Polymer layers have the tendency to stick to each other when they are subjected to a close inter-surface contact. This is due to the presence of strong Van der Waals force or electrostatic charges between the amorphous regions of the polymer. These forces increase exponentially with a reduction in distance between the two polymer layers during the stacking of converted, finished films or winding onto a take-up roll. The measures to prevent film sheets from sticking together are termed as antiblocking. These additives are added to the polymers in a concentration of 1,000 ppm to 6,000 ppm, during the extrusion phase, to avoid the blocking or adhesion of layers. The dosage of antiblocks varies according to the film thickness, film grade, additive used, and extrusion conditions. Antiblock additives protrude microscopically from the film’s surface and create little bumps, thereby increasing the friction and minimizing the film-to-film surface contact or blocking. The purpose of adding antiblock additive is to reduce the smoothness of polymer film layers, so as to negate the blocking tendency. These additives function under the adverse pressure and temperature conditions during the storage, manufacture, or use of film layer.
Visionary leaders are the leading market players in terms of new developments such as product launches, innovative technologies, and the adoption of growth strategies. These players have a broad product offering that caters to most of the regions globally. Visionary leaders primarily focus on acquiring the leading market position through their strong financial capabilities and their well-established brand equity.
Dynamic Differentiators are established players with very strong business strategies. However, they have a weaker product portfolio compared to the visionary leaders. They generally focus only on a specific type of technology related to the product.
Innovators in the competitive leadership mapping are vendors that have demonstrated substantial product innovations as compared to their competitors. The companies have focused on product portfolios. However, they do not have very strong growth strategies for their overall business, when compared with the visionary leaders.
Emerging companies have niche product and service offerings. Their business strategies are not as strong as that of the established vendors. The emerging vendors include the new entrants in the market, emerging in terms of product portfolio and geographic reach, and require time to gain significant traction in the market.
