- Single-Layer LDPE Blown Film Extrusion Machine (200-600 mm)
产品详细信息
The Single-Layer LDPE Blown Film Extrusion Machine melts LDPE resin, extrudes it through a circular die, inflates and cools the film bubble, then collapses and winds the tubular film. Overseas buyers may also search for an LDPE film blowing machine, blown film extruder, plastic film extrusion line or tubular film making machine.

Output, film gauge and width stability depend on the LDPE grade, additives, die setup, cooling conditions and winding settings. Other resin types are not confirmed by the source data and require a separate technical review and trial.
Integrated Process
- LDPE resin feeding and plasticizing
- Circular-die extrusion and bubble inflation
- Air cooling and film-width control
- Bubble collapsing and film guiding
- Tubular-film winding
Typical Applications
- LDPE tubular film for bag converting
- General packaging and liner film
- Protective film and selected agricultural film within the confirmed size range
- Custom LDPE film rolls verified through resin and product trials
Process Boundary
This line produces single-layer LDPE tubular film from compatible resin. It does not print the film or convert it into finished bags, gloves, aprons or other products. Printing, slitting, bag making, punching, sealing and recycling require separate equipment.
The source data does not confirm HDPE, LLDPE, PP, biodegradable resin, multilayer co-extrusion or food-contact compliance. These requirements must be reviewed and tested before selection.
