Film masterbatch is a type of color masterbatch that is used to add color to plastic films in a variety of industries, including packaging, agriculture, and construction. It is typically composed of high-quality pigments and carrier resins that are dispersed evenly throughout the plastic film during the extrusion process.
Film masterbatch is added to plastic film through a process called extrusion. The masterbatch is first mixed with the plastic resin pellets and then melted together in an extruder. The molten mixture is then passed through a die to form a thin film, which is then cooled and wound onto a roll.
Film masterbatch is used to produce a wide range of plastic films, including packaging films, agricultural films, construction films, and industrial films. These films can have various properties such as UV resistance, antistatic properties, antimicrobial properties, and flame retardance, among others, depending on the type of masterbatch used.
The shelf life of film masterbatch depends on the type of masterbatch and the storage conditions. Typically, most film masterbatch has a shelf life of 12 to 24 months when stored in a cool, dry, and well-ventilated area, away from direct sunlight, heat, and moisture, and in its original packaging.
When choosing a film masterbatch, considerations include the type of polymer used in the film, desired properties of the film, such as color or additives, processing conditions, and end-use application requirements, such as durability or barrier properties. It's also important to consider the compatibility and dispersibility of the masterbatch with the polymer.
