Understanding Film Slip and Antiblocking Additives:

Introduction:

In the world of plastic film manufacturing, the performance of the final product is significantly influenced by the use of additives. One such additive that plays a crucial role in determining the film's surface properties is the slip and antiblocking agent. This article delves into what these additives are, their functions, and their impact on the film's performance.

What are Film Slip and Antiblocking Additives?

Film slip and antiblocking additives are substances incorporated into plastic films to modify their surface properties, specifically to reduce friction and prevent adhesion between layers. These additives are essential in the production of films used in packaging, fabrication, and other industrial applications where ease of handling and reduced friction are desirable.

Slip Additives:

Slip additives are used to reduce the coefficient of friction (COF) between films and between film and converting equipment. They enable films to slide more easily over each other, thereby improving the film's movement through extrusion lines and downstream packaging operations . The effect of slip additives is measured by calculating the static or kinetic COF, with lower values indicating a smoother, more slippery surface.

Types of Slip Additives:

Slip additives can be divided into two fundamental classes: migrating and nonmigrating . Migrating slip additives are the most common and must be used above their solubility limit in the polymeric substrate. These additives have a part that is soluble in the organic substrate and a part that is insoluble. Upon crystallization, the slip additive migrates from the matrix toward the surface, forming a continuous coating that reduces the COF . Nonmigrating slip additives are used in very specific cases and are applied externally, providing an immediate slip effect.

SILlKE SILIMER series super slip and anti-blocking masterbatch [https://www.siliketech.com/silimer-series-super-slip-masterbatch/] is a product particularly researched and developed for plastic films. This product contains a specially modified silicone polymer as the active ingredient to overcome the common problems that traditional smoothing agents have, such as precipitation and high-temperature stickiness, etc. It can significantly improve the anti-blocking & smoothness of the film, and the lubrication during processing, can greatly reduce the film surface dynamic and static friction coefficient, make the film surface smoother. At the same time, SILIMER series masterbatch has a special structure with good compatibility with the matrix resin, no precipitation, no sticky, and no effect on the transparency of film. It is widely used in the production of PP films, PE films.

Antiblocking Additives:

Antiblocking additives, as the name suggests, prevent blocking-the adhesion of one layer of film to another, caused by contact under pressure and heat. This adhesion makes it difficult to unwind a film roll or open a bag . Inorganic mineral antiblocks, such as talc and silica, are widely used for this purpose. They roughen the film surface on a microscopic level, preventing adjacent film layers from sticking to each other.

SILIKE FA series product is a unique anti-blocking masterbatch, currently, we have 3 types of silica, aluminosilicate, PMMA ...eg. Suitable for films, BOPP films, CPP films, oriented flat film applications and other products compatible with polypropylene. It can significantly improve the anti-blocking & smoothness of the film surface. SILIKE FA series products have a special structure with good compatibi.

Importance of Slip and Antiblocking Additives:

The use of slip and antiblocking additives is crucial for several reasons. They improve the handling, use, and conversion of films, which can result in increased line speeds and lower waste. Without these additives, films with high COF tend to stick together, making them difficult to handle and use . Additionally, these additives can prevent defects during printing, sealing, and handling.

Conclusion:

In summary, film slip and antiblocking additives are essential components in the manufacturing of plastic films. They enhance the performance of films by reducing friction and preventing adhesion, leading to improved efficiency in production and use. Understanding the types and functions of these additives is key to optimizing film performance and ensuring the quality of plastic film products.
