How to choose mouth opening smooth masterbatch
1. Optical performance: In order to achieve better transparency and lower haze, the selection of the opening lubricant should be similar to the refractive index of the resin (1.49), with a narrow particle size distribution and appropriate particle size. Adding a small amount can achieve the desired opening effect.
2. Dispersion: The particle size of anti adhesive agents is crucial. The smaller the particles, the more difficult it is to disperse. The larger the particle size, the more it will affect the surface and optical properties of the film. The particle size of anti adhesive agents is usually 2-10 microns, which requires the masterbatch manufacturer to have a high dispersion twin-screw unit and rich experience in masterbatch dispersion production.
