With the improvement and development of plastic forming process, With the improvement and development of the plastic forming process, the plastic products become more and more colorful, and the application of pearlescent pigments in the plastics becomes more and more popular. Let us introduce the application of ISuoChem Pearlescent Pigment in plastics according to the processing method of Blow Molding.

Blow molding is the process of forming plastic bottles, cans, and boxes by means of compressed air or vacuuming. The blow molding process includes the manufacture of plastic parisons and the reshaping (blow molding) of parisons. According to different parison manufacturing methods, blow molding has injection blow molding and extrusion blow molding.

Injection blow molding and extrusion blow molding differ in that the former is manufactured by an injection method, and the latter is produced by an extrusion method. In recent years, with the continuous development of plastic forming technology, new processes such as injection draw blow molding, extrusion draw blow molding and multilayer blow molding have emerged.

Blow molding is commonly used in the production of various types of plastic bottles, such as shampoo, conditioner, various cosmetics, liquid soap and mineral water. Pearlescent pigments can be directly blended with resins for blow molding. The general usage is between 0.5% and 3%, depending on the thickness of the bottle wall. A double-layer or multi-layer blow molding can be used to produce a hollow product having a double-layered product wall. The bottle wall is double-layered, the outer layer contains pearly-lustre, and the inner layer is ordinary plastic, which can save cost.

In the plastics industry, the processing methods of pearlescent pigments include Injection Molding, Extrusion Forming, and The Cast Film. If you want to continue to understand, please collect our website or consult us directly, we will update it regularly.
