Technical Properties
| Property | Performance |
|---|---|
| Antiblocking performance | Reduces blocking of PE/PP film |
| Coefficient of friction | Reduced COF; improved slip |

Recommended Processing Conditions
| Parameter | Recommendation |
|---|---|
| Addition rate | 0.5–2.0% (adjust to actual requirement) |
| Blending method | Dry blend with base resin at the target ratio, then feed directly |
| Process adjustment | No significant change to standard film extrusion settings required |
| Overdose caution | Excess slip agent can cause poor printing ink adhesion, weak heat seal strength, and slip agent migration/blooming. Evaluate and adjust migratory additive loading if the effects appear. |
Applications
Blown PE and PP film is the primary application. Freshly extruded film exits the bubble hot and winds tight, and without an antiblock package the layers fuse enough that the roll tears at unwind. ASM-PE5004 creates the surface microroughness needed to separate layers cleanly, while the slip amide keeps the web moving through the nip and the slitter without drag.
Cast PE and PP film benefits for a different reason. Chill-roll casting produces a smoother, higher-contact surface than blown film, so blocking tendency runs higher at equivalent gauge. The additive package addresses blocking without pushing haze up, which protects the optical clarity that cast film is usually specified for in the first place.
Multilayer co-extruded packaging film uses ASM-PE5004 in the skin layers, where surface behavior is decided. Loading the additive only where it works — rather than through the full structure — keeps the core layer's mechanical and barrier properties untouched and keeps additive cost down. Because the masterbatch disperses well, the thin skin layer stays free of visible gel defects.
Biaxially oriented PE film stretches the additive-loaded melt in two directions, which stresses dispersion quality hard. Poorly dispersed antiblock particles turn into stress concentration points and cause film breaks on the tenter. Controlled particle size and dispersion make ASM-PE5004 workable in oriented film lines where a coarse antiblock package would not survive.
Across all four film types, the 0.5–2.0% addition range gives converters room to tune. Heavy-gauge industrial film with aggressive winding may need the upper end; thin printed food packaging often runs low to protect ink adhesion and seal strength.
Why Choose BASTONE
BASTONE manufactures ASM-PE5004 at its own Hangzhou Economic Development Zone facility. Buyers deal with the company that owns the formulation, runs the compounding line, and holds the batch records — not a trading house that sources from an anonymous compounder and cannot answer a technical question without a phone call upstream. When a converter reports gel count or heat seal issues, BASTONE's R&D center can pull the batch, test it, and adjust.
The group structure supports the product line with four production sites and one R&D center, staffed by chemists who work across polymer additives and specialty chemicals. In-house formulation and testing means BASTONE can develop a variant for a specific resin grade, film gauge, or COF target rather than offering a fixed catalog item and asking the customer to compensate on their own line.
Direct manufacturer supply removes the distributor markup that sits on most masterbatch imported from China. Combined with the export platform operated through Zhejiang Bastone Technology Co., Ltd, buyers get factory pricing alongside export documentation handled correctly the first time — over ten years of export experience, flexible trade terms, and packaging or container loading arranged to fit the destination's requirements.
