1.Dispersibility: The film products made of high-dispersibility masterbatch have uniform color everywhere, without spots or marks. For ordinary blown film masterbatch, when the film product has 3 layers, the product color is uniform and there is no problem. When it is increased to 5 layers, the probability of product problems increases significantly, and the color distribution uniformity of blown film products is seriously reduced. , When it is increased to 7 layers, the disadvantages of ordinary blown film masterbatch are clearly displayed, and it is impossible to make a good finished product.
2.Concentration: The thinner the film product, the weaker the coloring effect of the same masterbatch concentration. When the color does not meet the requirements, the amount of masterbatch needs to be added. Blown film products cannot increase the filling amount of masterbatch indefinitely, which will have an impact on the film products.
3.Coloring ability: the toner is different, the coloring ability is different, the higher the coloring power, the higher the cost. For example, coloring into a yellow color with the same color depth, for masterbatch products of different quality toners, the same density, the color depth after coloring is quite different.
4.Compatibility: For blown film products, the process of multilayer blown film itself is quite difficult. After adding color masterbatch, the physical and chemical properties of the product will be changed. The compatibility of color masterbatch with plastic raw materials will be Lead to a decline in the film blowing performance of the raw material.
5.Heavy metal content and safety: Especially for food packaging films and pharmaceutical packaging films, the products need not contain any heavy metal substances, and the various raw materials in the masterbatch must meet the standards.
6.Stable color: In the process of using film products, the light resistance and migration resistance must meet the standards of use.
