Description

Technical Field

[0002] Stretch film is also called stretch film and heat shrink film. Stretch film production is a manufacturing process that involves processing plastic raw materials into thin films and using them for packaging, protection or other purposes. The specific steps are as follows: Put the prepared plastic particles into the extruder and melt them by heating and pressure, and extrude them through the extrusion port of the extruder to form a continuous film sheet. After the film is extruded, it is cooled by a cooling roller or a cooling air flow to solidify its structure. The cooled film passes through a stretching device and is stretched by a series of stretching rollers to change its physical properties and performance. After the stretching is completed, the film is wound up by a winding device to form a roll-shaped film roll.
