Introduction to Blown Film Line
A blown film line is a crucial piece of equipment in the plastic processing industry. It is used to produce plastic films by extruding molten plastic through an annular die and then inflating it into a bubble. The bubble is cooled and collapsed to form a flat film, which can be further processed for various applications such as packaging, agriculture, and construction. The blown film line typically consists of an extruder, a die, a cooling system, a haul - off unit, and a winder. Different types of blown film lines can produce films with different thicknesses, widths, and properties, depending on the requirements of the end - users.
