One article to understand open masterbatch!
In the production process of plastic products, open masterbatch plays an extremely crucial role. Perhaps many people are not familiar with it, but it has a real impact on the plastic products we use in our daily lives.
Open masterbatch, also known as smooth masterbatch or anti-sticking masterbatch. From its name, one can roughly guess its function. Yes, it is mainly used to prevent plastic products from sticking together. Its working principle is quite interesting. When added to plastic, on the one hand, it can form a film with excellent lubricity on the surface of plastic products, just like putting on a "lubricating coat" for the plastic. On the other hand, it can also promote the formation of a microscopic concave-convex structure on the surface of plastic products. This convexity and concavity significantly reduce the contact area between plastic products, and the possibility of adhesion also decreases accordingly, thus effectively solving the problem of adhesion of plastic products.
The application fields of open masterbatch are extremely extensive. In the packaging industry, all kinds of plastic film packaging, such as food packaging and daily necessities packaging, cannot do without it. It can ensure that the film does not stick together during bag-making, filling and sealing processes, greatly improving packaging efficiency. At the same time, it can also guarantee the sealing performance and shelf life of the product. In the agricultural field, agricultural films, such as greenhouse films and mulching films, become more convenient to lay and use in the field after adding open masterbatch, avoiding the problem of film adhesion and difficulty in unfolding, and creating a favorable environment for the vigorous growth of crops. In industrial production, industrial products such as plastic sheets and stretch films also require open masterbatches to ensure the smoothness of the production process and thereby improve product quality.
Open masterbatch also has many characteristics. Under normal usage ratios, it will not have a significant impact on the transparency of plastic products, which is crucial for some plastic products with strict transparency requirements, such as transparent packaging films and transparent plastic containers. Through special processing techniques and formula design, the opening masterbatch has excellent dispersibility in the plastic matrix, can be evenly distributed, and avoids situations such as agglomeration and sedimentation of the opening agent, ensuring consistent opening performance in all parts of the plastic product. In addition, the opening masterbatch has excellent chemical and thermal stability. It is not prone to decomposition or deterioration during plastic processing and use, and can maintain its opening and lubricating properties for a long time, ensuring that plastic products always maintain a good opening effect during long-term storage and use.
Although open masterbatch is "low-key", it plays an irreplaceable role in the production of plastic products and brings many conveniences to our lives.
