High-Performance Slip & Anti-Blocking Masterbatch SILIMER 5065 For PP Films

SILIKE SILIMER 5065 is a high-performance slip and anti-blocking masterbatch based on a PP copolymer carrier, formulated with proprietary copolymerized polysiloxane as the slip component and synthetic silicon dioxide as the anti-blocking agent. It is designed for CPP films, oriented flat films, co-extrusion films, and other polypropylene-based applications.

This super slip and anti-blocking masterbatch significantly improves film smoothness, reduces blocking, and enhances lubrication during processing, lowering both dynamic and static coefficients of friction (COF) for smoother surfaces and better handling. The copolymerized polysiloxane structure ensures excellent compatibility with the resin matrix, shows low migration, and has no precipitation, no stickiness, and no impact on film transparency, making it ideal for demanding packaging applications.

Description

SILIKE SILIMER 5065 is a super slip and anti-blocking masterbatch based on long-chain alkyl-modified siloxane combined with anti-blocking silicon dioxide. It is primarily used in polypropylene films, including CPP films, oriented flat films, and other PP-based packaging applications.

This slip and anti-blocking additive significantly improves film smoothness and anti-blocking performance while providing processing lubrication, reducing both dynamic and static coefficients of friction (COF) for smoother film surfaces and improved handling.

SILIMER 5065 features a specially designed structure with excellent compatibility with the matrix resin, showing no precipitation, no stickiness, and no impact on film transparency.

Benefits

1. Improves surface quality, featuring no precipitation, no stickiness, no impact on film transparency, and no adverse effect on film surface properties or printing performance. It also helps reduce the coefficient of friction (COF) and improve surface smoothness.

2. Improves processing performance, including better flowability and higher throughput during extrusion processing.

3. Provides good anti-blocking and slip performance in PP films, with lower COF and improved processing properties.

Typical applications

Good anti-blocking & smoothness, lower Coefficient of friction, and better processing properties in PP film.

Application Test Results

Placed in a constant-temperature and humidity box at 50°C and 50% humidity to simulate a high-temperature environment.

How to use

To achieve optimal slip and anti-blocking performance, it should be incorporated directly into the surface layer of the plastic film, with a recommended dosage of 1–6%.

Processing Note: Thanks to its excellent processing properties, initial extrusion may release residual material from equipment dead spots, which can temporarily increase the appearance of specks or gel points on the film. This is a transient effect, and film performance stabilizes once steady-state processing is achieved, with no lasting impact on clarity, slip, or anti-blocking properties.

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.

FAQ

FAQ: SILIMER 5065 Slip & Anti-Blocking Masterbatch for PP Films | CPP, Blown, Cast, Co-Extrusion, Oriented Flat Films, Food & Packaging Applications

Q1: What is SILIMER 5065 used for in PP films?
SILIMER 5065 enhances surface slip, reduces blocking, and improves handling in polypropylene films, including CPP, blown, cast, co-extrusion, and oriented flat films.

Q2: How does it improve film processing and surface performance?
It lowers dynamic and static friction (COF), increases smoothness, and provides processing lubrication, supporting easier film opening and better winding performance.

Q3: Is SILIMER 5065 suitable for high-speed production?
Yes, it performs well in high-speed FFS (Form-Fill-Seal) lines and other fast extrusion processes requiring stable slip and anti-blocking.

Q4: Can it be used in food packaging films?
Yes, SILIMER 5065 is suitable for food-contact PP films, including laminated and composite packaging films.

Q5: How should it be incorporated into films?
Add directly to the film surface layer at 1–6% dosage for optimal slip and anti-blocking performance.

Q6: Does it affect downstream processes like printing or heat sealing?
No, it is compatible with printing, lamination, and heat sealing, without impacting transparency, haze, or surface appearance.

Q7: How does SILIMER 5065 prevent bloom or powdering?
Its copolymerized siloxane structure with polar functional groups anchors in the resin, minimizing migration and preventing surface precipitation.

Q8: What types of packaging films benefit most from SILIMER 5065?
Food laminated and composite films, apparel packaging, consumer goods films, industrial packaging, flexible packaging, and other PP-based film systems requiring stable slip and anti-blocking.
