Blown film masterbatch: The core additive that endows films with color and performance!

In the plastic film processing industry, Blown film masterbatch is an indispensable functional material. It integrates pigments, carrier resins, dispersants and other components through scientific proportioning, specifically adapting to the processing characteristics of blown film technology. It can efficiently endow plastic films with uniform colors while taking into account the mechanical properties and user experience of the films, becoming a key link between raw materials and finished products.

The core advantages of blown film masterbatch lie in "compatibility" and "stability". The blown film process has specific requirements for temperature and melt fluidity. High-quality blown film masterbatches need to be perfectly compatible with film substrates such as polyethylene and polypropylene, and be able to disperse quickly during the blown film process without affecting the blow molding of the film, avoiding problems such as crystal points, color differences, and uneven thickness. Meanwhile, the pigments it contains have undergone special treatment and possess excellent weather resistance and migration resistance. This ensures that the formed film can maintain its bright colors even after long-term use or exposure to light, without fading or discoloration, and will not cause pigment migration to contaminate other items.

From the perspective of application scenarios, blown film masterbatches are ubiquitous in both daily life and industrial fields. In the field of daily packaging, food preservation bags and shopping bags used for food packaging can be dyed with transparent, milky white or multi-color tones through blown film color masterbatches. This not only meets the safety requirements for food contact but also enables the use to be distinguished by color. The waterproof bags and woven bag film layers used for express delivery packaging, when paired with weather-resistant blown film color masterbatches, can maintain a stable appearance even in outdoor transportation environments without affecting the waterproof and load-bearing performance of the film.

The performance requirements for Blown film masterbatches in the industrial field are more detailed. The greenhouse film used in agriculture should be matched with blown film color masterbatch with anti-ultraviolet function. This not only endows the film with the required colors for shading and heat preservation, but also enhances the film's anti-aging ability and extends its service life. Anti-static film for electronic component packaging, blown film color masterbatch can work in synergy with anti-static components, making the film not only have specific color marks but also meet the anti-static requirements, ensuring the safety of electronic component transportation. In addition, for industrial waterproofing membranes, packaging stretch films, etc., different performance blown film color masterbatches will also be selected according to the application scenarios, taking into account both appearance and practicality.

With the popularization of environmental protection concepts and the upgrading of market demands, blown film masterbatches are developing towards environmental protection and functionalization. The environmentally friendly blown film masterbatch adopts a halogen-free and low-VOCs raw material formula, which conforms to the development trend of green packaging. Functional products, by adding special components, endow the film with additional properties such as antibacterial, anti-aging and high-temperature resistance, thus expanding the application boundaries of the film. This diversified development trend not only enriches the colors of plastic films but also provides strong support for the high-quality development of the blown film industry.
