As we all know，Polypropylene (PP) film is one of the most widely used thermal plastics in packaging material. With the development of high-performance and function plastics packaging films, additive masterbatch has gradually became an indispensable partner of film because it can improve packaging quality & offer convenience for manufacturing.

what is additive masterbatch and why additive masterbatch is indispensable? Ok，Let's uncover its mysterious veil.

Additive masterbatch, also referred to as a concentrate, is a package for imparting different functions of the film. According to the different use requirements, different kinds of functional additives are  dispersed

into a polymer carrier which is extruded and pelletized. Then those pellets are just additive masterbatch. such as antistatic  masterbatch，slip masterbatch，antiblocking masterbatch and so on. What's more, those pellets metered, or let down, into natural polymer, using a predefined ratio, during the production process. Normal addition rates vary from 1.0% to 4.0%.

Due to the nature of the resin and film, if not add functional agents or materbatch, there will be many problems in the production and subsequent using process of the film, such as rewinding, slitting and other processes. The worst would lead to totally unusable. For example, because PP products are easily accumulated electrostatic charges due to the inherent high insulativity, it may cause troubles such as electric shocks and damages to the electronic machines. In particular, the biaxial oriented polypropylene(BOPP) films are easy to attract dusts and cling together due to the electrostatic charges generated by friction, thus their productivity is influenced significantly. In order to eliminate the static, the way of blending antistatic agents or antistatic masterbatch into the PP matrix is popular under current circumstance. However, film manufacturers are more willing to use additive masterbatch because of the good dispersion, cost saving, environmentally friendly, more convenient to use and other advantages of masterbatch .
