HYMANTOPBON cast film masterbatch can rely on "looks" to eat, but rely on the quality of
  Release time£º2016/9/24

The film has the characteristics of good plasticity, smooth surface, good mechanical strength. Can and BOPP film laminating, printing into exquisite packaging film, the cast film need to have good hiding power, so cast film masterbatch join proportion, color masterbatch requires temperature resistance, excellent dispersibility. The casting production process requirements high temperature extrusion, general feeding section temperature 170 and 190 DEG C, in the middle of the melting temperature of 300 a 315 C, die temperature 280 degrees. The masterbatch demanding, migration resistance high. Explosive packaging film with good effect of cast film, production of explosive film, in addition to the masterbatch, friction coefficient control is essential, otherwise it will produce sticky phenomenon of rail, which will lead to uneven thickness of cast film, production process, because the sticky rail to produce a lot of noise. The main problem is the unreasonable design formulation, Shandong Luyan Color Masterbatch production of cast film color masterbatch fundamentally solves the the problem.
