This BOPP film antistatic modifier is based on saturated alkyl bis(hydroxyethyl)amine, a nonionic amine‑type antistatic additive tailored for biaxially oriented polypropylene (BOPP) film production. It withstands the severe thermal conditions of BOPP extrusion and sequential stretching process. After film solidification, active components migrate moderately toward the film surface to build a thin hydrophilic conductive layer for static dissipation. Its low‑bloom characteristic avoids heavy surfa

Product Detail

Product DetailsSaturated alkyl bis(hydroxyethyl)amine is an amphiphilic non‑ionic molecule. Long saturated alkyl chains provide good compatibility within poly‑propylene matrix, while two hydroxyethyl groups deliver hydrophilic functionality for static dissipation. It can be either directly metered during extrusion feeding or compounded into PP‑based antistatic masterbatch before BOPP film manufacturing.

During BOPP production, the resin melt undergoes high‑temperature extrusion, longitudinal stretching and transverse stretching. This antistatic modifier exhibits high thermal stability and resists thermal decomposition under the high processing temperatures required for BOPP stretching. Volatile decomposition fumes and die deposits are minimized, reducing film defects such as fisheyes and streaks.

After the finished BOPP film is cooled and wound, the antistatic molecules migrate gradually outwards to the film surface. The hydrophilic hydroxyethyl segments orient outward and absorb trace ambient moisture to create a continuous micro‑conductive surface layer, dissipating static charges generated during unwinding and converting operations. Moderate migration speed delivers the core low‑bloom advantage. Excessive surface deposition is prevented, so the film surface maintains proper surface energy. It does not inhibit ink anchoring during printing and does not weaken adhesive bonding strength in lamination procedures.

Being a migratory nonionic antistatic additive, its antistatic effectiveness is humidity‑dependent. Antistatic performance declines under extremely low‑humidity environments. Even though it is formulated for low bloom, over‑dosage will still cause surface exudation, slippery film surfaces and reel blocking. It will also degrade printing ink adhesion and lamination bond strength. Insufficient dosage cannot achieve target surface resistivity for static control.

Special attention must be paid to processing temperature profile for BOPP lines. Although thermal stability is improved, prolonged residence time inside extruder barrel should still be avoided to prevent gradual degradation.

The typical recommended dosage ranges from 0.35 wt%‑1.3 wt% calculated on total PP resin weight. Pre‑production laboratory evaluation needs to cover thermal stability, extrusion fouling tendency, surface resistivity evolution with ageing, anti‑blocking performance, surface tension retention, printing ink adhesion and lamination peel strength of finished BOPP film.

Store the BOPP film antistatic modifier inside sealed moisture‑proof bags in cool, dry and ventilated warehouse. Avoid prolonged storage under elevated temperature to prevent softening and caking. Keep away from direct sunlight. Reseal packaging immediately after opening to guarantee consistent feeding behaviour and antistatic performance for BOPP production.
