In the world of flexible packaging and film manufacturing, the use of slip agents is common to enhance the processability and surface properties of films. However, due to the migration of the slip agent precipitation, in particular, the amide base and low molecular weight smoothing agent have a serious impact on film printing and other processes.
When slip agents precipitate on the surface of a film, it can lead to a non-uniform surface texture. This unevenness affects the ink adhesion during the printing process. For example, in gravure or flexographic printing, the ink may not spread evenly on the film surface. This results in inconsistent print quality, such as blotches or areas of poor color density. The printed images may lack sharpness and clarity, reducing the overall visual appeal of the printed product.
The precipitation of slip agents can also cause problems with print registration. As the surface of the film becomes irregular due to the presence of precipitated particles, the precise alignment of multiple colors in a printed design is compromised. This misalignment can be especially noticeable in complex multi-color prints, leading to a less professional and less accurate final product.
To mitigate these issues, proper control and optimization of slip agent usage are essential. Manufacturers need to carefully select the type and amount of slip agent, taking into account the specific requirements of the film and the printing process.
SILIKE non-Blooming slip agent, Solve the problem of film precipitation powder, affecting printing and other processing problems.
Due to its composition, structural characteristics, and small molecular weight, the traditional film smoothing agent is easy to precipitate or release powder, which greatly reduces the effect of the smoothing agent, and will seriously affect the subsequent printing, compounding, heat sealing and other processes of the film. The friction coefficient will also be unstable due to different temperatures, and the screw needs to be cleaned regularly, and may cause damage to the equipment and products.
In order to solve this problem, SILIKE’s research and development team has successfully developed a film smoothing agent with non-precipitation characteristics through trial and error and improvement. By optimizing the formulation and preparation process, we have successfully synthesized a smooth agent with high stability and easy precipitation, effectively solving the defects of traditional smooth agents, and bringing great innovation to the industry.
SILIKE non-Blooming slip agent is a modified co-polysiloxane product containing active organic functional groups, and its molecules contain both polysiloxane chain segments and long carbon chain active groups. In the preparation of plastic film, it has the outstanding characteristics of high temperature smooth, low fog, no precipitation, no powder, no impact on heat sealing, no impact on printing, no odor, stable friction coefficient and so on. This product is widely used in the production of BOPP/CPP/PE/TPU/EVA films, suitable for casting, blow molding and drawing processes.
The stability and efficiency of SILIKE non-migratory super slip additives can make it used in many fields, such as plastic film production, food packaging materials, pharmaceutical packaging materials manufacturing, etc., and our company also provides customers with more reliable and safer product solutions.
In conclusion, the precipitation of film slip agents, particularly amide and low molecular weight ones, has a profound impact on film printing. It affects ink adhesion, print registration, ink curing, color accuracy, and the durability of the printed product. By understanding and addressing these issues, the packaging and film printing industries can achieve higher quality printed films and better meet the demands of consumers and end-users.
Therefore, in the film preparation process, it is recommended to choose Non-Migratory Slip Additives to avoid the precipitation of the smoothing agent, which will affect the subsequent processing and quality of the film.
If you want to improve the quality of flexible packaging or other film products, you can consider changing the smoothing agent, if you want to try a film smoothing agent without precipiting, you can contact SILIEK, we have a wide range of plastic film processing solutions.
