With the rapid development of the plastic packaging industry, polyolefin film packaging materials are increasingly broadening the scope of application, the use of BOPP film for packaging production (such as molding cans sealing), friction will have a negative impact on the appearance of the film, resulting in deformation or even rupture, thus affecting the yield.

BOPP film is a bi-oriented polypropylene film, it is a polymer polypropylene as a direct raw material through a series of processes made of film. BOPP film is colorless, odorless, tasteless, non-toxic, and has high tensile strength, impact strength, rigidity, toughness and good transparency, and other characteristics, is an important flexible packaging material, has a “Queen of packaging” reputation. “BOPP film according to its use can be divided into ordinary film, heat sealing film, cigarette packaging film, pearlescent film, metalized film, matte film, etc.

In order to solve the problem of BOPP film’s susceptibility to deformation and breakage, a slip agent is usually added during the film production process. Traditional types of slip agents are synthesized on the basis of fatty acid amino compounds (Primary amide, secondary amide, bisamide). These slip agents migrate quickly to the surface of the film to provide a slip effect. However, these types of slip agents are particularly sensitive to temperature. At a high temperature of 60°C, the coefficient of friction between film and steel, or film and film, increases by 0.5 to double, and therefore can easily lead to packaging defects during high-speed film packaging. In addition, amide-type talcum agents also have the following defects:

● Over time, the amount migrating to the surface of the film aggregates, leading to a decrease in film transparency and thus affecting the appearance quality of the packaging material;

● During film winding and storage, the talc can migrate from the talc layer to the corona layer, thereby affecting the quality of the film for downstream printing;

● In food packaging, as the talc migrates to the surface, it may dissolve in the food, thereby affecting the flavor of the food and increasing the risk of food contamination.

Unlike traditional types of slip agents, the SILIKE Super-slip masterbatch is compatible with polyolefin materials and has excellent thermal stability, giving polyolefin films long-lasting and excellent slip performance. A small amount of SILIKE Slip Silicone Masterbatch SF105 can significantly reduce the surface friction coefficient of the film, effectively solving the defects of amide-type lubricants, such as large changes in friction coefficient, easy to precipitate, and poor thermal stability in the application, Revolutionizing Permanent Slip Solutions for BOPP Films, and improve shark skin phenomenon, solve easy to deformation rupture problem.

SILIKE Super-slip masterbatch, Your Optimal Solution for Plastic Film Flexible Packaging Production!

SILIKE Super-slip masterbatch series products do not precipitate, do not yellow, have no inter-film migration, and do not transfer from the slip layer to the corona layer, avoiding the impact on the corona layer; there is no cross-contamination on the film surface, which is more environmentally friendly and safer. Silicone film opening slip agent series products have stable COF values at a higher temperature, which ensures the stability and reliability of film and packaging processing; at the same time, it can maintain the optical properties of the film for a long time without affecting the subsequent process of printing, aluminum plating, etc. It is widely used in polyolefin films such as CPP, BOPP, PE, TPU, EVA, and all kinds of flexible Packaging…
