SILIKE pitches PFAS-free additives for film extrusion and converting

SILIKE Technology outlined a broad additive lineup for plastic film makers on September 14, 2026, in Chengdu, China, targeting slip, anti-blocking and extrusion stability issues across packaging and specialty films. The company is positioning its PFAS-free processing aids and non-migratory masterbatches as a way to improve film quality from extrusion through printing, lamination and final converting.

Why it matters: - Plastic film makers are under pressure to balance slip, anti-blocking, transparency, printability and extrusion stability across the full production chain. - Performance problems can show up later in winding, storage, printing, lamination and converting, which can hurt output and consistency. - PFAS-related regulation and sustainability goals are pushing producers to look for fluorine-free alternatives to traditional processing aids.

What happened: - Chengdu Silike Technology Co., Ltd. said it is offering additive solutions for plastic film production from extrusion to converting. - The product lineup includes slip masterbatches, anti-blocking additives and SILIMER PFAS-Free Polymer Processing Aid, or PPA, solutions. - The company framed the portfolio as a response to film makers' need for stable surface performance and more reliable extrusion behavior.

The details: - Conventional slip systems often use fatty acid amides such as erucamide and oleamide. - Conventional anti-blocking systems often use mineral additives such as silica and talc. - The company said these older systems can create tradeoffs, including blooming, COF variation, contamination, reduced converting consistency and transparency loss. - SILIMER series masterbatches use modified silicone polymers and are designed to provide non-migratory slip and anti-blocking performance for PE blown films, LLDPE packaging films, PP films and multilayer packaging films. - SF series products target demanding applications such as BOPP films, CPP films and other high-performance polymer films. - FA series anti-blocking masterbatches are aimed at reducing film-to-film adhesion while preserving optical properties for PE films, packaging films and transparent films. - FC series low-migratory slip and anti-blocking masterbatches are designed for PE and PP films, including flexible packaging and multilayer structures. - FSE series products are positioned as a cost-effective option for PE and PP films used in consumer goods packaging, industrial films and multilayer flexible packaging. - Silicone-based slip and anti-blocking masterbatches for EVA films are intended for blown, cast and extrusion coating films, with lower odor and less migration-related blooming. - SILIMER PFAS-free PPA products are 100% PFAS-free, fluorine-free and PTFE-free, and are designed for blown film, cast film and multilayer film extrusion. - The PPA solutions are meant to improve melt flow stability, reduce sharkskin and melt fracture, limit die build-up and cut cleaning frequency. - SILIKE said its additive technologies are meant to support packaging films, transparent and high-performance films, and specialty functional films, including MDO-PE, BOPE, agricultural, protective, industrial, EVA functional and TPU films.

Between the lines: - The pitch bundles surface additives and processing aids into one production strategy, which suggests SILIKE is trying to sell film makers on a systems-level approach rather than a single-function product. - The focus on PFAS-free and low-migratory chemistries reflects a broader industry shift toward compliance and cleaner production profiles. - The company is also emphasizing optical clarity and downstream compatibility, which are often the hardest tradeoffs when film makers add slip or anti-blocking agents.

What's next: - SILIKE said film manufacturers can contact its plastic film additive team to discuss production needs and find a suitable additive solution. - The company directed readers to more information and provided contact details for Amy Wang at amy.wang@silike.cn and +86-15108280799. - The portfolio is being positioned for use in blown, cast and multilayer film lines as producers look for alternatives to traditional fluorinated processing aids.

The bottom line: - SILIKE is betting that film makers want fewer tradeoffs between processing stability and surface performance, and that PFAS-free, non-migratory additives can help close that gap.
