ASM-PE6001 Antiblock Masterbatch for PE and PP Film

ASM-PE6001 is a carrier-based additive concentrate built on a polyolefin matrix and loaded with inorganic antiblock agents selected by both particle type and particle size distribution. BASTONE's formulation team screens the antiblock filler for the specific gap that matters in film converting — the mineral has to sit proud of the film surface enough to create micro-roughness and break the vacuum between adjacent layers, but not so coarse that it scatters light or scores the film during winding. Compounding runs on a controlled dispersion process at BASTONE's Hangzhou site, developed specifically to drive the filler into a uniform, agglomerate-free distribution in the carrier.

Dispersion quality is the specification that separates one antiblock masterbatch from another, and ASM-PE6001 targets a low gel count in the finished film. Poorly dispersed antiblock shows up as visible fisheyes and gel specks on a light table, which reject clear packaging film outright. Converters running thin-gauge BOPE or multilayer packaging film see the defect immediately, so BASTONE controls dispersion at the compounding stage rather than asking the film line to correct it.

The grade also resists migration. Antiblock agents that bloom to the surface interfere with adhesive anchoring in lamination and with ink wetting in flexographic and rotogravure printing — a common failure mode when a converter switches masterbatch suppliers mid-program. ASM-PE6001 holds the additive in place, which keeps bond strength and print adhesion stable across the roll and across production lots.

Beyond blocking control, the product lowers the coefficient of friction of the film surface and improves scratch resistance. Lower COF means faster line speeds on form-fill-seal equipment and cleaner unwinding at the converter. Scratch resistance matters where film runs over idler rollers and through slitting stations, particularly in high-clarity applications where surface marring is a cosmetic reject.

BASTONE manufactures ASM-PE6001 in-house rather than sourcing and relabeling it. The group operates 4 production sites and 1 R&D center, and the same laboratory that develops the formulation runs the incoming raw material checks and the outgoing batch testing. Film customers who need a dispersion or gel-count adjustment for a specific line talk to the people who compound the product, not to a trading desk relaying a request upstream.
