Specific Applications
The 2400 Type Three-Layer Co-Extrusion Blown Film Machine is used to produce multi-layer polyethylene film for packaging and industrial needs. Detailed applications include:
1. Production of film for supermarket flat bags, vest bags, and shopping bags that require good strength and sealing performance.
2. Manufacture of film for rubbish bags and garbage bags where multi-layer construction improves tear resistance and durability.
3. Supply of film for courier and express bags that need consistent thickness and surface quality for printing.
4. Creation of packaging film for food, stationery, garments, and general merchandise that benefits from layered structure.
5. Production of film rolls that feed downstream bag-making machines for continuous-roll or individual bag conversion.
6. Industrial packaging film for protective wrapping and light industrial applications within the thickness range.
These applications focus on volume film output for packaging converters rather than specialty medical or high-barrier barrier films.
Core Functions
Core functions of the 2400 Type Three-Layer Co-Extrusion Blown Film Machine center on stable three-layer film extrusion and winding:
1. ABC three-layer co-extrusion with rotating die head for uniform layer distribution and reduced film thickness variation.
2. Screw diameters of Φ75 / Φ85 / Φ75 with screw speed up to 100 r/min for controlled material melting and output.
3. Dual-lip air ring (1200 mm diameter) combined with body cooling for effective bubble cooling and film stability.
4. Haul-off system driven by 15 kW Delta inverter for consistent film take-up.
5. Fully automatic computer-controlled reel change on the winding unit for continuous production with minimal downtime.
6. Siemens Bede main motors (37 kW / 55 kW / 37 kW) and national-standard hardened gearboxes for reliable drive performance.
Purchase Motivations
Buyers typically choose the 2400 Type Three-Layer Co-Extrusion Blown Film Machine for three practical business reasons. Companies launching or expanding their own brand of packaging film use the machine to control film quality, layer structure, and consistency without depending on external film suppliers.
Manufacturers focused on bulk retail or wholesale supply install the equipment to meet steady demand from bag makers, printers, and packaging converters for multi-layer polyethylene film.
Cost optimization is another key driver: in-house three-layer film production reduces outsourcing costs, shortens supply lead times, and lowers unit film cost once volume reaches efficient levels. The automatic reel change and stable output range help factories balance capital investment against daily operating efficiency.
FAQ
Q1: Does it feature automatic winding?
Yes. The winding unit includes fully automatic reel change under computer control.
Q2: Is OEM/ODM available?
Wenzhou Chaoshun Machinery Co., Ltd. offers OEM and ODM options. Specific customization requests should be discussed directly with the factory.
Q3: What are the main drive components?
Main motors are Siemens Bede (37 kW / 55 kW / 37 kW), with national-standard hardened gearboxes and Delta inverter on the haul-off section.
