What is the main material of the PP lunch box black masterbatch?

The main materials of PP lunch box black masterbatch typically include the following:The main materials used in PP lunch box masterbatch are typically:
1. Carrier resin
The carrier resin in PP lunch box black masterbatch is usually polypropylene (PP) itself.The carrier resin used in PP lunch boxes black masterbatch is usually Polypropylene (PP). This is because the masterbatch is designed to be used in PP - based products like lunch boxes.The masterbatch was designed to be used with PP-based products such as lunch boxes. Using PP as the carrier resin ensures good compatibility with the base PP resin of the lunch box.Using PP to carry the carrier resin ensures compatibility with base PP resin in the lunch box. It allows for easy dispersion of the other components within the masterbatch throughout the PP matrix during the processing of the lunch box.It allows for the easy dispersion throughout the PP matrix of the other components in the masterbatch during the processing of a lunch box. For example, when the black masterbatch is added to the PP resin during injection molding or thermo - forming of the lunch box, the PP carrier resin can blend seamlessly with the main PP material, maintaining the mechanical and physical properties of the final product.When the black masterbatch, for example, is added to PP resin in the injection molding or thermo-forming of the lunchbox, the PP carrier can blend seamlessly with main PP material and maintain the mechanical and physical characteristics of the final product.

2. Pigment - carbon blackPigment - Carbon black
Carbon black is the key pigment in black masterbatch.Carbon black is a key pigment in the black masterbatch. There are different types of carbon black, such as furnace black, lamp black, and acetylene black.Carbon black comes in different forms, including lamp black, furnace black, and acetylene. For PP lunch box black masterbatch, furnace black is often preferred due to its good color strength, dispersion properties, and cost - effectiveness.Furnace black is a popular choice for PP lunchbox black masterbatch due to its color strength, dispersion characteristics, and cost-effectiveness. Carbon black provides the intense black color to the masterbatch.Carbon black is responsible for the masterbatch's intense black color. It has a high refractive index difference compared to the transparent or semi - transparent PP resin, which makes it highly visible and able to absorb light effectively, resulting in a deep black appearance.It has a higher refractive index than the transparent or semi-transparent PP resin. This makes it highly visible, and able absorb light effectively. Additionally, carbon black can also enhance some properties of the PP lunch box.Carbon black can also improve some of the properties of a PP lunchbox. For instance, it can improve the UV resistance of the lunch box.It can, for example, improve the UV resistance. When exposed to sunlight, the carbon black can absorb UV rays, preventing the degradation of the PP resin and thus extending the service life of the lunch box.Carbon black absorbs UV rays when exposed to sunlight. This prevents the degradation of PP resin, extending the life of the lunchbox.

3. Additives
There are various additives in the black masterbatch.The black masterbatch contains a variety of additives. Dispersants are an important type.Dispersants are a type of important additive. They help to break down the carbon black aggregates into smaller particles and keep them evenly dispersed in the carrier resin.They break down the aggregates of carbon black into smaller particles, and keep them evenly distributed in the carrier resin. This is crucial as good dispersion of carbon black ensures a uniform black color in the PP lunch box.This is important because a uniform black color will be achieved in the PP lunch boxes with a good dispersion. If the carbon black is not well - dispersed, there may be color streaks or uneven coloring in the final product.If the carbon is not evenly dispersed there could be color streaks in the final product. Another type of additive is antioxidants.Antioxidants are another type of additive. Since the PP resin can be oxidized during processing and use, antioxidants are added to prevent this oxidation.Antioxidants are added because the PP resin is susceptible to oxidation during processing and usage. They can react with free radicals generated during oxidation, protecting the PP resin from degradation, maintaining its mechanical properties, and also preventing the discoloration that may occur due to oxidation, which could affect the black color quality of the lunch box.They can react with the free radicals produced during oxidation. This protects the PP resin, maintains its mechanical properties and prevents discoloration due to oxidation.
