Solve Critical Film Processing Challenges – With Super Slip & Anti-Blocking Masterbatch
Boost Process Stability, Productivity, and Packaging Efficiency with SILIKE Silicone-Based Slip & Anti-Blocking Solutions
As global Film & Packaging markets continue to evolve toward: high-speed automated production, improved optical and surface quality, stable downstream converting performance, higher efficiency with reduced production costs. film manufacturers are facing increasingly stringent requirements in both extrusion and converting processes.
In modern flexible packaging systems, even minor surface instability can lead to production interruptions, reduced packaging line speed, increased scrap rates, poor end-use performance, and critical Film Processing challenges in extrusion & converting. Film producers and converters commonly encounter recurring issues, including: film blocking during winding, storage, and unwinding, unstable coefficient of friction (COF) over time, surface defects and contamination caused by additive blooming, poor slip performance affecting high-speed packaging, trade-offs among slip performance, anti-blocking efficiency, heat sealing, and printability.
These challenges are particularly evident in: Blown film extrusion (PE, LLDPE, mLLDPE), Cast film, and CPP production, BOPP oriented film systems, Multilayer co-extrusion structures, and High-speed form-fill-seal (FFS) packaging lines. These issues directly impact productivity, yield, and final packaging quality.
To address these challenges, manufacturers traditionally rely on slip agents—typically fatty amides such as erucamide and oleamide—which reduce friction through a migration-dependent mechanism to the film surface. However, this approach often results in slow slip activation, unstable COF over time, and blooming, which may negatively affect heat sealing performance and printability.
Anti-blocking agents are mainly classified into inorganic (e.g., silica, talc, calcium carbonate) and organic types (e.g., PMMA microspheres, crosslinked polystyrene).
Inorganic grades provide effective blocking resistance, good thermal stability, and low cost. However, they may cause optical defects (e.g., white spots), equipment wear, and COF instability due to slip additive adsorption. Some hygroscopic grades can also induce bubbles or streaks.
Organic anti-blocking agents offer better transparency, resin compatibility, and lower abrasion, but suffer from limited thermal stability, higher cost, and potential migration or blooming under processing conditions.
As a result, conventional additive systems often require trade-offs among COF stability, anti-blocking efficiency, optical performance, and process reliability, making it difficult to fully meet the demands of modern high-speed film and packaging applications.

Relevant Performance Test Evaluations
What Film Manufacturers Are Saying About Our Slip & Anti-Blocking Solutions
★★★★★
CPE Film – SILIMER 5064MB2
"During our CPE heat-seal layer film trials, we focused on slip stability after aging because COF fluctuation was a concern in production.
We saw COF drop from around 0.25 to about 0.13 after roughly 20 hours of aging at a 3.5% addition level.
What we observed was that the value stayed stable during continuous running, and we did not see blooming or surface fluctuation.
Adhesion strength stayed around 16 N/15 mm, and sealing performance was not affected. Odor was also lower compared to previous materials."
— Technical Manager, CPE Film Manufacturer
★★★★★
PE Blown Film – SILIMER 5064MB1
"In our PE blown film lamination process, we had clear migration issues with traditional amide slip agents, especially visible as white residue on rubber rollers during lamination.
With the amide system, we saw residue after about one roll (~3,600 m), and it kept increasing with longer runs.
After switching to SILIMER 5064MB1, we ran over 20,000 meters, and the roller surface stayed much cleaner with only minimal traces compared to before.
The difference was very obvious during production and maintenance checks."
— Michael Chen, PE Blown Film Manufacturer
★★★★★
Apparel Packaging Film – SILIMER 6104MB1
"For our apparel packaging films, transparency and cleanliness are critical, especially when packaging dark garments.
Before, we struggled to balance slip performance, transparency, and migration control.
After using SILIMER 6104MB1 at around 2%, we saw COF drop quickly within the first few hours and then stabilize over time.
During high-speed packaging, we did not observe any white powder on film surfaces, even in direct contact with black garments.
Transparency remained within our required range for premium packaging applications."
— Emily Johnson, Garment Packaging Film Manufacturer
★★★★★
Pharmaceutical Packaging Film – SF200E
"For pharmaceutical packaging films, we have strict requirements on particulate contamination and ignition residue.
With conventional amide slip systems, we had issues passing insoluble particle tests, so we evaluated SF200E.
In our trials, we saw improved slip performance suitable for high-speed lines, and no visible particle contamination during testing.
Ignition residue results were also within our acceptable range. In some cases, we also blended it with FA111E8 to improve processing stability."
— David, Quality & Technical Manager
★★★★★
Metallized CPP Film – SF205
"In metallized CPP film production, we had occasional delamination issues during lamination and printing.
We traced part of the problem to migration from conventional slip additives affecting surface condition.
After switching to SF205, we did not see similar delamination during normal production runs.
Surface condition stayed stable for metallization, and we did not observe negative impact on printing or heat sealing.
COF also remained stable during high-speed processing, and we did not see surface powdering."
— Kevin Zhang, CPP Metallized Film Producer
★★★★★
PE Film – Blocking & Openability
"In our PE blown film production, blocking and poor openability have been long-term issues, especially after storage.
We tried adjusting processing conditions, but improvements were limited.
After introducing SILIKE non-migratory slip and anti-blocking masterbatch, we saw clearer improvement in film opening and roll separation.
COF also became more stable during production and storage compared with our previous system.
We did not observe surface powdering, and downstream processing became smoother."
— James Carter, Production Manager, PE Film Converter
