When it comes to plastic manufacturing, there are lots of processes undergo before the final product comes out. Along with, there are various materials being used during the manufacturing as each of them plays a crucial role in determining the final quality of the product. One such material is masterbatch. Polythene is typically natural in colour and Masterbatches are used to add colour to it.
Different kinds of Masterbatches are used to give the polythene its opacity of colour. For a hint of colour, 1-2% is found to be sufficient. For dark colour, the masterbatch percentage varies between 6-12%. It is important to note that there are certain colours that have good opacity properties e.g., white cannot be opaque so co-ex needs to be made with a colored inner layer.
Besides coloring, there are many other advantage of Additive Masterbatches. They result in increasing effectiveness against Fungi, Yeast, Algae and Bacteria. In addition, they also deliver more strength to plastic. Other properties are scratch resistance, strength enhancer, and brightener etc. The only thing one needs to take care of is to choose a reliable supplier of Masterbatches. A thorough research is much needed for this job and today internet opens up many possibilities for further research that would actually help in finding the best supplier.
