What Is a Blown Film Machine?
A blown film machine is used to produce plastic films for packaging, agriculture, and consumer goods. The process—known as blown film extrusion—involves melting plastic pellets, extruding the molten polymer through a die to form a tube, then inflating it into a thin, uniform film bubble. The film can be flattened into rolls or converted into packaging bags.
Common raw materials include LDPE (Low-Density Polyethylene), HDPE (High-Density Polyethylene), and LLDPE (Linear Low-Density Polyethylene), often combined with additives for improved clarity, strength, or flexibility. Specialty films may also incorporate Nylon, EVA, or Metallocene for enhanced performance.
