Antiblock additive masterbatches are pivotal in the production of polymer films. They are extremely efficient in all types of films like LLDPE, PP, PVC, PE and other polyolefin films. These antiblocking additives reduce the blocking between polymer surfaces, thereby enhancing the functioning, processing and overall performance of the plastic films. In this blog, we explore the role of antiblocking additives in manufacturing plastic films. 

Why Is It Important to Add Antiblock Additives in Plastic Film Manufacturing?

Blocking is a major problem in the polymer industry. It is a phenomenon where the adhesion of two adjacent layers of the film is due to intermolecular forces. This sticking of films is an issue, particularly in polypropylene and polyolefin films in stacking, winding, processing and handling. To tackle the common plastic film issues, antiblock additives are incorporated in the manufacturing process. 

How to Use Antiblocking Masterbatch to Prevent Blocking? 

The plastic film layers adhere to each other due to the Van der Waals forces. These intermolecular forces cause the polymer layers to stick to each other, increasing the friction between the layers. This undesired adhesion can compromise the quality and performance of the film. The antiblock additives are designed to prevent the adhesion of film layers throughout the development of microasperities on the film surface. These tiny bumps minimize the surface contact between the layers, reducing the molecular forces that cause them to adhere to each other.

The antiblocking agents reduce the COF (Coefficient of Friction), meaning the film layers like less likely to stick together. Incorporating antiblocking additives, plastic film manufacturers can minimize the occurrence of blocking, improve the production process and produce high-quality packaging films. 

Incorporate Natural Silica-Based Antiblock Additive Masterbatches 

Non-migratory additives like natural silica antiblock Masterbatches imply they don’t move around the polymer matrix. For high-clarity and durable films, it is crucial to incorporate premium-quality antiblocking additives. Perfect Colourants & Plastics Pvt.Ltd is an industry-leading antiblock masterbatch manufacturer in USA offering high-performance fine & top-notch silica antiblocking additives. These additives are highly functional even at higher temperatures, making them suitable for commodity as well as specialty films.

The irregular shape of the antiblocking agents allows for high-clarity & low-haze films. They ensure smooth processing and better quality control. Our additives are highly effective in reducing haze in high-clarity applications like food wrap films and medical films.
