Additive Masterbatch Plast Antiblock

Each type of additive masterbatch has some special properties to improve the end plastic product.

ANTI BLOCK ADDITIVE

Significance

Anti-block additives are used to reduce blocking at the surface of polymer films and other plastic articles in order to allow easier processing and handling. Traditional anti-blocking additives, such as silica or talc, work by reducing polymer to polymer contact (distance between film layers is maximized ) and micro-roughening of the surface is enabled. The slip and antiblock effects are confined to finished plastic parts, often from the range of Poly olefins. Slip properties enable two surfaces to slide more smoothly over each other, while antiblock properties reduce the adhesion of two surfaces.

How it Works

Polyolefin films tend to adhere to each other due to strong interaction or electrostatic charges when being in close contact (adjacent layers). The higher the temperature, pressure, and contact/processing time, the higher the tendency to stick to each other.
To avoid the adherence of layers due to a close contact, Anti block additives are introduced into the film in a highly diluted concentration. We ensure that those minerals incorporated in it have little / no impact on the mechanical properties of the film; must not deteriorate transparency, haze, color, gloss of the film; and should be compatible with the blown film extrusion process.

Mechanism

Blocking is frequently occurring phenomenon of adhesion between two adjacent layers of film. It is a problem most associated with PE and PP films (either blown or cast) and to a lesser extent in extrusion coated or laminated products.

Know more

It is thought that blocking of adjacent film layers occurs due to the presence of Van der Waal’s forces between the amorphous regions of the polymer which increases with reduced distance between the two layers, thereby increasing blocking of two layers when pressed together (ie) winding onto a take up roll ,stacking of finished, converted films . Another possible reason for blocking is the presence of low molecular weight species (such as oligomers), which tend to migrate to the surface of the film.

Characherstics

An antiblock additive present in the resin microscopically protrudes from the film surface. This creates asperities (i.e. “little bumps”), which help to minimize the film-to-film surface contact, increasing the distance between the two layers, thereby minimizing blocking.

Know more

The blocking between adjacent layers results in increased friction (resistance to motion) and the addition of an antiblock contributes to a reduction in the film-to-film coefficient of friction (COF). COF is a measure of the relative difficulty with which one surface will slide over an adjoining surface. The greater the resistance to sliding, the higher the COF value, for instance ‘low-slip’ or ‘no-slip’ film, sometimes referred to as ‘high COF’ film.

Our Speciality

We do offer speciality grade Antiblock additives which has uniform spherical shape and very narrow particle size distribution . They do impart good transparency and low CoF to the film. They are used in products where there is a demand for high-tech features and complex applications (high-end).

We are well known as a reliable partner for our clients who are converters for leading brands in Flexible Packaging as our White masterbatches are well suited for Blown film extrusion of Mono layer as well as Multilayer films

Plast Antiblock
for
PE FIlm

PE film is also called stretch film, stretch film, and stretch film. PE film is mainly widely used in centralized winding packaging of various goods. It can reduce the damage and collapse of the goods during the transportation process.

Plast Antiblock
for
Multi Layer Film FIlm

Multi Layer film has the combination of skin & core layers with diverse film properties , significant capabilities and cost advantages when compared to conventional 2 or 3-layer films. It has wide applications in collation shrink films , laminates , edible oils, ghee, etc.

Plast Antiblock
for
Mulch Film

Plastic mulch films are used for weed spread control and water retention in crop production and landscaping. Plastic mulch film also acts as a barrier to keep fumigants efficiently in the soil instead of being released into the atmosphere.
