Super Non-Migratory Slip & Anti-Blocking Masterbatch SILIMER 5064MB1 for PE Film Packaging Applications

SILIKE SILIMER 5064MB1 is a super non-migratory slip and anti-blocking masterbatch based on long-chain polar functional alkyl-modified polysiloxane combined with treated anti-blocking agents. It provides a balanced slip and anti-blocking performance through a structure where the functional groups interact with the matrix resin to improve compatibility, while the siloxane segments migrate to the film surface to deliver surface slip.

The formulation exhibits good dispersion stability within the resin system and is designed for low migration performance, with no precipitation and no noticeable impact on film transparency. It also helps reduce both dynamic and static coefficients of friction (COF), improving film handling, winding, and downstream processing performance.

SILIMER 5064MB1 is suitable for PE cast film, blown film, co-extrusion film, stretch, and laminated films used in food, industrial, agricultural, medical, household, and automotive packaging, where stable slip and anti-blocking performance are required.

Description

SILIKE SILIMER 5064MB1 is a super slip and anti-blocking masterbatch based on long-chain alkyl-modified siloxane containing polar functional groups. It is mainly used in PE and CPE films as well as blown film applications. It significantly improves film anti-blocking performance and surface smoothness while providing processing lubrication. It also helps reduce both dynamic and static coefficients of friction (COF), resulting in improved film handling and a smoother surface.

The product has a specially designed structure with good compatibility with the polymer matrix, showing no precipitation, no stickiness, and no impact on film transparency. It is suitable for packaging film systems requiring non-migratory slip and anti-blocking performance.

Benefits

1. When used slip and anti-blocking masterbatch SILIMER 5064MB1 in polyethylene films, it can significantly improve slip and anti-blocking performance, reduce film sticking during processing, greatly lower the dynamic and static coefficient of friction (COF), and maintain film transparency.

2. Under high-temperature or demanding processing conditions, the special copolymerized polysiloxane structure helps maintain long-lasting and stable slip performance.

3. Using copolymerized polysiloxane as the slip component, the product shows good compatibility with the matrix resin and features low migration behavior, helping reduce powdering or bloom-related issues in film products.

4. The film surface slip performance remains relatively stable under high-temperature conditions or before and after curing/aging processes.

5. It has no adverse effect on downstream converting operations such as printing, lamination, and heat sealing.

6. The silicone-containing slip component provides processing lubricity, helping improve extrusion efficiency and processing stability during production.

Typical applications

SILIMER 5064MB1 is a super slip and anti-blocking masterbatch suitable for PE, LDPE, LLDPE, HDPE, MDPE, and mLLDPE films, compatible with blown film, cast film, co-extrusion, stretch film, and selected laminated film structures. It is widely used in food and industrial packaging, agricultural films, stretch wrap, shopping and garbage bags, liners, protective and medical films, and household packaging, especially in applications requiring stable slip and anti-blocking performance.

How to use

To achieve good slip and anti-blocking performance, it should be directly added to the surface layer of the film. The recommended dosage is 1–6%.

Transportation & Storage

This product could be transported as non-hazardous chemical. It is recommended to be stored in a dry and cool area with a storage temperature below 50°C to avoid agglomeration. The package must be well sealed after each use to prevent the product from being affected by moisture.

Package & Shelf life

The standard packaging is a craft paper bag with PE inner bag with net weight of 25kg. Original characteristics remain intact for 12 months from the production date if kept in recommend storage.
