Antiblock Masterbatch, also known as slip-resistant or anti-blocking masterbatch, is used to prevent two adjacent film layers from sticking or "blocking." This allows films that naturally stick together to be easily separated during winding. In today’s competitive market, key considerations include: ultimate blocking strength, resulting haze, and cost.
| Appearance | Uniform particles/ Customizable size |
| Supported Resins | PE/PP/ PET/ PA/ TPU, etc. |
| Active Ingredients | Inorganic / Organic agents |
| Recommended Dosage | Normally 2%–8% |
| Regulations | RoHS, REACH, FDA |
Inorganic additives, such as silica and talc, offer high temperature resistance and low migration, making them suitable for high-transparency films.
Performance Comparison Table – Inorganic Antiblock Masterbatches
Material Type | Anti-Stick Properties | Transparency | Cost | Applicable Film Types | Migration | Processing Temperature Adaptability |
Diatomaceous Earth | Excellent | Fair | Low | General Film, Industrial Film | None | Good |
Talc | Good | Fair | Medium | General Film, Industrial Film | None | Good |
Nepheline Syenite | Fair | Excellent | Medium | High Transparency Film, Food Packaging Film | None | Good |
Engineered Material | Good | Excellent | High | High Transparency Film, Pharmaceutical Packaging Film | None | Excellent |
Organic additives, such as oleamide and erucamide, migrate on the film surface to form a lubricating layer, making them suitable for applications requiring a low coefficient of friction.
Performance Comparison Table – Organic Antiblock Masterbatches
Performance Dimensions | General Organic Anti-Stick Masterbatches (e.g., Oleamide, Stearamide) |
Anti-Stick Performance | Average, usually lower than inorganic motherbatches |
Transparency | High, suitable for high-transparency films |
Cost | Medium, usually higher than inorganic motherbatches |
Applicable Film Types | Ultra-thin films, food packaging films, pharmaceutical packaging films |
Migration | Possible migration, food contact regulations must be considered |
Processing Temperature Adaptability | Good, suitable for standard processing temperature ranges |
Combining inorganic and organic additives achieves both high transparency and low friction, offering a balanced solution for demanding applications.
Antiblock Masterbatch is widely used in plastic film production, including:
• Food packaging films
• Pharmaceutical packaging films
• Industrial packaging films
• Daily plastic bags / shopping bags
• Engineering plastic films / sheets
Standard's anti-stick master batch can forms fine bumps on the film surface. That allows air to enter between film layers, effectively reducing sticking. We can guarantee you that all masterbatches are quite stable.
Standard's formulation has been refined numerous times to maintain both anti-sticking properties and the desired clarity of the film.
Standard's anti-stick masterbatch offers excellent heat resistance and operates stably at temperatures up to 300°C. That is why we can greatly avoid migration or performance degradation.
Standard can provide customized solutions based on clients’ requirements. From film thickness, target coefficient of friction, haze level, to the need for double-sided anti-sticking, we have mature formulas.
Standard's anti-blocking masterbatch can pass international standards such as RoHS, REACH, and FDA. It is suitable for global markets.
In addition to anti-blocking masterbatches, Standex offers a variety of functional masterbatches to meet different film and plastic product requirements:
• Anti-UV Masterbatch
• Slip Masterbatch
• Antistatic Masterbatch
• Flame Retardant Masterbatch
• Color Masterbatch
• Optical Brightener Masterbatch
