Stretch Film LDPE/LLDPE plastic inflation making machine: KML-45S/55S

Film Width500-900 mm
Screw Dia.Ø 45/55 mm
Suitable MaterialLDPE/LLDPE
The KML-45S/55S model LDPE, LLDPE stretch film making machine is a device used to produce stretch films made from linear low-density polyethylene (LLDPE) pellets. The machine uses a process called blown film extrusion to produce the films. Blown film extrusion is a process where a plastic melt is extruded through a circular die, and a bubble is formed using air pressure. Air is then blown into the extruded film tube, creating a bubble. The bubble is expanded until it reaches its maximum diameter, after which it is collapsed and wound onto a roll, producing a flat film.

The machine's speed, temperature, and other parameters can be adjusted to control the film's thickness, width, and other properties. For example, increasing the air pressure during the bubble forming stage will result in a thinner film, while reducing it will produce a thicker film.
