on default settings, which conform to the sensitivity of the human eye, the standard ink or UV sensitive materials.
DPI The abbreviation stands for dots per inch. DPI is the unit of measurement for the resolution of output devices such as printers. For monitors, it is more correct to refer to PPI         (pixels per inch).
E-Cut Abbreviation of the term 'electro cut'. Ultimately, all films that can be plotted are summed up under this category.
Edge Protection In different uses of films, edge protection is perhaps sensible or even essential. Thus an edge protector is recommended for the long-term use of perforated window films in order to stop the penetration of dust, dirt and moisture into the cut edges of the film. Also in instances where the film is exposed to high tractive forces (e.g. wind speeds), an edge protector can extend the service life of the film. The edge protection can also be applied as a protective lacquer or in the form of a protective laminate, which is bonded to the background film with an overlap of approximately 1cm.
Extrusion

Certainly the most commonly used machine in the polymer industry is the extruder. Prior to extrusion the raw material components are mixed in roller mills and then granulated. The granulate is the starting material for the extruder and/or the calender.

In the extruder the granulate is heated to a temperature which allows it flow. Then it is pressed through a nozzle and transported to the calender. There the material can be rolled to the desired width and thickness, and is cooled.

Film Lamination

In film lamination the adhesive is applied to the backing paper and dried. Then the screen of film is laminated onto the adhesive-coated backing paper.

Film Remover Films that are difficult to remove due to the permanent adhesive used and longer hold of the adhesive can be effectively removed using a film remover. The remover fluid is applied thinly and evenly to the surface of the film that is to be removed using a brush or roller. For hard-wearing inks or varnishes on the film it is recommended that you first rub down the surface with sandpaper before applying the remover liquid. After approximately 15-20 minutes the film is ready to be removed. Furthermore, warming the film using hot air equipment makes it easier to pull off.
Fire Protection Classification B1 Fire retardant materials include: wood materials treated with a fire retardant, hard foam plastic. A fire must extinguish itself after the fuel source of the fire has been removed.
