Black masterbatch for blown film

JOYBLACK® series blown film black masterbatch from Jiucai New Materials is produced using pigment carbon black and virgin carrier resin. It features high carbon black content, high blackness, low odor, good dispersibility, good consistency, and good stability. It is used in blown film and casting processes for polyethylene (LDPE, HDPE, LLDPE) films to produce agricultural films, mulch films, silage films, greenhouse films, shopping bags, garbage bags, industrial and building films, composite films, and surface protective films, etc.

Blown film, also known as blown film process, is a process that involves heating and melting plastic particles and then blowing them into a thin film. This process typically involves first extruding the polymer to form a tubular preform, then inflating the preform to the desired thickness using high-pressure air, and finally cooling and shaping it into a thin film.

I. Product Advantages:
