The tackiness between polyolefin film layers can cause issues during processing and handling. Slip agents are used to reduce interlayer adhesion and improve processability. These additives are categorized into fast slip agents (based on oleamides) and slow slip agents (based on erucamides). The effectiveness of slip agents is measured by the coefficient of friction (COF), which can be low, medium, or high. Many film producers prefer slow slip agents to maintain film compatibility with corona treatment, as slip agents can negatively impact this process.
